6.9 x 4.4 x 3.4 cm. A really elegant cluster of translucent scalenohedrons of calcite, on a greenish copper-rich matrix, from Irai. The long crystal here is 5 cm.
4.4 x 3.9 x 2.6 cm. A cluster of Missouri calcite crystals of fine sharpness and luster, with brassy little chalcopyrites on the crystals surfaces, and inclusions of hematite. Ex. William Sanborn Collection.
12.2 x 9.2 x 2.6 cm. These crystals are like razor-sharp bars of glass. The color you are seeing is from a layer of a dark mineral underneath the crystals. The calcites themselves are absolutely colorless like water. The largest crystals measure 3.5 cm. They sit on a bed of small quartz crystals.
6.0 x 4.6 x 3.9 cm. A superb, complete all-around and pristine cluster of blocky, lustrous, porcelaneous, lead-rich calcite rhombs from the Tsumeb Mine. The large, dominating rhomb is 3.4 cm, in the long dimension. This specimen is further highlighted by a very aesthetic scattering, at the base, of brown, botryoidal coronadite or some other oxide. Ex. Rob Smith Collection.
9.8 x 8.1 x 6.2 cm. A fine, old-time cluster of gemmy and lustrous, amber calcite rhombs from the historic Tri-State District of Missouri. The beautiful, large, upright, dominating rhomb in the front is 6.6 cm across. Ex. George Feist Collection # 2469.
7.1 x 3.0 x 2.6 cm. Piemontite is a rare, red epidote group silicate. This is a fine combination specimen from the famous No. 5 shaft at the Messina Mine of South Africa. Red piemontite microcrystals richly and preferentially cover three sides of a doubly terminated, sharply trigonal, transparent to translucent quartz crystal. Calcite crystals and kaolinite are additional, complimentary accessory minerals on the glassy quartz crystal. This is a fascinating doubly terminated quartz crystal, with one end being a sharp, single termination and the other end being multiply terminated. Ex. G.R. Glover Collection.
9.4 x 7.7 x 5.5 cm. A jewel-like calcite specimen of glassy lustre, transparency, and striking brightness, from the classic mines here that hit their heyday in the late 1800s. This fine specimen has crystals to 1.5 inches or 3.5 cm, and is nearly pristine. This is likely 100 years old and is a fine example of this classic calcite style from England. From an old private collection.
highly lustrous, translucent wheat-sheaf shaped manganocalcite crystals to 1.6 cm on massive bornite matrix from the famous and closed Magma Mine, Arizona. This is a very rich and important locality specimen. Fluorescent, too. 7.5 x 6.4 x 5.4 cm
An extremely specimen consisting of three elegant blooms of very pale pink managanocalcite crystals, on a bed of quartz with pyrite. Very striking and pretty, with no damage! 8.1 x 6 x 2.3
A razor-sharp, gemmy calcite crystal with gorgeous faces from the classic Swedish calcite locality.Natural contact in back, NO damage! These are normally very expensive , as they came from a small pocket and are treasured by the locals. 5.6 x 2.5 x 1.8
An exquisite combo specimen with platy, delicate pink manganocalcites that are intergrown with fine quartz needles. The manganocalcites are nicely separated, and quartz needles have actually grown on them, for a really beautiful effect. 5.4 x 3.8 x 2.4 cm
Yet another really pretty manganocalcite specimen in this auction, a floater cluster of crystals to over 2 cm with a delicate pink shade. 4.6 x 3.6 x 2.8 cm
Two big, fat, doubly-terminated crystals of good creamy-gold color, with high luster, jutting dramatically from the matrix. Nice! 11.5 x 7 x 6 cm
8.4 x 4.3 x 3.8 cm. A classic calcite for this locality, with super sharp, hexagonal, crystals showing translucency and color zoning. The crystals are to just over 1 cm in size.
7.6 x 6.1 x 4.7 cm. Sharp, classically formed hexagonal calcite from this old locality, with crystals to 2 cm nicely displayed on matrix.
