How to identify the authenticity of white crystal
1, inclusion
Generally speaking, rock crystals are naturally formed in the earth, and most of them have inclusions, natural ice cracks, clouds and ribbon changes. Artificial crystals are synthesized and concentrated by factories or laboratories, so the crystals produced are almost flawless. Generally, crystals with inclusions will not be forged, because the cost of forging inclusions is very expensive and laborious, and the effect is easy to see through.
2. Specific gravity
If the natural white crystal is found to be very light in weight, then this crystal is mostly fake, so that imitations such as glass, plastic and pressed particles can be excluded. However, due to the large number of cultivated crystals in the market, their weight is almost the same as that of rock crystal, so it is not easy to find the truth by hand.
3. Refractive index
Generally, we can't judge the authenticity of natural white crystal under the light, because the crystal has a high refractive index. 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 pan-spirituality, only slightly bright. You can use natural white crystal and glass to compare and feel it.
4, color difference
Crystals have chromatic aberration. It is impossible for every part of a rock crystal to have a uniform color, such as topaz. There are few natural topaz in the market. 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. However, white crystal is transparent and colorless, so it is difficult to identify white crystal from color.
The difference between true and false white crystals
Inclusions growing in rock crystals are wrongly called impurities and defects, which is the best proof that they grow in nature. Because it is naturally generated, the same crystal will have chromatic aberration, natural impurities and defects, which can be used as a method to distinguish rock crystals.
The transparency of intraocular lens is a very pale feeling, and some of them also contain regular oval flocs-the formation layer of intraocular lens. The surface luster of natural white crystal is mostly light blue, with occasional bubbles (not bubbles like glass, but natural gallbladder bubbles).
Are there many fake white crystals?
Generally, if a better crystal shop buys crystals, there are few fake white crystals, because our country produces them itself and they are not rare crystals, so it is impossible to make fakes.
Most white crystals contain ice cracks and clouds. Unless the completely transparent white crystal is small in size (directly cut and ground from the raw ore), the large completely transparent white crystal is more expensive and there are many fakes on the market, so be careful when buying it.
White crystal purchase suggestion
White crystal is the king of crystal, but its output is very small. The white crystal mentioned here is actually rootless white crystal, which was condensed after gasification after volcanic eruption 900 thousand years ago. Such white crystals are rare. Now the so-called "white crystal" on the market is mostly white, in fact, it is all kinds of variegated colors before cutting. There are white crystals and near-white crystals. In the former case, the certificate will say rootless white crystal when testing true white crystal. The latter certificate is generally written in white crystal or crystal white. At present, many counters in shopping malls are rented, so in fact, shopping malls are mixed. In order to ensure the purchase of genuine white crystal, it is recommended to obtain an appraisal certificate when purchasing.
