Why Roberto Coin’s jewels have a hidden ruby?

We thought it was a known story: instead the reason why a ruby ​​is hidden in Roberto Coin’s jewels is not known by everyone. Yet the idea of ​​inserting a small ruby ​​inside the jewelry is undoubtedly a distinctive aspect of the Italian brand.

Therefore, the idea of ​​ruby ​​as a symbolic signature of the Maison of Vicenza is linked to mythology. Roberto Coin, driven by a passion for ancient history, many years ago read three stories related to the stories of the past that sparked his imagination.

The first of these legends belongs to the world of ancient Egypt and to the pharaohs: the ruby ​​was considered a sort of amulet, which worn in contact with the skin guaranteed eternal love, eternal joy and eternal health. The second legend, however, concerns the Burmese warriors. Apparently they wore the red gem in contact with the skin to defeat wounds and death during the battle. Finally, an old Hindu myth considers rubies to be the precious fruits of Kalpa, the sacred tree of desires and hope. In short, ruby ​​as a magic stone, perhaps associated with life for its blood color.

Fascinated by these myths, Roberto Coin therefore decided to associate his brand with ruby. So in 1996 the launch of the Appassionata collection marked not only the beginning of the history of the Roberto Coin brand, but also the principle of its signature: a small ruby ​​set for the first time within the jewels of the collection. A signature that has remained a hallmark of the Venetian Maison.

How much is your stone worth?

How much are the stones in your jewels worth?

Raise your hand if you don’t have at least one jewel with colored gems and have never wondered how much that stone is really worth. Amethyst or ruby, emerald or citrine, sapphire or moonstone: there are not only diamonds. But how much are colored stones worth? How much is a ruby ​​worth? Or an emerald? Or, again, aquamarine? If you want to know how much the gem you have set on the ring is worth, or in a necklace, earrings or bracelet, read here. We try to explain in a simple way what are the characteristics that determine the value of a colored stone.

Filippo G&G, pietra ametista e di diverso tipo
Filippo G&G, gems of different types

Of course, there is immediately a fairly obvious aspect: in general, the value is determined by how rare a gem is. A ruby, always in principle, has a higher value than a simple citrine quartz. But this is only a starting point. In fact, it is not said that in reality this is the case. Let’s see, instead, what are the criteria that guide the evaluation of a precious or semi-precious stone.

Anelli con pietra di colore by Bulgari
Bulgari gemstone rings

The starting point is that the value of a colored stone depends on several factors, not just one. Hence, the estimated price doesn’t just depend on the weight and volume of a stone. So, as we said, it is not even the type of stone that determines its absolute value. If you have a ring with a sapphire, it is likely to have a value greater than that of a moonstone. Probable, but certainly not. For example, diamonds are also used in industry, since they are the hardest material that exists. And, of course, the diamonds used to cut ceramic tiles are not of the same quality as those found in jewelry. This is to make it clear that the same type of mineral can have very different qualities.

Earrings in gold, diamonds, colored gems

The 4C
As with diamonds, precious colored and semi-precious stones are also valued for the classic 4C: color, clarity, cut (in English cut) and carat weight (which also determines the size). But among these 4C the first is the most important: the color. Of course, let’s talk about colored stones.

Gemme per Liaison de Couleurs
Paul Wild, gems for Liaison de Couleurs

Color
For precious (emerald, ruby ​​and sapphire) or semi-precious (all others) colored stones, the color is assessed with three different criteria: hue (name of color), tone (darkness and brightness) and saturation (vividness) . The relationship between hue, tone and saturation is the most important aspect for evaluating a colored stone. This is why emeralds (or rubies, sapphires, etc.) are not all the same. In general, when a gem has a more saturated color it will also be darker. To obtain a more saturated color, the stones are often subjected to particular processes: for example, they are subjected to intense heat, radiation, or treated with chemicals (not harmful). Natural stones, untreated, have a higher value, obviously with the same appearance and weight.
But if you want to observe what the exact color of your stone is, pay attention to the light source: a light bulb that illuminates with yellow hue, for example, can make your stone appear in a different shade than the natural one.

Clarity
Usually the stones, some in particular such as emerald, are not as clear as a glass crystal. Clarity measures the degree of internal or surface transparency. Inside the stones there may be inclusions, that is, small imperfections, traces of other minerals that can determine their value. Usually, the fewer inclusions there are, the more the gem has value. But, be careful: if they offer you an absolutely clear emerald, look at it with suspicion. It could be synthetic. In contrast, amethysts are generally free of inclusions. Other stones, on the other hand, are appreciated precisely for their inclusions: for example, the cat’s eye. Or the star sapphire, which has that particular reflection precisely because it has a rather rare inclusion.

Zaffiri e rubino
Blue, pink, yellow and ruby sapphires

Carats (weight)
Size matters. Of course, the color is important, but if the gem is tiny … The weight of the colored stones is indicated in carats. Yes, but what is it equivalent to? Quickly said: a carat is about a fifth of an gram. A gem with higher carats will generally cost more than another smaller, if the quality is equivalent. But the proportion is very different: amethysts are also found in relevant sizes, even over 100 carats and, therefore, the difference between different sizes and weight is relative. Large rubies, on the other hand, are very rare: in proportion, their value with respect to weight will increase more than that of amethyst.

Paolo Costagli, white gold ring with an oval cut aquamarine and diamonds

Cutting
It is not easy for anyone who is not a gemologist to judge whether the cutting of a stone is correct. But you have to know that in evaluating a gem it also matters how it was cut. The light, in fact, will be better reflected and will make a well cut stone brighter. Proportions, symmetry and polishing are the main aspects. On the price of a gem, however, its shape has less influence, if it is one of the classic cuts used, such as brilliant, emerald, shuttles, etc. A good cut can enhance the nuances of a colored gem. An imperfect cut can, on the contrary, depress its beauty. And do not think that the cut is a simple operation performed automatically: each stone is different from the other and a cut that is good for one may not be suitable for a similar one, but not the same.

The country of origin
Last thing to consider: the stone passport matters. There are mines that have a better reputation and average quality than others. And, therefore, in evaluating the stones it is also important to know what the origin is. Burmese rubies are more valuable. The emeralds of Colombia are the most requested, followed by those of Zambia. The now unavailable blue sapphires of Kashmir are the most sought after.

All about ruby

Rubies are one of the most loved gemstones for centuries and are the gem of the month of July. But few know its true characteristics. Here is a quick guide to know all about rubies

Bright, red, expensive: the rubies are one of the four minerals classified as gems, along with diamonds, sapphires and emeralds. Beware, though: they are very rare. They are often used other gems like ruby red but usually of lesser value. Have you ever wondered why it is called ruby? Simple: the name of the stone comes from the Latin word ruber, red. Want to know all about rubies?

Ring in white gold with an unheated emerald cut ruby of 6.54 carats

What are. Dispelling a myth: not all rubies are just red. The color varies from red to deep pink. According to science, the rubies are a variety of corundum, a mineral composed of aluminum oxide. But from a chemical point of view the color red is induced by the presence in its interior of chromium. From a mineral point of view, the ruby is a relative of another precious stone: the sapphire, that is also a corundum. So much so that sometimes it is difficult to determine whether a gem is a ruby or sapphire. For example, a ruby with a color not too strong sometime is classified as a pink sapphire. The rubies are used in jewelry, but not limited to: the stones are very rare, almost like a diamond.

Pigeon blood ruby, unheated

Look inside. Within a ruby you can find an asterism: this is a point bright three-or six-point or star that is caused by inclusions of rutile. This type of rubies is cutted into cabochons to display the effect of light. The asterisms are visible properly with a single source of light: they give a sense of motion and are much appreciated.

I riflessi del rubino
The reflections of the ruby

The provenance is important. The rubies are found in many parts of the world, but those of Mogok Valley, Myanmar (Burma) are the most prized for their intense red color. Rubies are also found in Thailand, Cambodia, India, Afghanistan and Pakistan. In Sri Lanka are usually light pink (pink sapphires are often classified). Small deposits of rubies are also found in Tanzania, Madagascar, Vietnam, Nepal, Tajikistan, and even in the United States. Today, however, Africa is the main source of rubies. An estimated 80% of the rubies come from Mozambique, mainly from the Gemfields mine. But other companies are also active, such as Fura Gems, which began auctioning gems in the last year, along with a third competitor, Gem Rock, which will soon enter the ruby auction market. However, Africa, as a source, has traditionally been despised by industry, especially for rubies: the most valuable gems, in fact, are those from Burma. But with Burmese rubies in short supply, African rubies from Mozambique, Madagascar and Tanzania are on the rise. Therefore, it is better not to focus on the origin: it is better to judge the value of the stone itself, whatever the origin.

How are. Weight, color and quality of the stone determines its value. First of all the color is important: those with a very intense and brilliant red are the most wanted. Their color is described as “pigeon’s blood”. Rarely rubies can also change color or submit an effect “cat’s eye”. It is also important to their degrees of clarity: a ruby without inclusions are very rare, especially over a certain size. A 10-carat ruby without any needle-like rutile inclusions (also called silk) may indicate that the stone has been treated, or is exceptional.

Treated or natural? Because the imperfections are common in virtually all rubies, they are used by gemologists to tell if a stone has been treated or is a synthetic ruby​​. The treatment, in most cases consists in heating the raw stone before it is cut. In fact, almost all rubies today are treated in some way, usually by using the thermal method. For this rare untreated rubies and good quality can reach very high prices.

Ruby record of 34.8 million

Here is the most expensive ruby in the world: it is called Estrela de Fura and was sold in New York by Sotheby’s for 34.8 million dollars during the Magnificent Jewels auction. The stone weighs 55.22 carats and is the largest gem-quality ruby ever to appear at auction. The previous world record was held by the Sunrise Ruby, a 25.59 carat Burmese one also beaten by Sotheby’s in Geneva, in May 2015, for 30.3 million dollars.

Estrela De Fura, 55.22 ct

Estrela de Fura was made from a rough ruby weighing an exceptional 101 carats, discovered and extracted in July 2022 in the Fura Gems ruby mine in Montepuez (Mozambique), one of the largest ruby deposits in the world. Its quality makes it a particularly rare ruby.

The outstanding result obtained today is not only a source of pride for us, but represents a milestone in the incredible journey of our company which, in just five years, has grown in an extraordinary way. Today, thanks to Estrela de Fura, we have gone down in history: we have set a new world record by selling the largest and most precious colored stone ever presented at an auction. With its 55.22 carats Estrela de Fura is a true wonder of nature, a sensational stone, with perfect color and exceptional clarity that fully represents the extraordinary quality of Mozambique rubies and sets a significant precedent for Mozambique rubies, elevating them to the state of those Burmese. This stone was a gift of nature for Fura, a gift that is granted only once in a lifetime, an acknowledgment of the hard work that the whole team carries out every day. On this occasion they cannot fail to thank the communities and the Government of Mozambique for their continuous support.

The Eternal Pink and other jewels

Sotheby’s Magnificent Jewels auction also had other exceptional pieces up for sale, such as The Eternal Pink, the most vivid pink diamond to ever hit the market, which sold for 34.8 million. In total, the auction reached $95.9 million, the highest figure ever for any jewelry auction ever organized by Sotheby’s in New York. It was also the first auction with two gems selling for over $30 million in the same sale. 91% of all lots found buyers, with over two-thirds of lots sold fetching prices above their high estimates. The sign of the times: more than a third of the lots were purchased online.

Today’s record result is a direct reflection and further confirmation of Sotheby’s position as the market leader at the top level of the global jewelery industry. We are honored to have brought to auction this exceptional selection of jewels, anchored by several private collections with historic provenances, which includes high quality diamonds, superlative colored gemstones and designer jewelery from the most esteemed houses. We look forward to continuing in our tradition of offering the rarest and most spectacular jewels to our worldwide clientele; this remains at the heart of what we do at Sotheby’s.

The Eternal Pink was the other major attraction of the auction. The vivid pink diamond set a new record price per carat of $3,292,763, which is now the second-highest price per carat for a pink diamond, just after the Williamson Pink Star, which sold for $57.7 million at Sotheby’s Hong Kong in October 2022.

Among the other magnificent jewels on sale were 11 pieces from the collection of Constance Prosser Mellon and Constance Barber Mellon, sold at 100% for a total of 6.9 million. The collection included a sapphire and diamond ring by Cartier, which fetched $3.3 million after a lengthy five-minute battle between eight bidders. Weighing 33.51 carats, this extremely rare sapphire is of classic Burmese origin, has no indication of heating, and possesses a royal blue color. Also from the Constance Prosser collection, a magnificent sapphire and diamond necklace created by Cartier in the 1950s has found a buyer for $2.8 million. The necklace is set with five Kashmiri sapphires, totaling approximately 34.95 carats, and is further accented with round, baguette and square cut diamonds.

Faidee’s dream rubies


x



Roop Chand Lunia. It may be that this name means nothing to you. Yet he is linked to the world of jewelry: Roop Chand Lunia, born in 1895, he is considered the king of the Burmese ruby. It was he, who passed away in 1960, who founded Faidee, a high-end jewelery house specializing in rubies. Roop Chand Lunia was a gemstone trader, known for his collection of rare and exceptional stones. But he especially fell in love with the red Burmese gem, one of the rarest and most valuable. For this reason, the company founded by Roop Chand Lunia is called Faidee, a name that means good luster, shining, in the Thai language. Faidee specializes in one stone, the ruby: it offers the most colorful, impressive and, of course, expensive gems.

The scarcity and rarity of Burmese Pigeon’s Blood rubies have made them one of the most sought-after gemstones in the world. Now in its fourth generation, Faidee therefore offers great jewels with splendid rubies and diamonds. The descendant of the founder, Rajeev, for much of his youth learned to cut and classify diamonds to continue his great-grandfather’s legendary legacy. Today Rajeev guides the skilled craftsmen of Faidee in the processing of the rough stones up to the final polishing.

The rarest ruby in the world up for auction at Sotheby’s

One of the rarest and most valuable rubies ever is about to be auctioned by Sotheby’s. This is the gem extracted in September 2022 from the Fura Gems ruby mine in Montepeuz (Mozambique). The ruby received the name of Estrela de Fura (star of Fura in Portuguese) and weighed 101 carats when mined. It is a record ruby: not only extremely rare in terms of quality and colour, but also the largest, gem quality, ever discovered and the most precious ever auctioned off. It will be offered for sale by Sotheby’s during the Magnificent Jewels auction in New York on June 8th.

The ruby has an estimate in excess of $30 million. The rough stone was transformed by a group of craftsmen into a magnificent cushion cut stone weighing 55.22 carats, is preparing to rewrite history by surpassing the Sunrise Ruby, a 25.59 carat ruby of Burmese origin, sold for 30, $3 million (over $1,185,000 per carat) at Sotheby’s in Geneva in 2015 and which still holds the world auction record for a ruby. The world tour of Estrela de Fura, which departed from Hong Kong on April 5, will tour the world in recent weeks to arrive in Geneva (the only European stop) in May, before becoming the undisputed star of the New York auction.

How hard are jewelry stones?




How resistant are the stones of your jewels? Can they be damaged easily?

The hardness of gems is measured by the Mohs scale. The name derives from the German scientist Friedrich Mohs, who conceived it in 1812. The Mohs scale assigns a grade from one to ten to the degree of hardness of the stones. In this way, you can know which ones are more delicate, for example, which scratch or break more often. It is an aspect that is best known to avoid nasty surprises: knowing how hard the stones of your jewels are is also useful for cleaning. For example, an opal is not as strong as a ruby ​​and should be treated with greater delicacy.

Gemme di Filippo G&G

In short, generally when someone buys a piece of jewelry they don’t ask you if it will be tough enough to withstand occasional bumps. Yet it is a question that is best to ask yourself, especially if the stone is mounted on a ring, a jewel that is more easily subject to contact with other materials. But the same goes for earrings or necklace if these jewels have stones.

Although we tend to believe that a stone is incredibly more solid than any common object of everyday life, this is not the case. The gems of your jewelry could be fragile stones, at risk of being scratched or even shattered in some unfortunate circumstance. Even the diamond is absolutely not safe from all danger. Fortunately, Mohs took the trouble, almost two centuries ago, to measure the hardness of different minerals, including precious stones. It is therefore possible to know the degree of hardness of the stones with some certainty.

The Mohs scale was initially based on ten readily available minerals. This ranking was subsequently completed and is now an important indicator for those who buy a stone. But be careful: it is a special scale. For example, a corundum (such as ruby) is twice as hard as a topaz, but a diamond is nearly four times harder than a corundum. What you see on this page is a table that summarizes the hardness of the main stones. At the head is the diamond. Immediately after there are rubies and sapphires. Then … Federico Graglia

Gems that look the same




Beware of false friends in jewelry. Or, better, don’t buy stones that have different values, but a similar appearance. Similar, but not the same. Yet, not only authoritative gemologists have fallen into the misunderstanding, but also customers willing to pay figures with many zeros and even crowned heads. Do you want an example? Numerous precious stones belonging to the treasury of Tsar Peter I of Russia, long believed to be rubies, were later classified as rubellite. The same gem, the ruby, also fooled the London royals: the so-called Black Prince Ruby of about 170 carats mounted on the British imperial crown is actually not a ruby, but a spinel, placed next to the Cullinan II diamond, this authentic . In short, stones with the same color and quite similar. But one is worth more than the other.

Ruby and spinel. Both are red stones, although the spinel can also take on other shades, for example these stones can also be black. Many spinels used in jewelry have a color and clarity very similar to that of ruby ​​and sapphire (two stones that are varieties of corundum). Not only that: spinel is often found in deposits adjacent to those of these two most precious stones. In addition to the deep red spinel, there is also a raspberry-colored variety that is mined in Tanzania.

Ruby and rubellite. Rubellite is another red stone, which can have an intense hue similar to that of certain rubies. However, it is a variety of tourmaline, a less rare gem than rubies. Rubellite was already known in ancient Roman times and the gem was often confused with garnets and spinels. The great diffusion in the West took place at the beginning of the seventeenth century after the Dutch importation of the rubellite from Sri Lanka. In 1998 a large tourmaline mine was discovered in Nigeria and rubellite invaded jewelers.

Spinel and taaffeite. Between these two stones it is taaffeite that is rarer and more expensive. Taaffeite is named after its discoverer, the Irish Richard Taaffe, who in 1945 identified it as confused with spinel. Sent to London for analysis, it was identified as a new precious stone, unfortunately very difficult to find. Unlike spinel, taaffeite exhibits the property of double refraction which allows the distinction between these two minerals. It can have different colors, including red, violet and red, which make it very similar to certain varieties of spinel.

Diamonds and zircons. Attention, let’s not talk about cubic zirconia, which are artificial stones with a very low price and used for pendants and bijoux that cost a few tens of euros or dollars. Real zircons are natural stones. They can have different colors, often found in the blue hue, but there are also colorless zircons like diamonds. Furthermore, zircon has a very high refractive index, lower only than that of diamond, and for this reason it has often been mistaken for the gem it resembles. From a chemical point of view, however, diamonds and zircons are different: the former are made of pure carbon, the latter are nesosilicates.

Zircone taglio brillante

Emerald and demantoid garnet. They are both green stones. The demantoid garnet, just like the emerald, takes on the green hue due to the percentage of chromium and iron, which lead to bright green shades or more tending to green-yellow, even green tending to blue. Another variety of garnet, tsavorite, also has a green hue that can be mistaken for emerald. In fact, many jewelers combine the two stones on the same piece of jewelry to lower the cost.

Topaz, quartz, aquamarine. Sometimes white topaz or topaz with faint yellow hues is mistaken for smoky or citrine quartz. Obviously a simple quartz costs less than topaz. In the blue hue, on the other hand, a pale-colored topaz can be mistaken for an aquamarine. The value of the two stones, however, is different.

Of course, a very precious jewel must be kept with care and, frankly, if it has a great value, even emotional, it is better to take it periodically to the jeweler, who can also check its state of health: it happens, for example, that the stones can be detached. , or that the surface is covered with scratches. But it is not always necessary. You can (indeed, must) clean your jewelry periodically, just like washing your laundry. A jewel, in fact, is almost always in contact with the skin and is covered with an opaque patina due to the natural fat that comes out of the pores, and even worse it can be ruined by perfumes, creams and lotions used regularly. Here, then, are the tips for cleaning jewelry to perform at home.

ring

Unlike silver, for example, gold does not blacken over time, but it can easily accumulate dust and dirt. The same goes for diamonds which, of all gems, have the greatest ability to retain organic fragments. And so jewelers are horrified when customers bring rings to tighten or widen, earrings to fix, and wonder why they don’t wash them like their clothes. You can restore the luster of jewelry by yourself, just a few household tools and a few ingredients.

1-detersivo
1 Pour a few drops of liquid dish soap into a bowl of water that is just over warm, but not hot. Gently mix. Even if normal tap water works well, for even better results, you can use soda-free soda water: carbon dioxide gives rise to a process, carbonation, which in surfactants, i.e. detergents, helps to dissolve dirt. and accumulated debris. Do not use very hot or boiling water because some stones, such as opals, pearls and corals, can break with a rapid and drastic change in temperature. Then, soak for about 15 minutes to allow the solution to penetrate otherwise hard-to-reach cracks and crevices.

wash

2 Gently scrub the jewelry with a soft bristled toothbrush, the softest possible (there are specific products, but a toothbrush or eyebrow brush will be fine), to avoid scratching the surface. Attention, stiff bristles may remove the top layer in the case of gold plated or galvanic treatment jewelry. Particular attention should be paid to very sensitive and soft stones, such as opals, or pearls.

3 Rinse in running water (always lukewarm) to remove the last residues, remembering to cover the drain plug with a pasta or metal filter coffee sieve. Domestic accidents are more frequent than imagined and even the ring or earrings in the sink pipe are a classic! One last consideration. Let the jewelry dry completely before wearing it again: if it is still wet, even slightly, it can retain moisture on the skin and cause mild skin irritation.
rubinetto

There is another method, that of toothpaste, useful for traveling or for everyday jewelry

1 Mix a small amount of toothpaste and water in a bowl to make a smooth paste.
2 Scrub with an old soft-bristled toothbrush.
3 Rinse thoroughly.

But if the dirt remains, before trying more radical methods such as boiling water or ammonia, which we strongly advise against, it is best to consult a professional.

Why precious stones are heated?




Precious and semi-precious stones in the great majority are heated at high temperatures. Or subjected to radiation. That’s why

If the precious stones warm your heart is perhaps because in turn have been heated. Not from your eyes, but from an electric furnace which can reach 1,600 degrees. The thermal treatment of precious and semiprecious stones is known to jewelers and gemologists, but little known to the general public, that is, those who buy jewelry that flaunt jewels of deep red, deep blue sapphires, aquamarines transparent. In fact, the colored stones that are sold as natural are a small minority, most end up in the oven, without the intervention of a chef. We see, then, what is the heat treatment of gemstones.

Warm color
The stones are heated above all to bring out the colors. During treatment the stone is heated to very high temperatures (up to about 1600 degrees Celsius). At this temperature the inclusions (small amounts of other minerals) present in the stone melt and add their own color to the stone. Usually, therefore, the heated stone becomes darker, of a more intense hue. This is the case, for example, of rutile in the blue sapphires. There are also sapphires, known as Gouda, which are extracted from the ground milk and white sapphires turn blue when heated. Even the rubies are almost always heated (except exceptions): with the heat the aluminum oxide in the stone creates a new crystalline structure and the chromium is combined in a different way, allowing a better shade of red. Another effect of the heat is that it can improve the transparency of the stone, thanks to the destruction of any gas or fluid inclusions.

How to find them
Do you have a ring with a natural stone or heated? The question should be: what does it matter? But if you are curious to know, you must contact a gemologist with a microscope. And even so will not be easy to find out. The gemologists, however, can examine the internal state of the stone, inclusions, and look for signs of heat treatment. In general, if the stone is perfect or has exceptional value, or has been treated.
What stones are heated
Here the stones more easily end up in the oven: amethyst, citrine, ametrine, aquamarine, tourmaline, topaz, sapphire, ruby, tanzanite, blue zircon.

Irradiation

In addition to being heated, precious and semi-precious stones can be subjected to radiation. The question is: are they dangerous then? No, no problem: they are under strict control, just like when you go to the hospital for a chest screen. And, in any case, before leaving the laboratory the stones are checked to ensure that they do not emit dangerous radiation. After all, many gems are naturally subjected to radiation when underground. The irradiation that takes place in the laboratory serves to strengthen or change the color. A stone often subjected to radiation is blue topaz, which in nature is found with a very light shade. Often the two treatments, the thermal and the radioactive one, are combined: each one manages to improve a different aspect of the stone.

Fabergé celebrates the anniversary of Game of Thrones




What do the famous Fabergé eggs have to do with a fantasy that has kept millions of people glued to the TV? Yet, the high jewelry of the Maison famous for its precious eggs that cheered the tsars, has decided to celebrate the anniversary of the first episode of Game of Thrones, which debuted just ten years ago. For The Iron Anniversary Gemfields, a mining company that has held the Fabergé brand since 2013, has decided to collaborate with Warner Bros. Consumer Products to produce the Game of Thrones Fabergé egg, defined as imperial class.

To create the jewel, Fabergé designer Liisa Tallgren collaborated with Game of Thrones costume designer Michele Clapton. The egg design is inspired by the character Daenerys Targaryen, played by actress Emilia Clarke. The egg shape is inspired by the protagonist’s journey and the importance of her color in her costumes, her passion for dragons and how she interpreted her messages through her jewels during his trip to the show. The egg scales are hand painted in purple, red, blue and gray enamel, the color scheme of the character’s costumes, and accented with diamonds and moonstones.

The jewel is made of 18 karat white gold, with a dragon that surrounds the base of the egg, dotted with white diamonds. The egg opens into three sections, representing the three dragons of fantasy, while the flaming scales are represented by a pavé of deep red rubies at the bottom and shaded in pink sapphires and white diamonds at the top, with colored gems that stand out from the black rhodium plating on white gold. Inside, there is also a second golden egg, with white diamonds set. Finally, inside this smaller egg, there is a miniature crown on a crystal base, set with a pear-cut ruby ​​from the Montepuez ruby ​​mine of Gemfields in Mozambique.

Francis Chiu, Thai message

/





The precious jewels by Francis Chiu, signature of the classic Thai design ♦ ︎
It is no secret that much of the jewelry and high jewelery of large European Houses is made in Thai workshops and factories. The manual skills of the craftsmen of the Asian country, combined with a lower labor cost, has led several brands to rely on the industrious Thai workers. But, apart from producing jewels for third parties, what are they capable of doing? It is worthwhile, as an example of the ability to create jewelry of great value, to look at the work of Francis Chiu.

Anello in oro rosa e morganite
Anello in oro rosa e morganite

His professional history began in 1999. When most of the Thai jewelry companies focused on mass jewels, Francis Chiu chose to create an exclusive jewelery brand in Asia, for the most demanding public. Today its jewels are also appreciated in the West and are also sold through international auction houses. They are jewels based on large and considerable precious stones, from rubies to sapphires, to which jade is added. Around these stones, always of great impact, the jewel is built. The style is classic, sometimes with some concession to oriental taste. Margherita Donato

The rich style and a lot of tradition in the jewelry of the Varda Goelka and her Diagold ♦

India is the country that loves most jewelry. It is logical, then, that has a long tradition. But there are also new brands, as Diagold, that without renouncing of tradition, now offer jewelry high class, with a style that also likes to Western women. In fact, Diagold opened a shop in London. If you go to India, any case, you can go to visit one of the stores (Kolkata, Mumbai, Delhi), of this brand, which was founded by a woman, Varda Goenka, about 15 years ago.

It is not about ethnic jewelry: stones and materials go through a selection equal to that of the great Maison West. Just look at the jewels proposed by Diagold to realize immediately that the model that inspired jewelery is classic Italian or French, with an obvious imprint in some eastern parts. All the jewels are still very elaborate, with extensive use of colored stones next to diamonds and pearls, while gold is yellow, the color that is most appreciated by the Indians. This selection of branded jewelery Diagold can give an idea of ​​the style of the brand.

Van Cleef & Arpels shows Jasmin, new solitaire

/

An engagement ring or a wedding ring are the symbol of a promise that lasts over time: and it is this message that Van Cleef & Arpels entrusts to the history of its jewels.

The Parisian Maison has summarized the history, evolution (with a new ring) and style of its creations or, more precisely, of the engagement rings and wedding rings. A story that starts in 1895 in the heart of Paris, with the marriage of Estelle Arpels, daughter of a precious stones trader, and Alfred Van Cleef, son of a gem cutter. In 1906, at number 22 of place Vendôme, the Maison Van Cleef & Arpels unites these two names in a common destiny under the banner of jewelry. Since then, as a sort of immutable link, the logogram & symbolizes this union of souls and skills.

For diamonds, as for sapphires, rubies or emeralds, Van Cleef & Arpels seeks, in fact, not only excellence, but also character. In addition to the absolute criteria, a meeting occurs, a secret alchemy capable of awakening the senses. In particular, with Le Pierres de Caractère (which is a brand of the Maison).

From the pearl and diamond set offered to Princess Grace of Monaco as a wedding gift to the solitaire adorned with a fabulous 8.25 carat ruby ​​given by Richard Burton to Elizabeth Taylor in 1968, from the famous ruby ​​and diamond necklace of the Duchess of Windsor who has the inscription “My Wallis from her David, 19.VI.1936” on the clasp, at the Océan set made for Princess Charlène of Monaco for the wedding in 2011: many famous couples have turned to the Maison in order to celebrate the highlights of their love.

The Rings
Each creation benefits from Van Cleef & Arpels’ High Jewelery experience, handed down for over a century by the Mains d’Or (another brand of the Maison) of its ateliers. This competence is expressed through a succession of meticulously hand-made gestures. And this also applies to collections of wedding and solitaire rings.
The Icône and Couture solitaires wrap the central stone in a tender embrace, while the Perlée and Estelle rings are punctuated by a profile of gold or platinum pearls. Bonheur and Romance creations sublimate the beauty of the diamond thanks to a feminine and timeless aesthetic. The gems also shine on the unique solitaires, evoking the bond with your loved one through the caress of a volute or a precious petal.

The new Jasmin solitaire
Bonheur, Jasmin, Icône, Romance, Menuet, Entrelacs, Motifs Pétales or Boucle: the different frames allow to highlight the Pierres de Caractère selected by the Maison. The new Jasmin Solitaire is part of these criteria of jeweler excellence. Inspired by the jasmine flower, a symbol of love and beauty, this model with a delicate curvilinear trend is adorned with marquise-cut diamonds to evoke a poetic nature. The solitaire is made of platinum, rose gold, a cushion cut ruby ​​of 5.02 carat (Thailand), round cut diamonds and shuttles.

Customization
In order to easily combine the engagement ring with the wedding ring, the Maison has conceived its creations so that they harmonize with practicality and elegance. If some models (Romance, Couture, Perlée, Estelle) are made on purpose, others offer numerous combinations to future spouses. The ensembles can, in fact, be composed according to their own personality: classic and timeless or modern and daring. Playing on the width of the rings, combining simplicity with the brilliance of diamonds, combining gold pearls: the possibilities are manifold. The Maison also offers future spouses the opportunity to customize each engagement or wedding ring through an exclusive engraving.

Real and false stones, how to recognize them





How to recognize a real stone from a fake? Some tricks are often used for jewels and can deceive those who are not experts. Here’s what to check ♦ ︎

Beware of false stones. But also to those who are half-faked. Perhaps you do not know that the ways to simulate precious stones on jewels are many. Here are some aspects you need to consider.

Analisi di un diamante
Analisi di un diamante

False stones. Plastic and glass are materials often used to simulate precious stones. Technology today allows you to create something in the laboratory that is not distinguishable from stones such as rubies or fossil resins such as amber. Naturally, an expert jeweler or a specialized laboratory can identify whether they are authentic stones or imitations. If you have doubts, ask for an expert advice.

Orecchini oro e ambra
Orecchini in oro e ambra

Artificial stones. Cubic zirconia and synthetic moissanite (there is also the natural one, rather rare) are two of the stones created in the laboratory and which have characteristics similar to authentic gems, such as diamonds. Similar, but not the same. Of course, if you want to sell them, they have a very low value, but at the time of purchase, only a gemologist can distinguish a cubic zirconia, often passed through a zircon, which is instead a natural stone. How to be sure not to be cheated? Simple: a diamond, even a small one, always has a certificate attesting to its characteristics such as transparency, color, clarity and, of course, the carats. Cubic zirconia, no.

Composite stones. One of the trends among jewelers is the proposal to superimpose different stones or materials. It is a way to reduce costs: it consists of a kind of sandwich of different stones: which is more valuable is above, the one that serves to create thickness is below. The goal is to make the stones used on the surface appear larger, adding an imitation or a cheap gem, perhaps in the lower part of the stone, hidden by the setting. This system is less common for transparent stones, while it is more easily used in opaque ones, such as opals or turquoise. Sometimes the authentic stone is just a small layer that is glued onto a less valuable mineral. Another system, on the other hand, concerns transparent stones. To obtain an interesting shade, one expedient is to glue two or three different stones with a special invisible adhesive, so as to make them look like one and transform them into a “precious” stone with a fascinating nuance. The best brands do not hide this choice. But how to avoid cheating? In addition to relying on a brand that enjoys your trust, it is good to carefully observe, perhaps with a lens, the processing of the jewel.

Il diamante composito naturale-artificiale

Fantasy stones. Another idea of those who do not want to be transparent with those who buy jewelry is to change the name of the stones. If you read that a ring has an “oriental emerald”, for example, know that it is a green sapphire, which is less valuable. Other examples: an “American ruby” is actually a garnet, which is worth much, much less. And the “Australian jade”? It is simple treated quartz. Conclusion: when you read slightly exotic names of stones, which you have never heard, check on Google. Or on Gioiellis.com, of course.

Reconstituted stones. There are stones that are stabilized or rebuilt, as often happens in turquoise. Stabilization consists in subjecting the stone to a pressure to make it more compact and eliminate the chalky consistency. Furthermore, often turquoise or other soft stones are reconstituted by mixing powder with a binder. In short, they are a kind of pasta, to which dye is often added, to make the color more vivid.

How to defend yourself. It is not easy to recognize these tricks. A very low price is already an indication that something is wrong: no one will give you for less money a precious stone and the probability that a jeweler offers substantial discounts on an emerald, diamond or ruby ​​is as rare as water in the desert. The certificates, for very expensive stones, are a good start to avoid the purchase of fakes. The opinion of a jeweler who can guarantee the authenticity of a jewel is another element to keep in mind. Finally, greater security can it guaranteed by a expert gemologist. Giulia Netrese
