Natural XXL Emerald Dioptase Specimen x 1 From Tantara, Congo

A NOTE FROM NICK 
An XXL natural 33 cm long Dioptase specimen with Emerald green crystals growing over most of the surface of the dolomite matrix. It's very rare for Dioptase specimens to reach these dimensions. Between Dioptase being a fairly rare and sought after mineral (with even small pieces commanding high prices) and this one being exceptionally large, this can be considered as a museum or collectors piece.
