Called the “King of Metals”, platinum is a very heavy (nearly twice the weight of gold), silver-white metal that is very ductile. Although it is a soft metal, platinum is not easily scratched, never tarnishes, and is very strong and durable. It is the strongest precious metal used in jewelry, and has good resistance to corrosion and chemicals.
Platinum is also the only precious metal used in fine jewellery that is up to 95 percent pure. Small amounts of iridium and ruthenium are commonly added to it, to give it a harder, stronger alloy that retains the advantages of pure platinum.
Platinum’s subtle beauty and its tendency to not add colour of its own, enhances a diamond’s natural brilliance and fire, making it an excellent metal for diamond jewellery settings. It does not change shape or wear away so precious stones are held firmly and securely.
Because of its purity, platinum is naturally hypoallergenic, a plus for people with sensitive skin or allergies to certain metals.
Today, platinum is more valuable than gold. Although it is used in many industrial applications, including the automotive industry, platinum jewellery consistently commands higher prices because of its rarity.
