The dark green crystals to 17mm on this exceptional dioptase specimen line the inside of the large vug in the matrix.  These are deep green, lustrous crystals of dioptase, with razor sharp edges and joins, and smooth faces on most of the crystals that catch and reflect light in brilliant wet-look flashes. This piece comes from an old find at the old classic Reneville mine in Zaire. The crystals are clean and damage-free, except around the outside edges, and the specimen is really aesthetic and highly dramatic. Ex-Charles M. Noll Collection, with old labels. Noll (1922-2014) bequeathed his extensive mineral collection to his alma mater, Marquette University in Wisconsin. The University had no geology department, so it went to the Seaman Mineralogical Museum, and was later dispersed.
