The'pt900' or'pt950' seen on the products of the jewelry store means that the platinum content in the jewelry is 90% and 95% respectively. 2. Rarity Platinum is 35 times rarer than gold. In the world, it can only be mined in very few places, mainly in South Africa and Russia, as well as a few areas in Zimbabwe, Canada, and South America. Every year, only 88 tons of platinum are made into jewelry, while gold has 2,700 tons. The number of platinum mines is even smaller, with a ratio of 1:10 to gold mines. 3. Durability The density and weight of platinum make it more durable than other jewelry metals. All precious metals leave scratches, and platinum is no exception.
