Platinum is a natural white precious metal, expressed by Pt, usually silver-gray. Platinum has stable chemical properties and is not corroded by ordinary acids and bases except aqua regia. Pure platinum is relatively soft, and the addition of metals such as ruthenium, rhodium and palladium will increase its hardness. This is a more valuable metal than gold. Its content is marked with PT900 or PT950. Please recognize this mark when you buy it. In addition, jewelry made of platinum is tough and reliable even if the processing technology is fine, and the diamonds embedded in it are difficult to fall off easily. In addition, the white luster of platinum is natural and remains unchanged for a long time, while the color of platinum is not natural and may fade after a long time.

There is something wrong with platinum. Platinum is actually a common name for platinum, but Chinese people have many misunderstandings about it. In this way, platinum, palladium and 18K platinum are called platinum, especially 18K platinum. The full name of platinum should actually be "platinum", which means platinum, that is, k gold. Platinum is actually just an alloy, which is made of gold and other white metals. Its code name is WG (Platinum), which means Platinum. White gold jewelry is often expressed as "18K platinum" or "14K platinum". Just because this alloy is white, it is called platinum.
