A brilliant, lustrous, very 3-dimensional piece with sharp, fiery orange-red, 2-cm sphalerite crystals perched on brilliantly lustrous quartz crystals. This is a very fine piece. BETTER AND GEMMIER IN PERSON! 9.1 x 5.5 x 4 cm
This piece looks like a frozen river of brilliant pink rose quartz , preserved in a moment of time as it splashed across the under laying milky quartz. 7.5 x 6.2 x 5.4 cm
A large and showy plate with BRILLIANTLY gemmy and clear quartz crystals to 5 cm, perched against a backdrop of smaller quartzes and stark white, sharp adularia crystals. CLASSIC Swiss combo piece! 17.6 x 9.6 x 5.8 cm
3.9 x 3.5 x 3.0 cm. This piece features a sharp and robust crystal of babingtonite that looks like it was carved out of black onyx, it is so sharp and lustrous. The crystal is 2.4 x 2 x 1 cm in size and is perched right on the edge so you can see all sides, and both terminations. This specimen is the finest miniature for a single isolated crystal of babingtonite on matrix that I have seen from this recent startling find - which everybody I know agrees has now produced best of species. A lot of them were mined in the last 2 years and trickled out, but few have this lustre or perfection, or even the crystal size on matrix.
6.9 x 5.8 x 4.8 cm. An uncommon and beautiful combination specimen from the Tsumeb Mine. Sharp, euhedral quartz crystals are relatively rare from this historic mine, but this excellent piece is covered with a forest of glassy, translucent quartz crystals with a pretty, pink, oxide tint. A 9 mm, euhedral galena crystal is perched on one corner of the specimen and is a very nice contrasting accent. Scattered about on the quartz crystals are tiny, 1-2 mm, light brown wulfenites. Wulfenite on quartz is rare from Tsumeb. Ex. Rob Smith Collection, a noted Tsumeb specialist.
10.7 x 7.0 x 5.7 cm. The recent finds of amazonite and smoky quartz from the Smoky Hawk claim of Teller County are among the finest this historic district has produced. This fine cabinet specimen is an excellent and aesthetic example with top color. The lustrous, sharp, crystals reach 5.5 cm and have rich, turquoise-blue color. A couple of small smoky quartz crystals, tucked into clefts, are nice accents. Collecting by Adam Sotomayor, a well known local collector.
6.9 x 5.4 x 3.4 cm. A striking, gem-like, “Herkimer Diamond” quartz crystal cluster from the famous deposits at Middleville, New York. The large crystal is doubly terminated, as are several of the smaller "diamonds". The termination of the large crystal is razor sharp and is complete-all-around. The internal crazing and clay inclusions really add character to this aesthetic specimen. Ex. Daniel Trinchillo Sr. Collection.
7.4 x 5.4 x 3.7 cm. A fine smoky/amethyst quartz crystal from recent finds in the Goboboseb Mountains. This dramatic piece is very glassy and totally water-clear. The two terminations, unusual form, skeletal features, shading variations of the smoky color with subtle amethyst hints and clay inclusions are highly noteworthy. Every turn of this sharp crystal presents an entirely different perspective of the outside and interior of this stunning crystal. Complete-all-around. Highly representative for the species and locale.
6.0 x 5.5 x 3.0 cm. A classic and very beautiful, mounded hemisphere of glassy, lustrous amethyst crystals with vivid purple color. The tips of many of the amethyst crystals are particularly gemmy and the colorful, brick-red hematite inclusions are a classic accent. Expertly collected. Excellent, highly representative material from the famous Thunder Bay District of Ontario.
3.9 x 3.3 x 2.2 cm. The fabulously rich silver mines at Guanajuato, Mexico have produced some outstanding amethyst specimens and this is an excellent example. It is studded with glassy, pretty, lavender-colored amethyst crystals with subtle phantoms. Ex. Consie Prince Collection.
3.6 x 0.7 x 0.7 cm. A stunning and beautiful amethyst scepter from the famed Morchnerkar of Austria. The gem-like amethyst scepter, with fine, variable purple color is perched on the column of water-clear quartz. Pristine, the sparkly hexagonal specimen is a glory to look at in every face. Classic material.
6.8 x 6.4 x 5.5 cm. Classic, translucent, pretty "Blanchard-blue" fluorite cubes with purple highlights cover the undulating matrix of quartz on this fine specimen from the Blanchard Mine. The crystals reach 1.4 cm. Highly representative of the species and locale.
13.8 x 10.0 x 7.1 cm. A dramatic, two-sided, cabinet specimen of lustrous, colorless, drusy quartz stalactites from recent finds at Jalgaon, India. The striking, centrally-placed, large stalactite is 8.8 cm.
22.2 x 14.3 x 7.0 cm. Our Chinese sources have furnished us with another striking example of the mineral bounty of their country. This is a new find of carved and polished jasper picture stone from a less well-known area. This striking, two-sided, large cabinet piece has two outdoor, country scenes that look like Chinese murals. This is one of the reasons, why they are so popular in China. Art in stone. The measurements include the custom-made wooden base. Weighs 6.8 pounds or 3.1 kilograms.
8.3 x 5.2 x 3.8 cm. This is a very impressive specimen of Ferberite from Bolivia. The piece features several superb, sharp, lustrous, aesthetic, jet-black crystals measuring up to 4.2 cm across forming a beautiful "flower"-like crystal group associated with a gem Quartz crystal and minor Arsenopyrite crystals. These Bolivian Ferberites are often underrated and stand up well against any other Ferberites from China or Panasqueira. This piece was from the famous find in 1999 at Tazna.
