Platinum rings are very popular because of their beautiful atmosphere. However, there are some fake platinum rings on the market, including K gold rings and silver rings. So I suggest you go to a regular jewelry store to buy a platinum ring.
Distinguish the authenticity of a platinum ring, mainly by looking at the color, weight, hardness, logo, fire detection to judge.
Extension: Does the platinum ring have a certificate?
It is understood that platinum rings generally have no certificates. Under normal circumstances, only inlaid and jadeite jewels can be certified, but platinum diamond rings may be certified. In addition, if you go to a regular jewelry store to buy a platinum ring, they will generally issue a formal quality guarantee and a unified invoice.
Extension: Detailed Method of Identifying Genuine and False Platinum Rings
Many people like platinum rings, but some friends don't know how to tell the true and false platinum rings. There are some silver rings and K platinum rings similar to ordinary platinum rings on the market. So how do platinum rings tell the truth from the false?
1, look at the color
Although platinum, k-platinum and silver are all white, there are still some differences when we look closely: the color of platinum we see with the naked eye is gray or silvery white, while the color of silver is white; The color of K platinum is white with yellow, but after many things are finished, a layer of white will be plated on the surface of K platinum, so the color we see is also white.
Step 2 look at the weight
Platinum, k platinum and silver have different densities. For rings of the same size, platinum is slightly heavier, white 18K gold is lighter, and silver is lighter.
3. Measure hardness
The hardness of platinum ring is 4-4.5 Mohs, which is harder than the texture of gold and silver, so we can identify the ring by testing the hardness with special instruments. If the ring is real in the hardness range of 4-4.5, it is likely to be a fake platinum ring if it is less than or beyond this range.
4. Look at this sign
Nowadays, there are composition marks on jewelry in general. A real platinum ring will see the sign of "Pt" on the inner wall. Silver is S, while K- platinum usually has a numerical band K. In addition, besides "pt", the imprint of platinum ring also includes Pt900, Pt950 and Pt990, which represent the purity of platinum.
5, fire test
The real platinum ring is not afraid of fire, that is, it burns at high temperature, and after cooling, it is still the original luster and color; Silver will turn wet red or black red after burning, and the color of K platinum will turn black immediately after burning. This method can directly identify the true and false, but it will do harm to the ring, so be careful.
