The calcareous base of this small cabinet specimen holds several sheaf-like Legrandite aggregates. These aggregates do not exceed 0.4" (1 cm) in length and are generally in very good condition, due to the protective nature of the host rock. All show a rather well-defined, thin monoclinic prismatic form, the standard deep-yellow color and a bright pearly luster. Though individual crystals are transparent, the aggregates are merely translucent. A crust of creamy, often rust-stained calcite or dolomite coats the limestone base beneath the Legrandites.
