Extremely sharp crystals to 7mm, combined with unusually fine pseudocubic crystallography, makes this specimen a VERY choice miniature for the locality. These were collected, I am told, between the 1880s and 1920s. Most such specimens are rather lumpy, less rich, or simply have more poorly developed crystals. For the market, this is a very special and choice specimen....as you'd expect from the German suite of this particular collection, which was clearly its pride and joy.
A rare locality piece featuring a 1.1 cm, bright chalcopyrite crystal perched atop lustrous white quartz and dolomite crystals.
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 to the whole specimen.
This large plate of lepidolite has a lot going for it. It appears that there may be two generations of lepidolite, the first one being dark sulfur yellow and composed of interlocked crystals, to 2.0 cm across. The second generation has rosettes of light sulfur yellow, translucent, crystals, to 1.25 cm across. The piece de resistance is the cluster of parallel growth, slightly smoky, gemmy, quartz crystals, 6.0 cm in length, located at the left edge of the specimen. This is a major lepidoloite specimen!
This is a near floater, with the only point of attachment being at the base of the quartz crystal. An etched and frosted, colorless quartz crystal, 4.0 cm in length, is perched at the top of the translucent, light sulfur yellow, lepidolite specimen. The lepidolite has formed in rosettes, up to .75 cm in length.

This remarkable specimen is one of the finest hematites recovered from England, for crystal quality, according to both Ralph Sutcliffe and Lindsay Greenbank (who should know!). It is not just specular, druse material as is commonly seen - but features real, sharp, disclike crystals. The lustre is fantastic, like black mirrors. Atop these brilliant blades hangs like decoration a row of sharp quartz crystals of the unusual habit so desirable and unique to this mine (sometimes called beta quartz-like in form). All is atop a thin rind of hematite "kidney ore." This piece was the best specimen of a small pocket blasted into in 1978, by Raymond Clements. He was at the time the underground mine surveyor for this company and selected this specimen for his own collection, while the rest were sadly destroyed. It is very difficult to convey in photos how sparklign and vividly color contrasting this specimen really is, but the piece, winglike in its stretched-out appearance, is stunning in person.

Super sharp, unusually vertical crystals to 8mm on rare matrix

Superb pair of doubly-terminated, very lustrous Amethyst crystals from the famous locality of Thunder Bay. Each crystal is 2.5 cm in length. What is so rare about these, in addition to the unusual red coloration due to included Hematite, is tha fact that these Amethysts are doubly-terminated. In fact, both are DT'd, and virtually pristine. One of the most aesthetic specimens I have seen from Thunder Bay in any size

A sharp, lustrous, deep green Uvarovite garnet crystal with excellent emerald-green color from the famous Outokumpu Mine of Finland. The sharp, 1.2 cm crystal has textbook dodecahedral form and is in remarkably good condition. Uvarovite is the calcium chromium garnet group end member. This is a classic specimen from a premier locality, with a relatively large crystal. It makes for a very aesthetic thumbnail

Outstanding, and truly first-tier, combination piece of a fabulous Anatase balanced upon a gemmy, pristine, Quartz crystal. Normally, the Anatases you see associated with Quartz are less than 1 cm, but this lustrous, euhedral bipyramid is an astounding 2.7 cm in length. The presentation faces are shiny, striated, and very sharp. There is some contacting on the base of the reverse side, but that is where it grea against matrix and it is otherwise complete. Considering the sharp, gemmy Quartz, and the magnificient Anatase-of-huge-size, this is just a killer! To me, it is one of the finest pieces in this collection. It is a toenail sized specimen (either a large thumbnail or a small miniature depending on how you angle it for display) ex Sam Nasser collection. Specimens like this are stunning examples of this unusual species, seldom seen. it is top tier.

The Messina Mine is home to these unique, and beautiful, Quartz crystals included by the rare copper silicate, Ajoite. The first generation of Quartz is richly coated by the Ajoite, and the second generation Quartz then preserves it as a wonderful turquoise-blue phantom within. And , these are doubly-terninated, no less. Rarely will you find one of these combination pieces in such good, aesthetic, quality;AND in a thumbnail size!

Stunning, GEMMY, 2 cm champagne Topaz, on Quartz and Mica matrix, from the famous mines of Gilgit. To find such a quality crystal on matrix, is quite unusual. It is pristine on display face, slightly contacted only on back. The topaz is a JEWEL! The pics tell the story. Elegant, and a killer.

Outstanding pair of large (up to 3.5 cm) very dark and highly lustrous twinned Sphalerites. Combined with the distinctive long and slender Quartz crystals, this makes a wonderful combination. Very aesthetic, and better in person.

Distinctive and dramatic pair of ‘rabbit-ears’ Amethyst crystals, with good color and perfect form. The surfaces are gently frosted, which create a softness to the specimen that adds even more appeal. Shown strongly lit and with minimal backlighting.

A beautiful cluster of deeply hued superb Amethyst crystals, the two largest being over 5.5 cm in length. These gemmy crystals have fine purple upper halves which grade into a very fine smoky quartz in their lower halves, and the terminations are skeletal. Brandbergs have a well-deserved reputation as being high-quality amethysts, and these are certainly in that tradition.
