1.3" 51ct PaleGreen/Yellow ColorChange DIASPORE Termnatd Crystal Turkey for sale

DIASPORE is a native aluminum oxide hydroxide which crystallized in the orthorhombic habit. This crystal, which comes from Selçuk, Mugla Province, Aegean Region, Turkey, is a lovely pale shade of transparent yellow-green. Diaspore crystals are hard to find, and good diaspore crystals are very highly prized. I found this piece at the Tucson Gem Rock and Mineral Show this year on the table of a Turkish mineral dealer whom I've been buying kammererite from for years. Since the mine closed decades ago, this is old material; there are no active sources for diaspore crystals, so I think this is a fine choice for any collector.
