The prominent 2 cm twinned crystal on this piece just glows when you stand this specimen up under the lights – lots of internal play of light and great transparency. This specimen actually hosts two generations of calcite crystals, as these transparent crystals are perched on darker, zoned, brownish crystals. In excellent condition, the main crystal has tiny chips in a couple of spots, hard to see without magnification. A beautiful calcite from an unusual locality!
About these Yushnoe Mine Calcites
The Yushnoe Mine is a newer mine and to date has produced virtually no fine mineral specimens. In 2015, a pocket of calcite crystals contained some beautiful twins. This was not a large or prolific find at all, and all specimens had some damage. They show excellent twinning, with the same form as the now-classic twinned yellow calcites from the Sokolovskoe Mine, Rudniy, Kazakhstan.
