Identification of crystal trophies
1. Viewing: Natural crystals are usually enriched with some impurities during the composition process. When surveying the sun, you can see a light and even fine grainy or catkin-like substance. The fake crystals are often made of inferior crystal slag and glass smelting, which are formed by polishing and coloring, without uniform stripes and catkins.
2. Tongue: Even in the hot summer days, with the tongue licking the natural crystal appearance, there is a cold and cool feeling. Fake crystals have no cool feelings。
3。 Illumination: The natural crystal is placed vertically under the sun, and no matter which viewpoint you look at, it can give off a beautiful glory。 Fake crystals can't。
4. Hardness: The natural crystal is hard, and it is cut off with the gravel on the ornament, leaving no traces; if there are streaks, it is a fake crystal.
5。 View with polarizer: Rolling 360 degrees under the polarizer has four crystals and four dark changes are natural crystals, and no changes are fake crystals。
6。 View with two colors: natural amethyst has dichroism, and fake crystal has no dichroism。
7。 Use a magnifying glass to view: Use a ten-fold magnifying glass to view under transmitted light。 The bubble can be found as a fake crystal。
8. Use the hair to view: put the crystal on a hair, the human eye can see the double shadow of the hair through the crystal, it is natural crystal, the first is because the crystal has birefringence.
9. Check with the thermal conductivity meter: adjust the thermal conductivity meter to the green 4 grid test gems, the natural crystal can rise to the yellow 2 grid, while the fake crystal does not rise, when the area is large, it rises to a yellow grid.
