2.6 x 0.5 x 0.4 cm. A very gemmy thumbnail crystal of gem aquamarine, terminated and complete, with glassy luster and a couple of attractive sidecar crystals.
2.6 x 0.4 x 0.3 cm. This little aquamarine crystal is distinguished by having a rare tapered form, from natural etching by corrosive solutions in the pocket. The crystal is complete - those are the natural pointy terminations.
8.7 x 2.5 x 2.2 cm. This is a fine aquamarine floater crystal, with just the slightest hint of blue to it. The faces are naturally etched, giving it a frosty look. One termination is glassy the other is frosty like the rest of the crystal. There is a strange frothy-looking "tube" running down through the center of the crystal. This impressive crystal weighs in at 110 grams.
6.6 x 6.3 x 4.6 cm. A superb cluster of six doubly-terminated Aquamarine crystals intergrown with Orthoclase and a beautiful lustrous Schorl crystal. The largest of the aquamarines is 4 cm long, has excellent luster and sky blue color, and a clear gemmy .5 cm termination. Ex. Charlie Key.
5 x 4.5 x 2 cm. An attractive Aquamarine "cross" consisting primarily of two large crystals. The largest, which 5 cm long, has a 1 cm gemmy main termination and multiple gemmy terminations at the base. The second crystal also has multiple terminations. The luster is excellent, and the color very good. Ex. Charlie Key.
3.7 x 1.8 x 1.4 cm. A beautiful, lustrous, blue Aquamarine from the Erongos. The termination is two generations, the first being beveled and frosted, and the second being flat and super smooth. Ex. Charlie Key.
5.5 x 4.8 x 3.1 cm. A really complex combination piece, with an aquamarine shooting straight up through the crystallized albite feldpsar matrix (you can see it extend from underneath) like a fiber-optic cable of gem blue glass that transmits light from below if you shine it up. On this aquamarine is perched, as a wraparound, a spessartine garnet crystal that is pretty good on its own merits; plus the bonus that it is set up like a flag above the sharply crystallized white background. The terminated zigzag schorl at the base is a final bonus. Ex. Helmut Bruckner Collection.
7.9 x 7.5 x 5.9 cm. A large, rich cluster of fine, sharp aquamarine crystals and jet-black schorls, from the Erongo Mountains. All terminations are complete. The largest of the aquamarines, 3 of them, measure around 2.5 cm in length. They have a fine balance with the schorls, and both sit on a nicely contrasting tuft of stark white matrix. Ex. Marshall Sussman Collection.
4.3 x 2.4 x 2.4 cm. A crystal of glass-clear gem goshenite (colorless beryl) that was naturally etched by corrosive solutions in the pocket, leaving this weird form. The crystal is so clear that it really does look like a shard of glass. Weighs 29 grams. Ex. Richard Hauck Collection.
5.9 x 4.2 x 2.9 cm. A stacked row of four super-gemmy, glassy, tabular aquamarine crystals, to just under 3 cm, from Pingwu. Albite crystals add a pretty accent.
12.4 x 6.8 x 3.8 cm. This aquamarine crystal is just huge for China. It is from a new find in the prolific Wenshan locality. It is mostly translucent, with some transparent areas - it is very sharp and lustrous. There are some pretty accenting muscovite and albite clusters attached. Crystal is 12 cm long.
2.3 x 0.7 x 0.7 cm. A fine aquamarine with a very gemmy end and perfect termination, with some tiny acicular schorl crystals embedded in the termination.
3.5 x 3.5 x 1.8 cm. A fine, opposing two crystal cluster of gemmy and lustrous aquamarine crystals from recent finds at the Erongo Mountains of Namibia. The aquamarines are nicely accented by feldspar and as is typical with many Erongo aquamarines, the terminations areas are extremely gemmy.
2.2 x 1.2 x 0.8 cm. A water-clear, gemmy and lustrous, doubly terminated, faint blue-green aquamarine crystal from the Pack Rat Mine, Jacumba District, San Diego County. The crystal has a distinctive interior refraction in the middle and the terminations are lightly coated with iron oxides. Ex. Irv Brown Collection. 22.6 carats or 4.5 grams.
5.0 x 4.8 x 2.9 cm. A classic, superb emerald specimen from the famous emerald mines of the Ural Mountains of Russia. This very aesthetic pair of fat translucent crystals, set in biotite schist, has excellent, rich green color saturation. The fat, well-terminated crystal has exceptional gemminess in the upper half, for the locality.
