Kosnarite is Potassium, Zirconium Phosphate and was named after 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. This piece doesn't have crystal up to 4 mm, but it does feature sharp, lustrous, cream color, pseudo-cubic (trigonal) crystals on a group of gemmy Quartz crystals. If you look under magnification, 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.
