Apatite
Apatite appears in a range of colours from white, yellow and green to blue and violet. In coarse non-gem quality crystals, Apatite can reach enormous sizes of up to hundreds of kilograms in mass, but the clear crystals from which gemstones are cut are always small.
Beautiful blue stones are found in the Mogok Stone Tract of Myanmar and in the gem gravels of Sri Lanka, some of which have a fibrous structure and, when cut en cabochon in the correct direction, display a ‘cat’s eye’ effect. Yellowish green crystals found in the Spanish province of Murcia have been referred to as ‘asparagus stones’ due to their peculiar colour.
Major sources of Apatite include Ajmer, Devada and Madras in India, where the crystals unearthed are often sea-green.
