Calcite

A parallel pair of double terminated scalenohedral Calcite crystals, each pierced and held together by a horizontal plate of likely Calcite, forms a quite unique specimen from the Dal'negorsk mining district in the Far-Eastern Region of Russia.  The two scalenohedral crystals measure 4.1 and 5.4 cm respectively and are a translucent light smoky grey.  Some faces are coated thinly, yet opaquely, with a mid to dark crust of Calcite, of clay-like appearance.  The semi-transparent plate which joins the two crystal is probably Calcite, but could be Cerussite or Baryte, but requires confirmation.  An interesting and unusual Calcite from Dal'negorsk.
