What stone is amethyst?
How to distinguish natural amethyst personally
1, specific gravity: light weight must be fake, so that imitations such as glass, plastic and pressed particles can be excluded. However, there are many crystals on the market now, the weight of which is similar to that of rock crystal, and it is not easy to find them by hand.
2, refractive index: most people like to look at the crystal under the lamp, so it is impossible to judge whether the crystal is true or false, only the grade of the crystal, because the refractive index of the crystal is very high. We can put the crystal in a dark place. The color of the rock crystal will be very bright, and the color of the crystal will be dim, lacking the sense of "spirit" and only slightly bright. You can use natural white crystal and glass to compare and feel it.
3. Price: There is a similarity between crystal cultivation and natural gem-grade crystal, that is, the crystal is extremely transparent, with almost no stone particles, but the price is quite different. Usually, crystal training bracelets will be cut into sections. Crystal is transparent, but the price is generally not too high. However, if it is really a natural gem, the price must be above 100 yuan, depending on the size of the crystal.
4. Color difference: Crystal has color difference, so every part of a crystal can't have a uniform color, such as topaz, which is rare in the market. Natural topaz can be identified by putting it in water. Natural topaz is uneven in color in water. Usually one color radiates to the whole crystal, which is yellow, so the crystal color is absolutely uniform.
5, others: I feel cold, and there are basically no fake stone crystals; Crystal stone will feel greasy when touched by hand, while synthetic crystal or glass will feel cool.
6. Inclusions: If there are inclusions, there will be no fakes, so it is absolutely safe to buy crystals with inclusions such as hair crystals and ghosts, because forging such things is both expensive and laborious, and the effect is easy to see through.
7. Generally speaking, there will be cotton or ice cracks in rock crystals, while there may be bubbles in synthetic crystals or glass.
