The word diamond has a Greek origin
The word diamond comes from the Greek word adámas, which means “unalterable”, “untamed”, or “unbreakable”.
Diamonds are made of 100% carbon
Diamonds are pure carbon, and the carbon atoms are formed into a tetrahedron structure (think of a four faced triangle). Biologist and chemist Antoine Lavoisier first discovered that diamonds are pure carbon in 1772. He directed sun rays towards the diamond in oxygenic atmosphere and observed the production of carbon dioxide.
