Calcite

Unknown Owner
A very fine loose glassy gemmy amber colored double terminated twinned crystal grouping of calcite. From the 1970s. This is in good condition.The Elmwood Mine in Smith County, Tennessee, is a well known zinc mining locality that has been worked since the mid 20th century. The deposit consists of Mississippi Valley type mineralization in limestone, producing zinc, lead, and associated minerals. The mine is especially famous among mineral collectors for producing high quality specimens such as sphalerite, fluorite, calcite, and barite. Many specimens from Elmwood are noted for their large size, bright color, and excellent crystal form, making the locality one of the most important modern sources of fine mineral specimens in the United States.

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.
