4.5 x 3.1 x 2.5 cm. This Swiss fluorite specimen is quite unusual. The lovely pink, moderately lustrous fluorite octahedrons are attractively perched on a lustrous, gemmy, tabular quartz crystal (itself transparent and sparkling underneath). The combination as a whole is striking and unusual, so you can see why it was long in the George Holloway Collection, a California collector and friend noted for his superb taste in miniatures and fluorites in particular. The locality, please note, is not the (relatively more) common locality for pink fluorite of Chamonix in France. Rarer are these pinks from Switzerland.
10.5 x 5.5 x 4.3 cm. A beautiful, cabinet combination specimen from recent finds at the Yaogangxian Mine of China. A striking "bouquet" of translucent, intergrown, light purple, stepped-growth face fluorite cubes is aesthetically perched on the side of a transparent to translucent quartz crystal. The termination of the quartz crystal is extremely interesting: three of the hexagonal faces above the fluorite are recessed, etched or are covered with tiny fluorites, while the back three faces are very glassy and two of the faces are included with green chlorite.
7.4 x 2.7 x 2.1 cm. A unique and very unusual quartz find now gone and done with, with specimens hard to get today after 3 years out on the market. A complete-all-around, lightly frosted, water-clear quartz crystal is included with crudely crystallized dark blue/purple fluorite. This showy piece is from a most unlikely for fluorite locality – Madagascar. Very nearly pristine, an excellent example from the find of perhaps 5 years ago now.
6.2 x 5.4 x 3.6 cm. This is an important old locality. Material from this famous erratic deposit goes back nearly 300 years in the literature. These were treasured by mineral collectors when all collectors in Europe were nobility or their associates, and considered one of the hallmarks of great collection. Here, a gemmy and lustrous, 2.6 cm, yellowish topaz crystal with a complex termination is elegantly set on a field of quartz needles on quartz-rich matrix from the famous Schneckenstein cliff of Saxony, Germany. It is a large piece, an aesthetic piece, and this is a very large crystal for this classic locale. It is nearly pristine. Smaller topaz crystals are a nice accent. Note how the large crystal sits up on the matrix, instead of being buried in matrix as so many from here are. Circa 1800 (assuming the "98" on the old label is dated 1798 by its similarity to others I have seen), and comes with two old labels.
9.0 x 8.0 x 3.1 cm. A dramatic and rare quartz specimen from Brazil and the Richard Hauck Quartz Collection. The glassy, translucent, flattened, "alligator" smoky quartz crystal "plates" have rare amethyst tips and the crystals are included with even rarer specular hematite flakes.
6.8 x 2.9 x 1.9 cm. Now very rare on the market, this is an excellent small cabinet cluster of a rare habit and color of red quartz found at Dal’negorsk in the late 1990s. There were very few of these fat, tapered crystals found. The color is phenomenal and unique. It is complete, although there is a white secondary coating atop portions. This is an unusually robust and well balanced specimen. To this day Ii have never gotten a good answer as to what causes this bizarre and unique coloration.
5.2 x 4.9 x 3.2 cm. Classic combination for the old locality. This specimen features curved, sparkly, rich pink rhodochrosite crystals to about 7mm, on glistening quartz matrix. Ex. Harold Urish Collection.
7.9 x 6.6 x 4.6 cm. A beautiful pocket of chrysocolla forming little rounded stalactites that have been covered by a thin layer of sparkling quartz druse. The quartz protects the softer chrysocolla underneath and also accentuates the color and richness of the piece - these are the most desired of the chrysocolla specimens from this classic old locality. This is an excellent piece for the overall form and size, and the top color intensity. Ex. Harold Urish Collection.
9.5 x 8.5 x 5.1 cm. Small, pale green fluorites perched amidst sparkling quartz, a locality piece of some interest as good fluorite is rare from Arizona. From the Oregon Mine. Ex. Harold Urish Collection.
6.2 x 5.2 x 3.5 cm. Butte rhodochrosites are true old US classics, mostly coming out over 40 years ago now. This is a great association piece with sparkling quartz contrasting against the pastel red rhodochrosite rhombohedra. Now scarce on the market. Ex. Harold Urish Collection.
13.2 x 8.7 x 4.8 cm. This unusual specimen is a quartz piece now, with the quartz crystals having grown upon a thin shell of quartz cast after another, now missing mineral species (presumably baryte). The box-like cast form is clear from the back of the specimen. On the front, it presents a very sparkly quartz face arranged vertically for display. Rare locality material. Ex. Harold Urish Collection.
6.7 x 3.2 x 2.2 cm. A really gemmy, bright, transparent quartz crystal from this famous district. In person, it has a color somewhere between quartz and amethyst, a pale lavender hue that is subtly attractive, often referred to as amethystine. Note the internal phantom, inside. Ex. Harold Urish Collection.
7.2 x 6.1 x 5.0 cm. This is rare material. These crystals of wulfenite have been replaced by drusy quartz in a rare pseudomorph, that I can recall seeing from very few localities. This was collected in the early 1990s and created a stir at the Tucson show in those years. Now, almost impossible to find except in old collections as they recycle. Ex. Harold Urish Collection.
5.0 x 4.1 x 3..3 cm. A sparkling miniature of chrysocolla stalactites that has been covered by a thin layer of sparkling quartz druse. The quartz protects the softer chrysocolla underneath and also accentuates the color and richness of the piece - these are the most desired of the chrysocolla specimens from this classic old locality and valued quite highly. Pieces like this often get cut up to provide lapidary material for fancy southwest jewelry. This is an excellent piece for the overall form and size, and the top color intensity. Although some stalks are broken, the central stalactite is intact and the overall color and sparkle of the piece make it a very fine specimen. Ex. Harold Urish Collection.
4.7 x 3.3 x 2.3 cm. An unusual fluorite locality. Here we have sharp quartz growing out of the fluorite - usually it’s the other way around. Ex. Harold Urish Collection.
