This rather dense hand specimen consists of countless intergrown Diopside crystals that make up the bulk of the piece. Most of them are broken, as the specimen appears to have been broken out of a larger piece of the same material. There are some monoclinic prismatic crystals that show no damage, though, and these have reasonably good form, though they are somewhat warped and incomplete due to the intense intergrowth. They still have well-defined edges and smooth faces that show a pearly luster. Their color is a moderately pale forest-green, and they are all translucent; some could conceivably be transparent, but they are so heavily internally fractured that any clarity is destroyed. Any large hollows in between the crystals are filled with a pale blue calcite, and there are patches of a heavily worn, cream-colored mineral in places, but I cannot identify it.
