4.9 x 1.9 x 1.4 cm. This glassy (in person) quartz crystal is decorated with colorful little crystals of iridescent pyrite, as well as micro lavender fluorites, with a really beautiful result!
8.2 x 6.9 x 5.5 cm. I like to call this sort of luster "mirror-metallic" - it is just fantastic. These crystals, to 1.8 cm, also have all sorts of interesting growth modifications - hoppering, skeletal growth and corner bevels amongst them. You can see some accenting quartz crystals in between the galenas here and there. A fine Eastern Euro galena!
8.6 x 1.9 x 1.8 cm. This is an absolutely STELLAR Lincoln County smoky. It rivals a top Swiss crystal in every way - luster, clarity and sharpness. There is even a subtle phantom inside! The color is slightly "blushy", like a Brandberg quartz. Ex. Marty Lewadny Collection.
6.3 x 1.8 x 1.4 cm. This find of around two years ago in Madagascar was just so exciting - because rarely do you get inclusions as striking and dramatic as this. Inside this clear quartz crystal, you can clearly see three purple fluorite crystals (one of them smaller than the other two) that formed on the surface of the quartz crystal as it was growing, and then were engulfed when the quartz continued to grow after that. Now there they are, floating mysteriously inside the quartz! This one is in great shape, too.
4.8 x 4.1 x 3.3 cm. A complete, complex and beautiful spinel-twinned galena from Eastern Europe, standing beautifully on its side, accented with gemmy quartz crystals. This galena twin is complete on both sides and edges. If you look closely you can see complicated hoppering and wave-like tiers on some of the faces. Wonderful example of this twinning phenomenon in galena!
4.1 x 3.3 x 1.3 cm. A cute and aesthetic two-sided cluster of highly lustrous, divergent sprays of olive-green epidote crystals from the recent and small find in Afghanistan. The little quartz needle at the end is a neat accent. Essentially pristine, with only a couple of points of attachment.
4.0 x 2.9 x 2.7 cm. Ajoite is a VERY RARE copper-related silicate. This is a KILLER, UNPOLISHED, natural quartz crystal that displays RICH zones of concentrated, turquoise-blue ajoite inclusions that you can ask for, and is about the most ajoite I have ever seen in one crystal. Truly an exceptional miniature by ANY standard for the collector of all things quartz, copper or South African. This super piece is from a RECENT, very small find from the famous Messina Mine of South Africa, source of the VERY BEST ajoite-included quartz crystals. The ajoite phantoms are FABULOUS! The termination is pristine and a bit of contacting on the back on one corner is noted, but is certainly are not a visual detraction to this gorgeous and unique specimen. Essentially complete all-around.
5.5 x 3.7 x 3.2 cm. A SHOWY and EXCELLENT Erongo Mountains combination specimen of two, very gemmy and lustrous, mostly colorless topaz crystals in parallel growth aesthetically set in spires of glassy, water-clear smoky quartz. The bit of edge wear at the large smoky termination is barely noticeable. The topazes and smokies have amazing transparency. Excellent material, complete on three sides, from the Dave Mansfield Collection.
6.5 x 1.8 x 1.2 cm. A beautiful, glassy, unusually doubly-terminated amethyst crystal from Brandberg. This sharpy is pristine and unusually flattened. Ex. Dave Mansfield Collection.
5.3 x 4.4 x 2.4 cm. This well-balanced matrix galena specimen is covered by a bed of green, chloritic to colorless, gemmy, lustrous quartz crystals, to .75 cm across. Perched aesthetically on the quartz are three lustrous, skeletal, battleship-gray galena crystals, to 2.5 cm across. They are more elegant than boxy, if that makes sense to say, though they are technically box-work in form. It appears that the largest crystal was octahedral in form rather than the more ubiquitous cubes. Truly dramatic and unusual! More 3-dimensional in person, too!
7.4 x 5.0 x 3.7 cm. Gemmy quartz crystals, some doubly terminated and chloritic, are the matrix for skeletal, lustrous, battleship-gray galena crystals to 1.6 cm in length. A few, small brassy yellow, chalcopyrite crystals abut the galena crystals, on the back side of the specimen. I particularly like the way the galena crystals are perched high on the matrix, very dramatically.
8.4 x 6.0 x 4.3 cm. Note this is one of the largest specimens recovered in good condition, with any aesthetics to it; and is also particularly balanced and well-trimmed. The etched, skeletal, battleship-gray galena crystals are beautifully perched on a matrix of colorless quartz, with nearly all of them exhibiting amazing etching to their hollow cores, where only the crystal edges remain. Magnificent and aesthetic for the rich contrast to quartz!
12.2 x 7.3 x 4.3 cm. Gorgeous rolling plate somewhat translucent and very sparkly, on quartz karst matrix.
9.6 x 5.7 x 3.7 cm. A beautiful, curving specimen of nearly solid amethyst, translucent.
10.7 x 5.6 x 5.0 cm. One of the best in the lot for its undamaged, 3-dimensional, rolling surface and intense coloration! It has great form, and is complete on the front as shown, contacted just on the sides.
