The stamping .950 or 950 refers to the platinum content on a piece of jewelry or other white metal item. This typically means the article is 95% platinum and 5% alloy (cobalt-palladium-ruthenium). The metal should not be magnetic and if tested by a jeweler, it can be heated with a torch without flux and when cooled should not show oxidation. It holds a polish well but is tedious to polish as compared to gold. It is also much more acid resistant than gold. The stampings .90, 90/10, .900, .95, .950, 95/5 all usually refer to platinum content with exceptions of .900 silver for coinage and pocketwatch cases.the many people who made jewellery firstt invented in the 1bc
