4.3 x 1.4 x 1.1 cm. A fine gem tourmaline with intense scarlet color, out of the collection of Steve Smale. It is complete, uncontacted and wonderfully terminated. The crystal is very gemmy, particularly through the bottom half, where the color grades to a light teal. Fine luster, too. Weighs 13 grams.
4.1 x 1.7 x 1.5 cm. A super GEM tourmaline, with gorgeous green color at the bottom and an intense magenta cap! The termination is textbook, with no damage (a few tiny, shallow natural etch pits on one termination face). Complete all around, uncontacted and undamaged. Beautiful distinct pocket from about 5 years ago produced these.
3.4 x 0.8 x 0.8 cm. A cutter-quality gem tourmaline from the Pederneira, pure gem from top to bottom, nicely terminated and with good luster. Not a big crystal, but fine. Weighs 3 grams.
Thumbnail-Miniature. This was someone’s private collection of tourmaline crystals from the Himalaya Mine. Most of them are gemmy, and each has a complete termination. They range from green, to pink, to a combination of the two hues - with a couple of schorls thrown in. With the exception of a blue-cap, you can see pretty much the whole Himalaya gamut here!
3.4 x 0.8 x 0.8 cm. A perfect, pristine gem tourmaline crystal out of the collection of Steve Smale, from the Benedito Mine in Minas Gerais. It is glass-clear and flawless, with a fine termination and superb luster - bottle-green, very close to Bolivian vivianite in color. Weighs 5 grams.
4.9 x 1.4 x 1.1 cm. A super-gemmy, very fine tourmaline crystal with a stunning cranberry color and scarlet termination, from Brazil. The luster is glassy. The termination is complete and undamaged - those are natural little etch pits you see in the pics. Complete all around, uncontacted and undamaged. Weighs 16 grams.
10.4 x 5.8 x 4.4 cm. An UNUSUALLY GEMMY Himalaya tourmaline on matrix, surrounded by blades of snowy white albite intergrown with pretty lavender books of lepidolite. These three minerals had the serendipity to grow together in an unusually attractive combination on a vein of feldspar, and the miner was actually able to extract it with both terminations of the tourmaline intact! The tourmaline measures 3 cm.
10.6 x 1.1 x 1.1 cm. This is a large, DOUBLY-TERMINATED gem tourmaline from the Cruzeiro. It is gemmy from top to bottom, with deep bottle-green color. The terminations are a bit rough, but are natural and undamaged. A very impressive gem crystal of 29 grams!
6.4 x 5.4 x 3.4 cm. From the notable collection of Gene Meieran, an absolutely wonderful Himalaya Mine specimen featuring a chunky tourmaline crystal jutting from the center of a euhedral quartz crystal! There is a second, smaller crystal behind the big one. The larger crystal measures 2.5 cm across the termination in the longest direction, so it is a real fatty. It is translucent, with a sort of golden color and a thin green termination. The terminations of both crystals are pristine. This is not one of those specimens where you see the tourmaline amidst a sort of hacked-out piece of quartz - this translucent quartz crystal formed sharp euhedral faces around the tourmaline, like a tree growing around a fencepost.
10.0 x 4.5 x 1.3 cm. A CLASSIC, OLD-TIME and BEAUTIFUL Santa Rosa Mine CABINET tourmaline. A gorgeous, super-gemmy, red and steeply pyramidal termination caps a large, very dark green tourmaline. The one very clean repair at the middle of the crystal is barely noticeable, on this otherwise pristine specimen. These fine, old pieces came out in the 1960s and 70s. 45 grams.
5.5 x 2.2 x 1.4 cm. A beautiful and aesthetic, multi-crystal specimen of gemmy and lustrous, green tourmaline crystals from the famous Cruzeiro Mine of Brazil. Classic, older material from the 1960s or 70s.
5.4 x 1.8 x 1.6 cm. A striking and beautiful, GEM, pencil, green tourmaline jauntily rests on a nest of smaller tourmalines on this very showy and excellent specimen from an UNCOMMON Brazilian locality - the Corrego Pomarolli Mine. Choice material.
8.1 x 4.7 x 3.6 cm. A STRIKING, LARGE, highly lustrous, raspberry-colored tourmaline with a yellowish-tan termination from Alto Ligonha, Mozambique. Alto Ligonha tourmalines are seldom on the market and this is a large, complete all-around beauty with numerous gemmy areas. Pristine, except for one clean repair laterally at the midpoint. Highly representative from this famous, but uncommon locality. 284 grams.
4.4 x 2.8 x 2.3 cm. A vibrant blue-green, 1.7 cm, indicolite tourmaline proudly rests on a matrix of bladed albite on this very aesthetic miniature from Aracuai, Brazil. The gemmy tourmaline reminds me of a lighthouse on a rocky promontory.
3.2 x 1.9 x 1.2 cm. A superb etched scepter of Tourmaline. The luster is fabulous, and the striated faces are very aesthetic. The color ranges from mint green to forest green, and the cap is extremely gemmy. A fantastic tourmaline in every respect. Ex. Charlie Key stock.
