To identify any crystal, we usually use the methods of naked eye observation and manual test. Eye view is to look at the permeability, content and color of the crystal.

The more transparent the crystal, the higher its value. Inclusions refer to ice cracks and cotton wool. Naturally occurring crystals are inevitable, unless they are the best crystals, which are rare in the market. Glossy, the brighter the color, the higher the gloss and the higher the value.

Try it with your hands. Rock crystal will feel cold when he tries it by hand, and will not rise with the increase of body temperature. Non-natural crystals generally use vitreous body. Try it by hand and the temperature will come soon.

I hope my answer can help you. Thank you for reading.
