8.2 x 7.4 x 4.4 cm. A large and magnificent tourmaline specimen on matrix from Paprok. This big, fat juicy crystal, with multiple hues of intense green, measures 3.75 cm long-ways across the termination (and is 5.75 cm tall), and it is attached to a stark white euhedral crystal of albite that shoots off the backside and upwards, providing contrast to the green termination. The tourmaline has a perfect, glassy, flat termination on top.
2.2 x 1.7 x 1.6 cm. Teal-blue and purple are RARE colors for tourmalines from the Stewart Mine of California. This gemmy and lustrous crystal has an opaque base grading upward to teal-blue, then a narrow green band, followed by teal-blue and topped with a purple cap.
7.1 x 6.6 x 5.1 cm. A gemmy and lustrous, pristine, 4.0 cm, teal-blue, indicolite tourmaline nestled between three, very glassy, colorless quartz crystals from Pech, Afghanistan.
2.1 x 1.0 x 0.7 cm (largest). A set of 11 gemmy and lustrous, rose-red and light green tourmaline crystals from a new find at Aracuai, Brazil. 25 grams total weight.
5.9 x 1.5 x 1.2 cm. A striking, gemmy and lustrous polychrome tourmaline from Paprok, Afghanistan. Ex Steve Smale Collection. The vibrant pink body is beautifully highlighted by the green zone within the water-clear area, just below the termination. The termination has an unusual, almost bronze-like color to it. The partial collar of cleavelandite at the base is a nice accent. 12 grams.
5.4 x 3.7 x 2.9 cm. A gemmy and lustrous, polychrome tourmaline aesthetically wrapped in two generations of lustrous lepidolite blades, purple and tan, from an uncommon Minas Gerais pegmatite, the Arqueana Mine, Governador Valadares. The beautiful green body has a teal-blue indicolite zone below the lusrous, frosted termination. Ex. Marty Lewadny Collection. 63 grams.
4.8 x 2.2 x 2.0 cm. A fine, gemmy, multiply-terminated crystal of tourmaline from Paprok. It has a wonderful peridot color at the termination, with a grassier green color beneath this, and pink at the base. The terminations on top have an unusual silky luster to them. The crystal is complete all around. Weighs 30 grams.
4.7 x 1.2 x 1.2 cm. A super-gemmy crystal of tourmaline from Paprok, weighing 11 grams. It has a fine termination, and is complete all around, with good luster.
8.3 x 0.8 x 0.7 cm. With a pretty multiple termination on one end, a long, slender tourmaline crystal from Brazil. The bottom is dark green, grading to a lighter bottle-green around the middle, and pretty pink at the termination. Weighs 10 grams.
3.8 x 0.9 x 0.9 cm. A gem tourmaline crystal from the Cruzeiro, with a glassy green center and perfect pink termination. The crystal has an outer rind wrapped around an inner core, from two generations of growth. Weighs 6 grams.
5.6 x 0.6 x 0.6 cm, 4.4 x 0.7 x 0.4 cm. Two gem tourmalines from the Pederneira Mine - both pure gem material, and both with beautiful multiple terminations on top. They are complete, uncontacted and undamaged.
3.2 x 0.8 x 0.6 cm. The Baixao Mine is not as well-known as other gem tourmaline mines in Minas Gerais, but it produced some extremely fine crystals, with superb clarity, such as this light grass-green gem. It has super luster and a perfect termination, as well.
3.5 x .8 x .8 cm. A gemmy, light pink to clear Nepalese Tourmaline with excellent luster. This 5 g crystal is very aesthetic with the overall gemminess accented nicely by the pink and clear zones. Ex. Charlie Key.
5 x 3.5 x 1.7 cm. A fine, gemmy Indicolite from the famous Otjua Mine in Erongo. This gorgeous crystal has superb luster, good habit and termination, and is 59 g of blue gem crystal. Ex. Charlie Key.
7.3 x 4.3 x 3.2 cm. A rare matrix specimen of tourmaline from the Jonas Mine, from the world-famous pocket of 1978 that is still the most important and famous single tourmaline strike in all of history. Featuring an approximately 2-inch crystal, doubly terminated and frozen in enclosing crystallized lepidolite, this is a classic representation of the find. Ex. Sorbonne and Eric Asselborn Collections.
