The chemical composition of artificial crystals and natural crystals is silica, and high-purity silica is called "crystal". Natural crystal is a transparent quartz crystal with hexagonal columnar crystals. It has high hardness and strong reflection. Natural crystal is a natural magnet (SIO2) with silica as its main element, also known as "transparent quartz." After tens of thousands of years of tempering through the earth, natural crystals contain huge energy waves and are effective in many fields. They are called "magical stones." The beauty of natural crystals inadvertently attracts the attention of jewelry designers, and then quickly penetrates the entire decorative field, becoming the first choice for people to decorate, watch, collect and even care. Pure crystals are colorless transparent crystals, and natural crystals without impurities are almost impossible to find. Natural crystals mostly contain bubbles, impurities, and crystals. The artificial crystal is made of raw material quartz sand, which is refined through a series of processes, and then refined by fine cutting technology and absolutely flawless grinding. The crystal is pure and transparent, making up for the deficiency of natural crystal. The addition of artificial crystals into metal elements such as lead enhances the refraction of light and reveals the nobleness of the crystal. Due to the complexity of the artificial crystal process, the craftsmanship is superb, and some prices are even more expensive than natural crystals. Ultraviolet light can pass through artificial crystals and natural crystals, while ordinary glass cannot.
