Fibrous lavendar Termolite with scattered purple Hexagonite crystals. Hexagonite was formerly considered a seperate mineral but is actually a form of Tremolite. It has been shown to be pseudo-hexagonal and is actually monoclinic. The color is due to manganese. This is an older specimen from a collection from suburban Detroit and appears to have been self collected by the collector in the 1960s (there were a number of specimens of varying sizes wrapped in newspapers from 1962).
