Identification of crystal trophies:
1. Look: During the formation of natural crystals, they often contain some impurities due to environmental influences. When you look at the sun, you can see a faint uniform fine horizontal stripes or catkins. The fake crystals are mostly smelted with residual crystal slag and glass slag, polished and colored, and there are no uniform stripes and catkins.
2. Tongue licking: Even in the three volt days of summer, licking the surface of natural crystals with your tongue has a cold and cool feeling. Fake crystals have no cool feeling.
3. Illumination: The natural crystal is placed vertically under the sun, and it can give off a beautiful radiance no matter what angle it is viewed from. Fake crystals cannot.
4. Hardness: The hardness of natural crystal is high. If you rub the stone gently on the jewelry, it will not leave any traces; if there are streaks, it is fake crystal.
5. Check with a polarizer: The natural crystal is the one that has four bright and four dark changes when rotated 360 degrees under the polarizer, and the fake crystal is the one that does not change.
6. Check with two colors: natural amethyst has dichroism, fake crystal has no dichroism.
7. Check with a magnifying glass: Use a ten-fold magnifying glass to check under transmitted light. Those that can find bubbles can basically be set as fake crystals.
8. Check with hair silk: Put the crystal on a hair silk, and if the human eye can see the double shadow of the hair silk through the crystal, it is a natural crystal, mainly because the crystal has birefringence.
9 Test with thermal conductivity meter: Adjust the thermal conductivity meter to 4 green squares to test the gems. The natural crystal can rise to 2 yellow squares, while the fake crystal does not rise. When the area is large, it rises to one yellow square.
