6.0 x 1.3 x 1.0 cm. A classy and beautiful, bi-colored tourmaline from recent Pederneira Mine finds. The beautiful, gemmy and lustrous, teal-blue body is capped by a glassy, yellow-green, pyramidal termination. The little purple lepidolite rosette is a nice accent. Complete-all-around and essentially pristine. An excellent bi-colored, indicolite tourmaline from the world famous locale.
3.4 x 1.4 x 1.0 cm. A beautiful, old-time tourmaline from the Cruzeiro Mine and the Steve Smale Collection. This gemmy, lustrous, well-striated crystal has intense cranberry-red color. The amazing color saturation is uniform. The lower part of the crystal is very gemmy. This is more intense cranberry-red than the famous Jonas tourmalines. The termination is a very interesting, modified pinacoid. Tourmalines of this rare and very desirable color came out in the 1960s and 1970s, with none since. Complete-all-around and pristine. Weighs 9 grams.
3.2 x 1.8 x 1.7 cm. A rich, bi-colored tourmaline from the Himalaya Mine. Most of the gemmy, lustrous, well-striated, beauty is a pleasing mint-green. The lustrous, modified, pinacoidal termination is black and the crystal base is opaque, dark green. Very nearly pristine. Solid green, older tourmalines, such as this, with the dark caps were relatively uncommon. Weighs 18 grams. Ex. Robert Whitmore Collection # 30 (definitely an older piece).
5.7 x 3.8 x 2.2 cm. A gorgeous, vivid "bubblegum-pink" tourmaline from recent finds at Paprok, Afghanistan. This gemmy and lustrous crystal is beautifully striated and the termination area is particularly gemmy. The frontal view is pristine. This striking crystal has excellent color and lustre. Weighs 47 grams.
5.5 x 2.6 x 1.6 cm. A striking, highly unusual, polychrome tourmaline from the Pederniera Mine. The front of this very fine, glassy and lustrous piece is a classic, Pederneira polychrome tourmaline. The well-striated body is a pleasing sea-foam-green, grading up to a beautiful, gemmy, teal-blue at the termination. The glassy termination, itself, is purple. The back of the piece is the surprise. Nearly all of the tourmaline has been etched away, leaving a curved hollow. Only the termination area is left and is partially etched. Needles of tourmaline are seen hanging down. Fascinating material from this famous locale.
3.8 x 1.8 x 1.4 cm. A really interesting polychrome tourmaline from recent finds at the Pederneira Mine. The crystals are very glassy, lustrous and well-striated. The crystal bodies look sea-green, but are actually teal-blue, just like the gemmy areas below the terminations. Pocket fluids nearly etched out the interiors of these crystals, up to the gemmy, teal-blue zones. The highly lustrous terminations are either very dark purple or black. Complete-all-around and nearly pristine. These are often called "retrograde" tourmalines. Striking and unusual material.
4.7 x 0.5 x 0.4 cm. A very pretty and highly unusual bi-colored tourmaline from the Himalaya Mine and the Robert Whitmore Collection. Most of this pencil tourmaline is the classic, gorgeous, gemmy and lustrous, "Himalaya pink". A very distinct compositional change occurred at the base, as the crystal is colorless and translucent. Strange, but interesting. Old material from the 1960s or 1970s, or earlier, as the piece has a Whitmore number of 22. Weighs 3 grams.
6.6 x 2.0 x 1.9 cm. This mine has produced some of the most famous Tourmaline specimens in the world. This crystal is a very attractive specimen featuring four distinct color zones. The uncommon pyramidal termination on this crystal has a pale peachy color which grades into a nearly colorless (very pale green) zone that leads into a golden-green hue, ending with a vibrant pink color through the base of the crystal. The entire crystal (including the termination) has an excellent luster, and the overall quality of the piece is very good with wonderful gemminess, bright colors, and only a few slight "rubs" on the sides of the prism. Ex. Brian Kosnar Collection.
5.4 x 1.3 x 1.1 cm. A very showy, bi-colored tourmaline from recent Pederneira Mine finds (fall 2009). This complete-all-around, doubly terminated, gemmy and lustrous beauty is zoned green and teal-blue. The highly lustrous, upper termination is black and the basal termination, with a matte finish, was broken by pocket forces, but healed. The two, protruding, tourmaline "fins" and the clearly visible slight bending at each end are super accents. Very nearly pristine. A classic and beautiful Pederneira tourmaline. Weighs 18 grams.
5.3 x 1.4 x 0.8 cm. A strikingly layered, gemmy and lustrous, gorgeous, grass-green tourmaline from the Pederneira Mine. This crystal has a very steep, strange, vertically etched, very dark olive-green to black, pyramidal termination. A classic, pristine, well-striated, gemmy, bi-colored tourmaline from this world-famous locale.
9.5 x 8.0 x 7.5 cm. A striking, most unusual combination specimen from the pegmatites of Konar Province, Afghanistan. A very sharp, gemmy, glassy, 5.5 cm wide, vivid pink morganite crystal has an unusual base/core of pretty blue aquarmarine. Surrounding this morganite/aquamarine crystal is a cluster of purple indicolite crystals, glassy, colorless spodumene prisms to 5.1 cm, smoky quartz crystals and cleavelandite blades; all on a matrix of massive albite. The termination of the morganite is pristine. The morganite is excellent quality and the morganite/aquamarine crystal itself, is actually very rare. A dramatic and rare combination specimen from this noted locale.
3.4 x 2.2 x 2.0 cm. A very rare and old combination specimen from the pegmatites at Hebron, Maine. Lustrous, brown eosphorite blades to 6 mm richly cover one vuggy side of the matrix. Another side hosts a flattened, lustrous, teal-blue indicolite tourmaline. According to MINDAT, childrenite is a discredited species from Hebron, so these must be eosphorite crystals. Comes with an expertly handwritten, faded label from an older collection. The collection this came out of was a museum stash dating to prior to World War I. Classic, very rarely available combination material from this historic locale.
3.9 x 2.3 x 2.2 cm. A classic, bi-colored, "Himalaya pink" tourmaline from the Himalaya Mine. The body of this gemmy and lustrous, well-striated crystal is the gorgeous pink, for which the locale is renowned. The base is a light olive-green and there is an interesting gem nodule there. Highly representative older material. Weighs 37 grams.
5.2 x 2.6 x 1.7 cm. A fine cluster of doubly-terminated indicolite tourmalines with a bed of lavender lepidolite crystals from recent finds at the Pederneira Mine. The gemmy and lustrous, well-striated crystals have beautiful teal-blue bodies and the pyramidal termination is light olive-green. The two adjacent crystals have broken terminations. The basal termination is broken, healed and is overgrown with some lepidolites. The gemminess, color and specimen form make this a highly representative and excellent example of the species and noted locale. Weighs 18 grams.
3.9 x 2.2.8 x 1.7 cm. A fine, complete-all-around, "mushroom" tourmaline crystal cluster from Burma, with the characteristic "cap", in this case a gemmy pink color and typical purple core. Tapered clusters, such as this, are not that common from Mogok. Little new material is coming from Burma, as a result of the trade embargo.
