Because of this pure diamond really should transmit seen light and show up as a transparent colorless crystal. colours in diamond originate from lattice defects and impurities. The diamond crystal lattice is extremely sturdy, and only atoms of nitrogen, boron, and hydrogen is usually launched into diamond during The expansion at significant concentrations (around atomic percents).
due to the fact diamond is composed of the element carbon, many people feel that it have to have formed from coal. This is still taught in read more lots of lecture rooms - but it is not real!
