When pure, the diamond is usually clear and transparent, but it is sometimes colored. In its rough state, it is commonly in the form of a roundish pebble, or of octahedral crystals. It consists of carbon, and when heated to 14 degrees Wedgewood, and exposed to a current of air, it is gradually, but completely combustible. When pure and transparent, it is said to be of the first water.2.
