10.4 x 6.5 x 5.8 cm. Mexican schorl specimens of this sharpness and combination quality are rare. A sharp, 7.0 cm, quartz-frosted, smoky quartz crystal is strikingly set amidst clusters of radiating, lustrous, jet-black schorl crystals. Part of the schorl crystals are also coated by the drusy quartz, adding to the effect of this dramatic cabinet specimen. This very fine specimen is from an uncommon Mexican locale - Santa Cruz in Sonora. Ex. Consie Prince Collection.
5.9 x 4.8 x 3.5 cm. Matrix “Herkimer Diamond” quartz specimens are rare because the crystals commonly break off matrix during collecting, as the matrix is usually very hard. The sculptural, mounded matrix on this fine specimen is covered with a multitude of small, glassy, transparent smoky quartz crystals. Water-clear, gem-like quartz "diamond" crystals strikingly dominate the specimen. The large crystal is 1.4 cm. Nearly pristine. This is a rare, visually impressive, complete-all-around, matrix Herkimer diamond specimen from this renowned New York locale. Ex. Daniel Trinchillo Sr. Collection.
15.4 x 13.5 x 6.0 cm. A huge and impressive smoky quartz crystal from a classic Connecticut locale - the Morris Dam Quarry. This glassy, translucent giant has rich, variable, smoky color and the internal crazing adds character. Ex. Russell Jones Collection. Weighs 4.0 pounds.
7.3 x 4.1 x 1.9 cm. Three splendent, interpenetrating, drill-bit-twinned cinnabar crystals are aesthetically set on a sculptural plate of glassy quartz needles and nicely accented with cream-colored dolomite rhombs on this outstanding specimen from Tongren, China, the premier locality for fine cinnabar crystals. The superb, central crystal is 1.8 cm and all three crystals have this beautiful, "ruby-silver" look to them, just like proustite or pyrargyrite crystals. The striking center and left crystals are pristine. The right crystal’s termination is pristine and the periphery contacting on the side is mostly out of sight. Ex. Wally Mann Collection. Wally bought this gorgeous piece from Bill Larson at the Pala Properties office in Fallbrook in 1985, just when specimens from China were starting to reach the market.
5.7 x 5.1 x 3.1 cm. The famous mines at Dal’negorsk have produced world-class calcite specimens and this is an excellent example. This very sharp, glassy, translucent, light pink manganoan calcite poker-chip crystal is a complete floater. The only point of attachment is on the rosette of quartz crystals. Ex. Gene Meieran Collection. The accompanying label dates the piece to the very early 1990s, when Dal’negorsk material was just starting to reach the market. Superb orange fluorescence.
6.0 x 4.4 x 3.8 cm. A striking, gem-like “Herkimer Diamond” quartz crystal from the famous deposits at Middleville, New York. The water-clear crystal is doubly terminated and looks like it was faceted. Ex. Daniel Trinchillo Sr. Collection.
19.7 x 10.0 x 4.4 cm. A dramatic and sculptural, large cabinet smoky quartz specimen from a new find of summer 2009 in Minas Gerais. These smoky quartzes have the striking "alligator" look, where the quartz crystals look like the large plates in an alligator’s hide. Many of these very glassy, transparent smoky quartz crystals have distinctive darker crystal edges and are doubly terminated. This particular piece looks like smoky icicles or old tree bark. Overall, this excellent, complete-all-around, large piece is nearly pristine. Stunning new material and a superb and sharp piece of very high and select quality, that we picked from a large lot imported in mid-2009.
18.2 x 8.6 x 5.5 cm (largest). A stunning large cabinet pair from a sliced and polished hollow, very elongate colony of coral - you can see the pattern on the outside - that has been replaced or filled inside with botryoidal and banded chalcedony. The lustrous botryoids have a gorgeous variety of color. They look like pearls. This is one of those unusual cases where biology meets mineralogy. This dramatic specimen is from the Hauck Collection.
6.6 x 4.4 x 3.8 cm. Scintillating, gemmy, emerald-green dioptase crystals to about 6 mm are very richly and aesthetically nestled on contrasting powder-blue plancheite on a 3-dimensional quartz matrix. Lovely contrasting colors in this fine piece. Ex. Charlie Key.
8.4 x 5.9 x 3.5 cm. A very aesthetic specimen of a 2.6 cm wide cluster of two intergrown balls of lustrous, bladed, royal-blue cavansite crystals dramatically perched at the top of narrowing, thin crust of drusy quartz peppered with pearlescent stilbite blades and a few scattered, discrete cavansite blades from recent finds at the Wagholi Quarry.
3.6 x 1.9 x 1.8 cm. A beautiful, water-clear, facet-like smoky quartz crystal with wonderful lustre. Crystals like this, from this famed Swiss locale are the epitome of smoky quartz crystals. Complete-all-around and pristine, except for the contacting at the base. Classic, world-class material for the size, a miniature.
10.3 x 8.8 x 3.2 cm. A striking, very uncommon, two-sided, cabinet specimen from the less well-known San Vicente Mine at Guanajuato, Mexico. One side of the thin, banded, amethyst crust is festooned with very striking, layered, "sandwich style", poker-chip calcite crystals to 1.4 cm. The poker-chip crystals are coated with a druse of secondary calcite, giving them an interesting sugary appearance. The other side is dramatically studded with pretty purple amethyst crystals. This is a very fine and rare combination specimen from this historic locale.
14.8 x 9.3 x 7.8 cm. Quartz specimens of this impressive quality are relatively uncommon from "near" the well-known Iron Cap Mine of Arizona. This cabinet specimen is highlighted by the dramatic, rare for the locale, 9.3 cm quartz bowtie. Another bowtie is next to it and the upright isolated crystal is an interesting accent. The larger crystals have a pleasing pink tint to them, probably from iron oxides. Ex. Evan Jones Arizona Collection. Unusual.
12.4 x 6.2 x 4.5 cm. A striking cabinet specimen of intergrown, sparkly, drusy quartz stalactites from recent finds at Jalgaon, India. This is a complete-all-around, very interesting piece. One side is densely overgrown with small, secondary stalactites and portions of the piece have a gray tint, while the rest is colorless. Small, gem-like, water-clear apophyllite crystals are scattered about as a fine accent. The terminations were contacted against the vug ceiling.
5.0 x 4.3 x 2.8 cm. Beautiful, vibrant, grape-juice-colored amethyst crystals sit upon matrix of contrasting milky quartz crystals. This one-time find at a construction site was found at the Saltman/Plumbago Amethyst Locality near the Camp Encore kids’ camp. Ex. Jesse Fisher Collection and purchased at the 1989 Denver Show.
