I bought this piece on one of my ten trips to Dal'negorsk in the 1990's. It formed in a pocket filled with palygorskite ("mountain leather"). It is a perfect floater, decorated with a few small bipyramidal quartz crystals. Some faces are lustrous black, while others are covered with a super fine dust of quartz. It measures 4 x 1.8 x 1.5 cm. These double terminated ilvaites are a rarity...
