Identification of crystal cup:

1. Look: in the formation process of natural crystal, there are always some impurities affected by the environment. When looking at the sun, you can see light, even and small transverse lines or catkins. However, most of the fake crystals are melted by residual crystal slag and glass slag, which are polished, colored and imitated, without even stripes and catkins.

2. Tongue licking: even on the dog days in summer, licking the natural crystal surface with your tongue can make you feel cold and cool. Fake crystal, no cool feeling.

3. Light: the natural crystal is placed vertically in the sunlight. No matter from which angle, it can give out beautiful luster. False crystal can't.

4. Hardness: the natural crystal has a large hardness, and it will not leave traces when it is gently scratched on the ornament with crushed stone; if there are traces left, it is a fake crystal.

5. Check with polarizer: under the polarizer, the natural crystal has four light and four dark changes when rotating 360 degrees, and the false crystal has no changes.

6. Check with dichroism: Natural Amethyst has dichroism, while pseudocrystal has no dichroism.

7. Check with a magnifying glass: check with a ten times magnifying glass under the transmitted light, and the bubble that can be found can be basically identified as a pseudocrystal.

8. Check with hair silk: put crystal on a hair silk. If the human eye can see the double shadow of hair silk through the crystal, it is natural crystal, mainly because the crystal has birefringence.

9 test with thermal conductivity meter: adjust the thermal conductivity meter to green 4 grid to test the gemstone. The natural crystal can rise to yellow 2 grid, while the false crystal does not rise. When the area is large, it will rise to yellow 1 grid.
