BMR70AQ0: Very sharp Boleite crystal, with a little limonite matrix. Its very well defined faces have brilliant luster and a very deep color. The crystal is of high quality for the deposit, from which it is very rare to be able to obtain a specimen.
The label, from an important European collection, has been applied to both of the pieces into which we split the original piece, as previously the two crystals seemed a bit lost.
