An old-time, showy and excellent Santa Eulalia combination specimen of lustrous pyrrhotite crystals with a nice patina, nestled in a field of tinted quartz crystals on massive sulfide matrix. Specimens of this quality came out in the 1960s or 70s. The bit of periphery damage is certainly not detracting to this fine piece. 6.3 x 5.9 x 3.8 cm
This is a very rare California specimen with a fine pedigree: from the collection of the legendary Fred Pough. The back of the old label shows him to have acquired it 40 years ago for $25 - not a small amount for a thumbnail specimen back then (what''s that, maybe $250 now?), especially considering these are infinitely harder to obtain today. Anyway: it is a perfect CALIFORNIA Japan-law quartz twin, richly included (with chlorite?) giving it pretty green color. A real prize for some lucky thumbnail collector. 1.2 x 1.0 x 0.3 cm
Sparkly stalactites of quartz sticking out in all directions, on a cast of quartz that formed around the original matrix. A very pretty specimen from a small recent find in Morocco 7.6 x 6.2 x 5.8 cm
This is not only large, but one of the PRETTIEST specimens we have seen from this find of about a year ago in China. What is unique about this one is the incredible quality of the quartz crystals - they look like the best Alpine or Arkansas quartz, just gemmy as could be, and with an elongated form that is uncommon for this find. As such, they provide a wonderful setting for the deep green epidote crystals. 16.8 x 13.5 x 8.9 cm
Bright leaves of gold aesthetically set in milky quartz matrix from a VERY UNCOMMON Canadian locality - St. Johns in Newfoundland. These pieces were collected in the 1970s. 2.7 x 1.3 x 1.0 cm
An AESTHETIC, solid cluster of gemmy and glassy, green uvite crystals with a couple of quartz crystals from the early 1990s find at the famous Brumado Mine of Brazil. Very few uvites have come from Brumado since then. Ol dKen Roberts specimen 5.7 x 4.6 x 2.5 cm
A showy and excellent cluster of intergrown, lustrous, flattened, rose-red rhodochrosite rhombs accented by two quartz crystals from the recent finds at the Daye Mine in China. Rhodos are just starting to trickle out of the Daye Mine and this is a fine, representative piece, even with the broken tips of the quartz crystals. new find! 3.5 x 2.8 x 1.7 cm
An AESTHETIC and pristine plate of gemmy, orange spessartine garnets and transparent to translucent, smoky quartz crystals to 2.3 cm on matrix. Some of the smoky faces are preferentially frosted. The back has been sawed to enhance display. 9.8 x 8.1 x 3.3 cm
A SUPERB and DRAMATIC Indian specimen of a LARGE, golden-yellow fluorite ball with a very glassy, striated, tan calcite rhomb jauntily attached to one side on a bed of quartz crystals. This is one of the most outstanding Mahodari Quarry fluorite combos, that I have seen. 9.1 x 7.0 x 5.5 cm
Now here is a hubnerite of a completely different style from the other one in this auction, even though it is from the same locality. This one has tall, very thin crystals sticking up in a forest off of a matrix of massive quartz with quartz crystals. Virtually all of the terminations are complete. This specimen came out of the Charlie Freed collection. 6.9 x 6.3 x 5.4 cm
This is a thin, flat, rectangular barite crystal that has been replaced by quartz, with the exterior now being covered with small, sparkly quartz crystals. It is complete all around, including the termination, except for the bottom where the crystal was removed from matrix. An old Colorado pseudomorph! 8.9 x 4.7 x 1 cm
From the Marty Lewadny collection, snowy aragonite on a combination of beta quartz crystals and conventional ones - VERY unusual! 5.6 x 4.1 x 3.2 cm
A dramatic specimen of spheres of red fluorite (tinted by hematite) on a background of dove-grey quartz. These are quite rare - we had a few of them and this one is amongst the most aesthetic, with a wonderful balance of the red fluorites on the quartz. 5.4 x 4.0 x 1.7 cm
Two gemmy pink rhombs of rhodochrosite (to 1 cm) perched on a bed of gemmy quartz crystals; the quartz crystals have a second generation of micro calcites and quartzes on them. 7.9 x 6.1 x 4.3 cm
One of several Zacatecas classics in this auction, all from different sources - this one, from the collection of Ed Ruggiero, and still with his index card, showing him to have acquired it in 1975. His card says it was sold to him as tennantite on quartz, and that he had in addition found the sphalerite and pyrite crystals. IN person they are all quite easy to see, and the presence of this snowy white quartz serves to beautifully isolated this combination of crystals. In places, you can see where crystals of one type have grown atop crystals of another - they are wonderfully mixed up on this pretty old piece! 13.9 x 10.8 x 7.8 cm
