3.6 x 2.9 x 1.5 cm. This is the "classic" combo that all collectors know of from Erongo: aquamarine and schorl tourmaline. With this specimen from the collection of Marty Zinn, you have an aquamarine that is UNUSUALLY fine and gemmy for the locality - they typically are no competition for the more common Brazilian and Pakistani aquas, but this one is truly gemmy. And, it is doubly-terminated to boot! The crystal sits on a "base" made up of another aquamarine crystal, some feldspar and a schorl crystal.
4.2 x 2.5 x 2.2 cm. A BEAUTIFUL, CLASSIC and OLD-TIME combination specimen from the famous Little Three Mine of San Diego County of a 1.0 cm gemmy and lustrous, orange spessartine garnet aesthetically attached to the side of a lustrous, jet-black schorl crystal with an etched termination. The schorl is exquisitely wrapped in contrasting, floral-like, bladed cleavelandite. This complete all-around beauty dates to the 1960s and is from the Norm Dawson Collection, owner and operator of the White Queen Mine from 1948-1992.
8.6 x 6.3 x 6.0 cm. A MAGNIFICENT and STUNNING cluster of large, polychrome tourmaline crystals from a RECENT find at Stak Nala, Pakistan. These gemmy and lustrous crystals grade upward from deep green to yellow-green to yellow to colorless to pink! The color variety in each crystal is dramatic, as is the variable size of the crystals! The tourmalines are beautifully complimented by well-placed clusters of snow-white, bladed cleavelandite. Ex. Gene Meieran Collection.
10.5 x 5.9 x 5.3 cm. Seldom do you see aquas from anywhere but Shigar in Pakistan with such lustre to them, and color at the same time. This is an intensely blue crystal that looks richly included by albite in the photo, but ACTUALLY you are looking right through 2-inches of almost totally transparent, gem-grade, mostly clean crystal to see the little albite rosettes on the BACK of the specimen, here. The crystal cluster is complete all around 360 degrees, without damage. Also, its a floater...meaning it broke off in the pocket at some point from the "mother rock" and solution healed over the break on the bottom, as well - so it’s doubly-terminated although the bottom termination is flat and dull compared to the top. Lastly, it’s a very interesting piece visually because of the curving "phantom" zones within both crystals caused by albite and schorl inclusions during growth of the top zone. The terminations are lustrous and window-clear. Weight is 385 grams.
4.8 x 3.4 x 3.1 cm. The "classic" Erongo combo, aquamarine and schorl, with the aquamarine represented here by two DOUBLY-TERMINATED crystals, one 3.5 cm and the other just under 4 cm, in association with glossy black crystals of schorl tourmaline. One of the aquas lies attractively right on top of the large schorl!
13.3 x 6.5 x 4.8 cm. A STUNNING and DRAMATIC CABINET combination specimen from Paprok, Afghanistan. Two, parallel-growth, lustrous schorl crystals have striking, gemmy, indicolite-blue terminations! The schorls are beautifully and aesthetically accented by gemmy, water-clear, smoky quartz crystals and wrapped in snow-white albite. This is an outstanding, essentially pristine, complete all-around combo piece, with only minimal contacting at the base, on the back and out of sight from this famous locality.
2.8 cm. A complete all-around, lustrous schorl crystal with a sharp, pyramidal termination. Ex. George Elling Collection.
3.0 x 2.8 x 2.0 cm. A fine Stak Nala specimen of a gemmy and lustrous, polychrome tourmaline perfectly set at the junction of two, water-clear quartz crystals. Ex. Steve Smale Collection.
7 x 5.7 x 2.4 cm. A fine coating of dozens upon dozens (maybe hundreds) of gemmy .3 cm Herderite crystals on a rich nest of intergrown Schorl crystals. The Herderites are gemmy, lustrous, striated, and have the faintest tint of light green. The Schorls are about .8 cm and highly lustrous. They are so sharp and shiny that they maintain their individuality. Ex. Charlie Key.
6.6 x 6.3 x 4.6 cm. A superb cluster of six doubly-terminated Aquamarine crystals intergrown with Orthoclase and a beautiful lustrous Schorl crystal. The largest of the aquamarines is 4 cm long, has excellent luster and sky blue color, and a clear gemmy .5 cm termination. Ex. Charlie Key.
4.7 x 3.2 x 2.7 cm. A superb cluster of lustrous striated Schorls. Each crystal has fabulous luster, sharp attractive vertical striations, and the less-common trigonal terminations. The largest crystal, which is 2.7 cm tall and 2.2 cm across, is complete all the way around. Ex. Charlie Key.
5.5 x 3 x 2.5 cm. This 2.7 cm Fluorite is purple throughout, translucent, and a modified octahedron. Beyond that, it is included by hundreds of silvery needles (mineral unknown). The Schorl is lustrous and striated. Ex. Charlie Key.
5.1 x 3.9 x 2.4 cm. A fine example of beautiful Hyalite Opal. These two lustrous and gemmy masses, up to 1.5 cm across each, sit atop a matrix of Feldspar and Schorl. The light green color, glassy luster, and gemminess are superb. Intensely fluorescent. Ex. Charlie Key.
5.5 x 4.8 x 3.1 cm. A really complex combination piece, with an aquamarine shooting straight up through the crystallized albite feldpsar matrix (you can see it extend from underneath) like a fiber-optic cable of gem blue glass that transmits light from below if you shine it up. On this aquamarine is perched, as a wraparound, a spessartine garnet crystal that is pretty good on its own merits; plus the bonus that it is set up like a flag above the sharply crystallized white background. The terminated zigzag schorl at the base is a final bonus. Ex. Helmut Bruckner Collection.
7.9 x 7.5 x 5.9 cm. A large, rich cluster of fine, sharp aquamarine crystals and jet-black schorls, from the Erongo Mountains. All terminations are complete. The largest of the aquamarines, 3 of them, measure around 2.5 cm in length. They have a fine balance with the schorls, and both sit on a nicely contrasting tuft of stark white matrix. Ex. Marshall Sussman Collection.
