RAINBOW FLUORITE SLAB
Thick Rainbow Fluorite Slab. Fluorite is one of our most popular minerals, loved by young and old. It is rare to get a piece with so many colours altogether. The front and back are polished. A great piece to add colour to the collection, and quite rare to find as this type of fluorite is uncommon and used for carvings or jewellery when it is available. Aesthetically outstanding when back lit by natural sun or electric light. My photos don’t do this piece justice, it was a dark overcast day.
De’an Mine, Jiangxi, China.

Named in 1797 by Carlo Antonio Galeani Napione from the Latin, fluere = “to flow” (for its use as a flux). The term fluorescence is derived from fluorite, which will often markedly exhibit this effect. The element fluorine also derives its name from fluorite, a major source for the element. Fluorite is a mineral with a veritable bouquet of brilliant colours, it is well known and prized for its glassy luster and rich variety of colours. The range of common colours for fluorite starting from the hallmark colour purple, then blue, green, yellow, colorless, brown, pink, black and reddish orange is amazing and is only rivaled in colour range by quartz. Intermediate pastels between the previously mentioned colours are also possible. It is easy to see why fluorite earns the reputation as “The Most Colourful Mineral in the World”.
