4.7 x 3.2 x 2.6 cm. A unique and pristine Brazilian quartz specimen from the Richard Hauck Quartz Collection. A water-clear, sharply pseudo-hexagonal quartz crystal is very pleasingly included with pink montmorillonite. The montmorillonite is distinctly zoned with the quartz, giving a very dramatic effect. A super quartz crystal with unusual inclusions!
7.0 x 5.0 x 2.7 cm. A dramatic and excellent Chinese specimen of a splendent 1.7 cm, bournonite crystal jauntily angled amidst a nest of water-clear quartz crystals from recent finds at the famous Yaogangxian Mine. The vug rests within a sawed milky quartz matrix. A beautiful and displayable combination specimen.
7.5 x 4.8 x 4.1 cm. An old-time, classic and showy Cornwall specimen of green bayldonite crystals richly covering quartz matrix from the less well-known Wheal Carpenter Mine. Wheal Carpenter opened in 1792, with sporadic and limited production continuing until 1855. Very highly representative material for the species and locality. Ex. John Ydren Collection.
9.1 x 7.0 x 3.8 cm. A VERY RICH and showy specimen of gold microcrystals on drusy quartz-covered matrix on this EXCELLENT specimen from historic Rosia Montana, Romania. Some gold crystals are golden bright, while other are a rich, mellow yellow. A nice contrast for a mine that was worked by the Romans. Ex. Chris Korpi Collection.
6.6 x 6.1 x 2.9 cm. An OLD-TIME and SUPERB Colorado specimen from the famous Calumet Mine! One of the very sharp, pseudo-hexagonal, water-clear quartz crystals is included with byssolite on this classic and aesthetic beauty. This is a CLASSIC, outstanding and pristine specimen from the Richard Hauck Quartz Collection. Comes with an OLD George English label dated August 17, 1889! George English was a prominent worldwide dealer and mineralogist, who lived from 1864-1944. Ex. Richard Hauck Quartz Collection.
5.2 x 5.2 x 3.0 cm. An old-time and showy specimen of lustrous, stepped, gunmetal-gray wolframite crystals attractively set amidst quartz on a massive wolframite matrix from a classic Czech locality - Schlaggenwald. Fine old material from the George Elling Collection.
6.8 x 6.3 x 1.0 cm. A SUPERB FLOATER, doubly terminated, Japan-law twin quartz crystal from Madagascar. This glassy, flattened, textbook example is transparent to translucent and has showy crenellated to beveled terminations. Very nearly pristine, with only trivial edge wear on one termination. DT Japan-law twin quartz is RARE. Very seldom available in this quality from this locality or ANY worldwide locality, for that matter. Ex. Rolf Wein Collection, a noted Alpine collector, and purchased in 1975!
10.2 x 4.3 x 4.0 cm. A sharp, excellent and showy CABINET quartz crystal included with 3 minerals and very attractively complimented by a 1.7 cm chalcocite crystal from the famous Messina Mine of South Africa. The lustrous and translucent, pseudo-hexagonal quartz is included with native copper, epidote and chlorite. The crystal is complete all-around and is partially coated. The back of the termination is cleaved and there is a bruise at the base of the termination on the display side, but overall, they are not detracting. This remains a RARE, HIGHLY UNUSUAL and excellent quartz crystal with multiple mineral inclusions and an uncommon and very showy sidecar crystal. Comes with a California dealer "Burminco" label. Ex. Richard Hauck Quartz Collection.
3.3 x 1.7 x 1.6 cm. An EXCEPTIONAL and pristine, doubly terminated quartz crystal included with hematite and having a fabulous, zoned phantom from the Orange River of Namibia. This is a real cutie. The phantom is striking and the sidecar crystals really add pizzazz to this super toenail from the dealer stock of Charlie Key.
7.1 x 3.4 x 3.1 cm. Little gemmy orange-red spessartines speckle the surface of one quartz crystal that has wrapped itself around another, both of them terminated - the "outer" one forming multiple terminations around the periphery of the "inner" one.
3.7 x 2.1 x 1.4 cm. You have seen many examples of spessartine on smoky quartz from Tongbei, but this one is really unique, in that the quartz got an opaque white mineral coating before the spessartines grew, giving it a chalky look and creating a really different take on this now familiar combo.
4.9 x 3.6 x 3.4 cm. Brandberg amethysts are famous for being water-clear with internal purple "blushes" as exemplified by this beautiful crystal, ex. Charlie Key collection. Tiny ding at the tip and one small natural contact on a face. There is an enhydro in this crystal - a pocket filled with trapped water, with a bubble that clearly moves back and forth inside it! You can see it move with the naked eye, but use a loupe if you cannot find it at first.
5.2 x 2.4 x 2.4 cm. A gemmy, glassy quartz crystal is completely shot through with glittering, golden acicular crystals of rutile.
4.9 x 3.3 x 1.4 cm. Goethite (basically, rust) can take on all sorts of forms. Here, it lines a cavity deep in the interior of a vug, underneath a layer of clear overgrowth that gives this fire agate its internal form! This is rare and precious material, sometimes used by very skilled jewelers. This is so pretty, though, it should remain a mineral specimen but you can see what a beautiful carving can be made to show off these bizarre inclusions. This is an intense and beautiful piece in person! It is so clear and strangely lightweight I mistook this for opal myself, as it was initially labeled here and is sometimes labeled by dealers. But it is technically a form of quartz var. agate, with goethite giving it the iridescence from underneath.
6.7 x 4.5 x 3.6 cm. The galenas on this Eastern European specimen have taken on all sorts of interesting variations on the basic cubic form, making it fascinating from a crystallographic standpoint. Quartz crystals stick up here and there amongst the galenas, and there is a bit of accenting golden chalcopyrite as well.
