11 x 9 x 6 cm. The green Erongo Fluorites have become famous in their own right, but to find them in such superb combination with the rare and desirable clear Goshenite Beryls, as well as Smoky Quartz, is a thing to behold. Both the Fluorites and Beryls range up to 2 cm, and the Smoky about 3 cm. The luster on the fluorites is silky and very good, as is the gemminess and zoned coloration. The Beryls have superb luster. Overall, this is an incredible combination piece - one of the best I have seen from this region. Ex. Charlie Key stock.
2.4 x 1.9 x 1.1 cm. A beautiful perfectly gemmy Aqua with an incredible medium blue color and superb luster. One termination is perfect. Combine this with the lustrous well-formed euhedral Schorls attached to the crystal, and you have an incredible and aesthetic specimen. Ex. Charlie Key stock.
6.2 x 5.7 x 4.2 cm. A fabulous large single crystal of Schorl that shows the unusual trigonal termination often associated with Erongo. The luster is superb, and the complex stepped growth of the faces gives this an aesthetic not often seen. For a black mineral, it is so reflective and bright that the pic does not do this beauty justice. An amazing Schorl. Ex. Charlie Key stock.
6 x 4.7 x 4.2 cm. A beautiful and highly lustrous Schorl on Smoky Quartz. The faces and edges are very sharp, and the luster is out of this world. Although there is varying amounts of contacting on each termination, this Schorl is actually doubly-terminated. There are even some fluorescent minerals attached. A beauty in its own right. Ex. Charlie Key stock.
8.5 x 7.7 x 5.7 cm. A gorgeous 4.8 cm Aqua on a matrix of Smoky Quartz and Schorl. The Aqua has superb luster and a fantastic .6 cm gemmy termination. Much better in person, this very much reminds me of the Aqua on the cover of the MR "Erongo" special issue. Ex. Charlie Key stock.
4.2 x 3.9 x 2.1 cm. Incredibly sharp and lustrous crystals of schorl, intergrown with contrasting feldspar that sets them off nicely.
12.9 x 9.8 x 5.1 cm. A cluster of elongated, fibrous-looking crystals of schorl tourmaline. A few of the terminations are intact. One of the crystals broke in the pocket and then healed naturally, so that it has an interesting bend in it now!
3.3 x 0.7 x 0.6 cm (largest). An excellent 4-piece set of OLD-TIME, highly lustrous schorl crystals from the famous Rollstone Hill Quarry at Fitchburg, Massachusetts. Three of the four crystals appear to be terminated. The quarry closed in the 1940s. Ex. George Elling Collection.
4.1 x 3.3 x 2.8 cm. A striking specimen of this now familiar combo from the Erongo Mountains. The schorls are highly lustrous and sharp, with a truncated form. The aquas are GEMMY and DOUBLY-TERMINATED (this is in fact a floater specimen).
4.2 x 3.8 x 3.3 cm. A CLASSIC, DESIRABLE and SHOWY California specimen from the famous Little Three Mine. I cannot begin to say how rare unetched crystals in this size range are, especially when emplaced on nice white matrix. This has a 2.0 cm, pristine, gemmy and lustrous, deep orange spessartine garnet is aesthetically perched atop etched albite. A lustrous and striated schorl is encircled at the base by the albite. The schorl has a broken, but healed termination (typical for the locality where the pegmatite is severely fractured and stressed). These are very rare, mostly found in the 1960s and 1970s. This is a competition level miniature, as well as being a classic US mineral from this famous (and for all intents defunct) mine.
11.4 x 10.2 x 5.9 cm. Yes, it is "just" black tourmaline (schorl), but you can see what a dramatic and large crystal specimen this is. There are a dozen crystals here, beautifully lustrous, and the piece was extracted with most of the terminations complete - in fact, ALL of them at the center of the specimen save one contacted termination. Upon close inspection, it appears likely that even the terminations at the periphery and the contacted one in the center healed naturally in the pocket. The crystals measure up to 5 cm. What makes them really pretty is the contrast with the stark white matrix.
13.1 x 3.9 x 2.9 cm. A quartz crystal densely included with a variety of Riverside County minerals - montmorillonite (clay), the whitish stuff, along with cookeite -- and, a cluster of schorl tourmaline crystals, including one long one that extends most of the way up the side of the quartz crystal. There are little needle-like crystals of schorl shooting through the center of the quartz as well.
5.4 x 4.2 x 4.2 cm. An AESTHETIC and SUPERB Erongo Mountains combination specimen! A gemmy and lustrous, 3.7 cm, intense blue aquamarine crystal is jauntily perched on the side of a highly lustrous, doubly terminated, etched schorl crystal. The two crystals are beautifully complimented by a bit of microcline. Typical for many Erongo aquas, the termination area is extremely gemmy. This is an OUTSTANDING and pristine example of the species from this famous locality.
5.2 x 2.9 x 1.1 cm. A glassy luster and intricate stacking make this mini of schorl tourmaline really aesthetic.
4.0 x 2.5 x 1.8 cm. From the new find in the late fall of 2005 in Pakistan. This is a nice little specimen from the most famous Tourmaline locality in Pakistan. I have seen many Tourmaline specimens from Stak Nala for many years and the one characteristic of that many of them lacked was decent color. This crystal features several colors ranging from a slight colorless "Achroite" zone, grading into a blue-green area, then into an olive-green color, then a very dark forest-green color. The prism and pinacoid faces of the Tourmaline are rather lustrous for this material. To top it off, the crystal is associated with white "rosettes" of Albite (var. "Cleavelandite"). This is a great display piece and a wonderful pegmatite specimen from a classic locality. These pieces are becomingly increasingly difficult to find in today's market. Ex. Richard Kosnar Collection.
