Platinum is essentially different from platinum. PLATINUM, called platinum in English, is abbreviated as Pt, and only platinum can be marked with PT. Platinum can be said to be the rarest precious metal in the world, mainly produced in South Africa and Russia. And "white gold", or "k platinum", is actually k gold which is fused by gold and other white alloys, and its gold content is generally 75%, which is white due to the addition of other white metal elements. WHITEGOLD's English name is Whitegold, abbreviated as WG. Platinum cannot be marked with Pt, and platinum is not platinum. Platinum and platinum are only because of the pronunciation of Chinese. Some people read platinum as platinum, especially the older generation often confuse platinum with platinum, but it is easy to distinguish it by English pronunciation.
