What is the difference between synthetic sapphire and natural?
Synthetic gemstones similar to sapphire are synthetic sapphire, synthetic spinel, and cobalt-containing blue glass. Synthetic sapphire, which is very different from the jewels that people usually understand, natural sapphire, is generally used in the manufacture of watch mirrors. It is an anti-wear material with both tungsten-titanium and high-tech ceramics. Although these materials are resistant to abrasion, they do not withstand strong impacts, and some materials with the same or higher hardness (eg, grindstone, sandpaper, nails, granite, concrete walls and floors) may Scratch the surface of these materials.
Sapphire glass is a generic name for corundum gemstones in addition to red rubies in corundum gemstones. The main component is alumina (Al2O3). Sapphire glass is a synthetic sapphire that can easily and inexpensively produce gem-quality sapphire in the laboratory, with the same chemical composition and physical properties as natural sapphire.
So Is the synthetic sapphire a glass? Made of pure alumina at high temperatures, very hard and highly transparent. Chemically speaking, synthetic sapphire is no different from natural crystal. Because it has no other elements added, it is colorless and transparent. The original synthetic sapphire is cut into discs by a diamond tool and then polished into a mirror. This may also be one of the reasons for the higher cost of sapphire crystals, as these processing tools are also costly. Many construction and decoration materials also use silicon-carbon compounds, such as artificial stone, etc., so you must know that friction with these places will leave scratches on the sapphire crystal.
Sapphire is a synthetic material that combines the advantages of plastic glass and ore glass. It has a very high density and a hardness of 9 degrees, which is second only to diamond hardness of 10 degrees. It is not easy to scratch and has high transparency. The characteristic is that even in the case of impact, the glass will only crack, and the whole piece will not be broken. The sapphire glass is resistant to abrasion and scratches. However, the shortcomings of synthetic gemstones wholesale sapphire are its advantages and fragile. Therefore, it is not appropriate to use bumps, heavy pressures, heavy falls, etc. in use.
