Identification of Platinum in Platinum Diamond Necklace
In the platinum diamond necklace, the real platinum jewelry is made of metal platinum. Metallic platinum, also known as platinum, has a chemical symbol of Pt, with a specific gravity of 2 1.45 and a Mohs hardness of 4.3. Compared with platinum and gold and silver in the same volume, platinum is the heaviest and hardest. This is one of the reasons why this kind of necklace is popular. Platinum is a more valuable metal material than gold because its natural reserves are few, it is difficult to mine and its chemical properties remain unchanged.
If it is made of stainless steel or silver, it is easy to mix with the real platinum diamond necklace. The fake "platinum diamond necklace" made of stainless steel is similar to the real necklace, with gray color and bright luster. However, its white color is gray-black, bright and false, not durable and easy to wear. The silver necklace is soft and easy to wear; Light in weight, white in color, whiter than platinum, and easy to turn black when used for a long time.
There are stamps on real platinum jewelry, which is the first sign. Hot stamping mainly includes the following contents: first, the texture of jewelry, platinum jewelry has two kinds of texture, many of which are English Pt and many are Chinese "Platinum"; The second is the composition of jewelry. If there is "99" on the platinum jewelry, it means that the platinum content is 99%;
