11.4 x 9.2 x 6.2 cm. This is a sharp tabular aquamarine crystal of this style that measures 10 cm from side-to-side. And for its size, it is actually fairly gemmy as well. What is more, the crystal is complete and undamaged. It has natural etching on its front and back faces. The aquamarine is thick too, measuring 2.5 cm thick. There are two generations of attractive muscovite crystals decorating the side of the aquamarine (smaller crystals growing on the large ones).
7.7 x 4.6 x 3.5 cm. Beryl specimen from Topsham, Maine, The 6.7 cm, hexagonal, lustrous, translucent, pastel-green beryl crystal is attached to quartz matrix. Both ends of the beryl are contacted. Ex. Dennis Mullane Collection and accompanied by a faded, handwritten label.
10.3 x 4.3 x 2.6 cm. A very intense blue aquamarine that I have to admit, because of its intensity of color and its unusually tourmaline-like termination (not hexagonal, but beveled and more prismatic in appearance), could be confused as a tourmaline at first glance. This piece is beautiful, and complete all around. 173 grams. From a new find of August 2008.
4.4 x 4.2 x 3.0 cm. From a famous find of 2005, this is one of the "ice sculptures", or freeform aquamarines, found in several large kaolinite clay pockets. Intense blue color and internal brilliance characterize this find. 49 grams.
13.7 x 5.7 x 4.8 cm. A huge, 1.5 kilogram matrix emerald from this classic emerald district in Brazil. Crystals reach 6 cm, though the big one to the right is incomplete. The top crystals are terminated, if roughly. Seldom do you get such nice large specimens out of this mine, with any kind of contrast between a cluster of emeralds and white matrix.
2.9 x 2.9 x 2.7 cm. An intense blue aquamarine with a fascinating termination. From old finds here. Weighs 33 grams.
7.6 x 2.3 x 1.7 cm. A 54 gram crystal of aquamarine with an interesting surface patterned by dissolution it started to undergo in the pocket, as if melting. But, it retains a termination and is not etched into "gem shards" yet, making it caught in the process.
3.3 x 1.0 x 0.8 cm. This is a bullet-shaped aquamarine, of cutting grade quality, from famous old finds at the Jos Plateau gem district. Superb color, beautiful, icicle-like form. Ex. Charlie Key.
2.8 x 1.6 x 0.7 cm. A pure gem crystal of light golden-yellow heliodor beryl, with a silky luster, from Brazil. Slight shallow contact on one side. Wonderful form and termination. Weighs 5 grams. Ex. Jaime Bird Collection.
5.9 x 3.9 x 3.4 cm. A cluster of gemmy, lustrous crystals of aquamarine (to 4 cm in length), with all terminations intact. The crystals are wonderfully accented by blooms of bladed muscovite. Ex. Jaime Bird Collection.
6.8 x 6.0 x 3.4 cm. A very rare sceptre of aquamarine on matrix. This 2-cm crystal has a silky stalk with transparent, terminated "cap" on top. It has grown up amongst blocky crystals of snow-white albite. Ex. Wayne Thompson Collection.
4.1 x 0.9 x 0.8 cm. A gemmy, terminated crystal of aquamarine from this classic locality.
3.7 x 3.2 x 3.2 cm. An exquisite, extremely aesthetic aquamarine crystal cluster beautifully set between two, lightly etched feldspar crystals from recent finds at the Erongo Mountains of Namibia. The pristine aquamarines are exceptionally gemmy and have excellent blue color, for the locale. The striking, central crystal is 3.1 cm.
2.1 x 1.3 x 1.2 cm. A bright, transparent-to-translucent, sizeable emerald crystal from the great emerald locality of Muzo. The crystal is complete all around, and terminated, with a slight bit of edge wear. In person, slightly less blue and more to the green. Weighs 6 grams. Ex. Jaime Bird Collection.
6.2 x 2.4 x 1.6 cm. A very aesthetic, fine specimen of aquamarine from Erongo. The crystals are quite gemmy for the locality, particularly at the terminations, which are water-clear (also glassy on the surface and beautifully formed). All the terminations and side-crystals here are intact.
