4.4 x 1.1 x 1.1 cm. A Paprok tourmaline crystal of superb quality: gemmy from top to bottom. It features a grassy green body with a bright pink termination; the termination is like a clear glass window into the limpid interior. Weighs 10 grams.
8.1 x 1.4 x 1.1 cm. A beautiful elongated crystal of gemmy tourmaline from Paprok, doubly-terminated, with accenting matrix at the bottom. This crystal is gemmy from top to bottom. The color goes from a lighter green at the bottom, to an intense green through the center, culminating in a perfect pink termination characteristic of Paprok tourmalines. Weighs 13 grams.
3.9 x 2.1 x 1.8 cm. A fine gem tourmaline crystal from Paprok that is pretty much "classic" in form and coloration for this locality - with a bright green body and a glassy, gemmy pink tip. Also familiar is the multi-peaked termination. Complete all around, with no contacts or damage. Weighs 28 grams.
3.9 x 3.6 x 0.6 cm. A slice from a Namibian tourmaline crystal that looks like candy. The coloration is amazing: a teal-blue core, wrapped by hot pink, in turn wrapped by green. Polished on both sides. Ex. Dave Mansfield Collection (dealer Sid Pieters’ son-in-law).
5.6 x 3.4 x 3.3 cm. A big, fat pink tourmaline crystal from the Pala Chief, a locality from which it is hard to find specimens now. The one drawback to this crystal is that the termination has been (lightly) polished. The body of the crystal lights up an amazingly hot pink color under good light. It is translucent-to-transparent. This is an old-time piece. Weighs 23 grams. Ex. Bill Larson Collection.
8.2 x 6.4 x 3.8 cm. Two elegant, pastel pink crystals splay out form a cluster of pale purple lepidolite and white albite clusters. The tourmalines are 7.5 and 7.75 cm in length, and about 1.5 cm across at the terminations (the larger cluster of two tourmalines is actually 2.5 x 1.7 cm at the termination). This elegant specimen is completely viewable 360 degrees around and is totally pristine and free of repairs - remarkable for a specimen so exposed in the pocket. The colors are muted and pastel, both of the tourmaline and lepidolite.
1.7 x 0.6 x 0.5 cm. Here we have a beautiful single crystal of gemmy Rubellite Tourmaline with sharp, glassy faces and excellent cranberry color at the tip. There is a small area with a whitish zone in the crystal as well.
1.8 x 1.2 x 1.1 cm. A superb gem tourmaline crystal featuring an extraordinary range of colors, right up to the super-subtle pink at the extremity of the termination. Also has a fine teal stripe. Complete all around, no contacts. Weighs 8 grams. From Mina Poa Alt, Coronel Murta.
5.0 x 1.2 x 0.8 cm. A gorgeous gem crystal of tourmaline from the Cruzeiro Mine, balanced between a hot pink top and glassy green bottom. It is complete all around, uncontacted and undamaged, with a fine termination on top. Great luster, too. Weighs 10 grams. Ex. Steve Smale Collection.
4.8 x 2.4 x 1.8 cm. A fine gem crystal that is typical of this great tourmaline locality in many ways: from the grassy-green body and pink top, to the absolutely glassy termination you can look down into like water. Weighs 38 grams.
6.6 x 5.2 x 3.1 cm. A classic, old-time watermelon tourmaline from the historic Plumbago Mine of Newry, Maine. The glassy, gemmy, well-striated, green rind surrounds the translucent, vivid, watermelon-pink core on this historic piece. This is a large, well-terminated crystal. Probably mined prior to 1900, but no proof. 169 grams. Ex. George Elling Collection.
5.4 x 1.8 x 1.4 cm. A fine gem crystal of tourmaline from Paprok, with a layer of grassy-green sandwiched between two pink sections. This is actually a compound crystal, with the thin sidecar termination right next to the "main" crystal. The terminations are typical for Paprok: fine, transparent and glassy. The crystal is doubly-terminated (though rough on the bottom end, appearing more like a contact face with coating). Weighs 30 grams.
4.4 x 3.2 x 2.4 cm. A beautiful combination specimen from the Shigar Valley of Pakistan. A totally gem, complexly terminated, 2.5 cm, champagne-colored topaz crystal rests at the foot of a gemmy, bi-colored, green to teal-blue tourmaline "smokestack". The tourmaline has a frosted pyramidal termination. The topaz and tourmaline are pristine. Lustrous, pearlescent, bladed cleavelandite completes this combination piece.
2.3 x 2.3 x 2.1 cm. A superb, rare, combination thumbnail from Stak Nala, Pakistan. A 2.1 cm, gemmy, lustrous and striated, bi-colored, green with a teal-blue, indicolite termination tourmaline has a 1.1 cm, sharply hexagonal, gemmy and lustrous, pastel-pink apatite crystal attached to the side. Sharp albite crystals partially encircle this piece. This is definitely older material from the 1980s finds.
4.0 x 4.0 x 1.2 x 0.9 cm. An old-style crystal of tourmaline from the Cruzeiro. These bottle-green crystals are often hollow (this one is through the bottom part) with a fibrous interior. Complete all around, with perfect termination.
