This is a killer, razor-sharp, glassy, twinned calcite crystal with good golden colour. Super transparency – at several angles one can see right through this crystal. The twinning is pronounced, with prominent re-entrant faces. The calcite is perched on sphalerite.
In excellent condition. The left-hand (as in the first photo) termination has a tiny chip (as displayed, depending on your preference, it’s either at the bottom or behind on the right-hand side, and in either case not relevant) and there are a couple of small chips on one edge. Under the lights, this crystal glows. Stunning!
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 a few years ago. Most specimens were damaged and these are exceptional – the handful of high-quality specimens in this update are the result of a quest through many flats of specimens.
