A nice-sized, impressive specimen consisting of sharp, transparent quartzes tinted at their tips with hematite, with minor bladed hematite at the base. The matrix provides a “foreground” for the quartz crystals, and overall the specimen is wonderfully balanced. Only one ding on one of the crystals, so in very good shape and just really pretty for a Chinese quartz. 8.5 x 8.5 x 8 cm
18.2 x 6.2 x 1.8 cm. Here is a very large and complete smoky from this unusual locality, with unusual flattened form, and striated faces. It is complete all the way around, and terminated sharply on top. The back 2 faces have bits of mineral attachment. Ex. Richard Hauck Collection.
8.4 x 4.6 x 2.1 cm. This is a very unusual doubly-terminated floater crystal (with a smaller crystal attached); the crystals have good transparency and luster, and the distinctive acid-yellow color peculiar to Russian citrines.
5.3 x 5.3 x 2.4 cm. This is an older Georgia amethyst from this locality, consisting of a beta-style crystal with smaller crystals having grown at its base, leaning off of a shard of quartz-covered matrix. Ex. Richard Hauck Collection.
17.2 x 8.8 x 7.9 cm. You mostly see these "blue stripe" kyanites as single crystals. Here is a large specimen with over a dozen of them, to 8 cm, embedded in the quartz in which they formed. The blue color is lighter in person.
7.4 x 3.9 x 3.4 cm. A superb example of Brandberg amethyst at its best - with glassy clarity, internal anomalies that cause the crystal to throw off dazzling reflections, and a blend of both smoky and amethystine colors. Ex. Richard Hauck Collection.
7.8 x 4.2 x 3.9 cm. Here is a very gemmy and fine aquamarine crystal of 3.5 cm, with little schorls grown into its surface, lying along the matrix surrounded by both sharp little smoky quartzes and wonderfully glossy, chunky little schorls.
4.6 x 3.5 x 3.3 cm. From the collection of Carlton Davis, an unusually glassy crystal of smoky quartz from the classic Butte locality. Good transparency.
19.3 x 9.4 x 7.3 cm. A large, gorgeous Chinese specimen out of the noted collection of Ed David. What you have is an amazingly elegant cluster of quartz crystals, with gemmy flattened crystals of baryte that have attached themselves attractively to the crystals. Anchoring the specimen, in back, is an 11-cm quartz crystal. Sticking forwards towards the front are superb quartz crystals with an amazing perfection to them - perfect symmetry, a very gradual taper, and a slightly silky luster.
VERY uncommon on the market, a large South Carolina amethyst (the largest crystal is 6 cm tall and 3.5 across) with good color, form and sharpness. Most of the lower terminations are intact in addition to the top ones. There are some contacts, but this is really a fine piece for the locality. 7 x 6.2 x 4.5 cm
12.8 x 5.9 x 4.1 cm. Rather than a small cluster of crystals, this is a huge naturally-etched single crystal. It has light pink color. There is a really strange and interesting anomaly in this crystal: just under the surface is a layer of round, conical etch pits that were once on the surface of the crystal, but were enclosed later as the crystal re-started growth. Ex. Richard Hauck Collection.
6.6 x 3.4 x 3.3 cm. Here, you see the crystals of eosphorite displayed on the termination of a milky quartz crystal that is covered with sparkling crystals of rose quartz. Ex. Joe Freilich Collection.
14.8 x 10.2 x 7.4 cm. A rare large cluster of French quartz, featuring long, slender, elegant crystals to 6 cm in length. Ex. Richard Hauck Collection.
12.3 x 3.3 x 2.8 cm. Here is a magnificent tower of stacked, gemmy crystals with the faden line clearly visible running through the crystals from top to bottom. Note how the top two crystals are canted at an angle, sitting atop the vertical bottom crystal which forms a sort of natural and pretty "base" or pedestal for the specimen.
12.8 x 9.3 x 5.8 cm. This specimen has fine smoky quartz crystals with glassy luster, in addition to two pretty forms of feldspar - large euhedral crystals in one area, and surrounding the smoky quartzes, small platy translucent crystals.
