Description

A gemmy emerald crystal with an intense color, disposed very aerial on a matrix with calcite and small crystals of the same mineral. It shows a developed prism, with curious growths on faces, and a terminal pinacoid showing natural corrosion forms and a small dent, which does not affect its aesthetics. Good transparence and brilliance. Good choice.
