| Comments: | First reported by Shepard (1842) as euclase forming "thin, transparent, yellowish-white tabular crystals, lining cavities in a silvery white mica, and sometimes imbedded in a dark purple fluor" in the topaz veins. Later retracted and confirmed to be diaspore by Shepard (1851) and Dana (1851): H=7-7.5, SG=3.29, alumina 84.9%, water 15.1% and described as "thin or 6-sided tables flattened parallel to the shorter diagonal". May be more common than reported because who has really looked? |
