Tourmaline is derived from the Sinhalese word Turamali meaning 'stone with mixed colours' or 'mixed parcel' probably with reference to particoloured and multicoloured stones. Those that have two colours (particoloured) and three or more colours (multicoloured). For example, Watermelon Tourmaline crystals may be pink at one end and green at the other, or pink in the middle of the crystal and green on the outside.
Tourmaline also occurs in single colours of all variations, often with excellent saturation. It has good durability and is a very popular gemstone for jewellery making. The stone shown above is a deep pink variety.
