FLUORITE

Often referred to as 'the most colorful mineral in the world', Fluorite is an attractive stone found in a wide range of colours, ranging from pink, purple, magenta, blue, yellow, green, red, brown and white, as well as colourless and multi-coloured.

Originally known as Fluorspar, Fluorite’s low hardness makes it more of a collector’s stone than a gemstone for jewellery purposes.

The term fluorescence is derived from Fluorite, which can be brightly fluorescent in ultraviolet light.

 

 

Colour palette: Fluorite spans the full spectrum of colours - blue, green, yellow, colourless, brown, pink, black, and purple, with pastel versions also possible.

Bi-colour and multi-coloured Fluorite stones also occur, with some having four or five different colour zones or bands. There is also a rare colour-change Fluorite that shifts from blue to purple, depending on the lighting.

Fluorite's most famous and popular colour is a rich purple, which rivals that of Amethyst. The deeply coloured blue, green and yellow varieties of Fluorite are also popular. The colourless variety, while not as popular, is rare, making them sought-after by collectors. The rarer colours of pink, reddish orange (rose) and even black can be very attractive and in demand.

Fluorescent colours of Fluorite include yellow, green, red, white and purple, with blue the most typical.

Blue John is a banded purple and white or purple and yellow variety of Fluorite found in Derbyshire, England.

Chlorophane is a thermoluminescent variety of fluorite that emits a bright green to blue-green light when heated.

Fluorspar is now primarily the term for the industrial and chemical form of Fluorite. 

Sources: Fluorite is very common and can be found worldwide, but key sources are Canada, China, England, France, India, Mexico, Morocco, Namibia, Russia, South Africa, Spain, Switzerland and the USA.

More information about Fluorite: Fluorite is neither a designated Birthstone nor a Wedding Anniversary gemstone; it is, though, said to enhance intuition, creativity, concentration and a sense of order.

Similar gemstones: Fluorite’s colour variation means it can resemble many gemstones, but in particular deep purple Fluorite can closely resemble Amethyst.
