This astrophyllite hand specimen boasts three large sprays of the crystals on an impure calcite host. The largest crystal measures 40mm long and 4mm wide, and the clean crystals on the front of the piece have a good vitreous luster and brassy color. Examination with a loupe shows that the color picture is much more complex - each crystal is a montage of colored segments, all different shades of gold, brass, copper, or brown, put together like a stained glass window. Very pretty, and too bad that a loupe is needed to appreciate this. Where the rock is broken away, the three-dimensional nature of the crystal sprays is visible (at first glance, it looks like the crystals are all flat against the specimen). And a close examination reveals a half-dozen additional clusters, although these tend to be small and weathered (with a dull luster).
