Tourmaline is a crystal silicate
mineral compounded with elements such as aluminium, iron,
magnesium, sodium, lithium, or potassium.
Tourmaline, known as 'gemstone of the rainbow',
comes in a wide variety of colors. As the old Egyptian says,
tourmaline, on its long journey up from the centre of
the Earth, passed over a rainbow. In doing so, it assumed all the
colours of the rainbow. Tourmaline is a recommended semi-precious
stone for the traveler.
