Its optical transparency extends within the far infrared on the deep ultraviolet and it's got superior optical dispersion. In addition, it has large electrical resistance. it truly is chemically inert, not reacting with most corrosive substances, and it has great biological compatibility.[9]
Diamond has the highest hardness and thermal conductivity of any organic content, Houses that happen to be Utilized in key industrial purposes including reducing and sprucing tools. Also they are The explanation that diamond anvil cells can subject matter components to pressures discovered deep within the Earth.
Gem-Slash artificial silicon carbide established inside of a ring A diamond simulant can be a non-diamond substance that's used to simulate the appearance of the diamond, and may be often called diamante.
