TQ64N0: A novelty for Tucson 2009. An excellent group both for its size and for the crystal size. The crystals are octahedrons with slight curvatures of faces and edges. They have very good luster and reddish reflections especially vivid under a strong light. The sample is from a recent find (July and August of 2008) at a Russian locality practically unknown until now.
This specimen was photographed for the ‘what’s new at Tucson 2009’ section of the magazine ‘Mineralien Welt’ and appears on page 7 of number 3/2009
