Sell PlatinumPosted on: 22nd February 2012 By Anita
At Gold Smart you can sell platinum jewellery and palladium items for cash. This could be a platinum ring, necklace, bullion or item containing precious metals. Since platinum is more typical in jewellery, here are some interesting facts about this metal.
Platinum is a chemical element with the symbol Pt. At normal temperature, platinum appears in its solid form. It was discovered by the Andean people and the Spaniards came to know it in 1735 when they came to South America. It is used to manufacture electrodes and jewellery. Also, it is widely used as a catalyst in chemical reactions.
Platinum jewellery is hypoallergenic, strong, durable and resistant to stains and loss of sheen. Unlike most gold jewellery items, platinum jewellery typically contains platinum in its almost pure form.
All platinum jewellery must have a tag that shows the purity:
– 900 Pt (or 900 Plat), marked “900 Pt” or “900 Plat”, indicates that platinum is 90% pure.
– 950 Pt (or 950 Plat) / Pt (or Plat) marked “950 Plat” or simply “Plat” indicates that platinum is 95% pure.
Platinum offers a sturdy grip for diamonds and gemstones, but the strength of the metal can make re-sizing platinum rings difficult.
The Andean people discovered platinum and used as a substitute for silver. It was known by the Spanish in 1735, when the Spanish navigator, explorer and astronomer Antonio de Ulloa arrived in South America.
In 1741, platinum was taken to China. For several centuries it was used to make fake gold items, due to its similarity in density.
Some people even today get confused thinking that platinum and white gold are the same thing, but they are in fact completely different. Normally white gold jewellery is made using yellow gold and at least one white metal, usually nickel, manganese or palladium and typically a coating of rhodium to obtain the white-light effect. Therefore, white gold doesn’t have the same purity, rarity, durability and natural white colour of platinum.
