Description

A very nice old time terminated blue-john fluorite specimen from the famous Old Tor Mine, Derbyshire, collected sometime in the early 1950's. Old Tor mine is one of the smaller, lesser known and much less frequently offered localities for this world famous, and much sought after, form of fluorite. 

The specimen comprises of a deep blue-purple cleaved cube with lustrous stepped faces and sharp edges. Cleaved surfaces show colour variation and banding in section. There is a little calcite to one edge. 

A good Specimen and increasingly hard to find in this condition.
