This intense green emerald is 2.3 cm long, 1.5 cm wide, and glows with color. Not only is it on matrix, or calcite matrix, but it is on crystallized calcite matrix. The calcite crystal atop is about 1 inch across. It makes a great contrast in color and crystal form to the emerald. The emerald is typical in overall hexagonal habit, but atypical in that the surface is minutely detailed, as if somebody took a scribe tool and inlaid a complex cityscape on its surface. The result of this complexity on the apparently smooth outer faces is that the emerald is much more sparkly than you would expect, with all those microfacets reflecting light.
