    Raw diamonds are randomly shaped rock crystals that may have bits of rock attached and internal flaws and bits of carbon. These are studied to find the clearest areas and then these areas are cut from the less than desirable flawed, included (containing spots of carbon or other forein material) areas. the clean pieces are then studied to see what the best way of cutting them (common shapes include pearshape, emerald-cut, marquis, round, oval, etc.) will be to minimize waste.

    • Actually, the raw diamonds are not randomly shaped. The shape of the crystal is determined by the arrangement of the atoms. Diamonds usually have quite regular shapes.

    • Actually, if you've ever sorted through hundreds of raw diamonds, despite the general crystalline structure, the most accurate way of describing what lays before you is, in fact, random. Some of the pieces are broken, worn and/or attached to other material.
