Tourmaline the rainbow gem - Discover more at Winsor Bishop

Tourmaline, renowned for its selection of colours has long been regarded the “rainbow gem.” From deep, vivid tones to the gentle wash of water colour hues this intriguing gemstone befits its Singhalese name “tura mali” translating to “stone of many shades”.

A tale of long ago explains beautifully of how the tourmaline came to be, gifted to the earth’s surface from the depths below, passing through a rainbow of colours serene.

The generosity of colours shown throughout this magnificent gemstone are a direct result of the chemical elements each stone is exposed to as it is forming under intense heat and pressure deep below the surface of the earth. As the crystal structure grows, it encompasses the chemical elements that fit most easily within its structural lattice. As these available surrounding elements are depleted, other elements are substituted and the colour of the crystal changes.

GREEN TOURMALINE

Known in the jewellery world as the beautifully accurate term “verdalite” which comprises the Latin ‘viridis’ meaning ‘green’ and the Greek suffix ‘lith’ meaning ‘stone’.

Green tourmalines can be cut in all kinds of different ways in order to fully display their stunning colour, however the cutting of a tourmaline requires incredible attention to detail to maximise the strength of the colour when viewed at the most impressive angle.

The huge responsibility of ensuring the gemstone doesn’t reflect too light or too dark is not one to be taken lightly as the green spectrum of the tourmaline has something so mysteriously tantalizing about it. The colours it contains are extremely harmonious and pleasing to the eye, the colour of nature with all its facets of individual vivacity.

Named after the state of Brazil in which they were first found buried deep within the hillside, Paraiba tourmaline was determined to have achieved this otherworldly blue hue from the presence of copper within the crystal structure and it has been widely agreed that this unique and rare gemstone has a vividness and intensity of colour unequalled by any other gem in the world.

Watermelon Tourmaline

The bi-coloured and multi-coloured zoning that is visible in the watermelon tourmaline happens when elements change in concentration or composition during the crystal structures growth. These unique gems can have coloured areas across the length of the crystal, or they can have a core of one colour and an outer edge of another colour.

Unlike any other gemstone in the world, a single tourmaline crystal can sometimes contain up to 15 different colours visible within it.

In the case of the watermelon tourmaline, pink and green crystals are found within the same stone, this occurs when the crystal structure is exposed to different minerals such as manganese and lithium during the formation process which subsequently cause the gem to change colour from a pink centre through a pale zone to the green rind. This display of banded colours resembles a delicious slice of watermelon.
