9.9 x 8.2 x 6.4 cm. A fine and unusual specimen from the Richard Hauck Collection and Minas Gerais, Brazil. The water-clear quartz crystals are heavily invested with schorl needles. None of the multitude of schorl crystals protrude out of the quartz crystals. I like the jackstraw pattern of quartz crystals and how the pearlescent cleavelandite compliments and accents the dark, included quartz crystals. The two, tiny, schorl-included quartz crystals on the cleavelandite are a very nice accent. The large quartz crystal is 9.5 cm and is doubly terminated. The lower, large quartz crystal is also doubly terminated and is 9.0 cm long.
10.0 x 1.8 x 1.6 cm. A really interesting, curved, cabinet schorl crystal from recent finds in the Shigar Valley of Pakistan. Tectonic forces during crystal growth caused this large, parallel-growth schorl to bend. The crystal is highly lustrous and striated and has multiple, matte, pinacoidal terminations.
3.8 x 2.8 x 2.4 cm. A lustrous, striated, jet-black schorl crystal with a sharp, pyramidal termination from the well-known, but less common locality of Alto Ligonha, Mozambique. Highly representative of the species and locale. Ex. George Elling Collection.
5.5 x 5 x 3.8 cm. A cluster of seven lustrous and beautifully-striated Schorl crystals. Each has the trigonal termination classic for Erongo. The larger of 2 major crystals is 5 cm in length, and the occasional etching on the crystals adds interest and contrast. Ex. Charlie Key Collection.
12.7 x 2.5 x 2.1 cm.
A fine, exceptionally large Schorl crystal with classic superb striated faces. The trigonal termination is well-formed, and slightly etched. Ex. Charlie Key Collection.
17.8 x 2.6 x 5.4 cm. This tourmaline surprised me. I expected it to be broken on both ends when I first saw the photo in a collection a few months ago, but it is actually doubly-terminated: a floater, complete all around. The top termination is a sharp, flat, lustrous termination as you would expect. The bottom termination is a strange nest of elongated, acicular tourmaline growing from the main body of the crystal and yet still joining to culminate in a termination. The twisting and bending of the crystal is the most severe that I have seen in a tourmaline specimen I can recall, and indicates tectonic forces and movement of the crystal within the pocket as it was forming. Normally, such dramatic bending would be accompanied by dramatic cracking and breaking. However, this thing is miraculously intact, with no repairs. It somehow survived the constant breaking and re-healing process that formed the curvature you see. Ex. Saller collection of Germany.
8.4 x 5.0 x 2.0 cm. This is a rare, fine goshenite from the Erongo Mountains in Namibia. These have smooth, glassy faces with crackly interiors, and not a bit of blue color to be seen; they are true goshenites (a lot rarer than aquamarines). The biggest crystal here is 2.2 cm long. This is an excellent and very rich plate, nicely accented with lustrous, black schorl crystal clusters.
4.9 x 2.6 x 2.3 cm. A strane, unusual, but very fine Erongo aquamarine crystal. This sharp, very glassy, hexagonal crystal is a pastel-blue, almost a goshenite beryl, on the outside, but the core of the crystal is a very intense blue. The pristine crystal is complete-all-around. The sidecar aquamarines and the tiny schorls embedded in the termination are nice accents. Ex. Charlie Key dealer stock.
A pristine, superb and lustrous attached floater pair of schorl crystals from the Erongo Mountains of Namibia. Display possibilities are endless. 3.6 x 2.2 x 2.0 cm
15.4 x 6.9 x 6.7 cm. An outstanding cluster of four equant, highly lustrous Schorl crystals on Smoky Quartz matrix. The largest of the Schorls is about 4 cm across, and each has superb luster. The four crystals grew in a flower-like cluster on the matrix, sitting perfectly on the Smoky Quartzes. Ex. Charlie Key stock.
5.5 x 2.1 x 1.6 cm. A striking doubly-terminated and gemmy 5.5 cm Aquamarine, with a nicely-terminated intergrown Schorl and attached Orthoclase. The luster is excellent, and the gemmy terminations are absolutely mirror-like. Ex. Charlie Key stock.
7.5 x 6.6 x 5.5 cm. An amazing combination piece of well-defined books of Mica that form dense radial aggregates around a large, highly lustrous Schorl crystal. The largest Mica cluster is almost 7 cm across, but there is an equally aesthetic 3 cm ball of Mica near the end of the 3.5 cm Schorl. Ex. Charlie Key stock.
3.3 x 2.5 x 2 cm. A superb Erongo Aquamarine/Orthoclase so reminiscent of the great piece on the cover of the May/June 2007 Rocks & Minerals that I would bet it was from the same pocket (...and they both were from the same collection as that piece came from me as well). The gemmy, doubly-terminated Aquamarine is 2.6 cm long, and rests perfectly on a cluster of sharpy euhedral Orthoclase crystals. Ex. Charlie Key stock.
8 x 2.8 x 2.4 cm. An elegant and lustrous 8 cm Schorl crystal. The finest features are the crystalline fans that splay outward, adding a level of drama and beauty not often found with a Schorl. The white coating, hyalite opal, adds a beautiful contrast and flair to the sides, back, and termination. Ex. Charlie Key stock.
6.6 x 5.6 x 4.6 cm. An unusual and quite attractive Fluorite & Schorl specimen from the Erongo Mountains in Namibia. The gemmy Fluorites, the largest of which is 2.4 cm, are highlighted by preferential deep purple coloration on all the smaller modified faces. Note the outlying and most isolated crystals at one end are spinel twinned. The effect is quite dramatic, both for zoning and creating an overall deep purple cast. Schorl crystals up to several centimeters grow both through and alongside the Fluorites. Ex. Charlie Key stock.
