How to identify natural crystals? Natural crystals are clear and transparent, often containing cloud-like, star-like or flocculent gas-liquid inclusions, and often have microcracks. In addition, the natural crystal is polarized, and the phenomenon of twin crystals, such as a crystal sphere, can be seen from the top to the bottom. The following small series collected a little about the identification of natural crystals, let's get to know it. How to identify natural crystals? There are mainly the following methods: Seeing: Natural crystals are often affected by environmental influences during the formation process. When viewed from the sun, you can see a faint uniformity of fine stripes or catkins. The fake crystals are often smelted with crystal slag and glass slag. After polishing and coloring, there is no uniform streaks or catkins. Tongue: Even in the hot summer days, with the tongue licking the natural surface, there is a cold and cool feeling. Fake crystals have no cool feeling. Illumination: The natural crystal is placed vertically under the sun, and it can give off beautiful brilliance from any angle. Fake crystals can't. Hardness: The hardness of the natural crystal is large. Use the gravel to gently stroke the ornament, leaving no trace; if there are streaks, it is a fake crystal. Check with polarizer: Under the polarizer, the 360 ​​degree is changed by the natural crystal, and the unchanged is the fake crystal. Check with two colors: natural amethyst has dichroism, and fake crystal has no dichroism. Check with a magnifying glass: Under the transmitted light with a ten-fold magnifying glass, the bubble can be found as a fake crystal. Check with the hair: put the crystal on a hair, the human eye can see the double shadow of the hair through the crystal, it is natural crystal, mainly because the crystal has birefringence. Use the thermal conductivity meter to detect: adjust the thermal conductivity meter to the green 4 grid test gemstone, 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. The above is the identification of natural crystals, I hope to help you. Chef Uniforms Chef Uniforms Guangzhou Hanguang Fashion Co.,Ltd , https://www.aliuniform.com
