6.8 x 5.4 x 4.7 cm. A large, 4.5 cm, textbook, nearly transparent, colorless calcite rhomb is aesthetically set in bornite-rich sulfide ore and accented with highly lustrous, distorted pyrite cubes. The calcite is included with an unknown mineral and there are even scattered clusters of green byssolite hairs. Classic and excellent combination material from the mines at Concepcion del Oro, Mexico. Ex. Consie Prince Collection.
11.4 x 7.8 x 7.8 cm. A fabulous cabinet calcite specimen from China and the Ed David Collection. A striking, 6.0 cm, translucent, color-zoned, poker chip calcite dominates this aesthetic piece. But, it’s the amazing cluster of graduated size, parallel-growth, poker chip crystals in front of the large poker chips that makes this an extraordinary piece. And the poker chips rest on large scalenohedral calcite crystals. Nearly pristine. Moderate orange fluorescence.
4.9 x 4.7 x 4.4 cm. A sharp, very glassy and translucent, light brown, calcite rhomb from the Shullsburg Mine of Wisconsin. This classic, complete-all-around crystal is nearly pristine. Nicely set on matrix, this gem-like crystal has interesting, modified edges. Old-time material from the George Feist Collection # 999.
4.8 x 3.9 x 2.4 cm. Sparkly, emerald-green dioptase microcrystals cover the calcite matrix on this fine piece from the Tsumeb Mine. This is a highly representative example of the desirable combination from this renowned locale. Ex. Wes Parker Collection.
5.4 x 4.2 x 2.4 cm. An old-time specimen of hackly native silver on massive calcite from the silver mines at Kongsberg, Norway. The silver has a lustrous, variable patina. Highly representative of the species and renowned locale. Ex. Wes Parker Collection.
8.0 x 5.1 x 4.6 cm. This is a pristine cluster of lustrous and gemmy, golden amber, twinned calcite crystals. The largest crystal is 5.0 cm across and fairly equant. This specimen has superb form, color and transparency. These came out in the early 1990s and have not been found since. It remains a unique and immediately recognizable style for calcite.
9.1 x 7.8 x 5.7 cm. Intergrown calcite and massive bustamite are the matrix for prismatic, flesh colored crystals to 7 cm across, and the piece weighs about 500 grams. Bustamite is an uncommon mineral species in crystal form known best from this locality (old workings, though) and from Franklin in New Jersey. Specimens from each appear similar. The calcite even fluoresces in each case. Here, though, the galena crystals embedded in the calcite matrix give it away as Broken Hill material.
3.5 x 2.2 x 1.6 cm. This specimen consists of scalenohedral Manganoan Calcite crystals with a soft pink hue which are associated with minor brownish-black Sphalerite. The Calcite is translucent when backlit and the overall aesthetics of the piece make it a very good display specimen of this truly classic San Juan material. The Idarado mine is most famous for it's Manganoan Calcite specimens. In fact, the largest quantity of the finest quality Manganoan Calcite specimens from Colorado were found in this mine. Ex. Richard Kosnar Collection.
13.9 x 9.8 x 5.8 cm. This is an interesting Indian combination specimen. On a matrix of basalt, drusy white quartz formed first followed by gray spheres of calcite, to 1.75 cm across, then glassy, colorless quartz, to 2.5 cm in length, and lastly, balls of white gyrolite, to 3.25 cm across. The gyrolite has a matte luster with superb translucence.
5.5 x 3.7 x 3.5 cm. A basaltic matrix with a pearlescent, druse of stilbite, acts as the host for two rosettes of royal blue, translucent, cavansite, to 1.3 cm across. Perched on top of the upper cavansite rosette is a transparent, light, amber colored calcite crystal, measuring .7 cm in length.
8.6 x 6.8 x 5.3 cm. This specimen is a fine small cabinet size piece consisting of excellent, sharp, gemmy, lustrous, prismatic, lavender "reverse" scepter and simple prisms of Amethyst measuring up to 1.3 cm sitting atop white/colorless, modified rhombohedra of Calcite on matrix. This piece is remarkable for Bolivia as it features a type of crystallization that is virtually unheard of for this country.
8.2 x 4.5 x 4.1 cm. A classic, beautiful, 4.0 cm, twinned, doubly terminated calcite crystal artfully perched on contrasting, scintillating, limestone matrix from the Elmwood Mine. The pristine, light amber crystal is extremely glassy and the terminations are particularly gemmy. Textbook, outstanding material from this renowned locale.
7.5 x 5.0 x 4.7 cm. Crusts of scintillating apophyllite microcrystals partially cover the front and back and terminations of three, gem-like, sceptered calcite crystals from the Verchniy Mine at Dal’negorsk. The water-clear, modified rhombohedral calcite scepters are beautifully striated and are perched on translucent calcite scalenohedrons. Lustrous, black ilvaite is visible at the base of the specimen, just above the bit of matrix. An excellent and uncommon combination specimen from the locale and the Ryan Bowling Collection. This fine piece dates to the early-mid 1990s and is of a style available today only in recycled collections.
7.2 x 4.8 x 3.2 cm. A beautifully glassy and lustrous doubly terminated calcite crystal artfully attached to two shards of silicified limestone matrix sprinkled with sparkly, golden chalcopyrite crystals from the Sweetwater Mine of Missouri. The amber calcite crystal is transparent on the upper termination. This is a classic, tapered, doubly terminated calcite crystal from this very well-known locale. Ex. Wes Parker Collection.
10.0 x 8.0 x 3.7 cm. The Mina Ojuela has produced a new find of this beautiful and striking combination material. Beautiful, soft-to-the-touch, like felt, robin’s-egg blue aurichalcite needles richly line a vug atop a sculptural wedge of sturdy gossan matrix. A few, glassy, transparent calcite rhombs are scattered about and are included with aurichalcite.
