The word diamond derives from the Greek word “adamas,” which means invincible or indestructible. It is modified form of carbon. Under the immense heat and pressure far below the earth’s surface, the carbon atoms bond in a unique way that results in diamonds’ beautiful and rare crystalline structure.
