4.4 x 2.6x 2.5 cm. A classic and unusual, Himalaya "pink" tourmaline. This gemmy and lustrous, well-striated crystal has gemmy, lavender lepidolite crystals embedded on all three sides. Both terminations were broken by pocket forces, but have re-healed, making this a doubly terminated crystal. One termination re-grew a different color of pink and has cleavelandite blades, lepidolite and cookeite crystals embedded in it. The other termination has a very slight re-growth. Older material from the 1960s to early 1980s. Ex. Robert Whitmore Collection #47. Weighs 45 grams.
13.0 x 5.6 x 5.4 cm. This impressive specimen features a sharp, doubly-terminated gem crystal from the so-called “Rocket Pocket", 10.8 x 1.4 x 1.2 cm in size, perched delicately on the side of a knoll of crystallized cleavelandite with sparkling purple lepidolite in the interstices. Collected around 2002, this was considered at the time, in the context of having most of the pocket contents laid out on a few giant tables to be sorted, to be one of the best of this style in its size range. It was kept back by one of the partners in the Pederneira Mining venture, and then sold to collector Irv Brown. He selected it because it has very unique aesthetics and, unlike most of these larger crystals which have 2-4 repairs, it has only one very clean, lock-fit repair to the tourmaline crystal. I obtained it in exchange from him in about 2006. The Pederneira is shut down for the moment, and in any case the pegmatite which hosted this particular pocket is completely gone and stripped of crystals at this point. I admire the contrast between the large crystal with pyramidal termination and the two smaller crystals flanking it, each with a flat-topped termination. The balance of the piece, the accents by the sidecar crystals, the combination of terminations, all make for a superb specimen in its size class.
A gemmy, lustrous and pristine deep-pink tourmaline crystal from the famous Himalaya Mine. There is a thin band of green tourmaline just below the termination, which adds to the attractiveness of this specimen. This piece is partially etched and has three purple lepidolite crystal clusters aesthetically attached to the sides. The backlit photo highlights the variations of pink and the thin green band in the crystal. 5.5 x 2.9 x 2.8 cm
20.7 x 17.1 x 7.6 cm. This is one of the two largest plates we have found that is uniformly of the top quality for the find, with large radiating aggregates to 1 inch of the best color and lustre; and with a good edge horizon, minimal damage (only a few trivial edge bits), and good overall display aesthetics.
17.8 x 9.0 x 5.0 cm. The only specimen I have seen like this, in such quality. This piece has a 9 cm doubly-terminated quartz atop a larger, extended quartz shard; and the whole quartz shard is included here and there by beautiful lepidolite, giving a golden "glow" when backlit o the whole specimen.
Pretty lavender lepidolite, with an almost metallic sheen, formed in a myriad of shell-like layers into what is known as "ball" lepidolite. Unusual! 3.6 x 3.1 x 2.2 cm
7.3 x 5.3 x 4.9 cm. This is a massive 295-gram rubellite crystal from a lesser-known mining district by today's production. It has a most unusual magenta color in person, with a touch of blue or purple you do not normally see in rubellite from Brazil. The piece has a beautiful display face on the front, and you can see the diagonal lepidolite blades attached on back, arching over from behind, at this angle. The termination is most unusual, basically a 1mm black, matte cap atop an otherwise normal core.
10.5 x 9.1 x 5.9 cm. This specimen is a beautiful arrangement of truly gem-blue indicolite tourmaline nestled in a glistening matrix of purple, sparkling lepidolite. The Pederneira, in its recent heyday of the early 2000's , briefly gave the market a flood of good tourmaline matrix specimens (most repaired, but acceptable in context). Even with the quantity produced, each pocket was different and when you really get down to thinking about it, few of the finds were of blue tourmaline - and fewer yet on matrix. Matrix indicolites are in fact quite rare from any locale. This piece features 3 major and several minor crystals. The large central crystal is 8.6 x 1.3 x 1.3 cm, with a clean repair at midpoint. It is perfectly terminated and very gemmy and transparent. It has a totally freestanding termination. The forward-facing crystal, to its right, is 3 x 1.5 cm 1.2 cm and is doubly-terminated (the front termination is oddly rippled, but in an interesting manner; the back termination is matte and dull). The slender, totally gemmy crystal pointing to the left is actually 6 cm long, thought most of that length is hidden on the backside of the specimen and not visible from the front.
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.
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.
Just a really nice reference specimen of classic ol' purply lepidolite! 5 x 4 x 3.5 cm
"Just a lepidolite", i know, but what a crystal! unusually 3-D! 2.6 x 1.6 x 1.6 cm
Neat inclusion! 3.25 x 2.2 x 2 cm
A very attractive matrix Pederneira specimen, with a classic 5-cm multicolored tourmaline jutting out from behind a gemmy, doubly-terminated quartz crystal. It can be displayed either horizontally or with the crystal vertical (not shown but you get the idea) . Other quartz crystals and platy albites decorate the lepidolite matrix. There is one clean repair on the tourmaline behind the quartz, where it cannot be seen anyhow; but of course, nearly ALL Pederneira pieces have at least one repair – most, more than that – so it is not considered a detraction. 6.6 x 5.8 x 4.2 cm
10.8 x 4.2 x 3.4 cm. This is a really fine, large crystal of classic Himalaya Mine rubellite, showing a lustrous basal termination at one end (top here) and a multiterminated prismatic tip at the other (shown down here as he mounted it). It has one clean repair, well done, at the join where the albite is. It is otherwise complete-all-around. This is a significant piece for the size and overall quality from a mine that really was, in its day, the single most important longterm-production tourmaline mine in the County. The location is now closed. Ex. Chuck Houser Collection.
