A diamond has a hardness of 10, and is therefore the hardest known substance. They are often used in drilling and grinding materials. Diamonds have a octahedra crystal. They have adamantine luster, making them highly desired. Only about 1/5 of all diamonds can be cut into gemstones for use in jewlery-making. Diamonds are found in many colors, including, clear, pale yellow, blue, green, pink, and black. When diamonds are heated to 900*C they turn to CO2 and go into the atmostphere.
