EM63T0: Zoisite (variety tanzanite) with Prehnite

A crystal with very well defined faces and edges, transparent, very bright and with a doubly terminated crystal. The color is especially intense and, due to some details, we believe it is natural, not induced by heating. The "fresh" appearance of related Prehnite crystal, with some white areas that must change color when heated, and the grayish shades at the bottom of the piece, that must also turned to blue-violet, are reasons why we offer this sample as natural, not heated.
