Platinum (abbreviated as Pt) is a naturally pure white precious metal. Platinum does not belong to the same category as gold; it is a rarer precious metal than gold. Platinum is 35 times rarer than gold. Due to its extremely high density and twice the hardness of gold, its weight is also correspondingly higher. The properties of platinum are the same as those of gold: high stability, strong corrosion resistance, no oxidation, and high ductility.
Pure platinum is very soft. When making platinum jewelry, Pt950 is commonly used in the market, which is 95% pure platinum and contains 5% other metals. Due to the extremely high purity of platinum and its ability to maintain a constant color over time, many people choose it as a wedding ring. Common platinum jewelry is mainly silver-white in color, while platinum jewelry with electro-black processing is becoming increasingly popular in the market, giving platinum a style different from the traditional single color.
The most direct way to identify platinum is to look for the unique platinum mark on the inner surface of the jewelry - platinum or Pt. Every piece of platinum jewelry must have the unique platinum mark engraved on the back: platinum (platinum) or Pt, and after the mark there is a fraction representing the purity (content of platinum) of the platinum, such as platinum (platinum) or Pt950, Pt990 (full platinum). It is like the identity card of platinum, providing a guarantee of platinum quality.
