How to identify crystal

1. How to identify crystal

The advancement of science and the semi-precious stones are inexhaustible. The most common examples of changing the color of a crystal with high heat are white crystal, citrine, agate, amber, and amethyst. After the artificial jewellery is flourishing, almost all of the semi-precious stones have artificial materials, and the more advanced technology is to grow crystals in the laboratory. The surface observation is completely different from the real stone. However, the artificial spar, the appearance is realistic, and in terms of energy, it is far from natural.

Really spar, warm in the cold, there is a real feeling. I personally experienced: the first test crystal wears a string of powder crystals, the crystal inside is still relatively vague, but soon there will be changes, it begins to become more and more clear and clear, the original, the crystal energy is really combined with the human body Applied. The friends around me also have the same reaction. Relatively speaking, the fake spar has no life, is weak and vain. Legend has it that wearing fake crystals can cause trouble to the body and even bad luck.

specific method:

Look: Natural crystals are often affected by environmental influences during the formation process. When viewed from the sun, you can see a faint uniformity of small horizontal stripes or catkins. The fake crystals are often smelted with crystal slag and glass slag. After polishing and coloring, there is no uniform streaks or catkins.

Tongue: Even in the hot summer days, using the tongue to rub the surface of the natural crystal, there is a cold and cool feeling. Fake crystals have no cool feeling.

Illumination: The natural crystal is placed vertically under the sun, and it can give off beautiful brilliance from any angle. Fake crystals can't.

Hardness: The hardness of the natural crystal is large. Use the gravel to gently stroke the ornament, leaving no trace; if there are streaks, it is a fake crystal. Check with polarizer: Under the polarizer, the 360 ​​degree is changed by the natural crystal, and the unchanged is the fake crystal.

Check with two colors: natural amethyst has dichroism, and fake crystal has no dichroism.

Check with a magnifying glass: Under the transmitted light with a ten-fold magnifying glass, the bubble can be found as a fake crystal.

Check with the hair: put the hair in the middle of the crystal beads. The human eye can adjust the angle from top to bottom through the crystal. You can see that the two hairs with the real hair as the middle line are double crystal, which is natural crystal. Mainly because crystal has birefringence, glass can't. This method is only suitable for transparent crystals.

4, artificial crystal, imitating the environment created by the crystal, synthesizing crystal, the same as natural crystal.

5, dyed crystal, add white crystal or inferior colored crystal color, into tea crystal, powder crystal, amethyst.

Crystal is a well-crystallized single crystal quartz. It is as clean as ice, which makes people believe that there is a hidden god. The Gypsies make it into a ball to predict the future. This is just a beautiful imagination. The chemical composition of crystal is silica, which is widely distributed in nature. Among them, the East China Sea is rich in high-quality crystal. Crystals with gemstone value are produced in volcanic rocks, pegmatites, or in caves of limestone and shale. Crystal can be used to make ring faces, necklaces, crystal balls, and can also be used to make carvings. Crystal is a low-grade gemstone. The value depends on transparency, quality, and clarity. But the price of a large crystal ball is much more expensive. In addition, the crystal is in good shape, and crystals with special inclusions, such as crystal clusters, crystals, and phantoms. Deeply loved by collectors.

Identification of pseudo-inferior crystal

The materials used for crystal are mainly glass and synthetic crystal.

Glass is isotropic and is generally black at any location under orthogonal polarization, but sometimes produces abnormal birefringence due to stress. The refractive index is usually between 1.50-1.70, and single refraction can be distinguished from crystal by accurately measuring the refractive index value. The inside of the bubble and the vortex pattern can also be seen by magnifying the observation, and the glass hand feels warm.

Synthetic crystals have the same characteristics as natural crystals, but contain less gas-liquid inclusions. Large-volume crystals may contain daughter crystal nuclei, which cannot be distinguished from natural crystals by conventional detection methods.

This is a very simple rule to follow, it is not difficult at all! Look at yourself first, are you going to pick it up? Still have to pick "good-looking?" If you want to pick a good one, we recommend that you choose the bigger the crystal, the better. Because, from the perspective of E=MC2, the energy is proportional to the mass. The higher the mass, the stronger the energy and the greater the effect. The better it is. The reason is as simple as that.

Of course, the bigger the difference is not necessarily the more expensive, we just pick a large size, heavy weight, not necessarily pick beautiful, good-looking, the more beautiful!
