4.1 x 1.2 x 1.2 cm. A classic and fine polychrome tourmaline from recent finds at the Pederneira Mine. This gemmy and lustrous crystal grades upward from cranberry-red at the base to pleasing pink to near colorless to teal-blue to green at the strangely etched, steep, three-sided, pyramidal termination. The lavender lepidolites and little sidecar crystal at the base are nice accents. Complete-all-around and nearly pristine.
8.0 x 4.8 x 3.7 cm. A 4.7 cm, pristine, gorgeous, gemmy and lustrous, bi-colored tourmaline is very aesthetically attached to the side of two, intergrown quartz crystals from Darra-i-Pech, Afghanistan. The tourmaline body is a beautiful, vivid pink and both ends are very complimentary, multi-hued green. The glassy, primary quartz crystal is complete-all-around, though contacted on one side. The smaller quartz crystal is complete in the front and back is cleaved.
5.7 x 2.4 x 2.3 cm. A riveting, incredibly intensely colored tourmaline with a deep green base shading to deep blue indicolite color at the top. The piece is extremely three-dimensional and just superb.
6.2 x 1.7 x 1.7 cm. This doubly terminated indicolite has a transparent, almost neon-blue, zone in the upper 1/3 of the crystal. One of only 3 crystals I saw from a strange new pocket, found in September 2006.
3.8 x 1.7 x 1.2 cm. This is a doubly-terminated indicolite with a transparent, neon blue-upper section. The termination is sharply defined in this specimen. It is very gemmy, though also rather skinny. One of only 3 crystals I saw from this strange a pocket, found in September 2006.
3.5 x 2.1 x 1.9 cm. In the early to mid 1990’s, a pocket of amazing sceptered elbaites was discovered with etched pink bases and rich green terminations. This is one of the better miniatures from that find. The color contrast along with the sceptering makes this a choice elbaite. Most such specimens also had weaker green caps so this one is pretty...the contrast leaps out at you. It is not subtle as with some of the specimens of more slender aspect from the pocket. Ex. John and Linda Stimson Collection.
2.6 x 1.4 x 0.9 cm. A beautiful, gemmy and lustrous, rich green, flattened tourmaline crystal with a lustrous, very dark green to black, pyramidal termination. This thumbnail piece has very nice composition with the sidecar crystal. From a very uncommon Pakistan locale - Chhappu in the Braldu Valley. Ex. Allan Young Thumbnail Collection. Weighs 6 grams.
4.5 x 2 x 2 cm. Parallel growth, bi-colored crystals of lustrous and translucent elbaite have coalesced into a single crystal with multiple terminations. The color is pastel, not the most intense, but it’s a nice single crystal cluster from here, representative of this color-style and habit which is unique to Stak Nala. Weighs 30 grams.
3.75 x 1.5 x 1.5 cm. This 27-gram, color zoned elbaite crystal is the classic "watermelon" mix where the core of the crystal is pinkish-red and the edges are a pastel greenish-blue. In spite of internal crazing, the crystal is glassy and gemmy. Note there is edge damage, shallow but present, all around the muted termination.
4.6 x 4.1 X4.1 cm. A historic, old-time, polychrome tourmaline with cleavelandite from the Stewart Mine. The highly lustrous, well-striated crystal is moderately translucent. The body is green, with both the glassy termination and base being a rich purple. The crystal is beautifully accented with pink highlights. The complete-all-around crystal is nicely complimented with bladed cleavelandite. The tourmaline is nearly pristine. The piece has a long hisory and excellent provenance. The piece was collected by the American Musuem of Natural History in New York City in the early 1900s. It was de-accessed in 1950 to Robert Hesse and later became part of Bill Larson’s Pala International San Diego County Collection.
4.4 x 2.3 x1.9 cm. A really fine cluster of two stacked, polychrome tourmalines from the 1980s finds at Stak Nala, Pakistan. The upper, doubly terminated tourmaline is strikingly embedded in the termination of the lower crystal. The gemmy and lustrous crystals have classic, highly desirable, pink terminations with multi-hued, green bodies. A sharp, glassy, quartz crystal and cleavelandite blade are superb accents to this piece. A beautiful and aesthetic Stak Nala tourmaline combination specimen.
9.3 x 3.4 x 2.5 cm. Incredible glowing blue color in a large and translucent tourmaline. This is also complete, 3-D, all around. Ex. Wally Mann Collection.
6.0 x 3.2 x 3.0 cm. In recent years the Malkhan pegmatites have produced many translucent, to opaque, deep red elbaites. However, this translucent crystal abounds with unusual colors like golden amber, hints of golden green, along with the traditional rose-red highlights. The red hue is more visible down the c axis while the lighter colors show up best when viewed from the side. Very lovely and unusual.
23.2 x 3.6 x 2.3 cm. This specimen has no repairs. Most people today associate the Jonas Mine only with the single most famous find here of deep pink tourmaline. However, the mine also produced green tourmaline of high caliber and size. This crystal is a huge single, with sharp termination and excellent form. Note the dramatic surface tone of green, translucent to just a millimeter or so inside, which gives the piece a rippling silky look on the surface. When strongly backlit, it is greener internally as well, and translucent in some parts.
5.1 x 4.1 x 3.5 cm. This is a geometrically complex, castle-like tourmaline whose shape is the product of intricate natural etching or dissolution effects acting upon the original tourmaline crystal. While common in spodumenes and kunzites, this effect is much less often seen in tourmalines. The piece is 3-dimensional and complete-all-around, except for some contact on the lower periphery of the backside. It is the most massive of the three good specimens I saw at the Munich 2009 show. The shape and complexity is really mesmerizing, and quite different than other tourmalines you commonly see except for a certain resemblance in style to a few pockets from the Barra da Salinas Mine (famous for its etched scepters). Nevertheless, the color here is what takes this pocket to another level of uniqueness. They are an intense candy-red in color. These are more colorful even than the Jonas mine rubellites, which most of us consider to be the finest red rubellites known for purity of color. Only 4 specimens were available at the Munich Show, from what is reputed to be this very small pocket found in October of 2009.
