Calcite (Twinned)

Specimen # 101303
Mineral: Calcite (Twinned)
Location: Calcite (Twinned), Elmwood Mine, Carthage, Smith Co., Tennessee, USA
Size: 8.0 x 5.9 x 3.0 cm


Detailed Description

A nice cluster of sharp, lustrous twinned calcite crystals. The crystals are a champagne hue with a hint of golden colouring towards a couple of terminations. The crystals are all twinned, but the one at the righ-hand side is beautifully, prominently twinned with pronounced re-entrant faces. In very good condition, with small cleaves at some tips – these are minor relative to the piece overall, and particularly minor when looking at it in the display case, nonetheless the specimen is priced accordingly. With nice transparency, and some internal rainbow-like colour under the lights at certain angles, this is a very attractive piece.

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.
