Classic, twinned, deep golden color describes this calcite from the Elmwood Mine in Tennessee perfectly! The slightly football shaped crystal is doubly terminated but one side is a very complex termination with many smaller points. Gemmy tips allow for demonstration of the double refraction qualities of calcite, and, bonus – it is slightly fluorescent orange under longwave ultraviolet light. While in overall great shape for an older piece, it does show some slight scuffing on tips and top, though they are not very noticeable unless one is looking closely. Photo by IFM.

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.
