A very rich specimen with tourmaline crystals to 7 cm embedded in lepidolite matrix. The tourmalines are forest green in color and they have an odd, silky lustre to them that is hard to capture. There are some smaller broken crystals, but the 2 major ones are pristine and terminated. 14 x 10.1 x 6.3
6.6 x 3.9 x 4.4 cm. An unusual cluster featuring a very translucent tourmaline poking out of a mass of tourmaline and lepidolite. Also rising up in tandem is a lepidolite crystal (a real crystal, not just massive material). The mass of tourmaline, and the tourmaline attached to the lepidolite, is damaged but colorful. The main, centerpiece tourmaline is pristine, stands 2 cm tall and has a very intense blue cap.
7.9 x 5.6 x 4.1 cm. This specimen is a solid mass of gemmy green tourmaline, with a 5-cm-long central crystal, all draped in sparkling lepidolite. Luckily, instead of coating the entire piece, the lepidolite has provided just the right contrast to make this a pretty piece. The lepidolite are sort of beige in color, quite different from the new material on other pieces here, but classic for this particular mine. The main crystal is pristine and complete (though the secondary crystal at its base is not).
5.4 x 3.6 x 2.8 cm. From this recent find of really unusual, translucent lepidolites comes a fine miniature with the tourmaline bisecting a cluster of those neat lepidolites. The 3.5-cm-tall tourmaline stands in the middle of the joined lepidolite group. It is draped by a later generation of sparkling lepidolite crystals of smaller size. An unusual combination piece.
4.7 x 3.1 x 1.6 cm. An unusual combination piece where the lepidolite is more than just accent, because the balance of crystal to crystal is so even. The tourmaline is very gemmy and lustrous; and the lepidolite is equally lustrous, slightly translucent, and sparkling.
4.1 x 2.1 x 1.7 cm. This is a pastel green tourmaline almost completely replaced (pseudomorphed) by brilliantly sparkling, lavender-colored, translucent lepidolite. Complete all around but for a shallow bit of damage to the back of the tourmaline termination. As the tourmaline dissolved away in pocket, the lepidolite crystals grew into the vacant space, preserving the overall form and symmetry. Usually, this replacement (seen most often from old Pederneira mine workings) results in ugly lepidolite with no lustre, and more faithful symmetry of the tourmaline. This way of doing it creates a much more attractive result of a pseudomorph caught in action.
22.3 x 18.5 x 11.0 cm. This plate is draped by thick, brilliant yellow lepidolite clusters. The lepidolite is wonderful for this find and the plate is a huge example. As a bonus, on the bottom side, you have a rare mineral species first described from this locality. Guimaraesite is a newly (2006) described complex calcium/zinc/magnesium/iron beryllium phosphate, which comes from an unnamed pegmatite working in this valley. Guimaraesite in sub-mm spherical crystal clusters abounds on this specimen. The whole piece weighs 7.5 pounds. This is pristine and even complete around the 3-dimensional edges, overhanging a bit of quartz matrix embedded underneath. Most of the larger clusters are translucent, and richly yellow.
Recently, some very attractive 3 – 4 cm “balls” of lepidolite with the general appearance of the lepidolite on this specimen have come from Brazil. But this is the first I have EVER seen on matrix – and a fine matrix of snowy Albite blades, at that! The lepidolites, with a pleasing lavender color, are isolated on the matrix, and have a brilliant luster across their curved surfaces. Lepidolite is typically an “accent” mineral, but here is a rare specimen where it is really the star! I know its not the most glamorous species, but to me that makes such a piece all the more desirable. 8.5 x 5.5 x 5 cm
6.1 x 4.6 x 3.0 cm. A crystal that resembles pale blue glass with its incredibly gem/gemmy interior and lustrous, sharp, bright faces. The piece has beautiful form with an elegant amount of pale tan Lepidolite at the base. The display side of the piece is incredibly sharp and smooth, while the reverse side has graceful hydrothermal etching. The Xanda mine is one of the most prolific localities for blue Topaz in the world, and has produced some of the most impressive and memorable specimens with that distinctive preferential etching and larger sized crystals. Ex. Richard Kosnar Collection.
A dramatic, beautiful, unusual and pristine specimen of purple lepidolite and pearly-white cleavelandite attached to the termination of a gemmy green at the base and grading into very dark green tourmaline at the termination from the famous Golconda Mine of Brazil. 8.3 x 4.5 x 2.6 cm
5.8 x 5.5 x 4.5 cm. Beautiful, gemmy and lustrous, watermelon tourmalines are attached to both sides of the very showy matrix of pearlescent, blades cleavelandite richly accented with lustrous, purple lepidolite. The large tourmaline is 4.5 cm. It has superb and classic Pederneira tourmaline color characteristics, with very bright colors. The striking, central core of vivid, raspberry-red has a thin, outer sheath of green. The lustrous cap is a spectacular, gemmy, teal-blue. The horizontal tourmaline penetrating the large tourmaline is fascinating. This is a very beautiful, very aesthetic matrix tourmaline specimen.
6.7 x 3.6 x 1.6 cm. An aesthetic and striking polychrome tourmaline crystal cluster from recent finds at the Pederneira Mine of Brazil. This stunning piece looks like a stylized "7". The gemmy and lustrous crystals are mostly green, but the "arm" crystal has a gorgeous, teal-blue, indicolite zone. Both crystals have a core of light cranberry-red. The tourmalines are beautifully complimented by a sprinkling of gemmy, pink lepidolite crystals. The distinctive, spiky termination is comprised of many, parallel-growth crystals. This complete-all-around super piece is nearly pristine.
4.9 x 4.5 x 3.5 cm. Gemmy, barrel-shaped, lavender lepidolite crystals to 1.3 cm are aesthetically set on a sharp, euhedral microcline crystal from the Himalaya Mine. The microcline crystal has a distinct, 4-sided, pyramidal shape and is nicely accented by a bit of bladed cleavelandite.
A simply gorgeous, aesthetic, gemmy, lustrous indicolite tourmaline with smaller protruding tourmalines, purple lepidolite crystals and a lustrous, white blade of cleavelandite. The darker pinacoid termination has low lustre. The one barely noticeable termination edge ding has no effect on this beautiful specimen, which hails from an unidentified Minas Gerais, Brazil locality (though I suspect it is Golconda Mine or area) 4.1 x 3.1 x 1.8 cm
Gorgeous, transparent to translucent, gemmy, lustrous and striated bi-colored tourmaline crystals from Pech, Afghanistan. Lepidolite crystals are attached to the sides of the pristine and beautiful watermelon grading to pastel-green tourmaline crystals. A superb and aesthetic specimen that is among the most glassy of tourmalines you will ever see, in terms of surface lustre! 5.5 x 1.6 x 1.4 cm
