4.1 x 2.8 x 2.1 cm. A rare and superb Mexican example of copper included inside and on water-clear calcite scalenohedrons from the much less well-known Bufa Mine of Chihuahua. All of the calcite crystals are pristine and if you look down into the crystals, you can see the bright copper inside. The arborescent clusters of spinel-twinned, nicely burnished copper crystals really add character to an outstanding specimen of major interest from a historic find. This looks just like an excellent Onganja copper in calcite, but its not. Ex. Jaime Bird Collection.
4.6 x 3.7 x 3.5 cm. A sharp, pristine, complete all-around, pastel-pink manganoan calcite rhomb accented by an inset rhomb on the top. A secondary overgrowth of sparkly calcite microcrystals is a nice accent. A classic calcite from the Casapalca District of Peru and the Jamie Bird Collection.
3.5 x 3.0 x 2.2 cm. A sharp, absolutely water-clear, colorless, 1.4 cm on the diagonal, calcite rhomb aesthetically perched on matrix from the Tsumeb Mine. The calcite is so clear that you can see the mottled matrix right through the crystal. It looks like a garden inside the crystal. Another of the many beautiful varieties of Tsumeb calcite. Ex. Jamie Bird Collection.
10.3 x 6.5 x 3.8 cm. Manganoan calcite from the San Juan Mountains of Colorado is renowned for its "neon-pink" fluorescent calcite. This superb cabinet spray of pristine, translucent, intergrown, pastel-pink calcite scalenohedrons is from the Treasury Tunnel, which was connected to the Idarado Mine. The mine closed in 1978, so this is undoubtedly older material. Ex. Jamie Bird Collection.
16.3 x 12.8 x 6.1 cm. A superb, two-tiered, large cabinet specimen is aesthetically sprinkled with ball-like clusters of lustrous, tan, sharply crystallized, orthorhombic olmiite crystals and rare, single prism crystals of olmiite. The large cluster is 2.0 cm and the longest single crystal is 1.2 cm. A superb accent is the 1.1 cm, flattened calcite twin. The layered hematite matrix gives the complimentary, ultra-sparkly, water-clear calcite crystal coating a distinct lavender tint. Many of the calcite crystals are doubly terminated. Olmiite is the manganese-dominant variant of poldervaartite and is found only at the N’Chwaning II Mine, its type locality now. Olmiite was not named until 2007.
7.4 x 4.8 x 3.4 cm. A classic, very showy combination specimen from the famous mines at Concepcion del Oro, Zacatecas, Mexico. Interesting, two-toned, velvet malachite botryoids are richly and aesthetically scattered on the 3-dimensional matrix with lustrous, colorless calcite crystals and an overgrowth of sparkly, drusy quartz. One malachite cluster looks just like barbells. Older material from the Mullane Collection.
18.5 x 12.0 x 8.0 cm. This very gemmy crystal is superbly perched on a matrix of gray limestone and has, beautiful, intense color. In person, it is actually quite gemmy with any kind of backlighting. It is much gemmier and more translucent in person than it appears here. The doubly-terminated crystal has an almost beer-colored hue, and it measures 14.0 cm in length x 7 depth x 6 cm width.

6.9 x 4.9 x 3.7 cm. A smorgasbord of Franklin County classics. On this one specimen, you can see reddish zincite, light-colored willemite and calcite, and a fine octahedron of franklinite with smaller crystals and massive franklinite surrounding it, intermixed with the calcite.
5.8 x 4.5 x 3.4 cm. A rare and attractive Bisbee old-time specimen from the Mullane Collection. The well-placed vug in gossan matrix features lustrous, colorless calcite crystals adjacent to rich-green, malachite-included calcite crystals. To top this fine piece off, gemmy brochantite needles richly cover the green calcite crystals. Classic material from the famous Southwest Mine.
8.9 x 5.9 x 3.6 cm. An excellent and showy combination specimen from the Sweetwater Mine of Missouri’s Viburnum Trend. Gemmy, mostly transparent, singly and doubly terminated, light amber calcite crystals are richly and aesthetically scattered on the upright matrix of brassy marcasite crystals. The calcite crystals are up to 2.0 cm long. Ex. George Feist Collection.
3.3 x 3.1 x 2.0 cm. A gorgeous, gemmy, butterfly-twin calcite crystal from the small, one-time find in the early 2000s from Ametista do Sul, Brazil. The water-clear calcite crystal beautifully lies on a sliver of basalt covered with sparkly, tiny quartz crystals. Calcites from this find are rarely available now.
13.8 x 8.5 x 8.5 cm. An old-time, classic, cabinet combination specimen from the famous mines of Frizington, England. Lustrous, translucent, bluish-greenish-grayish tabular baryte crystals to 7.0 cm richly and attractively cover both sides of this piece. A complimentary field of lustrous, colorless calcite crystals is a nice accent. Certainly around 100 years old. Ex. Mullane Collection.
17.5 x 15.5 x 8.4 cm. An excellent, large cabinet calcite specimen. These crystals, up to 3.1 cm across, are unusually transparent for the find, so you can very clearly see the super, star-like, hematite phantoms inside. They also have superb glassy luster. These Leiping calcites are distinctive for their pretty, razor-sharp, symmetrical pyramidal terminations as well. Just an outstanding calcite specimen from a finished find of a couple of years ago.
5.3 x 5.2 x 3.7 cm. A showy, "double-barreled", calcite crystal cluster very aesthetically angled on matrix from the Sweetwater Mine of Missouri. The pseudo-hexagonal, transparent to translucent, lustrous, amber calcite crystals have sharp, pyramidal terminations. The doubly terminated crystal is 5.3 cm long. One side of the sparkly, silicified limestone matrix is richly accented with iridescent, brassy chalcopyrite crystals. Classic Viburnum Trend material from the George Feist Collection, # 270.
5.9 x 3.9 x 3.1 cm. A beautiful, gem-like, 3.5 cm, superbly striated, translucent, light gray, complex calcite crystal aesthetically perched on matrix with smaller calcite crystals. This lustrous, complete all-around calcite crystal looks just like a garnet dodecahedron. Ex. Stoudt Collection.
