This thumbnail consists mostly of Leadhillite by weight that is in moderately good condition, showing considerable damage. Though crystalline tendencies are evident, any actual crystals are incomplete or have been broken. There is some massive material, also. All has a bright blue-green color and a pearly to waxy luster, though the massive material has a duller, greener color and a brighter luster. Several small, malformed or incomplete hydrocerrusite crystals accompany the Leadhillite, but no host rock is present.
