A LARGE and very impressive Eastern European galena specimen, MUCH more impressive in person, in that you have a compound cluster of galena with staggere, stepped growth all along the sides, so that it just shimmers. But more than that, the galena cluster is nestled in a bed of small, translucent poker-chip calcites that wrap around its edges, which have grown atop silky quartz crystals -making this piece truly exceptional. 12.4 x 8.4 x 6.7cm
This beautiful specimen formed when gemmy calcite crystals grew in the natural pocket formed by a buried fossil clamshell. This one is almost completely composed of fine, golden crystals, with just a tiny bit of the shell left. These would be beautiful calcite crystals for any locality, but the fact that they are from Florida, a place not known for fine minerals, makes them extra special. 4.4 x 3.8 x 2.8cm
We have tried to put a large and interesting variety of Dalnegorsk calcites in this auction, side by side. This is from a new find that the Russians called "mushroom" calcites, where the crystals in this pocket grew on top of one another like mushrooms! 4.1 x 3.4 x 2.6cm
This is an intact pocket FILLED with deep pink and GEMMY crystals of the prized cobaltian variety of calcite! You do not often see a whole pocket in matrix like this - it is really striking to see these hot pink gems inside a non-descript chunk of rock! Some good quality cobaltian calcites have been coming out of Bou Azzer in limited amounts lately, and we have been grabbing all the affordable ones we can . . .but this one, in fact, came out of the Erberto Tealdi collection. 13.4 x 8.7 x 8.0cm
This large, striking Dalnegorsk specimen has a BIG (8 cm), GEMMY calcite TWINNED crystal crowning it (gemmier than the pics make it look), with wonderful luster and beautiful striations on the faces. The crystal is beautifully framed by thin sheets of snow-white feldspar. A silky scalenohedral crystal sticks out from the side of the specimen. YOu will love the symmetry of this crystal on either side of the twinning plane - it is a really unusual and beautiful large calcite twin! 13.3 x 12.4 x 12.2cm
We have a fine large Russian calcite twin in this set of auctions, so why not a Chinese one! This is a glowing, golden, lustrous crystal, complete and terminated all around, with the reentrant (twining plane) clearly visible. The crystal has a few TINY bruises (you can oil them out, we as a rule do not do this before selling things). 11.2 x 10.7 x 8.4cm
A cross of two intergrown, gemmy calcite crystals, both doubly-terminated - one, with a strange etched "stalk" at one end. 3.9 x 3.4 x 1.2cm
Irai was known for these unique calcites, and then the supply seemed to dry up. There were hardly any available at the last year''s Tucson show, and they were overpriced, so we bought none. Then, to our surprise, we found a cache of new specimens with one dealer at the small Spring Denver Show last year, and cherry-picked all the best ones, and sold them. Then they disappeared again - until finally, a contact brought us the only specimens we saw at this year''s Tucson Show, and we bought the entire lot - the good, the bad and the ugly - in order to get the good ones. This is a relatively large specimen with one big crystal lying flat on its side and others sticking up off the matrix. The matrix is very unusual in that it has purple tones from amethyst mixed with the usual copper-mineral green, adding to the attractiveness of this one. 12.6 x 12.2 x 6.6cm

We put two specimens in this auction to show the great contrast amongst these Irai specimens (note the other Irai calcite in this auction). This is the more "classic" look for Irai, with long, slender crystals. 9.7 x 6.8 x 4.4cm
There were only a few specimens from this amazing find that appeared at Tucson, with a single Russian dealer - no clue whether that was all there will ever be or not. What you have is this gorgeous sparkly pyrite of two tones, gold and copper, decorating the crystal faces. VERY unusual specimens, I have not seen their like before from anywhere! 6.2 x 4.7 x 4.0cm
Bright pink (though not quite as bright as the pics show), lustrous, shimmering crystals of pink cobaltoan calcite from recent finds in Morocco. One of the last we have to auction! 3.9 x 3.2 x 3.1cm
I am sorry the locality was not specified for this very large and impressive Chinese calcite specimen; if it were common material, we would know where it is from, but frankly I have not seen this before. It is a plate of GREEN (very unusual for Chinese calcite) poker-chip crystals, u to 3.5 cm across, of pyramidal form. The greener crystals contrast beautifully with an earlier generation of light gray, smaller calcites. Very showy and impressive! 21.5 x 16.7 x 7.4cm
Rhodochrosite nearly completely coats the pyrite-rich quartz matrix on all sides, with a 1.8 cm rhodochrosite pseudomorphing calcite crystal. 8.5 x 5.3 x 3.2 cm
A super-gemmy, 3.5-cm scalenohedral crystal of calcite on matrix, surrounded by a half-dozen SCEPTERED calcites of the same form, with frosty bottoms and gemmy tips! Either one would make this a fine Dalnegorsk calcite, but both together make it really special! Sorry there are no close-ups of the little scepters, but they are quite cool and very unusual for the locality! 7.3 x 6.4 x 5.7 cm

You can see that one cleaved crystal at the bottom of the cluster, and some more of them at the bottom of the back as well, but it is the ones that stick up that really matter on this specimen, particularly on the display side. 4.7 x 4.7 x 3.1 cm
