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.
