5.5 x 5.2 x 4.1 cm. The Pederneira Mine of Brazil has produced an incredible and beautiful variety of tourmalines during its long productive history. This amazing and very aesthetic piece highlights the forces of nature in a pegmatite. The superbly placed, 4.4 cm, gemmy and lustrous, highly striated, teal-green tourmaline crystal was totally sheared in half by pocket forces, but remains attached to the beautifully complimentary, pearlescent, bladed cleavelandite crystals. Close examination of the sheared zone reveals that both halves of tourmaline healed and began renewed growth. The lower section has a raspberry-red, inner core. The pyramidal termination is lightly etched. The contacted watermelon tourmalines in the background, at the top, is a nice accent. A lovely and unusual matrix tourmaline from this renowned locale.
22 x 15 x 11 cm. This stunning, large matrix aquamarine specimen is from a unique find of several years ago. Like others from this find, it has a unique 3-dimensionality to it, in addition to fine color and luster. The piece is dramatic, for the way the starkly contrasting crystallized albite matrix serves as host to the gemmy, glassy, unusually isolated and upright crystals. There are 2 small repairs (one to the smallest aqua, and one to the base junction of the middle large aqua crystal). The aquamarines from this find are very blue and gemmy, with internal phantoms of medium opacity running up halfway through the larger crystals. This is a characteristic of this now-infamous pocket found in late 2005 and brought to market in 2006, unique in three factors: crystal quality and color; the unusual internal phantoms; matrix aesthetics; and the fact that the albite matrix is crystallized nicely. Ex. Gene Meieran Collection.
9.8 x 8.7 x 3.1 cm. This is a bizarre Pakistani specimen, quite different from any rutile I have seen before from this region. It is a very aesthetic piece with a crosshatched cluster of pipe-like (for lack of a better word) rutile crystals that runs along the plate of albite and green titanites, like irrigation pipes with a few outlets sticking up here and there. Ex. Richard Kosnar Collection (he specialized in minerals of the world's alpine type deposits).
4.4 x 4.2 x 4.0 cm. A gemmy and lustrous, 2.1 cm, vivid pink tourmaline is aesthetically set between two sharp, glassy, smoky quartz crystals. The specimen is very nicely accented by a spray of pearlescent, bladed cleavelandite. Classic material from the Himalaya Mine of California.
A DOUBLY-TERMINATED FLOATER crystal measuring a full 4 inches long, accented nicely by albite blades about its lower quarter! Approx 72 grams. NO REPAIRS, which is remarkable for such a large crystal from this mine. 9.3 x 2.5 x 2.2 cm
7.4 x 5.1 x 4.3 cm. This is a superb small cabinet sized specimen with a sharp, water-clear, aqua-blue crystal of aquamarine perched totally vertical and emerging from a mass of crystallized albite matrix. The aquamarine is itself 4 cm tall. It is complete, and terminated, though has a weird growth asymmetry/indentation atop which accents the normally flat and typical termination. This crystal has a micro-thin layer of secondary aquamarine crystallization over the surface of the crystal, giving it, in person, a slightly frosted and sugary appearance which is unusual. Ex. Dr. Stephen Smale Collection.
23.5 x 14.9 x 6.4 cm. Sharp, stout, lustrous, pearlescent albite variety pericline crystals to 6.4 cm richly cover an impressive, large cabinet specimen from the Habach Valley of Austria. Some of the crystals are distinctive albite twins. This is a dramatic and showy large piece, with rich crystal coverage and is minimally impacted by the growth contact on the large crystal, which has re-crystallized. From the collection of noted Alpine collector, Rolf Wein.
5.2 x 5.0 x 2.5 cm. Gemmy and lustrous aquamarine crystals are artfully set, jackstraw-fashion, on both sides of the sculptural box-work matrix of casted feldspar. The striking, large, "sentinel" aquamarine at the top is 1.7 cm. A few of the smaller aquamarines are doubly terminated. The aquamarines are particularly gemmy.
13.9 x 9.0 x 5.8 cm. Gemmy and lustrous, wine-red spessartine garnets to 1.0 cm richly cover the cabinet-sized matrix of contrasting, white albite crystals from recent finds at Shengus, Pakistan. These garnets are exceptionally gemmy for the locale, so this is a highly representative, large specimen for the species and locale. The garnets are very lustrous and these are modern classics.
5.8 x 5.0 x 3.6 cm. A classic, sharp, gemmy and lustrous, pastel-pink morganite crystal nicely set upright on cleavelandite and quartz matrix from recent finds in Nuristan, Afghanistan. The 4.1 cm morganite has textbook, hexagonal crystal form and is pristine on the front, top and sides. There are even a few, green, pencil tourmalines on the lower right as a further compliment.
10.4 x 5.3 x 4.8 cm. An old-time cabinet specimen from the famous Abija N. Fillow Quarry pegmatite at Branchville, Connecticut. Lustrous, pearlescent cleavelandite blades in a jackstraw pattern comprise this showy piece from a historic locale. The quarry opened in 1876 and the piece comes with an old, cloth label glued to the back. Ex. Mullane Collection.
9.9 x 8.2 x 6.4 cm. A fine and unusual specimen from the Richard Hauck Collection and Minas Gerais, Brazil. The water-clear quartz crystals are heavily invested with schorl needles. None of the multitude of schorl crystals protrude out of the quartz crystals. I like the jackstraw pattern of quartz crystals and how the pearlescent cleavelandite compliments and accents the dark, included quartz crystals. The two, tiny, schorl-included quartz crystals on the cleavelandite are a very nice accent. The large quartz crystal is 9.5 cm and is doubly terminated. The lower, large quartz crystal is also doubly terminated and is 9.0 cm long.
6.1 x 6.1 x 4.5 cm. An old-time, uncommon specimen of gray-brown and rust-red albite pseudomorphs after two, sharp, side-by-side scapolite crystals nicely nestled in a matrix vug. This unusual, old-time pseudomorph is from the Louis Zara Collection.
A riveting purple-capped foitite on contrasting rosettes of stark white albite makes this a highly unusual specimen . The termination is perfect save for a tiny ding on the leftmost small edge which does not visually detract. The purple color is visible, nicely enough, with only minimal back-lighting required and these shots were taken without a particularly strong light. 6.2 x 5.5 x 4 cm
The major crystal has a glassy, lustrous termination measuring 1.5 x 1.7 cm across. Ex. collection of Dallas collector Wally Mann. He obtained it over 15 years ago when the Houston Museum deaccessed some specimens locally from the Perkin and Ann Sams collection. 8.9 x 5.8 x 4 cm
