1, the simplest identification depends on the metal mark. Regular platinum jewelry will be marked with the word "pt" according to national regulations, but the platinum content of different jewelry is also different. Will be divided into platinum, 950 platinum, 900 platinum, 850 platinum. If there is no such word, you don't have to read it. Definitely not platinum.

2. Look at the color of jewelry. Many people will confuse silver with platinum. First of all, you should know that the color of silver is white, while pure platinum is tin white, with a little gray in the white, and the color is bright, while platinum is beige, so you should distinguish from the color when you buy platinum in the second step.

3. Point-and-try method. This method is a bit complicated. You can ask the power supply to grind some powder from the corners of jewelry and put it in hydrogen peroxide when you buy it, because real platinum can be used as a catalyst to decompose hydrogen peroxide, thus releasing oxygen. Then you can see if there are any blisters. If there is, it is real platinum. If not, pay attention.

4, melting point judgment. We should know that the melting point of platinum can be as high as 1773℃, so ordinary welding guns can't directly melt platinum, but this method is difficult to realize.

5. natural judgment. You can put platinum jewelry next to the open gas stove and let it stand for a few minutes. If the jewelry turns red, the gas is ignited by heating, which proves that it is a real platinum product.

6. Find a special jewelry store for identification. If you haven't learned or don't want to damage the jewelry itself or are not sure about the difference, it is recommended to take the purchased platinum to a special jewelry store for identification, which is also the simplest and most intuitive method.
