6.8 x 2.0 x 1.7 cm. This is an ethereal aquamarine crystal that was once fat and normal, and now is heavily etched away by solution effects in situ, to this form. It is, in person, not as brown as it appears - iron /rust stuck inside is captured far too easily by the camera. In person it is overall a pleasing pastel blue. Weighs 23 grams.
VERY sharp crystal of red beryl, from the one and only place! It has excellent color. It is complete all around save only a hardly noticeable, very small divot of contact at one read termination corner. 1.4 x 0.5 x 0.4
4.9 x 2.6 x 2.3 cm. A strane, unusual, but very fine Erongo aquamarine crystal. This sharp, very glassy, hexagonal crystal is a pastel-blue, almost a goshenite beryl, on the outside, but the core of the crystal is a very intense blue. The pristine crystal is complete-all-around. The sidecar aquamarines and the tiny schorls embedded in the termination are nice accents. Ex. Charlie Key dealer stock.
4.4 x 0.4 x 0.4 cm. A gemmy, blue, doubly terminated, Colorado aquamarine crystal from the 1960s and the much less well-known Mt. White, near Mt. Antero. Ex. Doughty and Hauck Collections. Weighs 7.38 carats.
A beautiful blue, gemmy, etched and striated aquamarine crystal from Vietnam. It has an interesting, bubbly termination that shows signs of having once broken and then amazingly started to grow again . Very uncommon in this vivid color! This is the single largest crystal in a small lot of such beauties we got from a mining engineer who was over there. It is quite important for the locality, for the size, even if a little crude by Pakistani standards these days. 8.0 x 2.7 x 2.2 cm
9.6 x 1.8 x 1.7 cm. A stately, beautiful, long aquamarine crystal with excellent blue color from Nagar, Pakistan. The glassy crystal is gem-clear below the striking, multi-level termination and becomes translucent downward, typical of many Nagar aquamarines. This is a doubly terminated crystal with the other termination wreathed in bladed cleavelandite and embedded, tiny tourmalines. Weighs 48 grams. Ex. Mijer Collection.
7.2 x 7.2 x 4.4 cm. A fine and gemmy, 3.5 cm, peach-colored morganite elegantly set in pearlescent, bladed cleavelandite from recent finds in Afghanistan. The morganite has textbook crystal form. One photo shows two tiny sprays of needle aquamarine crystals near the morganite. Ex. Wayne Thompson.
1.8 x 0.9 x 0.9 cm. A unique, very rare, gemmy aquamarine from Bulgaria. This water-clear, ice-blue crystal is pristine and has vibrant color saturation. The complex, pyramidal termination is lightly etched. A textbook thumbnail aquamarine from a most unusual locale. Ex. Keith Williams. Keith exchanged this piece from the National Museum in Sophia on one of his trips to Bulgaria in 2004. He was told that the crystal was collected in the Rhodope Mountains prior to the 1930s.
5.3 x 0.8 x 0.6 cm. A gemmy and lustrous blue-green aquamarine crystal with an interesting, tapered termination from an uncommon Brazilian locality - the Mimoso do Sul Mine in Espirito Santo. These are rare and unique. Weighs 17.32 carats or nearly 3.5 grams. Ex. Jaime Bird Collection.
A pristine, very gemmy, lustrous and etched light-green heliodor from an EXTREMELY UNCOMMON gem locality, Hyderabad, India! Hyderabad was previously known only for quartz varieties but has recently produced some beryls. This is a significant crystal and has definite golden color - its not just a pale beryl by any means! 5.1 x 1.6 x 1.5 cm
10.1 x 8.5 x 6.5 cm. A pair of pale pink, translucent, somewhat lustrous, hexagonal Beryl (var: "Morganite") crystals sit atop a matrix of off-white blocky Albite (var "Cleavelandite") crystals. The largest Morganite crystal measures 3.3 cm across, and extends well into the matrix underneath. Ex. Kosnar Collection.
4.5 x 3.6 x 3.5 cm. A fine matrix specimen featuring a 1.0 x 0.7 x 0.6 cm emerald crystal beautifully perched atop a mounded matrix of calcite and shale with sparkly pyrite microcrystals. The gemmy and lustrous crystal is richly saturated, a deep emerald-green and is so transparently clean that you can look right through it. Note as an added bonus, that there is a tiny pyritohedron set on the side of the emerald and also a 3 mm emerald on the matrix. Ex. Saller Collection of Germany.
3.0 x 0.7 x 0.7 cm. A fine, old Russian aquamarine crystal from the Adun-Cholon Range of Russia. This classic, sharp and very gemmy crystal is notable for the symmetry of form, sharp termination and also the intense steel-blue color. The gem mines here started in 1723. This crystal probably dates to the Czarist Era, but no proof. Ex. Roland Sherman Collection. Weighs 11.74 carats.
8.8 x 8.0 x 7.4 cm. A large (6.5 cm across), transparent to translucent, very lustrous crystal of aquamarine, of tabular hexagonal form, dominates this rich aquamarine specimen. Three other crystals of similar form crowd around it. Tabular aquamarine crystals are rare, but some of the aquamarines from Mt. Xuebaoding are absolutely superb quality to boot. The color on this particular piece is a rich sky-blue.
5.0 x 3.8 x 3.2 cm. The classic locality of Val Vigezzo in Italy is one of the more unique localities in the European Alps. It's an interesting pegmatite locality that is most well known for its Emerald specimens, but it also produces Zeolites, metallic oxides and even rare-earth species. This piece is a classic Val Vigezzo Emerald featuring prismatic, light green, hexagonal crystals measuring up to 11 mm on matrix. Ex. Brian Kosnar Collection.
