Austinite is a fairly rare, yet much coveted collection mineral. It forms in the oxidation zone of zinc ore deposits and was named after Austin Flint Rogers (1877-1957) an American mineralogist at Stanford University. The acicular (needle-like) or bladed crystals of the mineral are infrequently large, thus it is exceptional rare to discover a crystal large enough to produce a stone of the present size. Worthy of attention by the most serious collector, this triangular-cut stone exhibits a very beautiful lime or celadon green color and is notable for its translucency and, in particular, its near-adamantine luster.
Weighing approximately 16.34 carats and measuring 16.5 x 8.5mm
