Platinum is a real "newcomer" - it has only been processed into jewellery for a little over a hundred years.

There are finds from Egypt and South America that show that platinum has been known for a long time, but due to the high melting point it could never be processed properly. It was forged to its original state and processed together with other metals.
Through the Spaniards who got to know platinum from the Aztecs, it came to Europe for the first time in larger quantities. 
They could not do anything with the rare metal that could not be processed.
Well, with the exception of a few scoundrels counterfeiting gold coins with gold-plated platinum coins - today rather a funny idea.

For a while it was even considered to sink all platinum in the Atlantic to put an end to these scams!
There would be some divers on their way today!

So the platinum disappeared for a long time from the consciousness.
Until new methods of processing at the end of the 19th century led to the fact that platinum could finally be processed.

Platinum is a rare metal with many interesting properties:

  • it is anti-allergenic.
  • It has a very high density, so it is very heavy.
  • it has a relatively high hardness, whereby the hardness has to be distinguished between Brinell and Mohs, because often an impression of "indestructibility" of the platinum is wrongly created.
  • It has a high resistance to chemical influences.
  • The rarity of platinum, the fact that it is very expensive to process and the high density (a piece of jewellery in platinum is much heavier than, for example, gold) makes platinum jewellery relatively expensive.

Platinum is alloyed with 950/- or 500/- parts together with copper and palladium.
