8.8 x 6.0 x 4.6 cm. A large hexagonal crystal of morganite from San Diego is a rarity. It has a rich pink color. The surface is mildly etched, but still retains lustre and the etching just makes it more reflective. Weighs 361 grams. Ex. Pala International/William Larson Collection.
8.8 x 6.6 x 5.5 cm. This superb specimen from the 1960s-1970s here is both aesthetic and fine in quality. It features a rich pink 4 x 3.5 cm crystal of gemmy morganite, perched on contrasting white matrix. Not only is it on contrasting matrix, but it is on contrasting crystallized matrix. The contrast to the bladed cleavelandite and the prismatic quartz is striking, geometrically, and enhances the composition of the piece. The pink color in this crystal is exceptional for the mine and comparable to modern morganites from Pakistan in color. Larson obtained this from the mine owner, Norm Dawson, in the 1980s. Ex. Pala International/William Larson Collection.
3.7 x 3.1 x 2.9 cm. A really fine matrix-free cluster of aquamarine crystals from the Erongo locality - all growing out from a central point. All but a couple of little sidecar crystals are terminated. The crystals measure to 2 cm in length.
A GEM crystal, much better in person, with a distinct deep blue color and excellent glassy lustre 3.5 x 0.5 x 0.4
5.9 x 2.2 x 2.0 cm. A gemmy, water-clear, 5.7 cm aquamarine crystal aesthetically attached upright to a shard of cleavelandite, muscovite and schorl matrix from the Dassu area of Pakistan. The aquamarine crystal is pristine and has excellent, medium-blue color saturation.
9.2 x 2.0 x 1.5 cm. Dudley Blauwet, who brought this rare specimen back from his travels, describes it as beryl - it is blue with a greenish cast. This is a superb cluster for this locality. The crystals are gemmy, doubly-terminated, and have super luster. They light up a beautiful blue-green under good light (not colorless as it appears in the photo). Both the main crystal and the sidecar crystal are finely terminated. Weighs 30 grams.
5.2 x 4.4 x 1.2 cm. This is an extremely unusual aquamarine for the Erongo locality. Tabular crystals with regular hexagonal form are well-known from Pingwu and other localities, but here the hexagonal form is stretched and elongated on the C-face. The crystal is very gemmy for Erongo, with good color. The crystal has a nice flat termination. Weighs 37 grams.
8.7 x 1.4 x 1.4 cm. A superb gem tourmaline from Pakistan, doubly-terminated with a complex multi-level termination at the bottom end. The crystal is very gemmy for almost its entire length, with glassy luster. Weighs 26 grams.
A Russian specimen with emerald crystals to 1 cm along with cassiterite crystals to 0.5 cm. Though the crystals are not fine, this was considered quite an important reference combination specimen. It was in the Matwich Collection (he worked in the South Kensington Museum, which later became the Victoria and Albert Museum, from 1860 – 1890). From there it went to the collection of B. W. Anderson, director of the world’s first gem lab, who worked there from 1926 to 1972. Later, it passed through yet another collection (John Saul, noted miner and gem collector) and through one dealer on the way to me. Not exactly a spectacular cassiterite I admit, but an important piece nonetheless. 3.3 x 3 x 1.7 cm
12.4 x 5.4 x 2.9 cm. Half-a-dozen large, gemmy, light blue aquamarine crystals, of hexagonal, tabular form, from Pingwu. These aqua crystals are gemmy and lustrous, with very interesting "cut glass" growth anomalies on their side faces. The largest crystal measures 3.5 cm across, and is a chunky 1.5-cm thick. Typical muscovite-covered matrix.
6.4 x 5.2 x 5.0 cm. A superb and aesthetic matrix aquamarine specimen from Pakistan and the Dave and Emily Stoudt Collection. A gorgeous, 3.3 cm, gem-clear aqua crystal with a very interesting, modified pinacoidal termination is dramatically set in a "boulder" field of sharp, blocky albite crystals.
8.5 x 5.0 x 4.6 cm. A large, beautifully pink, partially gemmy morganite crystal perched upright on quartz matrix from the famous Golconda Pegmatite of Brazil. The sharp, euhedral morganite crystal is undamaged on the front, sides and top and is 6.9 cm across. It is also fat, at 3.2 cm thick. Probably mined in the 1960s or 1970s.
3.2 x 1.0 x 0.7 cm. This is a vibrant green, lustrous crystal of a rich green color - quite uncommon from Brazil. In person, it has more apparent lustre. The termination is unusual in that it is prismatic (if shallowly so) instead of flat as usual for an emerald.
10.3 x 6.4 x 6.0 cm. With splayed crystals to 5 cm ending in broad, beveled terminations, this glassy aquamarine specimen is very dramatic for its size. The lustre is super, and glassy, all around. This would have come out in the late 1980s and was in the collection of Joel Bartsch, now curator and president of the Houston Museum of Natural Science. It was then in the Dave Stoudt collection.
6.9 x 5.9 x 3.9 cm. Two complete and relatively gemmy (for Erongo) crystals of aquamarine extend from the matrix 2.5 cm, crossing one another attractively. The fatter one extends down through the matrix and terminates underneath, and it is a very large 5 cm in actual length.
