Diamonds are already adopted For most utilizes because of the materials's exceptional Actual physical traits. It's got the best thermal conductivity and the highest seem velocity. It's lower adhesion and friction, and its coefficient of thermal enlargement is extremely small.
Its optical transparency extends through the much infrared into the deep ultraviolet and it's got significant optical dispersion. Furthermore, it has superior electrical resistance. It truly is chemically inert, not reacting with most corrosive substances, and has superb biological compatibility.[nine]
The Darya-I-Nur Diamond The best high-quality as per coloration grading is totally colorless, which happens to be graded as D color diamond around the world, this means it is totally no cost from any colour.
