2.8 x 2.6 x 2.2 cm. A CLASSIC, OLD-TIME calcite specimen from St. Andreasberg, Germany. A complete all-around, lustrous and translucent calcite crystal is nicely attached to a bit of matrix. The crystal has textbook prismatic form and a sharp, nail-head termination. Very nearly pristine. This old-timer dates to the 1800s and comes from an old European collection, where everything dates to the 1800s.
3.0 x 2.6 x 0.9 cm. A UNIQUE and gorgeous crust of lustrous, translucent, botryoidal cobaltoan calcite from the ONE-TIME find at the bottom of the Tynebottom Mine, Alston Moor from the 1970s. The raspberry-red color is so luscious, front or backlit, it looks eatable. Ex. Lindsay Greenbank Collection.
6.6 x 5.4 x 5.4 cm. This specimen, out of the collection of Marty Zinn, gets more fascinating when you look at it closely. Inside this pretty amethyst geode is a single, isolated crystal of calcite. If you look at its surface, you can see that a perfect little sphere of fluorite, one of the botryoidal "egg" fluorites that are well-known from Mahodari, has formed right on the calcite!
8.9 x 6.9 x 6.4 cm. Sharp rhombs of milky calcite in a nice balance with super-gemmy sprays and blades of hemimorphite, on limonite matrix. This vuggy knob of limonite is covered all the way around with these pretty crystals.
5.9 x 5.1 x 3.1 cm. STUNNING glassy blue crystals of fluorite, with gorgeous bevels and internal blushes of accenting purple, from Naica! This is not from the recent finds at Naica, which were primarily clear to green crystals associated with sphalerite. This cluster of crystals was removed completely from the matrix, so it is all fluorite.
2.8 x 2.4 x 2.1 cm. A Michigan CLASSIC - a crystal of calcite inside which you can see inclusions of bright copper. The crystal is complete all around; on the back, you can see bits of copper sticking out from the face of the crystal. Ex. Ed Swoboda Collection.
6.8 x 3.4 x 2.9 cm. Going way back miners at the classic Bisbee locality preserved specimens of the huge variety of calcite found within the mines, as they had no commercial value, but the miners recognized their beauty and variety. This specimen came out of the collection of Dave Stoudt, who had quite a broad array of Bisbee calcites in his collection. This is a stalactitic form of sharp rhombs, with a color tint from inclusions of hematite.
6.4 x 6.4 x 4.4 cm. Going way back miners at the classic Bisbee locality preserved specimens of the huge variety of calcite found within the mines, as they had no commercial value, but the miners recognized their beauty and variety. This specimen came out of the collection of Dave Stoudt, who had quite a broad array of Bisbee calcites in his collection. It consists of a series of very thin sheets of matrix stacked upright, and around them have formed these silky white calcite crystals of very complex form. Ex. Stoudt Collection.
2.8 x 2.3 x 1.5 cm. A thumbnail specimen of a perfectly-formed (and more transparent in person) crystal of calcite on a perfectly-trimmed matrix, from the famous Tsumeb locality. Ex. Willy Israel collection.
6.6 x 5.6 x 4.4 cm. 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 bursting with these fine, golden crystals. Not many fine collector specimens come from Florida, of course!
5.8 x 4.5 x 3.8 cm. Going way back miners at the classic Bisbee locality preserved specimens of the huge variety of calcite found within the mines, as they had no commercial value, but the miners recognized their beauty and variety. This specimen came out of the collection of Dave Stoudt, who had quite a broad array of Bisbee calcites in his collection. This one has piled-up rounded forms consisting of hundreds of densely-packed, wafer-like crystals. They sit up beautifully on the natural matrix "base", and the blue-green aurichalcite on the matrix adds a pleasing color accent.
8.4 x 6.4 x 3.9 cm. This specimen came out of the collection of Dave Stoudt, who had quite a broad array of Bisbee calcites in his collection. It has a captivating tree-like stalactitic form.
15.8 x 11.1 x 5.4 cm. A large and glorious pyrite specimen from a classic Mexican locality not well-known for large and glorious pyrite specimens! Collector Dave Stoudt, according to his records, evidently cherry-picked this piece from a dealer before the opening of the 2005 Tucson Show. It features rounded masses of small, tightly integrown crystals of complex form, intergrown with crystals of light grey calcite.
12.9 x 9.4 x 6.2 cm. A "hedgehog" of scalenohedral calcite crystals, with a sandy, brownish inclusions - in wonderful condition, large and dramatic - ex. Dave Stoudt Collection.
6.7 x 5.4 x 5.4 cm. A gorgeous and unusual Dal’negorsk specimen out of the collection of Marty Zinn. A single taller quartz crystal rises up in the center, surrounded by smaller quartzes that grow out in all directions. Densely intergrown with the quartz crystals are snow-white poker chip calcites.
