Large, intact, amber-colored twinned crystal stuck on a half-ball made of small crystals of white barite, with a smaller twinned calcite crystal (7.2 cm) in the form of a bowtie at the base of the large crystal. The amber color is due to the presence of greenockite (cadmium sulfide).

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.
