With the advancement of science and technology, more and more synthetic materials are used in industry. synthetic sapphire,The rarity and high price of natural gemstones have also prompted synthetic techniques to be used in gemstone synthesis.
Made of pure aluminium oxide at high temperatures, it is very hard and highly transparent. Chemically speaking, there is no difference between synthetic sapphire and natural crystal. Because no other elements are added, it is colorless and transparent. Raw synthetic sapphire is cut into discs with diamond tools and polished into crystal. This may also be one of the reasons for the higher cost of sapphire crystals, as these machining tools are also expensive. Silicon carbide is also used in many building decoration materials, such as artificial stone, so you should know that friction with these places will leave scratches on the sapphire crystal.
