A Guide to Tourmaline
Tourmalines come in a wide variety of vibrant colours. Tourmaline has one of the widest colour spectrums of any gemstone, occurring in various shades of nearly every hue. The name tourmaline is derived from the Sinhalese 'turmali' which translates to 'mixed parcel' or 'stone with mixed colours'. Often referred to as "the Chameleon gem", not just because of its multitude of colours, but also because of its historic reputation to be confused with other gemstones.
What makes the colour of a tourmaline so mesmerising is its pleochroic characteristic. Pleochroic means that its apparent colour can change depending on the angle from which the gem is viewed.
A tourmaline's chemical composition directly influences its physical properties and is responsible for the colour of the gem. Tourmalines comprise a group of closely related mineral species that share the same crystal structure but have different chemical and physical properties. They share elements silicon, aluminium, and boron, but contain a complex mixture of other elements such as sodium, lithium, calcium, magnesium, manganese, iron, chromium, vanadium, fluorine, and sometimes copper.
Tourmaline is a 7 to 7.5 on the Moh's hardness scale, which is why it is a popular choice for jewellery, other than its rich colours.
