Mineral Specimen #3377 Hexagonite (variety of Tremolite)
Balmat-Edwards Zinc District, St Lawrence County, New York, USA
This specimen is composed of a mass of purple colored Tremolite crystals. The largest crystals are gemmy and have the best color. Hexagonite was originally considered a distinct mineral and afterwards considered a hexagonal 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).
The specimen is in good condition although the vast majority of the crystals are not terminated.
14 x 7.6 x 6.1 cm
