First, the China gold diamond ring is true and false
The quality of a diamond ring has little to do with the brand, and the brand only represents people's trust. China Gold belongs to a well-known domestic jewelry brand. If the diamond ring is purchased from a large regular store, the credibility is relatively high. There are also some private shops under the banner of China Gold. The diamond rings sold in these stores may not be guaranteed, and they may buy fake diamond rings, so everyone must buy them from regular channels.
Second, the identification method of diamond ring
1, look at the diamond certificate
Diamond certificate is the most direct way to identify diamonds. When reading a diamond certificate, you should pay attention to whether it is an international certificate. Some are certificates issued by the brand itself. Of course, certificates are also divided into true and false. If you don't buy from the regular channels of well-known brands, and you can't identify the certificate, you'd better choose other methods.
2. Drip method
According to the principle of diamond hydrophobicity, the diamond ring was identified by water drop method. If the water drops are bulging and persist for a long time, then the diamond ring is real. However, this method is more suitable for larger diamonds, and the accuracy is not high for small diamonds.
Step 3 breathe
Breathing method, as the name implies, is to breathe into the diamond on the diamond ring and then observe the water vapor on the surface of the diamond. If the water vapor dissipates faster, then the diamond ring is real.
4, oily pen line drawing method
Oil-based stroke line method mainly uses the principle of diamond oleophilicity to draw a line on the diamond with a ballpoint pen or other oil-based pens. If the lines on the surface of a diamond are intermittent or even impossible to draw, it is false. If it is clear, it is true.
