9.0 x 8.3 x 8.0 cm. A 5.0 cm, euhedral, deep green emerald crystal is frozen in massive green quartz along with fragments of other emerald crystals in this fine specimen from the Carnaiba Mine of Brazil. While these crystals certainly are not as gemmy as good Colombian ones, note that this is an old Brazilian emerald specimen - far rarer. Highly representative of the species and locality.
12.2 x 8.0 x 4.5 cm. Lustrous, coloress, nail-head calcite rhombs to 3.5 cm richly and attractively cover the cabinet quartz matrix on this fine, old-time, cabinet, combination specimen from the iron mines of Cumbria, England. This is classic combination material from this renowned locale. Probably old, but no telling how old. Ex. Russell Jones Collection. Outstanding pink fluorescence.
7.7 x 7.3 x 4.0 cm. Papagoite is a very rare calcium, copper silicate. This striking, porcupine-like cluster of quartz crystals has many termination areas richly and beautifully included with bright blue papagoite. This specimen has exceptionally rich coverage of papagoite in so many crystals. Most Messina specimens are single quartz crystals included with papagoite. I have not seen another like it from this locale.
7.7 x 4.5 x 4.0 cm. A fabulous, old-time Montana specimen from the Richard Hauck Quartz Collection. Multiple, gemmy amethyst scepters with vivid color, are very aesthetically perched atop a glassy, stepped-faced, opaque smoky quartz crystal. The scepters are superb, pristine, and doubly terminated. This piece is from the very uncommon Little Pipestone District of Jefferson County. The George English label dates the piece to 1899-1901. The Art Mongomery label dates to 1936.
12.9 x 7.8 x 7.6 cm. Gillette tourmaline is rare enough - an example on matrix rarer still, and a specimen with multiple tourmalines on a crystallized quartz…nearly unheard of. This small granite pegmatite quarry, worked for decades in the early to mid 1900s and now covered by development, produced some classic East Coast tourmalines. The larger tourmaline has one repair, and measures 3 cm long. The smaller tourmaline next to it has one clean repair as well. The quartz has a shard repaired lock-fit where it slid off the remainder of the crystal right over the tourmaline pocket, set over the tourmalines, where that piece of the quartz was knocked off. Ex. George Elling Collection.
3.7 x 2.4 x 1.3 cm. An outstanding miniature of sharp, well-defined Dioptase crystals on a Quartz matrix. The Dioptase crystals range up to 1.1 cm in length, and have superb luster and color. What makes this so incredibly special, though, is how well the Dioptase crystals stand up on matrix. Ex. Charlie Key.
4.3 x 3 x 2.7 cm. An alluring single Amethyst crystal on drusy quartz matrix. This beautiful and gemmy single rises 1.4 cm above the matrix, where you can see and appreciate every lustrous face and every deep purple zone. For something so simple, it is simply elegant. Ex. Charlie Key.
6 x 6 x 4.2 cm. A stunning "geode" composed of a complete crust of beautiful blue Shattuckite, .4 cm thick all the way around, accented by Malachite and Quartz. The opening is 4 x 2 cm, and 5 cm deep. The vivid blue on the outside is contrasted to the sparkling stark white inside, as the thin quartz layer has covered shattuckite inside the vug. It sparkles like sugar. Ex. Charlie Key.
6.2 x 4.5 x 4.1 cm. A remarkable combination of Hematite-included Quartz draped with numerous zoned purple Fluorites. The sharp and gemmy Quartz crystals range up to 2 cm and the Hematite zones within are superbly defined. Add to this the numerous zoned purple octahedral Fluorites, gemmy and .6 cm on edge and you have a very unusual and highly aesthetic piece. Ex. Charlie Key.
10.5 x 8.5 x 8 cm. An outstanding single, doubly-terminated Quartz crystal the likes of which I have not seen from the Erongo region. This giant 10.5 cm crystal is perfectly gem-clear, with a glass-like luster. It looks like a topaz and I would be fooled if not for the hardness test we did on it. The termination is complexly etched by solution effects. Ex. Charlie Key.
11.5 x 8.5 x 5 cm. A fine specimen of gemmy, lustrous Dioptase from the Kaokoveld Region. The largest of these "gems" is 1.5 cm, and they flash a brilliant green in the light. Contrast is enhanced by the powdery blue coating of chrysocolla, all on a quartz matrix. Ex. Charlie Key.
7.8 x 5.5 x 4 cm. An exceptional 6 cm, doubly-terminated Apophyllite perched beautifully on a stalactite of sparkly gemmy Quartz crystals. The Apophyllite has a gemmy main termination, and the luster is superb. The smaller 1.8 cm Apophyllite is also gemmy and lustrous, and it complements the larger crystal in striking fashion. Ex. Charlie Key.
7.1 x 5 x 2.8 cm. A superb ball of translucent-gemmy curved Epistilbite blades that have grown together to form a ball nearly 3 cm across. The luster is excellent. It rests on a plate of excellent, gemmy medium-purple Amethyst crystals. Ex. Charlie Key.
3.7 x 3 x 1.8 cm. A very complex, gemmy Fluorite octahedron on Quartz from the Erongo region. The Fluorite is light green (with some light Hematite staining for contrast) and highly modified in habit. The crystal is an octahedron with stepped faces and corners modified by the cube. Each corner looks like an Aztec pyramid. The crystal is gemmy, and the Quartz crystals below make an attractive complement. Ex. Charlie Key.
9.4 x 5.4 x 4.2 cm. Classic Tongbei - Smoky Quartz crystals generously covered with gemmy Spessartine Garnets. The largest Smoky Quartz is 2.5 cm in size, and all have good color and luster. The beautiful Garnets are gemmy, deep orange, and have the superb, striated luster that makes them so special. An excellent, aesthetic specimen. Ex. Charlie Key.
