GEM: 6 x 4 x 4 mm and 1.35 carats
A matrix specimen featuring an extremely fine small crystal of this classic deep blue, unheated, natural indicolite that once set the standard for blue hue in gem tourmalines. I am told these came out befor eBrazilian indicolite was common, and still set the standard for a"pure" blue. Faceted stones go for $300-500 per carat and this rough and cut set is of top quality (the crystal could be easily cut, itself). Includes a matching cut stone from the same rare old material.
Deep blue gem crystal of indicolite from this rare California location, with a slight green tip. This crystal is beautiful with rich color and a nice glassy luster. A VERY RARE and must-have California specimen from a small pocket at an extremely small and hard-to-get locality. I personally obtained this from Tim Sherburn, a San Diego collector who himself had obtained it directly from John Sinkankas. Ex John Sinkankas (self-collected in 1956) and Kevin Brown collections. NOTE: HAS SINKANKAS LABEL
Unique blue-capped tourmaline from one of the newer California pegmatites. Collected in April 2001, this tourmaline was purchased prior to the lot being shown around. The crystal is still the only good blue-cap I’ve seen from the location. The body of the crystal is a nice pink color, gemmy in a few areas, with the termination being blue. The cap has been reinforced, not repaired. Roland Reed Mined it, sold it to Cal Graeber, who sold it to Kevin all within days of it being found. Ex. Kevin Brown collection.
This tourmaline is the second of three rare Connecticut specimens in this collection. This crystal is an indicolite from a small, much lesser known location. Beautifully colored, the crystal has a sharp termination and is actually gemmy. A very rare and important east coast tourmaline specimen. Ex. Ed Boucher and Kevin Brown collections.
Rare locality tourmaline from one of the hardest to find California locations. This brightly colored blue crystal is gemmy throughout with slight shading to a greenish/blue near the termination. The crystal is simply huge for the location and the largest I�ve seen available out of all the California collections I have handled. Ex. Chuck Houser and Kevin Brown collections. Chuck obtained it directly when found, in the early 1980s.
Another very difficult to find tourmaline from Southern California is this specimen from the Cota mine. The only elbaite I’ve seen available from this mine, the piece came out prior to 1975. The crystal has a rich dark olive green color with one of the sharpest and most unique terminations possible on a tourmaline. Ex. Ed Ruggiero and Kevin Brown collections.
Interesting and suprisingly colorful crystal from a very uncommon location in Massachusetts. The crystal has a dark blue color and glassy luster. It is translucent in part, but not transparent at all. A couple very small abrasions are present along the back of the termination. This specimen is the only crystal I’ve ever seen for sale from this rare New England location. Ex. Kevin Brown and George Elling collections.
An unusual elbaite. Both the blue and the pink are deeply colored and unusual shades to find in combination with each other. This cluster is also pristine, and complete all around as you can see here. 11 x 6.0 x 4.2 cm
This important old tourmaline is a classic of the 1960s finds here, showing a vibrant hue that is unique to this day. I can recognize a Virgem de Lapa of this style anywwhere on sight, it is so unusual...in person, the hue will probably better come across, though. It is somehwere between lavender and maroon, with perhaps alternating shimmers in different lighting but going more lavender in strong light, i'd say. This is a rather large and rather gemmy crystal, which Ed traded from Keith Proctor's collection over 20 years ago. It then sold to me in a cull at some time in the 1990s, went to a collection in Australia, came back to me, resold to Ed, and is now back with me for a third time in the funny way things go round. Comes with custom base. 11.9 x 3.1 x 2.9 cm
A RICH, JUICY, PINK elbaite from a pocket hit in 1998. 14 x 8 x 7 cm
6.1 x 1.7 x 1.6 cm. Look at the amazing COLOR of this Namibian tourmaline crystal, from the collection of Willy Israel! It features an amazing blend of teal and green tones under good light. The crystal is complete all around, and has fine luster. It has a complete termination of complex form (though with a rough surface, which is common from this locality). Weighs 32 grams. Blue tourmaline of this quality from the locality is extremely uncommon and this is a good piece.
4.8 x 0.6 x 0.5 cm. A bottle-green gem crystal of tourmaline from the Pederneira Mine. It is doubly-terminated, though the bottom termination is rough. The crystal has a strange "tube" running right through its middle! Weighs 3 grams.
4.3 x 0.9 x 0.8 cm. Gemmy from top to bottom -- a fabulous Jos tourmaline, grading from pink at the bottom, to a bright grass green, to dark green at the termination. Roughly terminated on the bottom as well (with a few chips). Complete all around, fine luster, no damage - a fine representative tourmaline for this locality. Weighs 8 grams. Ex. George Elling Collection, with an old Eugene Sensel label.
3.4 x 0.6 x 0.6 cm. Not terminated, but top gem from top to bottom, pretty bright light green color.
3.2 x 2.6 x 1.7 cm. Green tourmaline with a frosted black termination and black core. This gemmy and lustrous beauty is nicely accented with elbaite and comes from the E.R. Chadbourne (D. 1908, Lewiston, ME) and Phil Scalisi Collections. 23 grams.
