According to the national standard, precious metal ornaments should be marked with the origin, manufacturer, material and content, and products without marks are unqualified products. Platinum, also known as platinum, is a natural white precious metal with a purity of 85%. Pt is the symbol of platinum, usually with the purity symbol of PT900. PT950 or PT990. PT950 is suitable for necklaces, 95% platinum PT900 is suitable for ring holders, and 90% platinum 18K has good hardness and ductility, but the gold price of brand stores such as Lukfook Jewelry, which I have worn for a long time, is 3 13 today, but this gold price is different for each gold store, and the price does not mean that they will sell as much as they bid. If it is not a brand store, the general gold shop can bargain. It's not true now. Brand gold price should be around 290, platinum should be around 450. When you say platinum, you should mean palladium. That should be around 180. Go to the gold shop and ask how much is gold, platinum and palladium? But the average gold shop has a price tag. You can also ask if the price can be discounted. Generally speaking, if you bargain, it will be 20-30 cheaper than their marked price.
