men’s silver bracelet Characteristics of Crystal

The chemical composition of crystal is pure silica with a specific gravity of 2.66, which is very stable. Unlike other gems, which contain many other elements or contained substances, the specific gravity will be in a range. Its refractive index is 1.544~1.553. , The birefringence difference is 0.009, the dispersion rate is 0.013, and the hardness is 7, which are high-hardness gems. Many building materials use quartz bricks to emphasize its durability by using its anti-wear properties.

Crystal (quartz) is widely used in industry, mainly because the crystal has piezoelectric effect Piezoelectricity. After the crystal is pressurized, it will carry positive and negative charges at both ends and release a stable vibration frequency. This feature is used in watches and clocks. Most of the above mentioned can guarantee the long-term accuracy of the clock; many spiritual practitioners or qigong practitioners believe that the magnetic field of crystal is very strong, mostly because of this piezoelectric effect.

The classification of crystals is mainly based on the color and appearance characteristics. The crystals we generally refer to generally refer to colorless and transparent quartz. The names of other crystals refer to the crystal by color, such as amethyst, sitrien, ens. Or it can be called by external characteristics, such as sprinkled gold quartz, hair crystal, ens.

Tans, the most important exporting country of crystal in the world is also the largest origin. Brasilië, other origins include India, Sri Lanka, Madagaskar, the United States, Mexiko, Uruguay, Germany, Scotland, Switzerland, Spain, Hungary and South Africa.
