4.8 x 4.5 x 2.7 cm. A green tourmaline of classic style for this mine, from which a large production came out about 5 years ago and recently, not much at all. The crystal is embedded in a mass of crystallized lepidolite. Moreover, it seems to be altering to lepidolite.
7.4 x 2.6 x 2.3 cm. A highly unusual crystal for this mine, in its habit, this is a beautiful, unrepaired Pederneira tourmaline. It looks more like material from Sao Jose da Safira or old Golconda in style, and yet the color zoning and pattern is totally Pederneira. As well, it was collected recently there. The colors are intense when backlit. The complex termination, again, is unusual for the mine but not unattractive. Weighs 69 grams.
15.9 x 7.0 x 4.6 cm. A 3.2-cm-long indicolite blue tourmaline is perched atop an elongated, sharply terminated quartz point. The tourmaline is terminated atop, though broken off on its bottom end. Sparkling purple lepidolite decorates the lower half the of the quartz (which is nearly a floater). Weighs 456 grams.
4.7 x 1.8 x 1.4 cm. An unusual, castle-like growth of intermixed rubellite tourmaline and quartz, grown into each other. This is a Jonas Mine tourmaline from the classic 1978 find here, with the right color if not gemminess to it. It is not a typical Jonas at all. The top is terminated, etched into an elongated termination.
3.6 x 1.3 x 1.3 cm. A beautiful, very sharply color-zoned single crystal from recent reworking at the classic old Golconda Mine. It is a very lustrous, gemmy crystal with unusual color patterns not seen from other Brazilian localities. It is nearly pristine. Weighs about 12 grams.
8.4 x 2.3 x 2.0 cm. This elegant crystal splays outward from its base, widening from 2 cm to 2.5 cm by the time it crests at its widest point just under the termination. The crystal is complete-all-around, 360-degrees. It has extremely high lustre and the most intense green color this locality produces, before a transitional clear zone under the termination. The termination is complete-all-around, and its apex is so intensely maroon in color, it is almost purple in person (the camera cannot capture the lustre and the color precisely). From mining in 2008. Weighs 59 grams.
3.2 x 1.6 x 1.4 cm. A beautiful, gemmy and lustrous, polychrome tourmaline from the Himalaya Mine. The classic, well-striated crystal has the pleasing, vivid, "Himalaya pink" body. The base is hues of green and the lustrous, modified, pinacoidal termination is light gray. This fine older piece probably dates to the 1960s or 1970s. Complete-all-around and nearly pristine. Ex. Robert Whitmore Collection #24. Weighs 13 grams.
8.1 x 4.8 x 2.3 cm. The striated prism faces and pyramidal terminations on this very fine doubly terminated, floater tourmaline (variety verdelite) are highly lustrous and translucent. This striking older Brazilian crystal, probably from the 1960s or 1970s is complete-all-around and pristine. The back almost looks as good as the front. The basal termination was broken, healed and overgrown with matte-green tourmaline. Verdelite is a green variety of tourmaline. This specimen formerly belonged to the well-known Spanish collector Albert Botella Ripoll, part of whose collection was acquired by the Houston Museum in 1996. Weighs 99 grams.
4.1 x 1.3 x 1.1 cm. An incredible, totally gem, cranberry-red tourmaline crystal. The color is outstanding and reminds me of fine Jonas or Cruzeiro Mine material. This is older, very high quality and very uncommon, for the color crystal is from the Himalaya Mine . Ex. Robert Whitmore Collection. Complete-all-around and pristine. Weighs 62.2 carats or over 12 grams.
6.2 x 2.2 x 2.1 cm. A strangely, heavily etched, broken and healed, polychrome tourmaline from recent finds at the Pederneira Mine. The two broken and healed breaks are obvious in the sides of the gemmy and lustrous, green to blue-green to teal-blue crystal. The lower break has caused the crystal to bend. Three-fourths of the interior of the crystal has been etched away, as has a striking, significant portion of the side. The highly lustrous termination is scalloped. An interesting and most unusual tourmaline from the Pederneira.
5.1 x 2.2 x 1.8 cm. This specimen bright green color at the bottom, and a glassy, bright lavender (rare), pure gem, complex termination with flashing faces. No contacts or damage. Weighs 39 grams. This is a superb crystal, from a small find made 1 year ago.
6.0 x 5.8 x 3.6 cm. A striking, old-time tourmaline from the Santa Rosa Mine of Brazil. The highly lustrous, translucent, rich green, parallel-growth tourmaline crystals have an incredible number of turreted, castle-like terminations on both sides. Material of this quality probably dates to the 1960s or 1970s. Ex. Daniel Trinchillo Sr. Collection.
4.5 x 1.0 x 0.9 cm. A beautiful, gemmy and lustrous, highly desirable, "red-tip" tourmaline from the Cruzeiro Mine. The gemmy, cranberry-red, pinacoidal termination dramatically turns downward to a starkly contrasting, very gemmy, steel blue-gray. This specimen is complete-all-around and pristine. This is classic, old, 1960s-1970s material from this renowned locale. Ex. Steve Smale Collection. Weighs 8 grams.
3.8 x 3.7 x 2.8 cm. An interesting and older combination specimen from the Himalaya Mine and the Robert Whitmore Collection. A gemmy and lustrous, well-striated, multi-hued green tourmaline crystal is very aesthetically accompanied by an angled, doubly terminated quartz crystal and a lavender lepidolite book. The tourmaline is doubly terminated. This classic Himalaya piece dates to the 1950 or 1960s.
4.1 x 1.7 x 1.6 cm. A superb and rare vivid pink tourmaline from the early 1960s find at the Golconda pegmatite. The gemmy and lustrous crystal is complete-all-around and is pristine. It features textbook hexagonal crystal form. The termination area is particularly gemmy and the pinacoidal termination itself is lustrous and lightly etched/frosted. The internal crazing adds character to the crystal. Weighs 25 grams. Ex. Robert Whitmore Collection #8.
