9.0 x 8.0 x 6.5 cm. The Mina Ojuela has produced a new find of this beautiful and striking combination material. Glassy, transparent calcite rhombs to 1.8 cm across are richly and aesthetically strewn in a sculptural vug in starkly contrasting, sturdy gossan matrix. The vug is lined with beautiful, robin’s-egg-blue aurichalcite. Some of the calcite rhombs are included with aurichalcite and some are not, which really adds to the attractiveness of this fine piece.
Hard to capture on camera, but these sharp, scalenohedral calcites (to 3 cm) are dusted with bright pyrite microcrystals to create a big, dazzling Russian showpiece. A couple of tip dings, but hard to notice on a specimen such as this. VERY ATTRACTIVE and, even in the midst of tonnes of minerals, unusual for russia. 11.8 x 6.8 x 5.2 cm
15.0 x 12.2 x 5.0 cm. An excellent, large cabinet calcite specimen from the N’Chwaning II Mine. Two clusters of lustrous, translucent, singly and doubly terminated calcite scalenohedrons are set on a banded hematite matrix covered with sparkly, calcite scalenohedral microcrystals. The calcite crystals have a pleasing light, rose-pink color. This is a large, highly representative example of the species and locale.
4.3 x 3.7 x 3.0 cm. Calcite from the Novotroitskiy Quarry of the Ukraine is very uncommon on the market. A highly gemmy and lustrous, vivid, golden-amber, triangular calcite rhomb has two calcite "wings". These lighter colored calcite crystals are twinned. The color and lustre of this piece is unreal, it looks like the best golden amber. The razor sharp edge is pristine.
7.9 x 5.9 x 5.6 cm. A fine, complete-all-around combination specimen from the venerable Trepca Complex in Kosovo. A dramatic, 3.0 cm, ball of intergown, colorless, translucent calcite rhombs aesthetically rests atop mounded matrix of lustrous, twinned, sphalerite crystals, which in turn, are richly covered with calcite rhombs and scalenohedrons. Classic material from this locale and nearly pristine, with only trivial edge-wear to the 2.0 cm sphalerite crystal. Ex. Steve Smale Collection.
11.4 x 10.3 x 5.5 cm. A striking and beautiful geode half highlighted by a 2.6 cm, gemmy, amber calcite scalenoehdron. The geode is lined with sparkly, dark amethyst crystals and a few, doubly terminated, pencil calcites to 1.3 cm are a very nice accent. The sawed edge has been sprayed with krylon to give it gloss. Ex. Steve Smale Collection.
10.5 x 8.8 x 3.4 cm. Scintillating, multi-hued amethyst crystals coat the terminated portion of a cabinet calcite cleavage on this striking specimen from a new find. The stair-steps and color banding (with smoky quartz highlights) on the amethyst-coated section of the piece are very dramatic. Excellent and unusual material from Irai, Rio Grande do Sul, Brazil.
An extremely uncommon and quite beautiful Dalnegorsk combo specimen, featuring a thin, flat, transparent calcite crystal 7.5 cm across, standing on edge on matrix, with small, glittery apophyllites on the back and top edge. Mined last year at the Nikolaevsky Mine in Dalnegorsk. If you are tempted by the photos....it is MUCH BETTER IN PERSON, as it was so bright and cmtransparent it was really hard to shoot. 10 x 8.5 x 5 cm
5.0 x 2.8 x 2.5 cm. A very aesthetic group of "feathery" scalenohedral Manganoan Calcite crystals with a secondary overgrowth of Calcite and a soft pink hue. The crystals are translucent when strongly backlit. The Idarado mine in Colorado is probably most famous for it's Manganoan Calcite specimens. From the Black Bear vein. Ex. Brian Kosnar Collection.
8.9 x 7.5 x 4.3 cm. This interesting combination piece has calcite in association. A rock matrix has been covered by a layer of botryoidal, green prehnite upon which is emplaced tabular, lustrous, black babingtonite, in crystals reaching 2.8 cm in length. The matrix is unusual and chlorite-rich, so it is green. The sparkling micro-babingtonites add an unusual effect to the piece. The major crystal standing straight up is 2.5 cm tall from one side (showing 2 cm from the calcite-facing side). As an added touch, on the left side of the specimen are white crystals of calcite, to 1.0 cm in length. Lustre on these crystals is high, and the faces are all sharp and un-etched or discolored as with some babingtonite from this locality. These remarkable specimens come out of a very small, previously insignificant quarry that, according to MINDAT, is simply worked by the local farmers.
9.4 x 7.2 x 4.5 cm. Lustrous and translucent, colorless crystals of calcite to 3 cm across form an agglomerated and very bizarre matrix for a single rather large crystal of jet-black babingtonite, 3.7 cm in length. This crystal is starkly frozen there in place, in its translucent "ice" of calcite so that you really have to look closely to believe this is real. It is tabular, doubly terminated, lustrous and just plain sharp in a crystallographic sense - blocky in its geometry. It is elegantly perched in the matrix. It displays well from either side: a second crystal under the first one, 4 cm across, is a bonus. These remarkable specimens come out of a very small, previously insignificant quarry that, according to MINDAT, is simply worked by the local farmers.
This incredibly crystallized calcite specimen has been included by an unidentified mineral thas has turned it an attractive chocolate brown. The crystals are super-sharp and complex, and are piled up on a flat layer of calcite microcrystals that serves as a platform for the larger crystals. Some minor wear but not too much damage that it bothers me as such. A fine English calcite! 10 x 8.4 x 4 cm
A STUNNING specimen in every way. It features lustrous, doubly-terminated calcites to over 3 cm that have grown on a cluster of blue-green fluorite that is layered with a coating of bright, sparkly pyrite selectively deposited on various faces of the fluorites! VERY COMPLEX AND INTERSTING associations here, that are better in person...! 12 x 8 x 4.3 cm
A sharp, lustrous and gemmy, 6 mm magenta spinel octohedron nicely set on the face of a large gray calcite cleavage from Mogok, Burma. Very little new material is coming from Burma, since the US has imposed a trade embargo. 7.2 x 6.0 x 4.1 cm
A showy, CABINET-sized cluster of transparent to translucent and lustrous colorless complex calcite crystals to 3.8 cm on limestone matrix from Asturia, Spain. Asturia is better known for superb fluorite, but this is really a good Spanish calcite. MUCH BETTER IN PERSON! 11.5 x 7.1 x 5.8 cm
