New year PT Platinum gift ring for lover.

Platinum (Pt for short) is a naturally pure white precious metal. Platinum does not belong to the category of gold; it is a rarer precious metal than gold. Platinum is 35 times rarer than gold. Due to its high density and twice the hardness of gold, its weight is correspondingly higher. Like gold, platinum has high stability, strong corrosion resistance, does not oxidize, and is also a highly malleable metal. 
Pure platinum is very soft. When making platinum jewelry, Pt950, which is 95% pure platinum and 5% other metals, is more commonly used in the market. Due to its extremely high purity and the ability to maintain its luster over time, many people choose it for wedding rings. Common platinum jewelry is mainly silver-white, while platinum jewelry with electro-blackening technology 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 exclusive mark of platinum on the inner side of the jewelry - platinum or Pt. Every platinum jewelry must be engraved with the exclusive mark of platinum on the back: platinum or Pt, followed by the thousandth fraction indicating the purity of platinum (platinum content), such as platinum or Pt950, Pt990 (pure platinum). It is like the ID card of platinum, providing a guarantee of platinum quality.
