Blue John Mineral Specimens

Blue John Mineral Specimens

Blue John is a unique form of Fluorite from the Derbyshire area, particularly the area around Castleton.

It is an extremely rare form of Fluorite and is only getting rarer - a very small amount comes to the market every year.

It is usually purple, sometimes purple and yellow - and often exhibits good cubic crystals.

Our current stock includes:

• #4 - 113x111x92.7MM / 1.58KG - a quality small cabinet piece with distinct, well formed cubic crystals covering several of the faces.

• Several low quality small specimens sold as random picks. Very good budget option for collectors who want their first piece of Blue John.
