We call this the "ice cream" pocket for obvious reasons. This is a VERY choice specimen from this one famous pocket of calcite with included copper, that gives it a wonderful pastel green hue unique to my knowledge. The surface looks like sugar, brilliant and sparkly ! This is not a true species per se, but rather a varietal of calcite. Nevertheless, it is unusual stuff from a one-time find , and extremely attractive in any case. They glitter like you won't believe. This is a large one! I am told these came out in the mid-1980s 13.5 x 6 x 4 cm
This oddball is a cast formed as a thin layer of (sturdy!) cobaltian dolomite coated an existing plate of rhombohedral calcite crystals. The calcites then dissolved away, leaving this cast plate with both positive and negative sides showing! 8.8 x 7.6 x 1 cm
A supremely aesthetic and unusual Tsumeb piece with a perfect rosette of calcite, complete, perched nicely on primary malachite crystals! In person, the deep green of the malachite is more readily apparent 3.5 x 3.1 x 1.9 cm
A gorgeous miniature dioptase that doesn't break the bank: this specimen features a main crystal 1.7 cm long and 1 cm thick! It has TOP color, lustre, and is just much better in person than it appears, as with all dioptase in photos. 3.6 x 2.2 x 1.7 cm
A very cute toenail-sized specimen featuring a perfect, sharp, gemmy, lustrous dioptase perched atop a complete calcite rhomb! Stunning contrast! 2.5 x 1.9 x 1.4 cm
Not only do these calcite crystals contain bright copper (a classic Michigan phenomenon), but the copper is actually deposited on an earlier generation of calcite crystals. So what you see are sharp, copper copper-coated PHANTOMS inside the calcites! There are little bruises here and there, but this specimen is more about being interesting than being pristine. This is an OLD specimen! 7.6 x 6.8 x 3.7cm
Some of the crystals from this pocket discovered at the Bor Pit in Dalnegorsk are truly bizarre, with a long, slender calcite crystal running right through the middle of the larger crystal. In fact, the skinny crystal inside this one sticks out of the top of the big crystal and is TERMINATED! 6.0 x 1.7 x 1.4cm
Another of the strange forms of calcite that have come recently from the Bor Pit - this one, a "mushroom" calcite, with one euhedral crystal sitting stop the termination of another! You would think this would be a one-off occurrence, but there were actually dozens of these discovered; who can guess what conditions in the pocket would cause this phenomenon to repeat itself!? 3.6 x 3.3 x 2.5cm
A very pretty toenail-sized specimen of small, bright, gemm and deep green dioptase crystals (better color in person, it just does not come out in pics), on sharp euhedral crystals of calcite! 3.7 x 2.6 x 1.7cm
A GEMMY, golden calcite crystal, 2.5 cm across, nestled in a matrix with stibnite crystals. 7.2 x 5.2 x 3.6cm
NOT AT ALL commonly seen on the market - three gemmy, orange, wonderfully modified crystals of calcite, in a perfect row centered on matrix. The largest of the three measures 3.5 cm. These crystals sit up on the matrix so beautifully and dramatically! Again, this material is QUITE uncommon on the market! 9.8 x 6.5 x 2.6cm
You''re seeing the last of the Leiping calcites - this large plate is actually from a batch that was in the back room of a Chinese dealer, and we bought the only good ones left. These calcites are distinguished by the prodigious size of the fat crystals (up to 5 cm across the sharp pyramidal terminations), and internal hematite-coated phantoms inside of the crystals, formed during the first generation of growth. These are wonderful under UV light! 15.9 x 9.4 x 5.9cm
An aesthetic and pristine, arborescent specimen of lustrous, off-white to pastel-green, bladed calcite crystals from Bisbee, Arizona. This fine, complete all-around piece looks like a cluster of flower petals and hails from the Dr. Ed David Collection. This is classic Bisbee material. 6.8 x 6.7 x 6.0 cm
Among the recent finds of minerals from India are the nail-head, light grayish- green, translucent and lustrous, calcite groups. The largest crystal measures 3.0 cm in length. I particularly like the lovely growth striations that look like terraced rice paddies. THIS IS ONE OF THE VERY BEST specimens I saw from the find, in terms of quality , aesthetics, and color saturation. 5 x 3.5 x 2.6 cm
This is another group of nail-head, light grayish-green, translucent, highly lustrous, calcite crystals perched on a bed of much smaller, disc-shaped, translucent calcite crystals. The largest crystal is 4.0 cm across and displays the same superb growth patterns as the previous specimen. THIS IS ONE OF THE VERY BEST specimens I saw from the find, in terms of quality , aesthetics, and color saturation 6.75 x 4.8 x 3.7 cm
