Snug inside a quartz crystal-lined rhyolite geode are two intergrown crystals of smoky beta quartz! 5.7 x 5.6 x 3.9 cm
A large, DRAMATIC specimen of fine, terminated ferberite crystals (to 4 cm) growing on a large quartz crystal. Though the quartz crystal is not complete, the side on the display face features dozens of flashy sub-terminations (which do not show up well in the photos but are wonderful in person). Much better in person, a real knockout! 9.2 x 7.4 x 5.4 cm
Now very rare on the market, this is a stellar miniature example of a rare habit and color of quartz found at Dalnegorsk about 4 years ago. There were very few of these fat, tapered crystals found. The color is phenomenal and unique. It is complete, although there is a white secondary coating atop portions. I have not had a good one for sale in some time 4.1 x 2 x 1.2 cm
This unusual, sculptural piece is a one-off I have not seen more of. It is a very interesting and 3-D specimen with translucent, sparkling quartz that has completely replaced the original disc-shaped calcite crystals. Interspersed among the larger crystals are thin, acicular green crystals of actinolite variety byssolite. 11.5 x 7.3 x 3.4 cm
This sharp miniature features a splayed group of crystals, undamaged, perched on Manganite matrix. The large rhodo scalenos glisten with sugary lustre because of a thin coating of microcrystalline quartz. Exceptional miniature of a rare style, collected from a small pocket in the early 1980s and unique to this time. It is very much more translucent when backlit strongly (but glows even when minimally so backlit, as shown) 3.4 x 2.5 x 2 cm
A rare old-timer, out of the noted East Coast collection of John Legro (late 1800s/early 1900s). This material is noted in books, but is seldom seen on the market. A valid specimen, with characteristic rocky matrix and the old labels, is extremely rare (in fact, this is the first i have had). 9.5 x 8.8 x 4.8 cm
Superb example of calcite from this startling new find! It is perched on some crystals of quartz ps after anhyrdite and also has small, sparkling quartz crystals as accent as well 5 x 3.5 x 2.7 cm
Another superb example of calcite from this startling new find! This one features a 5.25 cm DOUBLY-TERMINATED crysatl exquisitely perched on a plate of quartz. 6.6 x 4.3 x 2.2 cm
A large, beautiful and flashy specimen featuring sharp, bright tetrahedrites combined with equally sharp, bright & brassy chalcopyrites, in a perfect balance! Little clusters of quartz add a pleasing accent. The tetrahedrites measure up to 1.5 cm and the chalcopyrites to 2 cm. BETTER IN PERSON AND BRILIANTLY SHOWY IN A CASE! 14.2 x 12.0 x 3.3 cm
Wheatley Mine pyros are rarely available on the market. This specimen features a rich druse of pretty moss-green crystals on quartz crystals. Small crystals, but richly covered and unusually pretty overall for this classic. Under a loupe, they are bright and gemmy 9.6 x 6.5 x 3.4 cm
This is a huge, lustrous smoky quartz crystal that not only has an Alpine-like gemminess to it, but most remarkably, is a DOUBLY-TERMINATED FLOATER! It features multiple points on either end, and beautiful staggered growth around the periphery. I could only find one ding on this whole huge crystal. Very rare and just astonishing! We saw only this one monster and a few smaller ones at Tucson, and grabbed all. 13 x 8 x 6 cm
An exquisite calcite twin, transparent and standing up perfectly on the matrix, with elegant quartz crystals shooting all around and even THROUGH it. The terminations are sharp and complete as you can see. Specimen can be VERY easily trimmed (very soft matrix) to a fine miniature if you prefer. 8 x 7 x 7 cm
This is a classic example of the fairly rare phosphate, eosphorite, with unusually individualized crystal rising from crystallized rose quartz which is itself draped over a matrix of crystallized clear quartz. This combination from Brazil came out at the heyday for this locality more than 25 years ago - none of this type have been found since and they remain a highly desirable classic. The light brown eosphorite crystals, to 1.5 cm, are sprinkled liberally over the top of the specimen and stand starkly - most such specimens have much less relief to them. In addition, I really like the color contrasts. Note that the piece can be displayed vertically, as well. 8 x 6.2 x 4.1 cm
WOW - i'll let the pics speak here. Never seen anything like it, for rose quartz. Interspered among the two shades of rosy quartz are tabular blades of bright, silvery muscovite mica. Good crystallized rose quartz is almost only from Minas Gerais, Brazil. This is atypical, but in a good way! 11.2 x 6.5 x 4 cm
The rose quartz here is worth the price on its own, I think! Moreover, radiating clusters of lustrous eosphorite crystals up to .5 cm drape over the rich pink, elongated crystals of rose quartz. The silvery-brown eosphorite makes a great contrast against the rose quartz. The rose quartz crystals are unusually long, measuring over 3 cm. This is a Brazilian classic from 30 years ago. Few specimens are so richly coated as this one, or so pretty as a result. 7 x 5.6 x 3.9 cm
