Crystal is a transparent, crystalline quartz crystal intact. Crystal belongs to the class of crystals in the huge "family" of quartz. The chemical component is silica, and the chemical formula is SiO 2 , which may contain trace amounts of impurities such as iron , manganese , magnesium , aluminum , and titanium . It is a trigonal system. The crystal is a hexagonal column and a rhombohedron or a hexagonal double cone. The cylinder has a horizontal crystal grain. The aggregate is often a crystal cluster. The crystal is mostly colorless and transparent. The impurities may be purple, yellow, pink, brown or gray. , black and other colors. Good transparency, glossy glass surface, and shiny grease. The refractive index is 1.544-1.533, the birefringence is 0.008, and the dispersion is 0.013. Purple crystal has dichroism. Hardness 7, density 2.66 g/cm3. Shell-shaped fracture. It has piezoelectricity. According to color, inclusion and process characteristics, it can be divided into: crystal, amethyst, citrine, smoky quartz, rose crystal, black crystal, crystal and twin crystal, water crystal, star crystal, cat's eye crystal and sand crystal. Crystal evaluation and purchase. The value of crystal gemstones is evaluated by color, transparency, weight and clarity. The process requires crystals to be colorless or brightly colored, with high transparency, no cracks, and a crystal diameter of more than 3 cm. Consider the above two aspects when purchasing. Except for the slightly higher value of natural amethyst, the others are low-grade gemstones. The color of amethyst is unstable. It is easy to fade when exposed to high temperature and long-term exposure. Avoid high temperature and exposure when wearing and storing. New Product Laser Cutting Machine C Series for metal tube
