5.4 cm in largest dimension. A selection of four different specimens of citrine/amethystine quartz from Boekenhoutshoek. Each of them is "quartz on quartz" - two generations of crystals, sparkly smaller ones on large underlying crystals.
5.7 x 2.2 x 1.5 cm. A sharp, water-clear, smoky quartz crystal with a 3 mm movable bubble from the Goboboseb Mountains of Namibia. This very glassy crystal is pristine and the bubble moves over 1.0 cm. Ex. Richard Hauck Collection.
8.1 x 4.9 x 4.0 cm. Skeletal quartz (more popularly known as Elestial Quartz or Jacare Quartz) exhibits unique internal and external dissolution-growth features resulting from unstable conditions during crystallization. Skeletal quartz crystals often form with a geometric pattern of lines, depressions and raised terminations. This superb "Elestial" smoky quartz specimen has a multitude of glassy, water-clear crystals on the very sculptural, 3-dimensional quartz matrix. Rarely do you see an "Elestial" of this quality from the Spruce Pine District of North Carolina. Ex. Richard Hauck Collection.
8.0 x 5.9 x 5.8 cm. A fine Romanian specimen of two, "rabbit-ears"-looking, glassy, milky quartz stalks topped by quartz scepters on a matrix of smaller quartz crystals and sphalerite. The two scepters are pleasingly pristine and the specimen is nicely accented with a dusting of calcite crystals. This older piece is probably from the famous mines of Maramures County and hails from the Richard Hauck Collection. Sceptered quartz is rare in this quality from Maramures County and this is an excellent example.
14.3 x 9.5 x 8.5 cm. A dramatic and striking cabinet combination specimen of a "mountain" of snow-white, sparkly, sponge-like, etched hyalite opal on layered quartz and sulfide matrix coated with beautifully contrasting, lustrous, pink rhodochrosite crystals from the Santa Rita Mine of Peru. This is a very showy and highly unusual large combination specimen, as the opal, in this case, does not fluoresce. Ex. David Ellis Collection.
11.0 x 7.0 x 6.3 cm. A superb, 4.8 cm, translucent, sea-green, rounded fluorite octahedron aesthetically perched on quartz matrix from the Ed David Collection. The internal refractions within the fluorite are beautiful and there is even a touch of rose quartz (close-up) to the left of the fluorite. This outstanding cabinet piece is from the less well-known Kavalerovo Mining District, near Dal’negorsk, Russia. This is a much rarer locale for specimens than the nearby Dal’negorsk mines.
3.0 x 2.7 x 2.0 cm. A rare and aesthetic Chinese miniature of cinnabar included in a nearly transparent, glassy quartz crystal set in dolomite and quartz matrix from Tongren. The quartz crystal has a pleasing, very sharp termination that is very nearly pristine. Seldom do you see cinnabar included in quartz like this. Ex. J.R. Glover Collection and Richard Hauck Collections. Said to have come only from one pocket in the 1980s.
2.7 x 1.4 x 1.3 cm. The hardest crystals become the softest. A superb specimen of a super-sharp, complete all-around, pseudohexagonal, light brown, talc pseudomorph after a quartz crystal. This fine old-time specimen is from a renowned locality for this rare replacement - the Johannes Mine, Bavaria, Germany. The quartz pseudomorph is so sharp, that it looks man-made, but the beautiful patina is diagnostic, that it is, in fact, natural and not carved from a massive talc block. This is very old material. It once was called "steattite". Ex. Mullane Collection accompanied by a label in German.
4.0 x 2.2 x 2.2 cm. A very interesting combination specimen with Metatyuyamunite crystals gathered together in sheaves up to 3 mm associated with very small Carnotite flakes. The Carnotite is of a paler yellow than the Metatyuyamunite and not well crystallized. The minerals are sitting on a bed of Malachite. The Malachite sits in turn on Heterogenite covering Quartz crystals. Carnotite and Metatyuyamunite were rare minerals at Mashamba and the specimens where recovered in the mid 1980’s. As the Mashamba mine is flooded and most probably exhausted, no specimens will perhaps ever reach the market again.
8.1 x 4.1 x 3.7 cm. This is the largest enclosed brookite in quartz from Brazil that I have seen. It is an exceptional inclusion specimen, and within a beautiful (polished) quartz crystal. The inclusion is fully exposed, visible with no flaws. Surrounding the large 4-cm-long brookite is a halo of micro-thin acicular needles of rutile, silvery-colored, shooting out at all angles. Weighs 210 grams.
11.2 x 4.5 x 4.0 cm. This is a large quartz, very bright and lustrous, showing a dramatic scepter outgrowth atop the main stalk. Within are at least 4 small movable water bubble inclusions. They are interesting to watch as they move back and forth within the crystal, as you turn it around in your hand. The quality of the sceptre is very high, glassy and lustrous, and complete all around except for a small bit of edge wear on the top of the termination. Weighs 242 grams.
11.7 x 7.2 x 5.5 cm. This is a big quartz cluster with strange, satiny lustre and perhaps a partial dissolution effect that makes it look like running wax…in person the effect is quite pronounced. The subtle complexity of the surface makes it very interesting.
12.7 x 12.5 x 6.6 cm. Guimaraesite is a newly described complex calcium/zinc/magnesium/iron beryllium phosphate, which comes from an unnamed pegmatite working in this valley. This specimen is a complete floater quartz cluster the size of a large grapefruit, with exception only of one small bit on one side which is contacted. It is smothered on one side by Guimaraesite in sub-mm spherical crystal clusters. This is the first rich specimen I have seen. Described in 2006.
13.0 x 11.3 x 1.5 cm. A superb tabular quartz crystal, unusually thin and elongate, with mesmerizing geometry to it. The piece is water clear, and is a complete floater all around. Such elongated tabular quartzes seldom survive in this size range.
10.3 x 7.2 x 3.9 cm. A superb cluster of absolutely clear, limpid quartz crystals with the highest lustre, many slightly included by golden rutile needles within. The largest crystal is 4 cm.
