10.1 x 8.3 x 2.8 cm. This piece, exchanged out of an old collection in the Paterson (New Jersey) museum, is unusual in that the two portions of the Japan Law twin are so asymmetric. The whole piece is a floater with no contact, though it has a little spot of damage on one edge, and also on the tip of the small 2 cm associated prismatic crystal. It is a very different style of twin, from Japan or anywhere! Ex. Richard Hauck Collection.
10.2 x 6.6 x 3.9 cm. A really elegant, castellated piece comprised of stair-step rose quartzes shooting up off clear or milky quartzes, all sprinkled with really sharp, elongated, translucent eosphorite crystals to almost 1 cm in size. It is not a killer rose quartz, perhaps, because the intensity is a little dark - but it IS a very , very good piece, quite impressive, and a fabulous example of this particular old find (associated with the eosphorite) from the late 1970s. Ex. Richard Hauck Collection.
5.5 x 3.5 x 3.0 cm. A superb, very symmetric amethyst sceptre from an unusual locale....just have not seen many amethyst from Brazil at all other than the typical small crystals in geodes, and this fine sceptre is really therefore a shock to me. It is complete save a single small bit of contact or damage on one back face only. Ex. Richard Hauck Collection.
6.7 x 6.6 x 4.2 cm. A sharp smoky quartz crystal with amethyst highlights from an antique old Russian locale, from the important collections of both William S. Vaux and his relation George Vaux. This specimen rises from a slender shard of matrix covered by small quartzes, and is very aesthetic in person! The accompanying label is in the hand of George Vaux, whose collection went to the Philadelphia Academy of Sciences , though this specimen was exchanged out long before the recent sale of that collection. Ex. George Vaux, Richard Hauck, William Vaux Collections.
7.1 x 3.6 x 3.2 cm. A really beautiful quartz rich with sparkling, metallic inclusions of paper-thin pyrrhotite crystals, from this classic locality which is a deep gold mine. Never seen another like it! Ex. Richard Hauck Collection.
6.2 x 5.6 x 4.6 cm. A brilliantly shimmering and rich rutilated quartz from a most unusual locality! Such pieces, so rich and colorful, are VERY rare for the Swiss alps. This crystal is complete and presents nicely from the display face, though rough on the back faces and broken on the bottom. Ex. Richard Hauck Collection.
7.6 x 5.7 x 4.6 cm. A strange duo where the quartz crystal continued interrupted growth, but that interruption let a permanent barrier set up between the two portions of the crystal and so instead of a phantom, we have a detached "cap" that sits upon the original matrix and earlier crystal growth. REALLY WEIRD things, these! I have seen these bizarre "Russian doll" quartzes before only from a few historic samples. Most are big and clunky. This one is actually, as far as they go, rather elegant and a good size for a collection. Comes with a New York State Museum label denoting its origin from the G.F. Kunz collection (early 1900s). Ex. Richard Hauck Collection.
8.0 x 4.8 x 2.6 cm. A gorgeous specimen with an antique Ward's Science Establishment label dating it to pre-WWI in the early 1900s. Ward's was an active buyer at the time, but an even older (unidentified, calligraphy) label glued to the back indicates this may date to the earliest days of copper camp mining in Arizona. However, the pedigree aside, it’s just an incredible specimen with eye appeal due to the startling contrast of the (8mm) primary malachite crystals to the blue quartz underneath. It was, in Hauck's collection, a stunning blue quartz representative...but it’s more than a mere quartz in my book!
9.3 x 5.7 x 3.9 cm. A striking, 3-dimensional specimen of quartz featuring 2 generations. The first is the quartz that forms the central rectangle, having replaced an original barite crystal with a solid plate of quartz through pseudomorphing the baryte. Later, another generation of quartz grew atop, spraying out in all directions. The overall result is super-elegant and flashy, and very unusual. It is amazing it has survived in such good condition (only one tiny missing crystal out of all!). Said to have been found by the legendary field collector Arthur Montgomery, according to Hauck. Ex. Arthur Montgomery, Richard Hauck Collections.
8.8 x 4.3 x 3.7 cm. A gorgeous and classic Cripple Creek amethyst specimen with an antique Ward's Science Establishment label dating it to pre-WWI in the early 1900s. The script is in Henry Ward's own hand! Complete all around 360 degrees; and nearly pristine save only a small kiss on the very tip (hard to see, anyhow). However, the pedigree aside, its just an incredible and aesthetic example of a classic old find we rarely see today, even in museums. So few good examples of these have been on the market! Ex. Richard Hauck Collection.
8.5 x 5.1 x 4.4 cm. A bizarre, organic-looking smoky quartz that was naturally etched in its pocket by solutions to produce this artistic-looking single crystal that is a complete floater all around, with brilliant reflections off its many micro-faces. MUCH better in person, and quite rare in form for the location. Ex. Richard Hauck Collection.
8.5 x 4.3 x 3.4 cm. This specimen is a lustrous, bright, pleasing color and is doubly-terminated with multiply-terraced faces extending out on each tip. It is complete on the display face but for one minor tip, and has contact on the left edge and backside, but presents as a complete floater from the front view. Ex. Clarence S. Bement, Richard Hauck, Smithsonian Institution Collections.
8.2 x 7.3 x 5.1 cm. An interesting old English piece, with quartz crystals soaring up from an (unusual) pyrite-rich matrix. Small "chalcpoyrites" which I believe to actually be tetrahedrite, are intermixed near the base of the quartz crystals and within them, on the matrix. Ex. Richard Hauck Collection.
11.7 x 6.2 x 4.5 cm. A stunning clear quartz cluster, no doubt a very old one , from Arkansas' classic quartz mines. It is complete all around and remarkably in very good condition. Exceptional clarity and quality even by modern standards. Ex. Richard Hauck Collection.
18.9 x 8.5 x 6.6 cm. A superb and unusually large floater, single crystal of smoky quartz, miraculously in excellent condition despite being over 100 years old! Interesting, and I have not seen this often on this form of quartz from here, there are small hematite crystals perched atop, like sprinkles on two faces. Ex. Clarence S. Bement, Richard Hauck, Smithsonian Institution Collections.
