5.1 x 1.7 x 1.3 cm. A very neat, vividly bi-colored emerald with a totally unique appearance to it. Complete-all-around. New find.
2.2 x 1.4 x 1 cm. A very fine, sharp, deep green emerald crystal perched amongst contrasting calcite. The emerald is 8 mm tall and extremely well-terminated. This has very deep color especially for a smaller crystal (small ones are usually more pale).
7.3 x 7.1 x 3.3 cm. This beautiful, display-sized specimen features a totally gemmy 1-cm-long emerald perched dramatically out of sparkling crystallized calcite matrix. A beautiful matrix emerald, and hard to get with such nice calcite as well. In fact, this is good simply as a calcite specimen for the locality.
3.3 x 3.0 x 2.5 cm. When it comes to Aquamarine, Pakistan is the most productive country for specimens in the last 20 years. Some of the very finest quality Aquamarine specimens come from the various pegmatites in the Pakistani Himalayas, especially the pieces from around Shigar. This locality has produced some of the most exciting Aquamarine specimens in recent years. A fine, sharp, lustrous, gemmy, soft blue color, stout, prismatic crystal of Aquamarine sits atop a mound of crystallized white Feldspar.
6.7 x 5.4 x 3.9 cm. This is a jewel-like, attractive combination specimen of schorl and aquamarine on ivory-colored feldspar. The lustrous, black schorls reach 2.25 cm across and the glassy and gemmy, intensely-colored aquamarines reach 2.1 cm in length. This specimen exhibits a pleasing sculptural form and has among the best glassy lustre and gemminess for the find. From the new find of late summer 2009.
12.9 x 10.5 x 10.5 cm. A massive, robust aquamarine crystal serves as the core of this specimen. It is completely crystallized, 360 degrees around, and very 3-dimensional. The crystal is glassier and more deeply colored than nearly all other Nagar aquamarines (which have a sad reputation for pale color, though some, like this, transcend). Overall this is the size of a small melon or a large grapefruit, very impactful and massive in presence compared to the more common, slender and elegant style for aquamarines from Pakistan. It is almost pristine. I obtained this after it was mined in 2007, directly from a source in Peshawar. Weighs 2.15 kilograms.
7.5 x 3.8 x 3.2 cm. This is a natural jewel, a complete 147-gram floater aquamarine crystal from one of the most famous finds for beryl on the planet, really almost a legendary find as everybody wants one but so few specimen-quality pieces survived the cutter wheels. It is a barrel-shaped, classic Jaqueto aquamarine crystal...the best ones are just like this, tapering on the ends and with a big robust gem nodule in the middle. This locality is not in Minas Gerais, but further north in Bahia, its own little deposit. This locality has produced some of the purest, most intense natural blue aquamarine for the gem trade in the past - and a few small pockets of specimens as well.
6 x 2.7 x 2.6 cm. This is a superb red beryl specimen. It is considered by many to be one of the finest and most unique American mineral specimens in existence. It was mined and sold directly to prominent collector F. John Barlow in the early 1990s (and is listed in his book, page 357, as the world's foremost example of the species). He had a core suite of 14 remarkable specimens of which this was the most important, and spent a fortune keeping on top of the finds here to have the best assemblage possible from this unique site. The locality is currently defunct but until recently was attracting the attention of gemstone giants like Tiffany's for its novel mineral. This particular piece is featured prominently in many media, including the F. John Barlow Collection Book, Lapis special issues on beryls, and probably any other work that references red beryl. Although it "disappeared" briefly and could not make the American Mineral Treasures exhibition in Tucson in 2008, it well should have been in that compendium case. However, the photo was still chosen as the lead specimen for the Red Beryl chapter of the companion book to that monumental exhibition, and is shown full-page on page 217 of American Mineral Treasures. The crystal is 2 inches.
26 x 17 x 13 cm. Unrepaired and a pristine floater complete-all-around. The morganite measures 8 x 8 x 3.25 cm and is the size of a hockey puck and as symmetrical as a crystal model. It is perfect, as if it were carved from pink ice. The color is a classic pink, not peachy-orange. The contrast of the pastel pink morganite and its sharp hexagonal form to the strangely tilting vertical spray of intense pink kunzites is, obviously, quite startling and exciting to see. It is one of the most 3-dimensional mineral specimens I could imagine. This is a world class gem pegmatite combination specimen.
27.5 x 18.5 x 17 cm. This remarkable piece dates to the 1960s heyday of Brazilian pegmatites, when spectacular pieces were found more frequently near the surface than they seem today. The piece is from a famous old deposit, which today produces beryls but nothing so impressive as what you see here. The matrix of cleavelandite is actually typical of this region, and quite nice in its own right. The morganite, though, has outstanding color, really a hot pink and a form more associated with modern material from Afghanistan than anything from Brazil. Most people would immediately peg this as an Afghani piece, I would bet (and in fact this has happened). However, the giveaways are the slightly different cleavelandite (more sharp and sparkly than Paprok material) and the coloration and style of the small tourmaline included in the morganite. The morganite itself is complete in about 95% of its display area, with only a small bit in one corner restored with matching epoxy. The morganite is very sharp, totally undamaged otherwise, and measures 4.5 inches (11.2 cm) across. Believe it or not, this piece came up from Brazil in the 1970s, in a suitcase, as a specimen that was triple this current size and mass at the time. A natural history collector purchased it from the Amsterdam Sauer Museum in Rio de Janiero in around 1976. This museum was both a display for the owner's well known personal collection and a storefront for selling specimens outright. Apparently, this collector simply put it on a coffee table where it sat, unappreciated by anybody in the core mineral community, for the next 30 years. After a tipoff, I bought the piece and had it trimmed down to its current, more aesthetic and balanced size. Still, at the weight of perhaps 20 pounds and the size of a decent watermelon, "trimmed down" has a whole different meaning here.
6.5 x 5.6 x 5.0 cm. A water-clear, 1.7 x 1.7 cm, gem aquamarine crystal with good color is aesthetically set amidst upright books of pearlescent muscovite on this fine combination specimen from recent finds at Nagar, Pakistan. The aquamarine has interesting beveled edges and is pristine. Classic, highly representative material from this noted locale. Ex. Duncan Elliott Collection.
11.6 x 2.0 x 1.7 cm. This aquamarine specimen is a wonderful gem quality specimen with crystal blue color and exceptional glassy luster. I would say that the crystal is about 80% water clear, with some highly unusual but distinct hexagonal growth patterns on one of the prism faces. These growth patterns also give the crystal somewhat of a skyscraper appearance where the lines resemble the floors of a tall building. Lastly, the piece has a much more dramatic termination than most aquamarine crystals (which usually have a flat basal pinacoid) as it shows both first order (2021) and second order (1121) prism faces. This crystal was once in the Gene Meieran collection, and was even sold by Evan Jones at one point.
5.5 x 2.7 x 2.5 cm. Gorgeous, sea-green beryl crystals of this amazing quality are very rare from the famous Teofilo Otoni area of Brazil. Specimens like this came out in the 1960s or early 1970s, with none since. Most went to Europe, Germany in particular, and were cut for the gem trade as this was before aquamarine could be had from Pakistan in more quantity. This superb gem is beautifully accented by cleavelandite rosettes on one side. The upper two-thirds of the crystal is cutter quality. The striking, etched/frosted side faces are fabulously complimented by the complex, pyramidal termination. Very nearly pristine. Overall it is a classic, highly desirable and very seldom available material from this noted locale.
2.4 x 2.1 x 1.6 cm. A sharp, lustrous, very sculptural cluster of intergrown goshenite crystals. Complete-all-around save a small contact in the back-bottom face of one crystal and quite 3-dimensionally dramatic in person.
3.4 x 2.7 x 2.3 cm. A sharp hexagonal crystal, complete-all-around and doubly-terminated, perched on just the right amount of matrix.
