Afghanite is a hexagonal aluminosilicate of sodium and calcium. The mineral is compositionally related to lazurite, but differs in crystal structure. Bariand et al. (1968) named the mineral after Afghanistan, wherein the type locality resides.

This specimen consists of a single large hexagonal crystal of afghanite, 2.5 by 1.1 cm, mostly free of matrix. These crystals occur completely frozen in marble, but are mechanically excavated. There is micro-chipping present due to the preparation method. Minor phlogopite mica is also present in the crystalline calcite, i.e. marble, matrix. This specimen could be carefully trimmed down to a fine thumbnail. Please note that the bottom of the piece has been sawn.
