Esquire #1 Claim, Rush Creek, Fresno County, California, U.S.A.
This small hand specimen consists of a crystalline piece of Sanbornite. There is a consisderable amount of fresh breakage on the piece, but most of this is in the form of a large cleavage surface that constitutes one side of the flat specimen. It shows no definite visual crystal form, but has the classic crystalline tendencies of Sanbornite, including an almost micaceous cleavage. Its color is pale green, it has a pearly, almost micaceous luster, and is generally translucent, though some areas show impressive clarity. There is a thin crust of a dull, white material on a few of the edges that is moderately rust-stained, but no actual base rock is present.
