Tourmaline is the gemmological name for an important group of gem quality minerals and thanks to its wide array of colours, Tourmaline is considered to be one of today's most versatile gemstones. 

Its rainbow of colour varieties means that most Tourmaline now has a colour-specific name, with some of the most popular being the pink-red Rubellite, the blue-green Paraiba and the pink-green Watermelon Tourmaline or bi-colour Tourmaline.

All coloured Tourmaline displays pleochroism, changing colour and colour intensity depending on the angle at which it is viewed.


Sources: Key sources of Tourmaline are Afghanistan, Pakistan, Russia, Myanmar, Sri Lanka, and the USA. However, several African countries have recently become big producers of gem Tourmaline, including Madagascar, Malawi, Mozambique, Namibia, Nigeria and Tanzania.

Similar gemstones: Tourmaline's wide range of colours mean it can be confused with many other gemstones. Green Tourmaline can resemble Emerald, Peridot, Demantoid and Tsavorite. Red Tourmaline is similar to Ruby, Spinel and Garnet. Pink Tourmaline bears a resemblance to Kunzite, Spinel, Pink Topaz, Morganite and Pink Sapphire, while Blue Tourmaline may be mistaken for Aquamarine, Blue Topaz, Sapphire and Zircon.
