Calcite (Twinned)

Specimen # 101308
Mineral: Calcite (Twinned)
Location: Calcite (Twinned), Elmwood Mine, Carthage, Smith Co., Tennessee, USA
Size: 5.6 x 2.6 x 2.5 cm


Detailed Description

This is a glassy, transparent twinned calcite crystal with great lustre and sharpness. Most of the crystal is a champagne colour, with faint golden hue closer to the edges. Super twinning on this one.  In excellent condition. The bottom termination (it should be supported to stand as in the first photo) is incomplete as it did not form completely, ending at the surrounding rock in the cavity. A small nick near the termination, displays towards the back and is minor relative to the specimen overall. A beautiful gemmy Elmwood calcite at a great price.

About These Elmwood Calcites

First opened in the 1970s, the Elmwood Mine (the Elmwood-Gordonsville-Cumberland mining complex) has produced some of the world’s finest calcite crystals, many of which are twinned. Over the years, the miners referred to the large orange Elmwood calcite crystals as “footballs”, and they referred to the clear gemmy calcites in this update as “jewels”. These are from a pocket found in late 2014. Most specimens were damaged and these are exceptional – the handful of high-quality specimens in this update are the result of a quest through about 50 flats of specimens.

Highly dependent upon global metal prices and given the low price of zinc, the Elmwood Mine was unfortunately closed in December, 2015. Metal price fluctuations are cyclical and this is not the first time this has happened – the Elmwood Mine has closed and reopened under new ownership in the past. For now, the mine has been placed on care and maintenance with an uncertain future ahead. Hopefully at some point in the future it may be profitable for someone to reopen it.
