Natural crystal jewelry is always beautiful and beautiful. I believe that every female friend wants to have a crystal of her own. However, whether it is in the store or online, I will worry about the true and false of the crystal. If you buy fake crystals, then you won't be able to pay for it. So how do we train a pair of "eyes" that distinguish true and false crystals? Therefore, today China Jewelry Merchants Network Xiaobian integrated the identification method of crystal, summed up a few simple and effective natural crystal identification methods for your reference.
Natural crystal is a transparent quartz crystal with a hexagonal column. There are inevitably ice cracks or cotton wadding in the natural crystal, and the color of the natural crystal with color is not uniform. In addition, there is absolutely no bubble in the natural crystal. If it is, it can be judged to be glass or artificial crystal. Ice cracks, cotton wadding, uneven color and steam drums can be used to identify 90% of crystals. Most of the counterfeit crystals on the market are synthetic. They are made from quartz sand raw materials through a series of processes. They are made by fine cutting technology and absolutely flawless grinding. The crystals are pure and transparent, making up for the natural crystal. insufficient. Therefore, to identify natural crystals and artificial crystals, we can use the following methods for preliminary identification:
1, eye view method
As mentioned above, natural crystals generally have ice cracks or cotton wadding, but artificial crystals do not have this feature. Therefore, when identifying crystals, you can carefully observe the crystal under the light. If the crystal contains small or trace impurities and inclusions, it means natural crystal. If the crystal is very pure, then you need to be extra cautious. In addition, natural The cylinders of the crystal have parallel stripes, while the artificial crystals have no parallel stripes.
2, handcuffs
Natural crystal is heavier than glass. Put the crystal in your hand and rub it. If it has a heavy feeling, it is a natural crystal. If it is lighter, it may be artificial crystal.
3, considerate method
The thermal conductivity of natural crystal is better than that of artificial crystal. Therefore, when crystal is identified, the crystal can be placed on the forehead. If there is a cold feeling, it means natural crystal. Otherwise, it may be artificial crystal.
4, lighting
The natural crystal is placed under the sun, and no matter which angle it is viewed, it can give off a magnificent color, especially shining. Synthetic crystals can't achieve this effect.
5, hardness
The hardness of natural crystal is large, and it is not left with a trace of gravel on the ornament. If it leaves a trace, it means a fake crystal.
6, with hair
Because the crystal has birefringence, according to this feature, the crystal can be placed on a hair silk. If the human eye can see the double shadow of the hair through the crystal, then the crystal is a natural crystal.
7, tongue method
Even in the hot summer days, as long as you use your tongue to lick the natural crystal surface, you will feel cold and cool. Synthetic crystals have no feeling of coolness.
In addition, natural crystals can be identified by polarizers and magnifiers or thermal conductivity meters. In fact, the identification of natural crystals is very simple, as long as they are carefully observed, they can be identified.
