A small crust of Strengite rests on the rusty iron-bearing base of this specimen. The crust is in fair condition, as it shows considerable damage, but this damage allows one to see its radial, fibrous form. Where intact, it shows a botryoidal habit that has a very dull, almost silky luster. Its color is a pale grayish pink, though its inner material appears to be much lighter. The crust is accompanied by a few random orbs of kidwellite, a related sulfide. It would appear, however, that the kidwellite only makes up a thin skin that covers each orb, and that their cores are made up of much darker-colored rockbridgeite. The base appears to be made up of hematite and shows visible weathering.
