The A.Link’s diamonds

Published on August 21, 2023

The American Maison A. Link, specialized in the most loved stone by women: diamonds ♦

Diamonds, diamonds, diamonds: some people love jewels only if they revolve around the most popular gemstone. And this is the story of A.Link, a New York company that specializes in diamond jewelry. Does just that since 1904. It was founded by Adolph Link, jeweler from Vienna who emigrated to the US, which has brought the taste loved by the wealthy Europeans of the Belle Epoque in a nation that was growing rapidly. More than a century later, the company is still family owned, managed by Jeffrey Link and Douglas Sills in New York.

Adolph Link, it seems, was the first to study and sample the diamonds to get uniform quality of the stones. In this way the jewels have created a homogeneity and, of course, a more certain value. The company also boasts a special ability in the choice of the cut. In short, if you like diamonds, by A.Link you find to the full.

What are carats?

Published on August 9, 2023

How many carats is your diamond in? And how many karats is your gold ring instead? For those who are not a jewelry expert or do not know the basic rules of the world of jewelry, the carats are a big mess. The carats that are the unit of measurement needed for precious stones and pearls, in fact, are a completely different thing from the karats that refer to gold. Did you know? In English, everything is easier: the carats that measure diamonds start with the letter C while those for gold start with the K. In other languages, however, it is written the same way and everything is more complicated.

This is why we must be careful not to confuse the different concepts: the carats of diamonds (or rubies, emeralds, sapphires, etc.) with the karats that are related to gold. Here’s how to distinguish.

Diamante a cuore di Recarlo — Diamond in the heart of Recarlo

The carats of the stones

The carat (the abbreviation is ct) is a unit that indicates the mass of a stone or pearl. Carats are used for convenience, after in past each country regulated itself differently for centuries. For those who traded in diamonds or other stones it was therefore difficult to work. In Florence, for example, the basic unit of measurement was equivalent to 197.2 milligrams, while in London to 205.49. After much discussion, in the end, in 1907 it was decided to adopt 200 milligrams as a carat measure. A single carat, therefore, equals one fifth of 1 gram.

Anello con diamante bianco ovale da 31,82 carati — 31.82 carat oval white diamond ring

Now you know exactly how much the diamond on your finger weighs: divide the number of carats by five and you will have the weight in grams. Or, more easily, in milligrams, since it is not common to wear a diamond that weighs 5 carats (and therefore 1 gram). for this reason the carat is divisible into 100 points of 2 milligrams.

Anello di Van Cleef & Arpels a forma bombata con diamanti — Van Cleef & Arpels rounded shape ring with diamonds

By the way, why is the carat called so? The origin seems to be linked to carob seeds. The word carat derives from the Arabic qīrāṭ قيراط, which however is derived from the Greek kerátion κεράτιον, which indicates carob seeds. And these seeds were used to weigh jewels, thanks to their always regular shape. Then the term carat was used in Italy and later in the rest of the world. The use of the carat unit of measurement to weigh diamonds dates back to 1570.

The karats of gold

The carats of diamonds, precious stones and pearls refer to weight. The karats of gold, on the other hand, indicate the percentage of yellow metal present in a jewel, its fineness. The term karat has prevailed among the many systems adopted in the past and, in particular, on the measurement of pounds and ounces, which are still used for the weight of gold, platinum or silver. So why this confusion? Simple: the ancient origin of the word is the same, i.e. the carats used to measure precious materials.

Anello a fascia in oro 22 carati — Band ring in 22 carat gold

In the case of the karats that refer to gold, however, they indicate the thousandths of quantities of gold (or other precious metals) contained in an alloy. The maximum, as regards gold, is 24 karats. You will never find gold of 25 or more carats. The 24 karats indicate that the gold is 100% pure. The 24 karats are the basis for calculating the rest (always for gold). The 18-karat jewels, therefore, are 75% gold. It is calculated as follows: 18: 24 = 0.75. Similarly, a jewel with 14% gold means that it contains slightly more than half of gold, the rest are other metals (14: 24 = 0.58).

In some cases, the karats of gold can also be indicated with the number that refers to the percentage (the result of the arithmetic division). For example, 18-karat gold can also be indicated with the initials 750, 14-karat gold with 583 and so on. Again, if you read the number 375 in a jewel, know that it equals 9 karats.

The karats are also used for silver. The silver sterling, for example, contains 92.5% of silver and 7.5% of other metals, generally copper. It is generally referred to as 925 silver.

Little is known about the Bloch family of Antwerp. Yet from half century Bloch was one of the most popular jewelers in Belgium, but with a wide range of export market too. It is no coincidence that Antwerp is the European capital of diamonds and the Bloch family with diamonds has been uncomfortable for many decades. The company is led by the chief executive officer, Leslie Bloch, while managing director is Mickey Bloch. In short, everything in the family in an atmosphere of total discretion. And the headquarters, in Vestingstraat 59, in the city’s diamond district, is also completely anonymous.

Her mother and aunt owned the Boutique Menage at Trois on Madison Avenue, New York, and designed dresses for Diana Ross, Bianca Jagger, Barbara Streisand and Diane von Furstenberg. She, the founder of Ondyn, started making jewelry at the age of twenty. Her contemporary jewelry Maison uses diamonds and 14 or 18 carat gold, accompanied by diamonds set to form long threads that are used for necklaces, rings or earrings.

Sunrise: A Celebration of Graff Yellow Diamonds. Those who love yellow diamonds already know which door to knock on. But it is not that of the London flagship store, where Graff is based, one of the most famous brands for its range of diamond jewellery, also in the yellow version. The British jeweler has instead chosen the Paris store in Rue Saint-Honoré to exhibit his collection of yellow diamonds in a short exhibition. Alongside historical pieces, Graff also proposed a novelty: an exceptional high jewelery necklace.

It is a necklace that is worth a seven-figure and is composed of a 30-carat fancy intense yellow pear-shaped diamond, extremely rare, accompanied by another 138 carats of yellow and white diamonds. In addition to being an extremely precious jewel, the necklace is also the result of a long process. Each element has been created with careful craftsmanship with the aim of bringing out the central stone. Graff is a Maison famous for its yellow diamonds, such as the one called Stella di Bombay, purchased in 1974, a historic yellow stone cut and polished by Graff using innovative techniques for the time. Or Delaire Sunrise, a 118.08-carat diamond, or the Golden Empress, a 132.55-carat honey-colored diamond.

More and more artificial diamonds for De Beers

Published on June 24, 2023

Un diamante grezzo emerge dal reattore al plasma CVD di De Beers

If the diamond giant, the one who coined the claim “a diamond is forever” chooses to compete with itself, there is something strange. De Beers five years ago surprisingly launched the synthetic diamond brand Lightbox. Now the company, which is controlled by the Anglo American mining group, is relaunching. Basically, the brand most famous for its diamonds, since it extracts almost 30% of global production from the earth, will push on diamonds created in the laboratory, which cost less.

Punto luce di Lightbox — Lightbox necklace

At the basis of the choice is the declining price of natural diamonds. Although many believe that the gems most desired by women are a safe investment, which over time increases in value, the price of diamonds has fallen by about 20% from the highs of February 2022. Meanwhile, India and China produce an ever more synthetic diamonds, created in the laboratory, at ever lower prices. Fierce competition. For the uninitiated, diamonds produced in the laboratory are chemically indistinguishable from natural ones, even if an accurate analysis can determine the artificial origin of the gems. With the naked eye, however, no one is able to perceive the difference.

La nuova miniera: l'impianto di produzione in Oregon di diamanti artificiali — Lightbox (De Beers) Man-Made Diamond Oregon Manufacturing Facility

Precisely for this reason the total share of synthetic diamonds in a few years has gone from about 2% to almost 10% of the total according to some experts. And, at the same time, their price has dropped by 60%. But that’s not all, because according to some estimates, perhaps optimistic, if you look at the jewelry sector (i.e. those diamonds that are not used for industry) the sales of rings, earrings or necklaces with artificial gems would be close to 50% . The percentage probably refers to the diamond jewelery segment in the specific American market and not to the whole. But although it is difficult to understand how these estimates correspond to reality, everyone agrees that the sales of laboratory diamond jewelry is on the rise. And De Beers’ moves seem only an acknowledgment of reality. Even on the industrial front, things are not better: the Global Rough Diamond Price Index, relating to rough stones, is down by 18% compared to the all-time high it had reached in February 2022.

De Beers has therefore created a line of premium products, Finest, with laboratory diamonds certified in the same way as natural ones. In fact, even artificial diamonds can be of different quality. The certification is based on the same criteria used for natural diamonds, with the classic 4Cs. A further step by De Beers is the promotion with marketing actions of engagement rings with solitaire diamonds created in the laboratory, for now in the USA. Almost a blasphemy for those who love natural diamonds, created in the depths of the earth millions of years ago. And to think that De Beers at the debut of the Lightbox brand had underlined the unbridgeable differences between natural and artificial diamonds.

The War of the Diamonds

Published on May 21, 2023

news

So far the embargo on Russian diamonds hasn’t worked too well. In the future, however, things could change and the price of the gems most loved by women would inevitably become higher. The war in Ukraine unleashed by Russia had already provoked, in 2022, the announcement of an embargo against the exports of Alrosa, the Russian state diamond giant. But, in fact, precious stones continued to arrive in the West too, due to the difficulty of tracing the gems. In fact, rough diamonds are sold in countries such as India or Thailand, which do not adhere to the stop decided by Western countries on Russian stones. Europe alone in 2022 imported Russian diamonds for 1.4 billion euros. A considerable figure, albeit down from 1.8 billion in 2021.

Something could change after the G7, the meeting of the major industrialized countries, if China is not taken into account. In Japan, the heads of state of the G7 countries have decided to tighten controls more to reduce one of the sources of income of the Russian state. And Great Britain has announced that it will immediately leave Russian diamonds outside the borders, together with other metals that are exported from Moscow. Russia is now the world’s largest producer of diamonds. The problem, however, is how to control the stone market, which largely passes through channels that are difficult to monitor.

Where the traces disappear

The biggest obstacle comes from the steps related to processing. While the extracted diamonds are easily controlled, also thanks to the Kimberley Process, a path that certifies the origin of the gems, precisely to prevent them from financing warring countries or factions, the problem comes later. Cutting and polishing rough stones can make traces of provenance disappear. Furthermore, the idea of a real embargo opposes those countries, such as Israel or Belgium, which are the major centers where diamonds are cut.

On the other hand, those who have everything to gain from a stop at Alrosa are the producers of gems created in the laboratory, who can benefit from an inevitable increase in the price of natural diamonds. Synthetic diamonds, which are chemically the same as those extracted in mines, already cost much less than natural ones. If the price gap widened further, the advantage would be greater.

A $25 million blue diamond. This is what an anonymous buyer paid over the phone for the Bulgari Laguna Blu, auctioned by Sotheby’s in Geneva. The sale of Magnificent Jewels totaled $85 million, the highest value since May 2018 at the Geneva Jewelery Sales. The 11.16-carat fancy-vivid blue diamond is now the largest blue diamond in a Bulgari jewel and the most valuable Bulgari gem ever offered for sale.

Created in 1970 by Bulgari as a ring, when Bulgari was emerging as the most influential and innovative Italian high jewelery house, diamond is a rarity: it is an 11.16-carat Fancy Vivid blue, among the rarest gems in the world, it is a Bulgari signed jewel, and is unmodified, meaning that its current cut, produced in 1970, could be further enhanced by modern cutting methods to unleash its full potential as a gem.

Quig Bruning, Head of Sotheby’s Jewels Americas

It has been a privilege to witness the glamorous and exciting journey of the Bulgari Blue Lagoon over the past few months, knowing it was first created in 1970, up until its most recent appearance at the Met Gala where it dazzled on the red carpet, set in a Bulgari custom made necklace worn by Priyanka Chopra Jones. So, it is a special moment to see the journey of this extraordinary gem take yet another new turn, this evening in our auction room, into the hands of its first new owner in over 50 years. The Blue Lagoon sale surpasses the outstanding performance of our Magnificent Jewels and Noble Jewels sale which saw exceptional colored gemstones, particularly emeralds and yellow diamonds, surpass their high estimates, so spectacularly. There is no doubt that the Fine jewelry of the highest quality can still fetch sky-high prices.

The colored diamonds, or fancy, are the stars of international auctions. That’s why if you have a jewel with a big colored diamond you’re probably very rich ♦

Colored diamonds, or fancy, are the pièce de résistance of international auctions, reach very high estimates and often exceed them. Of course, these are remarkable material for hue, purity and weight, but all colored diamonds are quite unique, even when it comes to one carat stones: the inside impurities, during the process composition, color the stone in different ways (for the green is due to radiation, the blue is given by boron, yellow and orange from nitrogen molecules which absorb the blue light).

Fancy Vivid Pink Diamond di 13,15 carati — Fancy Vivid Pink Diamond, 13,15 ct

Certification is a valuable tool, as it lists all of those criteria, the 4 C, which determine the value. A kind of basic alphabet of which we have already spoken, which in the case of colored gemstones has different meanings generated by other factors. We must take into account that diamonds may have more colors together: some gems are pure, others have a secondary color, which gives them a shade. A fancy greenish yellow diamond will be a yellow stone with a green hue, while a light yellow-green diamond will have as a slight yellow tint. Can be confusing, but the secondary color comes before the primary.

Diverse sfumature di diamanti — Fancy diamonds

1 The first factor R. Rarity: only 1 in 10 000 is a colored stone. For their part, fancy diamonds are divided into three groups: browns, grays and yellows are relatively more common. The second group includes those with a more vivid yellow and orange shades. In the third, however, are those that have as their primary color orange, green, purple, pink and blue: they are extremely rare. So, although the secondary color it lower the value, a pure brown diamond will always cheaper than a pink diamond with a light brown tone. Finally, there are the red diamonds, but is a separate category, that even many jewelers have never seen.

Il diamante rosso Moussaieff — Moussaieff red diamond

2 The fifth C. The fluorescence, ie the color reaction of the stone of ultraviolet radiation, is generally regarded as a defect, and therefore affects the price. There are, however, exceptions: on the colorless stones from the H up (the scale of whites goes from D to Z, almost yellow) fluorescence becomes an advantage because makes the stones whiter. In colored ones it is something irrelevant a part from yellow diamonds, which must be nil or slight.

3 Carat weight steps. In general, the price of a diamond 1 carat is 25% higher than the value adopted for a stone of 0.90 carats of the same category. The difference increases with the increase of the quality and even reaches 70% with a D Flawless stone. In colored gemstones it gets further complicated: for example, an intense pink diamond from 0.50 carat can cost six times more than an equivalent from 0:20 carat, because its price per carat is much higher and the carat weight is the same 2.5 times higher. While in the range of lower color, such as pale yellow, the difference does not exceed 30%. So, everything depends on the intensity of the color.

Il diamante rosa Pink Star — The Pink Star pink diamond

4 Inclusions. A word that discourages the choice of a stone, despite having a beautiful color. According to experts, the best value is in the classification of clarity VS2. But this applies to colorless stones. Instead, in the case of colored diamonds SI1 and SI2, the inclusions are often invisible to the naked eye. Then, why pay more when the overall aesthetic effect is not compromised?

5 Cut. In specimens colorless serves to achieve maximum brilliance. Instead, in the case of diamonds fancy cut serves to get the most of the color, to exalt. An example: princess and round cut, because of the way they reflect light, attenuate the color, while the cushion or oval cut enhances the tonality. That’ why, the first cost much more than the latter, because they are rarer. And then the most sought after.

6 Setting. Even a less vibrant color can enhance with the set. For example, a pale yellow diamond with the griffes in yellow gold, will become more intense. The same applies to the brown and pink diamonds with the rose gold.

The unique jewels of Massimo Izzo, jeweler and sculptor of Syracuse inspired by tradition and the Mediterranean Sea ♦

About Massimo Izzo wrote also the New York Times. From Syracuse to Manhattan distance it is great. Yet the fame of the Sicilian jeweler is like the waves that start at one end of the earth and through all the oceans. The marine metaphor is no accident: the jeweler-artist is, in fact, an admirer of the waves and nature hidden beneath the sea surface. Most of his creations, celebrated around the world and sold in the two boutique in Syracuse and Milan, is dedicated or inspired by what the sea offers. Recently Massimo Izzo was invited by Elisabetta Cipriani gallery, London to create a series of works following his original aesthetic and superb craftsmanship which would further push his imagination and creativity. The result is six rings of great impact, made with blackened silver, sapphires and hypnotic opals.

Sciara, Blackened-silver, Australian opal, blue-sapphires ring

A truly amazing story, that of Izzo. Born in Messina, but grew up in Syracuse, he said that at 14 he was already fascinated by jewelry. Before moving on international stage, he start from the art school of the State of Syracuse, where he followed an experimental program in jewelery, and has worked for Salvatore Cassone, the largest jeweler in Syracuse. After learning the craft to the bottom, the Sicilian designer has soared thanks to an unusual order: the engraving of a silver plate on the occasion of the visit to the city of Pope John Paul II.

Blackened silver, Mexican Fire opal, orange sapphires ring

He has also worked with another famous Sicilian, the Oscar-winning director Giuseppe Tornatore, who commissioned the jewelry worn by Monica Bellucci in the film Malena. The jewels of the Sea collection are made in 18 carat gold and represent octopuses, sea urchins, crabs, starfish. All pieces are refined and processed rhapsody of colors and shapes, often using raw gemstones: resemble most to sculptures than simple jewelery. His work has been compared to that of another great Sicilian jeweler Fulco di Verdura, although the style is completely different. Sure, you can read in the work of Izzo a scent of Sicilian Baroque architecture that gave an impression of entire neighborhoods of the island city. And it is a style that has fascinated, according to his account, even Santo Versace, Tim Burton and JK Rowling. It is not hard to believe.

Are lab grown diamonds sustainable?

Il diamante da 110 carati con cui è stata realizzata la collana

Are natural diamonds or lab-grown ones better? Which diamonds are more sustainable? And which ones have a greater value over time? Questions that, presumably, will continue to be topical even in the coming years. Because especially in China and India, diamond factories created with sophisticated machines and at ever lower prices have multiplied. Furthermore, those who produce and sell synthetic or laboratory diamonds can argue that these gems are completely identical to natural ones, at least in terms of chemical composition. So who is right?

Natural diamond producers are concerned about the spread of jewelry made with lab-created stones. For this reason, the Natural Diamond Council, an association that brings together companies such as De Beers Group, Dominion Diamonds, Lucara Diamond, Petra Diamonds, RZM Murowa and Rio Tinto, has decided to explain its reasons. And to dispel some myths that accompany laboratory diamonds. These are answers, from the point of view of mining companies, which above all contest the idea that synthetic diamonds are green, friends of the environment. Even if it cannot be ignored that De Beers has been selling synthetic diamonds for some years through the Lightbox Jewelry brand…
Let’s see what the arguments of the Natural Diamond Council are.

Are lab-grown diamonds the same as natural ones?
In fact, explains the Natural Diamond Council, diamonds created in the laboratory can be distinguished from natural diamonds through the use of professional verification tools. Lab grown diamonds are produced on a large scale in a few weeks, while natural ones are billions of years old, and have specific characteristics and patterns linked to their growth system (there are two methods for creating synthetic diamonds).

Are lab-grown diamonds sustainable?
According to the Natural Diamond Council, lab-grown diamonds replicate the natural process of creating diamonds, which requires a considerable amount of electricity, mainly from the national grid. More than 60% of lab-grown diamonds are produced in China and India, where 63% and 74% of electricity grids, respectively, are coal-fired. Furthermore, the production of diamonds in the laboratory can require very high temperatures approaching 20% of the solar surface temperature.

Does natural diamonds mean they are a limited natural resource?
Formation takes place over millions, sometimes billions of years, and occurs in limited areas of the earth’s mantle, under extreme temperatures and pressures. Global recovery of natural diamonds peaked in 2005, then declined by 30% over the past 16 years.

Have lab-created diamonds depreciated in recent years?
From 2016 to 2023, the average price of a 1.5-carat lab-created diamond fell by more than 74%, the Natural Diamond Council insists. Conversely, although the prices of natural diamonds have fluctuated over the past 35 years, on average they have increased by 3% per year.

Is mining natural diamonds ethically sustainable?
Thanks to the Kimberley Process, promoted by the United Nations and the World Trade Organization, the trade in rough diamonds, diamond producers add, is regulated to ensure that it is conflict-free. The Responsible Jewelery Council (RJC) ensures responsible sourcing through third-party verified certifications. And brands, retailers and jewelers are increasingly implementing ethical sourcing protocols and policies to ensure transparency in their supply chains.

Does mining for natural diamonds harm the environment?
According to the Natural Diamond Council, natural diamonds help protect biodiversity over an area the size of the cities of New York, Chicago, Washington D.C. and Las Vegas combined. De Beers Group, for example, is working with Kelp Blue to study the potential of algae to store carbon while improving marine health. Diamond Route is a network created by the De Beers Group to protect threatened natural habitats in South Africa and Botswana.

Are natural diamonds harmful to the countries where they are mined?
The natural diamond industry, producers say, supports the livelihoods of 10 million people worldwide. Up to 80% of the rough diamond’s value remains in local communities in the form of local purchases, employment benefits, social programs, infrastructure investments, taxes, royalties and dividends paid by the industry to their respective governments. For NDC members, 85% of all procurement is local. And in Canada, the natural diamond industry contributes 24% of total GDP in the Northwestern Territories, where $17 billion went to businesses (NWT) and $7.5 billion to Indigenously Owned Businesses (NWT).

For those who have sometimes felt like Cinderella, unjustly kept on the sidelines, but also for those who simply love the fairy tale character, who promises revenge on injustices, Pandora offers new charms. Also in this case the pendants are produced under license, the result of the agreement between the Danish giant and the Californian cinema giant. The subject is, in fact, the fairy tale of Cinderella, which helps to commemorate the group’s one hundred years: the birthday is set for October 16, 2023. In this series, the Cinderella cartoon is remembered with a pumpkin and a magical carriage.

But not only that, there is also Minnie wearing gold shoes. She is not part of the fairy tale, but of the Diney world yes. But the novelty also consists in the fact that each charm is made with a diamond created in the laboratory. The use of synthetic stones, which have the same chemical composition as natural ones, is one of Pandora’s most recent innovations. The Enchanted Carriage, for example, is in silver, hand-finished and characterized by a swirl motif with openwork workmanship. It is offered in a limited edition. The stem and the door are in 14-karat gold, the window is decorated with a diamond created in the laboratory. The inscription Disney 100 is engraved on the back of the carriage. Price: 169 euros.

The hidden gems of the Italian province: the story of Quercia Gioielli ♦ ︎

Not all the jewelers are born in the center of Paris, London or New York. There are also those who create and sell jewelry from a corner of the province, in this case Varese (northern Italy). Unlike many other jewelers, however, Quercia has chosen to offer rings, earrings and necklaces of own production and a good level.

Gold and diamonds are used next to stones like kunzite, aquamarine or peridot.

Everything is born, according to the story that presents Quercia Gioielli, from the passion for the jewelry of the founder, Mauro Quercia. A passion so powerful as to convince the future jeweler to move to Valenza Po, where he attended the Benvenuto Cellini Art Institute and specializes at the Igi, the Italian Gemological Institute.
After the studies necessary for the profession, in 1998 Mauro Quercia began his career dealing with selection, cutting, and trade in diamonds. And at the age of 21, he opened a business for the sale of diamonds and wholesale jewelery. This is where the journey that definitively transformed it into a jeweler begins. The experience in the selection of the stones, in fact, is clearly visible in the classic-shaped jewels, which use colored stones with remarkable carats.

Anello in oro bianco e diamanti della collezione Amalfi

Amalfi, a small Italian city overlooking the sea of the Gulf of Salerno, surrounded by spectacular cliffs. In the 1920s and 1930s, Amalfi was a popular tourist destination for the British upper class and aristocracy. But it has retained its charm, in Italy and abroad, as suggested by the Amalfi collection signed by the German high-end jewelery house Stenzhorn. Landscapes, flavours, suggestions of the ancient maritime republic (between about 839 and 1200) were the source of inspiration for the collection.

Orecchini pendenti in oro bianco e diamanti della collezione Amalfi

The collection consists of necklaces, rings and earrings. All Stenzhorn jewels are made from precious rubies, sapphires and emeralds to sparkling diamonds. The shapes are sinuous and elongated, with a geometry that recalls marquise-cut diamonds, as if they were eyes. But also like the leaves of the lemon trees, which are found in Amalfi. The diamonds set, however, are brilliant cut.

We invite you to take a journey with us along the winding coastal roads of the Amalfi Coast and discover the hidden azure bays and colorful villages. With Amalfi, clients can feel the beauty of nature, the harmony, lightness and inner peace that this region reflects.

The best-known Indian company specializing in diamonds, as well as high-end jewels, is P Hirani. Established in 1981 in Mumbai, P Hirani is a family-run business now owned by Jigar Hirani, while Darshit Hirani is the director. Specifying that the Indian company deals with trading diamonds, however, is not enough. It must be added that they are mostly special diamonds, the colored ones, the most sought after. The so-called fancy diamonds are the house specialty. Precisely this ability to procure and resell loose diamonds or mounted on prestigious jewels has translated into P Hirani’s key to success.

With the warm season temperatures rise, we return to the sea. And, to stay on the subject, those who love high jewelery can admire the new Marea (tide) range by Gismondi 1754. On the other hand, the Maison is based in Genoa, a seafaring city and its managing director, Massimo Gismondi, loves the sea, so much so that together with Marea he launched the Vela collection. The jewels of the Marea line are top of the range. The highlight is the bracelet in white gold, diamonds and tanzanites. The ideal connection with the concept of tide is immediately clear, with the gems that recall the waves, while the diamond embroidery symbolizes the foam that forms with the refracting of the water on the shore.

From Milan to New York, passing through Piazza Italia. A journey that Antonini, the historic Milanese brand, undertakes to broaden the horizon of the market. For this reason, the company has signed an agreement with Piazza Italia, a company based in the American city which aims to create networks for the distribution of Italian products in the States. Indeed, the American market is already a market of primary importance for the jewels designed by Sergio Antonini, creative director of the Maison. Piazza Italia is proposed as a platform for companies. For example with events, such as the one scheduled from 14 to 16 March, in which the jewelery brand will also participate.

I strongly believe in this project, which will allow Antonini to have an office and a permanent showcase in New York in the beautiful spaces of Piazza Italia on Madison Avenue and a privileged channel of dialogue with interlocutors who are looking for the best made in Italy.
Diego Nardin, CEO of Antonini Milano

Furthermore, Antonini has decided to take the ethically correct path with the choice of a supplier of diamonds that do not come from war zones and to use packaging with certified recyclable material and coated with natural varnish for its jewels to water.

Turn your husband (or dog) into a diamond

Published on February 27, 2023

news/Diamanti

How about turning your dead dog or cat into a diamond? What if wuould be your husband or wife to leave you? A company proposes, for all of them, to keep the precious memory of the companions of many years: transform them into jewels. The idea, unsurprisingly, was born in the USA, where years ago a company decided to inaugurate the business of transforming deceased relatives, or domestic animals, into synthetic diamonds. The company is called LifeGem and is based in Chicago. Its activity consists in transforming the cremated remains into wearable gems, transforming the carbon contained in the ashes into (macabre) artificial diamonds. The cost depends on how many carats you want to get from the ashes. It starts at around $ 2,000 to go up to almost $ 20,000. Prices are lower for animals.

An operation that, they point out with discretion, has often been adopted for human beings: the idea of slipping the mother-in-law on the finger, in fact, for some women might sound like an attractive revenge. “Once captured, the carbon is heated to extremely high temperatures in particular conditions. In removing the ash, the process eliminates the carbon from the former house dog and with the help of our technology turns it into a diamond,” they explain to LifeGem . The service was launched in 2002. Since then customers can choose between gems of different colors, cuts, and select the setting for a pendant or a ring.

Mind you, it’s not a cheap souvenir. But, it seems, over six thousand persons have already asked to transform their dears, and bodies of cats, dogs, rabbits, horses and even an armadillo, into expensive trinkets. Like Katie Pilon, from Boston, who now wears her Meowy, a beloved cat who has been transformed into a beautiful blue blue diamond.

In truth, the company’s practices have been questioned, and some have questioned the seriousness of LifeGem. Rejected objections: “Kenneth Poeppelmeier, professor of chemistry at Northwestern University, has argued that there is no reason why the process should not work, and Avrum Blumberg, professor of chemistry at DePaul University in Chicago, admitted that it is possible to do a high quality diamond from the carbon contained in a cremated human being, “supporters retort.

Diamante sintetico dopo il taglio e la lucidatura

However, it is impossible to distinguish the origin of synthetic diamonds which, therefore, could have originated from ordinary graphite instead of from the remains of the pet. But, basically, it doesn’t matter: what better memory than being associated with a diamond, which is forever?
