Unfortunately the pic is angled so that it emphasizes a whitish area at the bottom of the crystal, but in fact, this is a really good red beryl, measuring a full centimeter in length, with deep color and lustrous faces, well-exposed on the matrix. These matrix red beryls are just incredibly hard to get now at anything but absurd prices on teh open market. 4.5 x 4.1 x 3.9 cm
4.7 x 4.5 x 4.3 cm. This intense green emerald is 2.3 cm long, 1.5 cm wide, and glows with color. Not only is it on matrix, or calcite matrix, but it is on crystallized calcite matrix. The calcite crystal atop is about 1 inch across. It makes a great contrast in color and crystal form to the emerald. The emerald is typical in overall hexagonal habit, but atypical in that the surface is minutely detailed, as if somebody took a scribe tool and inlaid a complex cityscape on its surface. The result of this complexity on the apparently smooth outer faces is that the emerald is much more sparkly than you would expect, with all those microfacets reflecting light.
13.9 x 6.0 x 3.4 cm. This nearly 300-gram mass of intergrown emeralds is a very significant locality specimen simply for the size and color impact of having so much pure emerald in one place. It has really rich, deep green color, unusually good for this Brazilian material, actually. These are chemically or physically removed from surrounding matrix, and this piece probably had a top layer of calcite removed, and was contacted to schist on the bottom (its backside, on which schist still remains).
3 x 2.9 x 1.4 cm. A superb doubly-terminated 3 cm Aquamarine perched perfectly on a matrix of Schorl crystals and smaller Aquamarines. The main Aquamarine is lustrous and perfectly-terminated, with each termination having 2-3 mm of totally gem-clear crystal. The architecture is reminiscent of the great piece on the cover of the May, 2007 Rocks & Minerals. Ex. Charlie Key.
8 x 6 x 4 cm. This is a fine matrix piece of superb Aquamarines with gemmy lustre and intense Erongo-blue color. They stand upright and stark against a matrix of partially etched Orthoclase, capped in places by highly fluorescent Hyalite Opal overgrowth. The Aquamarines are terrific - excellent color and luster, gemmy terminations, and the largest is 5 cm tall. The termination, on its right side, shows a secondary growth: a thin layer of slightly different colored aquamarine atop the main core. Ex. Charlie Key.
4 x 3.6 x 3.4 cm. An incredible and robust Aquamarine from the Erongo Region of Namibia. This amazing crystal is 4.1 cm tall and 3.6 cm across. The color is excellent, the luster on the termination is superb, and the upper 1.6 cm of the crystal is almost perfectly gemmy (unusual for the locale). The attached small (up to .3 cm) Schorls are equally well-formed and lustrous. At 111 grams, this is a stunning miniature. Ex. Charlie Key.
11 x 8 x 7.5 cm. An exceptional, artistic combination of Aquamarine, Smoky Quartz, and Schorl from the Erongo Mountains. Rarely do you find these three in combination, and when you do, they are hardly ever in this quality. The Aquamarines are superb: excellent deep to light blue color, gemmy terminations, and glassy luster (faces and terminations). The largest of the Smoky Quartzes is 6.6 cm, and doubly terminated. They are translucent and elegantly tapered. The Schorls add wonderful contrast, and they have excellent to slightly etched luster. Ex. Charlie Key.
3.8 x 3.7 x 2.7 cm. Numerous crystals of glassy goshenite, to 1.6 cm, are perched suspended in a maze of jet black schorl on this unique and sculptural specimen. In person, it is very bright, aesthetic, and appealing for its complexity. Complete-all-around; on the backside more schorl and less goshenite, but they are sharp and isolated.
2.6 x 1.6 x 1.3 cm. A sharp, doubly-terminated floater crystal, complete-all-around…somewhat better in person; and hard to convey in photos, how nice and glassy and bright this is.
8 x 5.1 x 1.8 cm, A rich plate thickly covered with glassy, lustrous, gemmy crystals to a 2.1 cm, some of them doubly-terminated, on muscovite matrix. This is a very beautiful, sparkly, gemmy piece.
6.8 x 5 x 4.6 cm. Isolated, glassy, lustrous, gemmy crystals to 1.6 cm on muscovite matrix. Minor schorl association provides a nice contrast.
9.8 x 3.8 x 3.1 cm. A sharp, lustrous, glassy 1.5cm barrel-like crystal perched on the side of a complete quartz point – unique. This looks like apatite, it is so sharply hexagonal and gemmy and lustrous - it is a very surprising occurrence for goshenite.
This is a doubly terminated,barrel shaped crystal of rare TRULY GOLDEN color unlike most so-called greenish heliodor. The color is a bright YELLOW and is extremely gemmy as you see. There is some evidence that this specimen also underwent etching and both terminations show signs of breaking and natural rehealing in the pocket. Although the back faces are broken, it displays well from the front . Although I am a mineral purist, a HUGE stone could be cut from this piece as it is almost entirely of lapidary and gem quality inside RARE material mined in the 60s from Green Walking Stick Mine, Karoi, Zimbabwe 3.7 x 2.9 x 2.9 cm
11.8 x 7.1 x 4.1 cm. A rich plate thickly covered with glassy, lustrous, gemmy crystals to 2.5 cm, some of them doubly terminated, on muscovite matrix. This is the largest good specimen of the pocket that I know of.
A REALLY deeply-colored, gemmy, forest-green emerald crystal, 9 x 7 x 6 mm in size, embedded in contrasting calcite matrix. The crystal is 9mm tall and is mostly transparent. The quality is very high because of the EXCELLENT forest-green color and clarity, as compared to many such specimens. Also, its legit - guaranteed not to be "helped" in any way (the Columbians call it "stabilizing" when they glue loose xls into matrix!) 5.5 x 4.5 x 4 cm
