An exquisite toenail specimen of amethyst from new finds in Veracruz! Four crystals (to 2.5 cm) sticking up in different directions from just the right amount of matrix. 3 x 2.5 x 2 cm
A very aesthetic quartz specimen with two generations from the Idarado Mine of Colorado. Etched, frosted, striated and translucent quartz spires to 8 cm "protect" a "nest" of smaller milky-white quartz crystals. This piece is a FLOATER and is damage-free! Ex Gene Meieran Collection. 10.0 x 9.4 x 7.3 cm
An extremely unusual and uncommon specimen of chalcedony replacing blocky aragonite crystals from the Big Bend Area of Texas! Ex Betty Llewellyn and Marty Zinn Collections. Betty was Martys mother. Old material, as the label and pedigree attests. 6.5 x 6.2 x 5.4 cm
A very dark, highly lustrous, striated and preferentially etched hexagonal smoky quartz crystal from a very uncommon Fresno Co., California location, Dinky Creek. The crystal is complete on four sides and contacted on the other two. A trivial bit of termination damage certainly does not detract from this striking specimen. Ex Gene Meieran Collection. 9.7 x 5.1 x 4.3 cm
A showy CABINET-sized, old-time classic from the iron mines of Cumbria, England. Lustrous, hematite-tinted quartz crystals to 7 mm rest on a coating of specular hematite, which coats botryoidal hematite kidney ore. Nice! 11.0 x 6.1 x 4.3 cm
A 1 cm anhydrite crystal completely included within a quartz point! Unusual! 5 x 3 x 2 cm
A sharp hexgonal moly crystal perched front -and-center on a pedestal of massive quartz. NICE! 2.7 x 2 x 2 cm
11.0 x 9.7 x 6.4 cm. A large specimen with two kunzite crystals, both terminated on the end. The larger, chunky one measures 4.5 cm and is 1.7 cm thick. The other measures 2.5 cm, with less color but nicely transparent. A good example of this modern classic on matrix.
A superb cluster of two crystals, with one growing literally right out of the termination of the other, at a slight offset to the side. Weird and not your normal Arkie quartz! 9.5 x 2.5 x 2.5 cm
An exceptional example of Mexican Tennantite , with sharp lustrous crystals to 2 cm that rival the quality of recent finds in Kazakshtan! The fact that they are perched on a nice quartz cluster really makes them much more displayable than usual (usually the are just on flatplates of drusy quartz). 7 x 7 x 4 cm
An unusually large and sharp pseudo for the location, where such replacements tend to be rather ugly , for lack of a better word. Not only is the crystal somewhat attractive, but it is on attractive matrix besides! The galena measures about 4 x 4 x 3 cm and is crystallized with octahedral modifications on each corner. It is partially replaced by the anglesite (some galena is obvious internally from a cleave on the lower-bottom face, though all other sides are undamaged. The specimen is invisibly repaired about the midppoint of the matrix, with the galena-bearing half joined back to the left half. I did not even notice this when I bought it from an old collection at the Detroit show, to tell you how little this bothers me in terms of aesthetics. fOR DISPLAY PURPOSES AND JUST ITS INTEREST VALUE, THIS IS DARNED GOOD! 7 x 5 x 3.5 cm
Gorgeous calcite rhombs with shimmering surface luster and NO damage perched amongst quartz needles. The crystals are situated in such a way as to create a perfect display face for the specimen, with the largest crystal (2.5 cm) crowning the specimen. 5.0 x 4.3 x 3.6 cm
6.3 x 1.2 x 0.9 cm. A fine, doubly terminated, water-clear quartz crystal highlighted by preferential inclusions of epidote in the center of the piece and smaller quartz crystals. The double termination at one end is striking. The large quartz crystal is damage-free and the small quartz has one healed termination and one broken termination. From recent finds in Baluchistan, Pakistan.
7.2 x 4.7 x 4.7 cm. Gemmy and glassy, green ludlamite crystals richly fill a vug in crystallized quartz matrix on this fine specimen from the old and well-known Wheal Jane Mine of Cornwall. Exceptionally gemmy for the species and locale. Accompanied by a label in German indicating that the piece was collected in the 1980s during a brief reentry and mining for tin at Wheal Jane.
2.5 x 2.4 x 1.4 cm. Interconnected, sharp, lightly iridescent, tetrahexahedral copper crystals with a nice patina on quartz form an aesthetic and sculptural thumbnail from the less well-known Gratiot Mine of the famed Michigan Copper Country. Ex. Dick Jones Collection.
