19.7 x 15.9 x 9.2 cm. The mineral deposits of Baja are continuous with those of San Diego and many county collectors are happy to own things regardless of political borders. Larson, and the Pala collection, were no exception. This is a dramatic example of the famous amber-colored, translucent calcite crystals found in the 1960s-1970s in the Rosarito Beach area. This specimen was obtained from the Josephine Scripps collection, and is the finest large example of these unusual calcites that we have seen. The large crystal measures 10 cm and all are pristine. Ex. William Larson Collection.
29.0 x 17.3 x 10.5 cm. A huge plate of large calcite crystals from a remote deposit at the edge of San Diego County, in the Anza Borrego desert. A large specimen like this should be considered a museum-sized, quite uncommon, display specimen. Ex. William Larson Collection.
4.3 x 3.4 x 3.2 cm. A briliantly lustrous, sharp single crystal of calcite with origins, according to its old label, from the tunnel project here in St. Gotthard pass. Rare locality specimen, and a good calcite crystal as well. Ex. John White Collection.
6.1 x 5.4 x 2.6 cm. A rare example of beautifully crystallized, acicular uranophane from New Mexico. At first glance, this looks like the Canadian material. However, it is from a small and hard to get locality. Ex. John White Collection.
8.5 x 6.3 x 3.3 cm. A beautiful, stacked cluster of gemmy and lustrous, golden-amber, doubly terminated and twinned calcite crystals from the Elmwood Mine. This striking piece has top color and super gemmy terminations for the renowned locale. Highly representative. Ex. Consie Prince Collection.
8.8 x 7.5 x 3.6 cm. A very fine and rich, two-sided calcite on galena specimen from the historic St. Andreasberg District of Germany. Glassy, colorless calcite crystals richly cover both sides of the sculptural, massive galena matrix. The calcite crystals have the classic shape and form of St. Andreasberg calcites. Old material dating to the 1800s and comes with an old handwritten label. Highly representative of the species and renowned locale.
4.7 x 4.5 x 3.7 cm. This very aesthetic Santa Eulalia specimen features glassy, diverging sprays of light brown hemimorphite blades in an elegant floral pattern attached to a stalk of gossan matrix and very nicely accented with snow-white calcite rhombs. Nearly pristine.
7.1 x 6.1 x 4.3 cm. A fine, old-time, combination specimen from the Old Dominion Mine at Globe, Arizona. The wall of a very well-placed matrix vug is covered with glassy, complex, calcite rhombs, which are beautifully complimented by a multitude of tiny tufts of sparkling, emerald-green, primary malachite needles and by crusts of powder-blue chrysocolla. An attractive combination piece from this historic Arizona locale, probably dating to the 1950s or earlier.
22 x 13 x 13 cm. Webb City calcites are almost a myth in collecting - so few exist to be seen, and so few good ones exist to be owned. This is a fish-tail twinned crystal of huge size, about the size of a football. These are of a rare, unique style found at the turn of the 1900s, in the oldest workings of what was to become the famed Tri-State district in later years. This area today is a disaster site with slumping, empty old cities atop the old mines. This particular specimen would be outstanding from any location, but I think the historic interest as a bonus. It is a nearly pristine, huge twinned calcite with a glowing lavender-pink color when even moderately backlit...presenting just an amazing visual impact without knowing anything about the mineral or locality itself. The only other one like it that I have seen was in the Smithsonian's long-held exhibit on Tri-State material (second photo). I am told by old-timer collectors that most of this material back in the day when found was split along the cleavage planes to make beautiful calcite cleavage chunks for fun and play. Most miners split them in pieces for gifts, paperweights and the like. I had no idea something like this existed on the market to be had, even...until I saw it in the Robert Whitmore collection. He obtained it in an old collection he thinks, sometime in the 1960s. To this day, these remain unique in the world and a major US classic. Ex. Robert Whitmore Collection. Joe Budd photo.
5.2 x 4.4 x 2.7 cm. The Idarado mine is most famous for its Manganoan Calcite specimens. In fact, the largest quantity of the finest quality Manganoan Calcite specimens from Colorado were found in this mine. This piece is a lovely "fan"-shaped group of modified scalenohedral Manganoan Calcite crystals with a soft pink hue. The crystals are translucent when backlit and the overall aesthetics of the piece make it a very good display specimen of this truly classic San Juan material. Ex. Richard Kosnar Collection.
10.3 x 9.0 x 6.0 cm. Sharp, glassy, translucent, hematite-included calcite rhombs to 4.0 cm are richly and very attractively scattered all around on the mounded matrix of an earlier generation of tiny, sparkly, hematite-included calcite scalenohedrons on this fine, complete-all-around and pristine cabinet specimen from recent finds at the mines of Santa Eulalia, Mexico.
4.7 x 3.7 x 3.0 cm. Old Yuma Mine vanadinites compare favorably with the best United States vanadinites, including the Apache and North Geronimo (Pure Potential) Mines. And Old Yuma vanadinites are less common. Lustrous, brick-red, hexagonal vanadinite barrels to 4 mm are richly and attractively scattered on the sculptural, mounded matrix of lustrous calcite rhombs on this classic combination specimen. The knob is complete-all-around and pristine. Ex. Jaime Bird Collection and probably dates to the 1960s or 1970s.
12.2 x 8.0 x 4.5 cm. Lustrous, coloress, nail-head calcite rhombs to 3.5 cm richly and attractively cover the cabinet quartz matrix on this fine, old-time, cabinet, combination specimen from the iron mines of Cumbria, England. This is classic combination material from this renowned locale. Probably old, but no telling how old. Ex. Russell Jones Collection. Outstanding pink fluorescence.
12.0 x 9.0 x 5.3 cm. An unusual, large cabinet calcite rhombohedron from the Taff’s Well Quarry at Cardiff, Wales. The translucent, wedge-like rhomb, with a colorless interior, has about a 1.0 cm thick overgrowth rind of amber, hematite-tinted calcite with very unusual, parallel-growth faces. The top edge is very strange - totally glassy with no overgrowth. Uncommonly large crystal from this locale and the Lindsay Greenbank Collection, a noted English collector, dealer and field collector.
3.1 x 3.0 x 2.5 cm. A beautiful, gemmy and lustrous, golden-amber, doubly-terminated, twinned calcite crystal from the Berry Materials Quarry of Indiana. Textbook crystal form, complete-all-around and interestingly resting on a shard of limestone matrix. Nearly pristine. Classic matrix material from this well-known locale. Ex. Jaime Bird Collection.
