Crystal has eight elements, and it is easy to recognize the eight elements of true and false crystals.
1. Specific gravity: The weight is too light, it must be fake, so it can exclude glass, plastic, acrylic and other imitation products, but now there are more crystals on the market, and its weight is similar to that of natural crystal. The method is not easy to find true and false. Some special proportions are relatively large (heavier than crystal) and belong to purple lead glass.
2. Look at the crystal: there are bubbles inside, it must be glass (melted crystal). If there is a growing line, it must be cultured crystal. And there is glue and cotton, it is definitely natural crystal.
3. Look at the color: Now the smelting crystal and the artificial crystal can be added, and the color that can be added can already be faked, so if you want to distinguish between true and false, it depends on whether the purple is attached to the crystal, whether it is natural or not. Amethyst in the morning light, watching in the sunset, you will find 2 colors!
4. Price: the lowest price of smelting crystal, followed by artificial crystal, the highest is natural crystal, the natural amethyst is better, the price is about 8 yuan a gram, even better can reach 40-60 yuan a gram .
5. Feel: The hand feels cold, the natural crystal is basically the same as the cultured crystal, and the smelting crystal feels like glass.
6. Inclusions: Crystals with inner inclusions are never fake crystals, so buying crystals with crystals, ghosts, and other connotations can be absolutely assured, because forging such things is costly and laborious, and the effect is easy. Being seen through.
7. In general, natural crystals will have cotton or ice cracks, while synthetic crystals or glass may have bubbles inside, and there will be growth lines in cultured crystals.
8. Chromatic aberration: There is color difference in natural crystal. It is impossible for a piece of natural crystal to be uniform in color. For example, citrine, the natural citrine on the market is rare. Natural citrine can be discerned in water. The color of natural citrine in water is uneven. Usually, a piece of color radiates to the whole piece of crystal, which is yellow. The crystal is absolutely uniform.
