22.9 cm tall. This is a huge and incredibly pristine, complete 360-degree cluster of giant feldspar crystals from this important locality. At 12.8 pounds, 9 inches tall, it is dramatic and impactful. Even more, it is a floater cluster of two large crystals with no attachment points, complete all around. It is partially covered with cleavelandite and with a nice smoky quartz crystal for accent. Ex. William Larson Collection.
6.9 x 6.6 x 1.8 cm. A beautiful specimen from recent finds at the Pederneira Mine. Pearlescent florets of snow-white cleavelandite blades aesthetically surround a lustrous, cranberry and green tourmaline. The very sculptural quality and contrast of the cleavelandite against the tourmaline make for an excellent Pederneira combination specimen.
13.8 x 13.8 x 10.5 cm. A dramatic cabinet specimen from the less well-known Pack Rat Mine of San Diego County. Gemmy and lustrous, reddish-orange spessartine garnets are festooned on the starkly contrasting, mounded matrix of snow-white albite. This is seldom available, large material, and only available from insider collections. Older material from the Chuck Houser Collection.
4.7 x 4.5 x 4.0 cm. This is a rare and aesthetic combination specimen from the famous 1980s finds at Stak Nala, Pakistan. A 3.3 cm, gemmy and lustrous, doubly terminated, polychrome tourmaline is set on the side of a euhedral, pristine, floater albite crystal. Few Stak Nala toumalines have as much pink as this beautiful crystal does. The pink grades downward to two shades of green before reaching the colorless basal termination.
12.5 x 7.6 x 6.8 cm. This is a classic old Massachusetts specimen, of a kind found only seldom now in old museum collections and older personal collections. I am told that these sharp crystals are actually caught in altering (or altered fully to) a mix of muscovite and albite. This is a stark, aesthetic, display sized specimen with really nice geometry to it. While I do not know an exact locale on this, it is most likely from the Goshen Area, Hampshire County, with references from Emerson (thanks to Jim Chenard for looking this up in the old books). Ex. Robert Whitmore Collection.
6.0 x 5.0 x 4.5 cm. A classic, 3.3 cm, gemmy and lustrous, tabular aquamarine crystal set on a matrix of smaller aquamarines, sharp snow-white albite crystals and pearlescent muscovite plates from recent finds at famous Mt. Xuebaoding, China. The aquamarine has good color and complex edge crystal faces. Highly representative of these species and noted locale.
4.6 x 4.0 x 2.6 cm. A sculptural and aesthetic combination specimen from recent finds in Pakistan. The V-shaped albite crystal matrix is beautifully accented with gemmy, cherry-red spessartine crystals. The coup de grace of this specimen, though, is the centrally located pearlescent, muscovite "sail" with the two, gorgeous, isolated spessartines and the spessartine cluster at the base of the muscovite blade. Classic combination material from Shengus.
6.3 x 5.9 x 5.7 cm. Enhanced by a wreath of bladed, white albite crystals at its base, is a glassy and translucent crystal of multicolored elbaite tourmaline, measuring 5 x 5 x 4.5 cm. Most of the elbaite is an inky blue-black color at its core, visible with good backlighting. However, the top 1 cm or so is a much more translucent, sky-blue color. Very nice and unusual tourmaline, complete-all-around. Weighs 279 grams, mostly in tourmaline mass.
11.6 x 9.1 x 7.7 cm. A lovely muted-red color, gemmy, rather lustrous group of modified/etched trapezohedral Spessartine crystals sit atop porous, etched, lustrous white blocky crystals of Albite with minor Muscovite. The piece is very three dimensional showing beautiful overall form and aesthetic quality.
4.0 x 2.8 x 2.0 cm. Two lustrous, translucent, rich yellow-green titanite crystals are aesthetically set in sculptural matrix of bladed muscovite rosettes and albite on this fine specimen from the well-known Tormiq Valley of Pakistan. The alpine clefts at Tormiq have produced a wide array of very fine minerals and this is certainly one. Both crystals are pristine and the right crystal is sharply twinned.
5.0 x 4.2 x 3.5 cm. A 2.2 x 1.8 cm, gemmy and lustrous, apatite crystal is attractively set in pearlescent, bladed cleavelandite on this aesthetic specimen from an unknown mine in Brazil. The textbook, hexagonal, pink apatite has interesting color zoning and modified corners.
8.4 x 3.4 x 2.4 cm. A striking, very fine tourmaline from recent finds at the Pederneira Mine. This very gemmy and lustrous, doubly terminated, tapered crystal is dramatically accented with large, pearlescent cleavelandite plates and beautifully and richly dusted with contrasting, purple lepidolite crystals. Nearly pristine. The upper, thick half of this rich, green crystal has a cranberry-red core, making this a watermelon tourmaline.
8 x 6 x 5 cm. This is a fine old classic but also an aesthetic, well-balanced specimen for any titanite locality, featuring a doubly-terminated, pristine, lustrous, 4.5 cm crystal of translucent green twinned titanite perched on contrasting white matrix of pericline feldspar. Ex. Robert Metzger and Schwethelm Collections.
15.9 x 12.0 x 7.8 cm. Two totally gemmy, water-clear, colorless topaz crystals to 3.0 cm. The crystals have very complex terminations and project outward from the large cabinet specimen dominated by a huge, sharp feldspar crystal. Smaller topaz crystals, pearlescent, bladed cleavelandite and muscovite enshroud the matrix. An impressive large combination specimen from recent finds at Dassu, Haramosh Mountains, Pakistan.
6.0 x 4.5 x 3.3 cm. A classic, older combination specimen from the Himalaya Mine. Two gemmy and lustrous, bi-colored tourmalines are aesthetically set on the side of a sharply terminated, water-clear smoky quartz crystal. The tourmalines have beautifully gemmy pink bodies with striking gray terminations. The large tourmaline is 3.7 cm and the single cleavelandite blade is a fine accent. This fine and seldom available Himalaya combination piece probably dates to the 1970s or 1980s, possibly earlier. Ex. Saller Collection.
