This thumbnail specimen appears to consist of a single Sulfur interpenetration twin. It is in very good condition, showing light damage in one area, and has well-defined but disseminated orthorhombic bipyramidal form- aberrant growing conditions have caused several inconsistencies in structure, and I think at least one instance of twinning. The crystal has the normal bright yellow color and a bright pearly luster, and is transparent but cloudy. There is no base or host material present.
