1, specific gravity test method
There is a liquid on the market to measure the specific gravity of precious stones. The public can put the diamond of the wedding diamond ring into the diamond specific gravity liquid, and the diamond will sink. A diamond-like gem floating on a specific gravity liquid is definitely not a diamond.
2, the naked eye recognition method
The luster of a diamond is a secret that can reveal its true and false identity. After polishing, the real diamond fire color is strong, and the brilliance emitted by those imitations with high refractive index appears stiff and dull. Put the diamond in a white glass and fill it with water. If the light gets dim, it's a fake diamond.
3. Lipophilic method
Regarding how to choose a wedding ring, we must be able to correctly identify the authenticity of diamonds. Drop a small drop of water on the diamond table. It is true if the water drops swell for a long time, but it is false if they disperse quickly. Because diamonds are lipophilic and hydrophobic. Or put a little oil on the surface of the diamond and rub it with your thumb, which will make your thumb feel sticky and not easy to slide, while fake diamonds will make your thumb feel very slippery.
4. Wipe test
Rub the diamond back and forth several times on fine sandpaper. If there are scratches on the surface, it is a fake diamond; if there are no scratches, it is a real diamond.
5, white paper marking test
Draw a black line on white paper and put the diamond table on this line. If you can't see the line, it means that the diamond is real, and if you can see it, it is fake.

Maintenance of rings:
1, diamond is oleophilic, and it is easy to get oil stains and stains, which weakens the luster and fire effect of diamond, so don't wear diamond ornaments to cook or wash clothes in the kitchen to avoid the ring colliding with other objects.
2. Keep diamonds away from high-temperature oxidants such as bleach and disinfectant. It will corrode part of the crystal face of the diamond in a weak direction, resulting in artificial pits and fading of the inlaid part.
3. Diamond is the hardest substance in nature, but it is also brittle. Try not to put the diamond ornaments together, or they will hurt each other.
