Description

A really marvellous specimen of Diaspore var Zultanite - first you may think that there are just 2 crystals - but in fact there are three! On the right hand side there are 2 parallel crystals, one behind the other. The largest crystal to the left hand side is between the 2 others. And please look at the dimension - 29mm; this is really fantastic for Diaspore. The crystals are flawless like glass. They are razor sharp terminated and highly lustrous - a perfect, well formed twinned group in finest quality.
