Gemstone of the WeekWatermelon Tourmaline


Tourmaline is the birthstone for October and can be given as a gift for an eighth wedding anniversary. It develops in one colour or sometimes a mix of colours and there are seven varieties:

Rubellite (red)
Indicolite (blue)
Chrome (intense green)
Bi-color (two or more colours )
Canary (yellow)
Paraiba (blue/green)
Cat's Eye (variety of colours)
Colour-change (changes from green in the daylight to red in false light)
Watermelon (posesses a green skin, white rind and a pink inner)

The word Toumailine means stone of mixed colours or mixed parcel and this derives from the Sri Lankian word "tourmali". Legend has it that a stone travelled along a rainbow and gathered all the rainbow's colours and turned into tourmaline. This is apparently why it is found in a rainbow spectrum of colours.

The watermelon variety of this gemstone is believed to help people attract love as well as its supposed ability to encourage calmness by resolving guilt, conflict and confusion in the mind making it the ideal gemstone to help aid the greiving process.

Watermelon tourmaline can be found in South Africa, Brazil, Mozambique, Madagascar and Sri Lanka. It is produced 100% naturally and the watermelon variety is unique in the gemstone world due to its display of three colours.

You can find faux watermelon tourmaline which is when quartz or topaz is coated using the CVD method, in the same process used to create mystic quartz.

Tourmaline is a collection of minerals but high quality versions of this gemstone are derived from pegmatite and have deposit inclusions which are visible using the naked eye. Inclusions in tourmaline include, needles, fractures and liquid-filled healed fractures.
