18.4 x 4.9 x 3.9 cm. This big Montana smoky quartz has a fascinating termination. Part of the termination is typical smoky quartz; but about half-way over, it bevels out slightly into amethyst, which forms three of the six faces of the termination. This amethyst appears to be an overgrowth of complete smoky faces underneath, a sort of "cap" over half the termination. Ex. Richard Hauck Collection.
9.9 x 7.6 x 6.5 cm. The slender quartz crystals, with their rich coloration from rusty-red hematite, extend up to 7 cm from the base of platy hematite. Ex. Richard Hauck Collection.
2.9 x 2.7 x 1.0 cm. A fine floater of amethyst from Las Vigas showing the glowing purple color and gemmy clarity. Ex. Richard Hauck Collection.
8.8 x 8.8 x 3.9 cm. This is Indian amethyst - the side of a pocket walled with gemmy, bright purple crystals. Ex. Richard Hauck Collection.
7.9 x 4.8 x 3.3 cm. A beautiful example of Blanchard fluorite, with unusually deep and saturated "Blanchard Blue" teal color, along with unusual purple shading to some of the crystals, making it particularly attractive. The crystals measure to 1.4 cm on edge.
6.4 x 5.9 x 5.4 cm. What makes this Swiss quartz specimen so special is that there are two generations of crystals growth here -- a first generation of nice clear crystals, and then, wrapped around their bases, a later generation of slender, super-gemmy smaller crystals sticking out on all sides. Ex. Richard Hauck, Mitch Gunnell, and E. G. Tribbey Collections.
12.8 x 5.1 x 4.9 cm. This is a single large, complete, doubly-terminated crystal of transparent quartz from the Austrian Alps. Ex. Wein Collection.
5.1 x 4.8 x 3.5 cm. This is a cluster of amethyst crystals from North Carolina. One of them is really interesting, with a conventional termination on one end, and two equal-sized terminations on the other. Ex. Feist Collection.
3.4 x 2.2 x 1.9 cm, 2.9 x 1.5 x 1.4 cm. Two fine little sceptres from North Carolina, both with transparent terminations in perfect condition, one of them a phantom. Ex. Richard Hauck Collection.
10.5 x 8.4 x 8.2 cm. A large and fine North Carolina quartz out of the Feist Collection. The crystals have superb glassy luster and are very richly piled up. Also, there is this beautiful combination of smoky and amethystine hues, and enough clarity to the crystals that you can really appreciate this.
10.4 x 8.8 x 7.9 cm. A large and fine specimen of red quartz from recent finds on the Namibian side of the Orange River - not only showing the beautiful red color that some quartzes from there have shown due to rich hematite inclusions, but also showing dramatic sceptering. The red cap has wrapped itself around a colorless euhedral crystal that is clearly visible as the "stalk". This central crystal is surrounded by smaller accenting crystals of red quartz. Ex. Richard Hauck Collection.
4.9 x 4.9 x 2.8 cm. This specimen is from Wilkes County, from older finds - the piece came out of the Feist Collection. These two amethyst crystals are stacked atop one another, against a backdrop of colorless quartz. To make it more interesting, the amethysts are colorless in the middle, and purple on the termination faces. Ex. Richard Hauck Collection.
7.9 x 7.9 x 3.2 cm. A superb and beautiful plate of bright blue-green cubes of fluorite with what is identified on the label as "sugar quartz" - a pretty sprinkling of sparkly little beta-style quartz crystals. Ex. Ed. David Collection.
10.1 x 6.9 x 4.0 cm. What you have is a bent black schorl tourmaline crystal, distorted from pressure during growth in the pocket. At one end of his a cluster of parallel quartz crystals have formed, wrapping themselves around the schorl - and there is a little red spessartine to cap it all off.
22.9 x 20.4 x 12.2 cm. An unusual and fine Brazilian amethyst specimen: part purple amethyst, part colorless quartz in a starburst. The crystals are growing attractively towards a central point inside the pocket, and towards their terminations, the formerly milky quartz turns to a striking purple - as the solution inside the pocket changed to add the color, one supposes.
