8.2 x 7.4 x 4.4 cm. A large and magnificent tourmaline specimen on matrix from Paprok. This big, fat juicy crystal, with multiple hues of intense green, measures 3.75 cm long-ways across the termination (and is 5.75 cm tall), and it is attached to a stark white euhedral crystal of albite that shoots off the backside and upwards, providing contrast to the green termination. The tourmaline has a perfect, glassy, flat termination on top.
3.1 x 1.5 x 1.3 cm. Kosnarite is Potassium, Zirconium Phosphate and was named after the late Richard Kosnar in 1994. This is a specimen from the find at Jenipapo and features several sharp, lustrous, orange-yellow colored, pseudo-cubic (trigonal) crystals on white, translucent bladed Albite crystals. Ex. Kosnar Collection.
6.4 x 4.1 x 3.4 cm. This aquamarine crystal is actually just under 6 cm in length, and most of its bottom termination is intact and can be seen protruding from the cleavelandite at the bottom of the specimen. The crystal is very gemmy; the upper part has natural vertical striations that give it an etched look.
5 x 5 x 3.7 cm. This piece has sharp, lustrous kosnarite crystals to 3 mm perched nicely on albite matrix. Ex. Martin Zinn Collection.
7.9 x 5.3 x 1.4 cm. One of the larger clean plates of the new phosphate species, kosnarite, which came out a few years ago. Just covered with bright, lustrous crystals. Ex. Martin Zinn Collection.
10.4 x 7.3 x 4.2 cm. Though this area is known for minerals widely, it is not particularly known for albite specimens. So this is actually quite an unusual specimen and comes from a recent find by Donald Heins at this old locality. These sharp crystals have formed knobs or rosettes that give the specimen pretty 3-dimensionality.
7.2 x 6.9 x 6.8 cm. Natural internal fracturing makes these fluorite crystals look rough in the photo, but in person they have very lustrous faces. In another recessed area are crystals of smoky quartz. Both are nestled in stark white albite.
5.5 x 4.8 x 3.1 cm. A really complex combination piece, with an aquamarine shooting straight up through the crystallized albite feldpsar matrix (you can see it extend from underneath) like a fiber-optic cable of gem blue glass that transmits light from below if you shine it up. On this aquamarine is perched, as a wraparound, a spessartine garnet crystal that is pretty good on its own merits; plus the bonus that it is set up like a flag above the sharply crystallized white background. The terminated zigzag schorl at the base is a final bonus. Ex. Helmut Bruckner Collection.
8.2 x 6.8 x 6.2 cm. A superb rosette of snowy, bladed albite crystals, out of the Richard Hauck collection, from Brazil.
5.9 x 5.9 x 4.2 cm. A complete, large, uncontacted and undamaged, gemmy crystal of morganite on matrix. This light pastel-pink crystal measures 4.8 cm across, and is a beefy 2 cm thick. It is highly transparent through the center. The crystal is cupped in a perfect setting of stark white, bladed cleavelandite.
2.6 x 2.1 x 1.9 cm. Kosnarite is a Potassium, Zirconium Phosphate and was named after Richard Kosnar in 1994. This specimen features sharp, lustrous, yellow color, pseudo-cubic (trigonal) crystals 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. Ex. Richard Kosnar Collection.
6.3 x 4.8 x 3.3 cm. A fine bi-colored tourmaline crystal cluster from Stak Nala, Pakistan. The lustrous, dark tourmalines, to 5.9 cm, have striking, super-gemmy and beautiful green caps. The jackstraw tourmalines are stunningly complimented by lustrous, pearlescent cleavelandite blades. This is classic excellent, older material from the 1980s finds at Stak Nala.
2.3 x 1.5 x 1.0 cm. A superb thumbnail of a very sharp, mirror-lustre, metallic-gray anatase crystal beautifully set on contrasting, snow-white albite microcrystals from the famed Valdres Region of Norway. Ex. Gary Hansen Collection.
7.0 x 5.4 x 3.4 cm. Lustrous, brown brookite blades to 8 mm are aesthetically scattered or concentrated in a vug and are nicely complimented by lustrous, albite blades on this superb specimen from a classic and historic locale in Wales - Twll Maen Grisial, the Type Locality for brookite. Ex. Phillip Greybill Collection.
6.4 x 5.9 x 2.8 cm. An old-time New Hampshire combo specimen that came with an old J. Cilen label. One main smoky sticks up about 2 cm from the bladed albite. Ex. Richard Hauck Collection.
