Description
Several clusters of lustrous black Cassiterite crystals are aggregated over a granitic matrix, from Bunny mine at Stenalees, St. Austell, Cornwall, a mine on the southern flanks of the Hensbarrow granite boss. The individual Cassiterite crystals measure to 1.5 cm on edge and form well defined, lustrous pyramidal prisms protruding from a snowy white matrix of altered granite. Because of fractures within the Cassiterite crystals and a slightly friable matrix, the specimen has been reinforced using a low viscosity superglue which is drawn into microscopic cracks by capillary pressure. No glue is visible, giving the specimen a perfectly natural appearance. The requirement for this treatment has, however, been reflected in its reduced price.\n
Known provenanceKnowing where your specimen comes from and who owned it adds to its story and value. Good provenance helps prove it's authentic and preserves important details about its discovery.
