5.7 x 3.1 x 2.7 cm. Exhibing parallel growth, these glassy and gemmy, cognac-colored crystals to 3.7 cm in length, have color zoned wispy veils inside and intense color and lustre. Ex. Carnegie Museum Collection.
4.2 x 3.7 x 3.0 cm. Two specimens of lustrous, spear point, colorless baryte crystals, to .5 cm in length. They have grown over colorless calcite. Ex. Carnegie Museum Collection.
8.6 x 6.8 x 4.5 cm. A dog tooth spar, crystal of calcite has been replaced by hemimorphite. Ex. Carnegie Museum and William Jefferis Collection.
9.0 x 4.3 x 3.0 cm. This is a colorless, cave-growth calcite with good luster and translucence and spectacular flowing sculptural form. Ex. Carnegie Museum Collection.
7.2 x 5.4 x 4.3 cm. Doubly terminated, brownish crystals, to .4 cm across abound with colorless rhombohedral calcite, to .7 cm across. Ex. Carnegie Museum Collection.
4.2 x 3.6 x 2.1 cm. On matrix, glassy and gemmy, reddish-orange vanadinite crystals, to .7 cm across with minor white calcite. Ex. Carnegie Museum Collection.
5.6 x 4.9 x 4.6 cm. A fine specimen featuring two doubly-terminated, translucent, golden-yellow calcite crystals set against a matrix covered with small iridescent blue and purple chalcopyrites, on baryte. Ex. Feist Collection.
5.2 x 2.4 x 2.4 cm. A stunning miniature, a stalactite of translucent calcite that is covered with spiky crystals of calcite from a later generation of growth, including a puff of crystals on top that makes it really aesthetic.
5.1 x 4.2 x 2.5 cm. A dramatic "V" of two transparent "nail-head" calcite crystals, from Dal’negorsk. Notice the sceptering on the larger one, where the earlier generation of growth was wrapped by a later one.
12.0 x 11.2 x 7.2 cm. A superb, huge, nail-head, calcite crystal from the famous old lead-zinc mines at Shullsburg, Wisconsin. This translucent, highly lustrous and striated, flattened rhomb is complete all-around. Ex. Phil Scalisi and Joe Freilich Collections.
2.5 x 1.7 x 0.3 cm. A highly aesthetic, curved and twisted, snake-like, silver wire beautifully accented by a flattened calcite rhomb from a mine in Zacatecas, Mexico. The wire is nicely burnished. Classic, older material from the Irv Brown Collection.
8.4 x 5.6 x 4.5 cm. A classic sceptered calcite specimen from Villabona, Asturias, Spain. The lustrous, translucent to preferentially frosted on one side, scalenohedron is abundantly overgrown with rhombohedral calcites in parallel stair-stepped growth, only on the preferentially frosted side. The scalenohedron is capped by a transparent and lustrous, to preferentially frosted, 2.1 cm complex rhombohedral calcite crystal, which makes for a superb sceptered calcite specimen.
11.0 x 7.5 x 5.8 cm. A superb, cabinet jackstraw cluster of doubly terminated, transparent calcite crystals from the famous 2nd Sovietski Mine at Dal’negorsk. The elongated crystal forms, with blocky terminations, look like English calcites and the bit of iron oxide tinting is a very nice accent, adding definition to the lustrous crystals. This is early 1990s material from this famous locale.
10.3 x 6.4 x 5.5 cm. This specimen consists of a few gemmy, sharp, well formed, colorless scalenohedra of Calcite with light red Hematite inclusions which are aesthetically sitting on matrix. Ex. Richard Kosnar Collection.
Another truly unusual and periscope-like specimen, consisting of a hollow tube of Mottramite cast after some now-missing mineral, and coated with translucent, disc-shaped rhombohedral calcite crystals. It looks just like a periscope, even more so than the last piece! Only very minor damage to this delicate and near-pristine, 360-degree specimen! 8 x 4.5 x 3.5 cm
