Natural crystal rough identification method

Natural crystal rough identification method:

1. Specific gravity: The weight is too light, it must be fake. This way, glass, plastic, pressed particles and other imitation products can be excluded, but now there are more crystals on the market, and the weight is almost the same as that of natural crystal. The method is not easy to find true and false.

2, refractive index: Most people look at the crystal like lighting, so can not judge the true and false of the crystal can only see the level of crystal, because the crystal has a high refractive index. We can put the crystal in a darker place, the natural crystal color will be very bright, the color of the crystal will be dim, lack of pan-feel, only a slight brightness. You can compare it with natural white crystal and glass and feel it.

3, color difference: natural crystal has color difference, a piece of natural crystal can not be uniform in each part of the color, such as Huang Jing, the market's natural citrine is very rare.

4, water: natural citrine can be discerned in the water, the natural citrine in the water its color is not uniform, usually a piece of color radiating to the whole piece of crystal is yellow, the crystal is absolutely uniform color.
