Description

This very beautiful old fluorite specimen was obtained 1938 and comes with a beautiful old label.

Like many labels of this era, especially for exported specimens the locality is"Cumberland" - there can be a high degree of certainty that the piece originated from Boltsburn mine.

Wonderful lustrous and gemmy fluorite crytals up to 33 mm across with pale brown siderite roses and calcite crysals (covering the complete backside).

Very good display specimen.
