TC86AL6: A novelty at Tucson 2020. Elongated Tremolite crystals, one of them clearly dominant, on a Dolomite matrix, with marked scepter growth. They have very well defined faces and edges, good terminal faces and an intense luster between crystalline and silky. It exhibits greater transparency than usual in specimens from this area and a beautiful gray-green color with bluish tints. From a recent find, the quality is also far superior to what is generally known from the St. Lawrence County area.
The crystal was reinforced, already at origin, in two spots on the prism to avoid its possible separation.
