8.4 x 1.1 x 0.8 cm. A beautiful, gemmy and lustrous, green tourmaline with a very distinctive, steeply sloping, black, pyramidal termination. Classic material from the Pederneira Mine of Brazil.
4.8 x 1.0 x 0.9 cm. A beautiful, gemmy and lustrous, parallel-growth, "red-tip", polychrome tourmaline from the Cruzeiro Mine. The translucent, cranberry-red, pyramidal and pinacoidal termination grades downward to a very gemmy, blue-gray-green at the base. This crystal is exceptional, in that the cranberry-red extends much further down the crystal than usually seen. It is complete-all-around and pristine. This is classic, old, 1960s-1970s material from this renowned locale. Ex. Steve Smale Collection. Weighs 10 grams.
8.7 x 1.3 x 1.0 cm. A pristine, gemmy and lustrous, gradational emerald-green tourmaline crystal with a steep, black pyramidal termination from recent finds at the Pederneira Mine. The green color saturation subtly intensifies from the base, up to the termination.
4.1 x 1.3 x 1.2 cm. A beautiful, gemmy and lustrous, pink tourmaline with a cranberry-red, pyramidal termination area from the Cruzeiro Mine of Brazil. There are even gemmy flashes of yellow-green on the very top of the termination. This is old-time material from the 1960s or 1970s and is from the Steve Smale Collection. Weighs 15 grams.
5.2 x 1.4 x 1.1 cm. A beautiful, gemmy and lustrous, bi-colored, sceptered green tourmaline with a pink base and striking pyramidal termination with intriguing etched faces. There is even a hint of teal-blue in the termination. This fine, uncommon and older crystal is from the Barra de Salinas pegmatites of Brazil and the Steve Smale Collection. Pristine and complete-all-around. Weighs 11 grams.
4.5 x 3.9 x 2.9 cm. A beautiful tourmaline and quartz specimen from Peech, Afghanistan. Three gemmy and lustrous pastel-pink to pastel-green to teal-blue tourmalines to 3.5 cm are perched on the side of a sharp, pristine, complete all-around quartz crystal with frosted and skeletal termination faces.
9.2 x 3.4 x 1.8 cm. A beautiful, very interesting Pederneira watermelon tourmaline. Most of the specimen is a very pleasing teal-blue, with a cranberry core at the base and olive-green at the termination. The jagged termination is heavily etched on one side and the sideways crystal looks like a bullet impaled in the side of the tourmaline body. A very unusual and fascinating Pederneira tourmaline, that is essentially pristine. The lower, fractured, bent, sidecar crystal has a broken, but healed termination.
4.1 x 1.4 x 0.8 cm. A fine, doubly terminated, gemmy, lustrous and pristine bi-colored tourmaline from Peech, Afghanistan. The pink, pyramidal termination grades downward to pleasing apple-green to a pinacoidal termination with a pink core. The sidecar crystal and part of the main crystal are interestingly clothed in off-white lepidolite microcrystals.
9.3 x 4.4 x 3.3 cm. This is a bizarre tourmaline from some unusual finds in the late 1980s. It is "hairy" for lack of a better word, with a normal, typical, dark green body that suddenly transforms into a hair-like nest of acicular crystals atop. I should not use the word nest, though, because this implies disorder - the crystals are acicular and discrete. They do shoot up vertically on the correct crystal axis. It is just that the fibers did not merge, somehow, to form a normal termination encompassing all of them. This is one of the biggest of the group as I recall seeing them. I obtained bought the piece from Frank and Wendy Melanson in the late 1980s at the Cincinnati show. I sold it in the 1990s and never forgot it. Ex. Rob Lavinsky Collection.
9.4 x 8.5 x 5.1 cm. This stunning gem crystal measures 6.5 cm tall, 7 mm wide, and looks like it is impaled into the matrix. It is more vibrant; more vividly colored an electric evergreen-green color in person. From the Saller gem collection, in southern Germany.
4.5 x 4.1 x 1.9 cm. A very sculptural and aesthetic, two-crystal tourmaline specimen from recent finds at the Pederniera Mine. The bodies of the gemmy and lustrous crystals are a beautiful, variable, teal-blue and green. The unretouched backlit photo highlights the cranberry-red core of the lower part of the main crystal. The lustrous termination of the upright crystal is broken, but healed, and has a really interesting tourmaline "bill" projecting off of one edge. The backside of the upright crystal is contacted, but has no damage, per se and is highlighted by a thin sheet of cleavelandite and two small clusters of pink lepidolite. The termination on the secondary crystal is broken.
2.5 x 2.4 x 2.1 cm. A fine, sceptered tourmaline thumbnail from Afghanistan. A 1.8 cm, gemmy and lustrous polychrome tourmaline is attached to quartz matrix. The rose-red base grades upward to pink and is "capped" by the incredible, indicolite termination.
3.3 x 2.5 x 2.2 cm. Madagascar has produced some attractive Tourmaline specimens over the years. These specimens seem to be dwindling fast, due to political upheaval combined with the fact that the pegmatites which produce these specimens are running dry according to Dr. Federico Pezzotta, who collected this specimen personally in Madagascar. It features a lovely, translucent, cranberry color "Rubellite" crystal perched atop additional "Rubellite" with minor Smoky Quartz.
This is not only a CONNECTICUT tourmaline very uncommon on the market, but a FINE one at that! It is gemmy from top to bottom, terminated, lustrous, and a fine grass-green color! Ex. David Seaman collection. It is not just rare, but pretty besides. unlike most Gilette pieces, it is pristine and not repaired! 3.6 x 0.7 x 0.5 cm
An extremely pretty 1.6-cm crystal, gemmy, bi-colored and terminated, is the star of this specimen, with several other crystals scattered on the matrix, and a sprinkling of lepidolite which adds a pleasing lavender color accent. 7 x 4 x 2.5 cm
