This piece features several, brownish-orange, lustrous, translucent, scheelite crystals, to 1.6 cm across, which have crystallized in and among acicular, glassy, colorless quartz crystals to 2.0 cm in length. 6.6 x 5.2 x 4.1 cm
A unique example of aegerine made so dramatic by the presence of this sharp, floater shard of quartz! It IS a floater, terminated all around. The aegerine itself is superb on its own merit, too! 10.5 x 6.6 x 2.9 cm
Aesthetic rose quartzes are just really difficult to obtain. This one is really distinctive in that the crystals of rose quartz are arranged in a pretty ridge atop a matrix of colorless quartz. 8.3 x 6.2 x 4.2 cm
Two crossed, chisel-terminated ilvaite crystals, one an unsually big and fat one, both covered with sparkly quartz crystals but retaining their euhedral form! This truly special ilvaite specimen was mined ten years ago in Dalnegorsk. I have not seen one like it. 6.3 x 5.5 x 4.5 cm
An unusually aesthetic example of the superb smoky quartz that comes from the Ural Mountains in Russia. There is a large crystal here rising above a long, slender, doubly-terminated one – both glowing and gemmy. A smoky of this quality from Switzerland, New Mexico, or even Brazil, would cost a lot more. The Russian pieces don't get the pricing respect they deserve, to my mind. 9.8 x 9.6 x 7.1 cm
Bournonite 3.5-cm crystal perched beautifully on a matrix of gemmy quartz crystals. 6.6 x 5.8 x 2.7 cm
Frosty, sparkling barite crystals have grown atop a bed of gemmy quartz crystals. The largest barite is on inspection actually two distinct barite crystals that have intergrown, of different forms and colors: one golden, the other a frosty-quartz-coated trapezoid like the other barites. Very unusual and pretty material from a new find! The complexity is amazing. 9.7 x 8.3 x 6.5 cm
A very sharp scepter specimen of amethyst from Las Vigas just perfectly situated! 5.3 x 4.7 x 4.2 cm
An elegantly pretty starburst of gemmy amethyst crystals, with a smaller one near it, on a carefully-trimmed matrix of sparkly little clear ones. Classic Las Vigas material! 6.0 x 5.1 x 4.2 cm
A superb example of prized old material from the Sunnyside Mine: balls of pink rhodo amongst and covered with sparkly quartz. You can see a couple of tiny pyrites as well. Gorgeous! 6 x 3.5 x 2.1 cm
Sphalerites and chalcopyrites in combination are a classic from the old Creede locality, but during exploration of the 5-level in the old Commodore mine in 2002/2003, a small find was made of these crystals, along with minor galenas, in association with small, pretty amethyst crystals! This is the largest of four specimens from this exciting Colorado find which we saw with the man who collected them, in Tucson! (Report on the find is in the current issue of the Mineralogical Record) 7.6 x 7.4 x 6.7 cm
Sphalerites are classics from the old Creede locality, but during exploration of the 5-level in the old Commodore Mine in 2002/2003, a small find was made of sphalerites, chalcopyrites and galenas in association with small, pretty amethyst crystals! The sphalerites on this specimen are actually IRIDESCENT, and the little blooms of lavender amethyst are aesthetically sprinkled on their faces. We believe this to be one of the finest miniatures recovered. 4 x 3 x 2.2 cm
Sphalerites are classics from the old Creede locality, but during exploration of the 5-level in the old Commodore Mine in 2002/2003, a small find was made of sphalerites, chalcopyrites and galenas in association with small, pretty amethyst crystals! The sphalerites on this specimen are wonderfully-formed and very sharp, to 1.5 cm, with some small iridescent crystals between the golden/green larger ones. The little blooms of lavender amethyst add a beautiful accent! We believe this to be one of the finest miniatures recovered. 4.5 x 4 x 3 cm
Sphalerites are classics from the old Creede locality, but during exploration of the 5-level in the old Commodore Mine in 2002/2003, a small find was made of sphalerites, chalcopyrites and galenas in association with small, pretty amethyst crystals! This large, sharp sphalerite compound crystal has a wonderfully architectural form, with multiple parallel triangular flashing faces. The little blooms of lavender amethyst add a beautiful accent! 3 x 3 x 2.5 cm
Yeah, yeah, I know, it's "JUST" an Arkansas quartz. But at their best, there's hardly any competition for them out there. This specimen, from the collection of Marty Zinn, just has the most graceful, slender, elegant and water-clear crystals you could ask for. It is certainly NOT the familiar slab of stumpy crystals sold by the ton in Arkansas. Super ones like this deserve a place in fine collections. IN PERSON, THE CRYSTALS ARE MUCH BETTER - ABSOLUTELY WATER-CLEAR! Just hard to photograph due to reflections. 8 x 7 x 5.3 cm
