Why can’t platinum jewelry wear gold with gold? Why does it become yellow after wearing it for a long time? Brene is a precious metal that is naturally white. The annual mining volume of platinum is only one -twenty of gold, and a ounce of platinum needs to be refined from 10 tons of platinum ore. The domestic platinum jewelry usually contains 90%of pure platinum and is attacked on the “PT900” logo. Platinum white gloss is naturally natural, and long -term wearing will not fade. The hardness of platinum makes it the best friend of diamonds. White K gold is gold and some alloys are white. It only contains 75%of gold. Molying the squeezing of daily gold, because the pure gold is too soft, the gold is usually synthesized with other metals such as silver, copper, nickel, and zinc to increase its hardness and durability. Generally speaking, the hardness of 18K gold inlaid with jewelry is lower than that of platinum and is easy to wear. If it is worn with platinum jewelry, platinum is easily stained by gold. Causes platinum discoloration. I don’t have easy cleaning, only to get a store for special care. The gold is relatively soft and easy to deform. Avoid collision, squeezing, pulling, etc. to avoid deformation. Gold cannot be worn with platinum jewelry, otherwise, the platinum ring will become yellow. Because of the high hardness of platinum and low gold, after friction, the gold powder is dipped in the platinum surface, and the phenomenon of platinum turns yellow.
