Lustrous, honey-brown smithsonite rhombs richly cover one side of this showy, two-sided crust of lustrous dolomite casted after calcite from Tsumeb. The large, central dolomite casted after a large calcite crystal looks like the superstructure of a ship. 9.3 x 4.8 x 3.6 cm
A showy mounded specimen of lustrous, preferentially hematite-tinted, doubly terminated calcite crystals to 1.7 cm with pryite cyrstals on massive pyrite matrix from the Gloria Mine of South Africa. Scattered damage to a few crystal tips and one small area are certainly not detracting from this two-sided piece. 5.7 x 4.7 x 4.5 cm
A BEAUTIFUL and AESTHETIC CABINET specimen of two, pagoda-like, stacked clusters of highly lustrous, translucent, triangular, grayish-cream with orangish accents, nailhead calcite crystals on matrix from the Williamsville Quarry in Missouri. A couple of super-trivial edge bruises are certainly not detracting from this very showy piece. note was erroneously attributed to the Gary Hansen Collection, but was recently collected 11.3 x 8.7 x 8.0 cm
A large, complete fossil clam filled with golden calcite crystals! This fascinating specimen formed when gemmy calcite crystals grew in the natural pocket formed by a buried fossil clamshell. The interior of the shell is now completely covered with these fine, golden crystals. Not many fine collector specimens come from Florida, of course! This is a LARGE and FINE example from this fascinating find - it is very hard to get the complete, big ones such as this - we picked up a few from a contact when we were in Tucson. 10.7 x 10.6 x 7.2cm
A BIG 7-cm crystal of calcite, translucent-to-transparent, with pretty, undulating faces - decorated with shimmering bowties of stilbite. This is just a wonderful, large glowing crystal, overall a truly aesthetic piece - 11.4 x 10.1 x 8.2cm
Irai was known for these superb, gorgeous 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 - like this large one, with superb crystals to 6 cm in length, on a pretty bed of smaller calcites with the dove-gray underying mineral showing through to provide contrast for the creamy large calcites! 16.8 x 13.4 x 6.9cm
A lone, gemmy, sharply terminated crystal of selenite juts dramatically from a bed of euhedral calcites! The specimen looks great from all sides. NEVER see them on calcite matrix! 7.1 x 5.4 x 4.9cm
4.0 x 3.7 x 3.0 cm. A stunning, gemmy, water-clear crystal with incredible lustre, on a pedestal of smaller ones. This piece is from a new find of shocking quality from France. I have seen just a few on the market, from only one source, recently. This is some of the finest gem calcite I have yet seen, and I am told the find was very small.
There have been only two really decent batches of these gorgeous irai calcites over the past couple of years, and we were able to cherry-pick both of them. This is from last years batch, A really significant WHOPPER specimen, with fine silky crystals pointing in all directions. The specimen is a cast of calcite, concave on back, which still retains the impression on the back of the rock surface on which is formed. Big, showy and impressive! 29 x 14 x 4 cm
A SUPERB and AESTHETIC specimen of gray, metallic-bright galena crystals resting in a house-like box-work of pastel-pink manganoan calcite after a calcite cast. This is a UNIQUE and BEAUTIFUL specimen from Naica. Ex Richard Hauck Collection. 5.4 x 5.2 x 3.7 cm
A BEAUTIFUL Tsumeb specimen of lustrous, translucent and colorless calcite rhombs to 1.4 cm on nicely contrasting green, bayldonite-coated matrix. Most of the calcite rhombs are included with a rust-brown mineral. All of the major calcite rhombs are undamaged. Ex Edna Doughty and Richard Hauck Collections. 6.2 x 5.1 x 4.0 cm
A showy, beautiful and pristine specimen of lustrous, translucent and colorless calcite scalenohedrons to 5.3 cm from the famous San Antonio Mine at Santa Eulalia, Mexico. Some are doubly-terminated, impaled by others. Choice material from the Marty Lewadny Collection. 5.3 x 4.9 x 3.0 cm
This fluorite specimen, mined in 1991 at the Minerva Mine, shows some gorgeous zoning! The larger crystals have yellow interiors with purple outlines. The smaller ones have purple interiors, with a stripe of teal-blue in the clear part outside the purple core! Somehow, these crystals, though in the same cluster, formed at different times when the solution in the pocket varied, leading to the differences in hues as the crystals grew. Note the little calcite decorating the crystal faces as well! 9.1 x 7.8 x 7.5cm
These superb crystals of the top Tsumeb color and luster measure up to 1 cm! They are on white calcite, the optimal setting to really show them off. There are crystals all the way around this shard of matrix, which was exposed all around in the pocket. Labels show this specimen to have passed from Luis Leite to Gene Schlepp in the past. 4.9 x 2.8 x 2.7cm
What you are looking at is the intergrown tips two stalactites of calcite upon which have grown a burst of big, translucent crystals of calcite! These crystals are in pristine condition, and the specimen can be displayed from all sides! The crystals are quite large, to 4 cm in length, and beautifully sharp. Even if this were just a specimen of calcite crystals, it would be excellent - but as a unique stalactite specimen, it is even better! WOW! 9.8 x 9.2 x 6.4cm
