This hand specimen consists of an Adamite crust that likely lined part of a hollow in the limonite host rock. The crust is made up of scores of Adamite crystals that are heavily intergrown and nearly impossible to study as individuals. Their orthorhombic form is difficult to study due to their intergrowth, but appears to be somewhat rounded and warped. All have a pale yellow-green coloration and the standard adamantine luster, and are translucent and cloudy.
