? Platinum diamond ring is a ring set with diamonds and platinum as a ring support. The pure white color makes it a symbol of nobility, and it also represents the pure love between lovers. Through the unique personality design, people feel the sweetness of lovers. Platinum diamond ring is beautiful and fashionable. There are also many jewelry brands selling platinum diamond rings in the market, but some are imitation platinum diamond rings mixed with other materials. Consumers should learn some identification methods to judge the authenticity of platinum diamond rings.
The first comparative method Some merchants in the market will use silver to dope platinum diamond rings, but they sell them at a high price. Platinum is a natural gray-white precious metal, which has high hardness and is not easy to bend, while silver is silvery white, delicate and round in texture, softer than platinum, and easy to bend with a little force.
The second identification method The simplest and most direct way to identify a platinum diamond ring is to look at the imprint on the ring. Usually, each ring has a component seal, "pt" means platinum and "S" means silver. If the ring is engraved with pt950, pt990, pt900 and pt850, it is a real platinum diamond ring. When buying a ring, consumers must pay attention to whether there are these marks on the ring, because some businesses will sell platinum as platinum.
In order to mislead consumers, many merchants sometimes deliberately blur the seal on the outer box of the ring. At this time, consumers can use the specific gravity method to identify. The specific gravity of platinum diamond ring is 2 1.4, and that of silver diamond ring is 10.49. A ring with the same volume is twice as heavy as silver.
The fourth burning method Sometimes the platinum diamond ring that consumers buy cannot be judged to be pure white gold because of its light weight. At this time, the burning method can be used. The color of platinum diamond ring remains by the lake after high temperature burning, while the surface of silver will turn wet red or black red after high temperature burning, and some will even turn black. However, there are certain risk factors in this identification method, and it is not recommended for consumers to use it frequently.
