Item Description

This complex alumosilicate is one of the more obscure members of the Cancrinite group, especially in fine quality specimens. Typcially Afghanite crystals, no matter how saturated the color may be, are opaque. This specimen hosts a 1.4 cm rarely seen, somewhat gemmy, rather sharp, euhedral crystal of Afghanite of a lovely Sapphire blue color jutting out of a massive golden-white Calcite matrix. The termination is in great shape, and the crystal is aesthetically flaring out of the matrix. The crystal is certainly sharp for the species as, and the gemminess makes it a worthwhile smaller sized display specimen of this well known material.
