Fluorite octahedron crystals of varying colours from Illinois, USA. These individual crystals are available in various sizes and have been cleaved into these octahedron shapes which is done due to the fluorite minerals points of cleavage which allows it to ‘break’ in four directions. Despite this, they still exhibit, excellent, almost gem quality clarity with very minor inclusions. Such crystals from Illinois are now difficult to come by these days as the fluorspar mines in the areas have long since ceased operations, causing supply of crystals to be exhausted. The crystals are available in various colours, chosen at random. Available in three different sizes, they come supplied individually packaged, in a polythene bag with information label. Small: Approximately 1cm in length Large: Approximately 2cm in length All measurements taken at the widest points
