This hand specimen consists of a crust made up of intergrown, fan-shaped Hemimorphite aggregates that partly covers a goethite/limonite host rock. Most of the aggregates are very small, but one in particular is much larger than the rest, having dimensions of 0.9 x 0.5 x 0.4" (2.3 x 1.3 x 0.9 cm). Though it is also the most exposed aggregate, it is in excellent condition, showing no damage. Though the crystals therein are heavily intergrown, they appear to have very good orthorhombic bladed form. They are colorless and translucent, and have a milky-white color and a bright, vitreous luster- most of the smaller clusters, however, are noticeably transparent.
