A fine toenail composed of a lemon-yellow 1.3 cm Ettringite crystal, along with gemmy micro-Ettringites, on doubly-terminated calcite with Andradite. There are also needles of a dark mineral (hematite?) along the bottom side. The major Ettringite crystal has a well-formed hexagonal habit and excellent luster. An excellent, and very aesthetic, combination thumbnail. Ex. Charlie Key.
