This hand specimen consists of a cluster of several intersecting Diopside crystals that reach lengths of up to 2" (5 cm). Though many of the crystals are broken and incomplete, much of the breakage appears to be rather old, and a surprising number of crystals are intact and in very good condition. Though rather heavily intersected, most have excellent monoclinic form and a rather interesting 8-sided habit that appears quite symmetrical. Their prism faces have a bright pearly luster and odd pitting that resembles some acid-etching marks that I have seen- the crystals might be stabilized with a resin coating. All have a dull, deep forest-green coloration and are essentially opaque- this opacity is probably caused in part by intense internal fracturing. There is no host rock present.
