Kosnarite on Albite (ex Rich Kosnar Collection)

Item Description

Kosnarite is Potassium, Zirconium Phosphate and was named after the late Richard Kosnar in 1994. The type locality for this material is Mt. Mica, Maine and the crystals from this find where no more than 1 mm across. A few years ago, Luiz Menezes made a discovery of what are the finest crystallized Kosnarite specimens in existence with crystals over 3 mm (which is a quantum leap in size for the species). This is a specimen from the find at Jenipapo and features several excellent, sharp, lustrous, yellow colored, pseudo-cubic (trigonal) crystals on white Albite matrix. If you look closely, you'll see a small truncated face on one corner of 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 crystals on this specimen measure up to 2 mm, which is rather large for the specie. Additionally, the quality is as good as Kosnarite gets from any locality in the world. Don't miss out on this piece, they are almost impossible to obtain in today's market.
