Tourmaline

The Weird and the Wonderful

Tourmaline is one of the more scientifically interesting minerals and, as a gemstone, surpasses all others with its range of color. Gemstone quality examples include rubellite, indicolite, dravite, achroite, watermelon tourmaline, and schorl.

The name comes from the Singhalese word turamali, meaning ‘gem pebbles’, and as they are resistant to weathering, they often accumulate in gravel deposits.

Emerald-green is very rare and until the 18th century was often confused with emerald.

Most dramatic examples are ‘watermelon’ tourmalines which, when sliced across the crystal show a pink centre surrounded by green, or pink at one end and green at the other.

History in a Nutshell

A pink tourmaline cabochon has been discovered set in a gold ring of Nordic origin, dating from around 1000AD.
