All About Platinum




“Do you prefer gold or platinum?”. It is one of the classic questions that usually hear who goes by the jeweler to buy a ring, in particular for the engagement or marriage. Who is not an expert you end up choosing the least expensive metal: gold. But to know the characteristics of what is the most rare and noble material, platinum, could lead to making a different choice.
Features. The name platinum is derived from the Spanish word platina, which is literally translated into “little silver.” It’s very rare. And so it is also much more expensive than gold. It comes together with nickel and copper minerals, mainly in South Africa, where it is concentrated 80% of world production. Platinum is one of less alterable metals: has outstanding corrosion resistance, even at high temperatures, and is therefore considered a noble metal.
Platinum and jewelry. Platinum is used in jewelry for its lasting and elegance. It is soft, pliable and easy to work, but it is also strong and durable. For this, for example, it is very appreciated in jewelry to containing precious stones: the jaws platinum are more secure than those in gold. Also, the color goes well with the purity of diamonds. It’s often used in alloys with other metals, such as iridium, osmium, palladium, rhodium and ruthenium, but in this case should be reported. If you buy a platinum jewel beware that has the symbol ‘Plat’: means that platinum is a purity of 95%.
History. Platinum was already known by the ancient Egyptians: historians have established that a priestess commissioned a craftsman platinum hieroglyphics on her sarcophagus. And today, after 2500, the designs are perfectly intact. Even King Louis XVI (end of 1700) loved the platinum jewelry. And some of the most famous diamonds in the world were placed in a platinum structure, such as the Hope diamond.
