7.8 x 4.4 x 2.9 cm. This is a very freestanding, glassy and very gemmy tabular aquamarine crystal on matrix, measuring 3.5 cm across. It has just the slightest touch of blue to it, or it would be called a beryl. There are some smaller aquamarines on the matrix as well, scattered amongst the bladed muscovite.
3.3 x 2.4 x 1.5 cm. Here you have a schorl crystal with wonderful rounded form that makes it look almost more like a garnet - and out of the top of it sticks a gemmy, terminated aquamarine crystal.
2.3 x 0.9 x 0.8 cm. A gemmy crystal of aquamarine, terminated, lustrous and complete, from Erongo. A little crystal of schorl adds an accent at the base.
6.7 x 0.7 x 0.7 cm. A fine aquamarine gem crystal for Nigeria, very gemmy, with a silky luster, a sharp termination and sharp prismatic faces as well. It is quite transparent, but the camera picked up the silky surface luster, which is what makes it look cloudy - there is also a slight blue color that does not appear in the photo. The crystal tapers in right at the top due to a natural contact. Weighs 9 grams.
5.2 x 3.9 x 3.2 cm. This large aquamarine crystal is absolutely glass-clear inside, and if you look through the glassy "window" in the termination (surrounded by frosty faces) you see several centimeters down to the natural "garden" inside. This is a very chunky and sizeable crystal, weighing a healthy 100 grams.
3.4 x 1.6 x 1.3 cm. Super gemmy for the Erongo locality: a 13-gram crystal of aquamarine, finely-terminated, with a couple of sidecar crystals and a few little attached crystals of schorl.
3.1 x 1.3 x 0.6 cm. A gorgeous, gemmy and lustrous, doubly terminated emerald crystal from the much less well-known Polveros Mine of Colombia. This pristine beauty has excellent clarity, light green color saturation and is nicely accented with calcite and shale. 15.17 carats or just over 3 grams.
5.4 x 3.4 x 3.2 cm. Tabular, glassy and gemmy, pastel blue, aquamarine crystals, to 3.25 cm across, are perched on pearlescent muscovite, to 1.0 cm across. Ex. Carnegie Museum Collection.
2.6 x 0.5 x 0.5 cm (largest). These are 4 loose crystals of glassy and gemmy, pastel blue, aquamarine, to 2.5 cm in length. Ex. Carnegie Museum Collection.
5.9 x 5.9 x 4.2 cm. A complete, large, uncontacted and undamaged, gemmy crystal of morganite on matrix. This light pastel-pink crystal measures 4.8 cm across, and is a beefy 2 cm thick. It is highly transparent through the center. The crystal is cupped in a perfect setting of stark white, bladed cleavelandite.
6.2 x 6.1 x 5.3 cm. A superb, sharp, gemmy and lustrous, 2.8 cm, hot-pink morganite crystal very aesthetically set in unusually pearlescent matrix from Peech, Afghanistan.
8.1 x 2.7 x 2.3 cm. A lovely etched Beryl (var: "Aquamarine") crystal from the Pakistani Himalayas with a soft blue color and a cool rounded (not jagged) form. The crystal is water clear in areas, and would certainly yield several fine gemstones. Ex. Richard Kosnar Collection.
2.8 x 2.8 x 2.2 cm. Surreal, gemmy and lustrous, parallel-growth, green-blue emerald crystals with glassy, colorless magnesite rhombs from a new find at Brumado, Brazil.
6.9 x 6.4 x 4.9 cm. This is a cluster of large, tabular crystals, with very light blue-grey color and glassy luster. They are highly transparent. The two large crystals measure about 3.5 x 3 centimeters. The euhedral feldspar adds an attractive accent.
5.2 x 3.3 x 1.9 cm. A fine miniature with a very unusual look for a Pakistani combo piece. The focus is this super-gemmy, 4.5-cm aquamarine crystal - actually two crystals grown closely together. Both are glassy, complete and terminated, and even more transparent-looking in person. But the unusual thing that really adds to the aesthetic quality of this piece is the little schorl tourmalines that decorate the quartz crystals the form the matrix for the specimen, contrasting strikingly with the aquamarine and the milky quartz.
