    Diamonds

    A precious stone consisting of a clear and colourless crystalline form of pure carbon, the hardest naturally occurring substance.

    Diamonds occur in some igneous rock formations (kimberlite) and alluvial deposits. They are typically octahedral in shape but can be cut in many ways to enhance the internal reflection and refraction of light, producing jewels of sparkling brilliance. Diamonds are also used in cutting tools and abrasives
