 Artificial crystal and natural crystal both contain the chemical composition of silicon dioxide, and high-purity silicon dioxide is known as "crystal". Natural crystal is a transparent quartz crystal, with hexagonal columnar crystallization. It has a very high hardness and extremely strong reflection. Pure crystal is a colorless transparent crystal, and almost no impurities can be found in natural crystal. Most natural crystals contain bubbles and impurities, and the crystals are mixed. Artificial crystal is made from raw quartz sand through a series of processes, refined, and then cut with precise technology and polished without flaws. The crystal is pure and transparent, making up for the deficiencies of natural crystal. Artificial crystal added metal elements such as lead can enhance the light refraction, showing the nobility of crystal. Due to the complex process of artificial crystal, the technique is high, and some of them are even more expensive than natural crystal. Ultraviolet light can pass through artificial crystal and natural crystal, but ordinary glass cannot.
