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.
