Bi-colour Tourmalines: a fantastical rainbow display in a gem

Bi-colour Tourmalines: a fantastical rainbow display in a gem

Tourmalines are nature’s one and only kaleidoscopic gemstone. They can be found in almost every tone known to man. Greens, reds, pinks, blues and purples. There’s truly an infinite array of possibilities! But arguably, the most intriguing kind of this species are the Bi-Tourmalines, or, Watermelon Tourmalines.

Multi-coloured Gems:

This special variety is a one-of-a-kind marvel of blending hues. When the variation in colour is displayed along the crystal’s length, they are classified as either bi or tri-coloured Tourmalines. However, if spotted concentrically – in the form of a pink core surrounded by a green rind, then you guessed it: this is a Watermelon Tourmaline.
