5.0 x 3.6 x 3.0 cm. A totally gem clear, transparent crystal measuring 1 inch across is perched upright on a bit of matrix and accented by thin translucent white calcite blades. This is a fine miniature from a single characteristic pocket that produced a unique style.
Unusually aesthetic cluster of intergrown calcites, perched on dolomite matrix! No damage - these crystals are complete around the backside as well! 9.7 x 8.7 x 5.2
11.3 x 4.5 x 3.8 cm. A fine cabinet calcite specimen from the Sweetwater Mine of Missouri’s Viburnum Trend. This 10.3 cm, gemmy and lustrous, doubly terminated, amber spear-point is highlighted by the double, interior phantom shown in one of the crystal faces. Iridescent chalcopyrite covering the limestone matrix provides a nice accent to this excellent specimen that was part of my personal calcite collection for many years. The calcite crystal is complete all-around and is very nearly pristine. I obtained this in the mid-1980s. Ex. Rob Lavinsky Collection.
3.0 x 2.7 x 2.6 cm. A fine cluster of two balls of very glassy and gemmy, rose-brown to tan, elongated orthorhombic crystals of olmiite from the new, Fall 2008 find at the N’Chwaning II Mine of South Africa. The balls are aesthetically set on a cluster of very glassy, colorless calcite scalenohedrons. This is a superb example from this find and it really glows a beautiful rose-red with good light.
5.5 x 5.1 x 3.8 cm. A beautiful calcite crystal from the Berry Materials Quarry of Indiana. This large, gemmy and lustrous, complex rhomb has variable, rich, golden-amber color. The complete-all-around crystal has a smaller rhomb fantastically set on its termination. Ex. George Feist Collection.
7.5 x 5.3 x 2.4 cm. A classic and fine calcite specimen from the Tsumeb Mine. This striking, bifurcated specimen features two limbs or sides of opposing, highly lustrous and glassy, stepped-growth calcite rhombs beautifully and preferentially tinted with and coated by hematite. Essentially pristine. Ex. Rob Smith Collection.
8.3 x 6.5 x 6.0 cm. Glassy, transparent, emerald-green fluorite cubes to 2.7 cm with vivid and unusual, purple color zoning form and excellent, 3-dimensional mounded specimen from the Okorusu Mine of Namibia. This fine, pristine specimen is highlighted by the largest cubes being at the top of the piece and the two, highly complimentary, doubly terminated, tan calcite crystals. Older, 1980s material from this well-known locale.
3.0 x 2.3 x 1.4 cm. An interesting and classic miniature cluster of sharp, water-clear calcite rhombs included-with and coated on the back with brick-red hematite from the Tusmeb Mine. The rhombs look like cut, red gemstones under close observation and good light. Ex. Rob Smith Collection.
30.4 x 11.0 x 6.3 cm. A fine, very attractive, elongate, large cabinet calcite plate from recent finds at Santa Eulalia, Mexico. Sharp, lustrous and translucent, amber-colored, dogtooth calcite crystals are partially coated with hematite and have striking, clay-stained, internal, hematite phantoms. Crystals reach 5.8 cm on this piece. This is one of the best large plates from this new find of 2008 that I saw.
4.2 x 3.9 x 2.1 cm. Several small, sharp, sparkling, bright, elongated, dendritic Silver crystals sit atop a matrix of white Calcite. This specimen came out recently when a local collector was able to liberate some specimens from the dumps of this historic mine. The Balcoll mine was worked as far back as the middle ages, so the fact that anything remained (even on the dumps) is amazing. Ex. Brian Kosnar Collection.
20.2 x 12.8 x 9.5 cm. At just over 2 kilograms, this is a large and impressive specimen - but without sacrificing quality. Large Tsumeb calcites of this magnitude were seldom preserved compared to the at-the-time more glamorous minerals from here. This classic style of stacked, sharp, gemmy rhombs, is very geometric and sculptural. In person the piece is very 3-dimensional. Some crystal faces have very light sprinklings of included hematite grains which give them a slight red coloration, when seen from the right angle. Most, however, are very clear and ice-clean, making for a subtle contrast when you see the piece in person. Ex. Rob Smith Collection.
An old-time, classic Michigan Copper Country CABINET specimen of lustrous, transparent and colorless doubly-terminated calcite crystals to 2.4 cm from the famous Quincy Mine. Damage-free. 10.8 x 9.6 x 5.0 cm
A showy CABINET specimen of highly lustrous and transparent hexagonal calcite crystals to 3.7 cm, which have preferentially striated terminations and the crystals are preferentially dusted with marcasite. Attractive damage-free calcite crystals on a matrix of gray limestone. 13.7 x 10.8 x 6.3 cm
A pristine, beautiful, lustrous and transparent golden-amber calcite scalenohedron on a bit of matrix from the Pugh Quarry in Ohio. A classic Midwestern calcite. This crystal is SHARP! It is an old specimen, and the quarry hasn’t produced crystals like this in several decades. 3.7 x 2.7 x 2.2 cm
A excellent Michigan combination piece of a vug of bright, flattened copper crystals surrounded by quartz, epidote, prehnite and calcite from the Globe Mine. A large 1.3 cm calcite crystal is on the back. The locality is now a prison facility, so there wont be any more of these and it has value for that alone, aside from the copper! 4.6 x 3.7 x 2.1 cm
