Cabinet specimen with large pockets of bluish green sheaf-like crystal bundles in radial sprays to 3mm. Within these pockets are 2-6mm Calcite crystals some of which are waterclear. Some of the Aurichalcite sprays are completely engulfed by clear Calcite to the point at which it terminates atop of the Aurichalcite termination - and it's really cool. One of the photos has a little tiny sprays no more than 0.75mm of I think Hemimorphite.
