7.3 x 3.7 x 3.6 cm. A superb large (3.4 cm) Stilbite perched on a delicate series of Quartz stalactitic straws. All the Stilbites have a lovely peach color and excellent pearly luster. Ex. Steve Smale Collection.
9.7 x 7.2 x 4.3 cm. Interesting and attractive cluster of Apatites coated with Pyrite, all on Quartz. The Apatites are a lovely grey-blue in color and have good luster. They are partially gemmy, but what is so unique are the Pyrites that coat two of the Apatites faces, particularly the largest 2 cm crystal. Ex. Steve Smale Collection.
5.8 x 3.3 x 2 cm. Lustrous and gemmy Smoky Quartz pair. The luster is superb, as is the gemminess. Ex. Steve Smale Collection.
10.4 x 6.4 x 3.4 cm. You do not see much material from the Pack Rat Mine (the California one, that is) around on the market. This piece came out of the Houser collection. It is a plate of modified prismatic and tabular quartz crystals, with a sprinkle of red spessartine garnets, on a matrix of albite.
5.4 x 4.0 x 3.7 cm. Beautifully gemmy and lustrous, pink roselite crystals line the floor of a 9 mm vug in quartz matrix on this fine OLD-TIMER from the Erzgebirge of Germany. Roselite is a RARE arsenate and this is a good one. The accompanying label, in German, says that the piece was found in 1874!! 133 years old! Ex George Elling Collection.
15.9 x 15.6 x 10.6 cm. An incredibly striking amethyst specimen, actually a lot better in person, since the deep, gemmy purple that you see only in these Uruguayan (and perhaps Russian) amethysts did not come through completely in the photos. This is a complete, perfectly rounded knob, covered all around with these glassy, gemmy crystals. The matrix was carefully trimmed out to form a perfect natural base for this amethyst "cactus". A large and captivating showpiece specimen that is one of the few of these i regard as a real specimen, and not just a decorative rock!
8.8 x 3.5 x 3.1 cm. I thought this was just a very fine Brandberg amethyst, till I flipped it upside down and saw a bubble inside a water cavity move around over a centimeter inside the crystal! These "enhydros", water trapped inside crystals in which occasionally are moving bubbles, are one of those weird tricks of nature, and make any crystal highly prized by collectors. But in this case, even without the crystal, you would be looking at a superb, large and complete crystal from a highly desirable locality. It has what makes these so unique: an isolated purple blush right in the center of the gemmy interior, and smoky color in a different area. The crystal has sharp faces and is complete all around, with the only contact being at the very bottom tip.
5.6 x 5.4 x 3.3 cm. This wonderful Namibian specimen of tourmaline crystals with smoky quartz crystals is a matrix-free floater! What is more, all but one of the terminations on the tourmalines is complete, and all the smokies are complete and doubly-terminated as well! The tourmalines range up to 4.8 cm in length, and are a deep gemmy green with pink at the tips.
8.6 x 4.6 x 3.9 cm. From the exciting find last year -- sharp, gemmy quartz crystals decorated with lustrous, deep moss-green crystals of epidote. The epidotes here are arranged in a ridge along the middle of the quartz crystals. One of the quartzes has actually engulfed some of the epidotes at its termination!
8.9 x 5.5 x 3.9 cm. The matrix here is completely carpeted with super-gemmy orange spessartine garnets, with a wonderful glassy luster! One lone smoky quartz crystal is at the edge of the specimen. The crystals have intergrown to form tightly-massed domed forms.
6.2 x 3.5 x 3.0 cm. A HIGHLY UNUSUAL and excellent, multi-colored tourmaline from the famous Himalaya Mine. This old-time piece has good lustre and gemminess and has a matte green termination, grading downward to pink, to rose-red to olive green. The lustrous smokies on the side are exceptional. Weirdly, on the back, are a 2nd generation host of very gemmy and lustrous, parallel-growth, light green tourmaline crystals. A truly uncommon and showy Himalaya combo piece. Ex. George Elling Collection.
11.0 x 7.5 x 5.8 cm. Emerald-green, gemmy and lustrous pencil tourmalines to 4.5 cm are aesthetically embedded on and in this IMPRESSIVE CABINET smoky quartz crystal from the Pederneira Mine. Yes, this large, euhedral smoky crystal is partially frosted and etched, but it is SO DRAMATIC.
2.5 x 2.1 x 2.0 cm. An AESTHETIC thumbnail specimen of the RARE carbonate weloganite, from the Type Locality - the famous Francon Quarry of Montreal, Canada. A 1.3 cm, sharp, hourglass-shaped, hexagonal, light gray weloganite crystal is very jauntily perched on matrix, like a smokestack and is nicely accented with quartz. A very fine representation of this rare and desirable Canadian species.
8.2 x 7.0 x 4.8 cm. This specimen is a great small cabinet size piece consisting of super quality, sharp, gemmy, lustrous, prismatic, light purple color "reverse" scepter and simple prisms of Amethyst measuring up to 2.3 cm sitting atop white/colorless, modified scalenohedra of Calcite on forest-green "Chlorite" on matrix.
3.7 x 3.0 x 2.5 cm. These new Spessartines are some of the most attractive and highly displayable specimens to come out of China in the last few years. This particular piece features several lustrous, gemmy, reddish-orange trapezohedra measuring up to 4 mm associated with highly lustrous, gem quality Smoky Quartz crystals. The color in these crystals is a rich orange hue (due to nearly pure Manganese content) and is very attractive.
