Calcite with Sphalerite, Fluorite

Unknown Owner
This is a spectacular large grouping of glassy double terminated calcite crystals with minor fluorite and sphalerite. Somewhat colorless in the center to amber colored terminations, this is in really fine condition. Said to have been collected in the 1970s by mine geologist Rob Austin. In super condition all around.

Calcite
Regional guide
Calcite from Elmwood Mine, USA
Elmwood Mine calcite is one of the great modern classics of American mineral collecting: honey, champagne, amber and cognac scalenohedra, often doubly terminated and twinned into sculptural “diamond” forms, set against black-brown sphalerite, purple fluorite, ivory barite, or gray carbonate matrix. The best crystals have a warm internal glow rather than merely surface color, with transparent terminations, bright vitreous luster, and enough size to dominate a cabinet. A fine Elmwood calcite does not look like generic calcite from a carbonate vein; it has a locality signature that experienced collectors recognize at a glance.
