Kosnarite (extremely rare) (named for Rich Kosnar) (ex Rich Kosnar Collection)

Item Description

Kosnarite is potassium, zirconium phosphate which was named after mineral dealer and collector Richard Kosnar in 1994. The type locality for this material is Mt. Mica, Maine, and the crystals at that find barely approached 1 mm in diameter. A few years ago, Luiz Menezes made a discovery of what are the finest crystallized Kosnarite specimens in existence with crystals up to 4 mm (which is a quantum leap in size)! This is a specimen from that find featuring sharp, lustrous, whitish color, pseudo-cubic (trigonal) crystals with minor Muscovite on white Albite matrix. If you look closely, you'll see a small truncated face on each "cube" of Kosnarite on this specimen, which is actually a pinacoid or a "c" face as these crystals are trigonal and not isometric as they might appear. The quality on this specimen is as good as Kosnarite gets from any locality in the world. Based on the size of crystals, it will more than likely end up being a great bargain for one of you lucky bidders. This piece is from Rich Kosnar's personal collection.
