Closer look at the Platinum metal
Platinum is a metal that was discovered in South America in 1735. It is a very dense metal, with a density of 21.45 g/cm3, but also very rare, which makes it a precious metal. It is malleable and ductile, hence its use in jewellery. Platinum resists corrosion, its natural greyish-white and brilliant colour never tarnishes in the air.
Platinum is often found in Copper or Nickel ores. Sometimes it is found in the form of ingots or nuggets.
Platinum is used in jewellery, but also in the automotive industry, petrochemical industry, medical devices and dentistry.
Platinum and jewellery
Platinum is far too malleable to make a 100% pure jewellery. Therefore, it is always alloyed with other metals. The most commonly used alloys are Platinum/Copper (95%, 5%), Platinum/Cobalt (95%, 5%) and Platinum/Iridium (90%, 10%). But there are also other alloys such as Ruthenium, Palladium, Gallium, etc.
Platinum jewellery has the particularity of being naturally shiny, hypoallergenic and resistant to wear and tear. For added security, Platinum is the ideal metal to support precious stones on jewellery, especially diamonds. Nevertheless, being a very rare metal (30 times rarer than gold), platinum jewellery is expensive. In France, they can be recognized by the dog-headed punch.
