There are many small Pyromorphite crystals on this thumbnail specimen, and although they are rather heavily intergrown, their hexagonal prismatic form is quite visible and very good. It is difficult to assess the number of crystals on the specimen, as many of them are intergrown into "parallel associations", so that some of them appear to be both single crystals and multiple crystals that are intergrown parallel and symmetrical to each other. The largest individual crystal on the piece has dimensions of 0.5 x 0.2 x 0.2" (1.3 x 0.5 x 0.5 cm), and has a pale orange brown coloration that is different from the yellow-green color of most of the crystals. A few of them show the presence of both colors. They all show a bright, nearly adamantine luster, and are cloudy and translucent. There is only a very small amount of limonite/goethite host rock present, and the piece is generally in very good condition, though there are a few crystals that are obviously broken and incomplete.
