6.9 x 8.4 x 5.4 cm. This is a really 3-dimensional, elegant cluster of splaying quartz crystals, decorated at their junctions with small pyrites, from a classic old locality.
6.8 x 4.8 x 4.5 cm. Another beautiful old 1800s-era combination piece, from Neudorf. This specimen has one with galena to 1.5 cm on matrix with brilliantly sparkling quartz and siderite.
16.2 x 13.7 x 11.6 cm. The Himalaya Mine did not produce many large quartzes of good quality, and was heavily disrupted geologically so large specimens are rare in any case. Usually large crystals are repaired and heavily damaged - this is not repaired and has only a little damage (mostly to the top-termination facing to the right, out of sight) This is what I like to call a "pocket piece" in that it really illustrates nicely how gem crystals form in the ground. There are 3 tourmalines hanging off the quartz. The gemmier crystal, showing classic Himalaya pink color, is 2 inches plus some extra stalk below the gem area. The second crystal, totally different, is another classic style from the mine. It shows bi-coloration and is doubly-terminated, snugly anchored into the quartz on one edge. It is also 2 inches long. A third, slightly shorter but fatter bi-colored crystal sits on the backside. The tourmalines are undamaged.
9.0 x 5.0 x 1.7 cm. A fine, old-time combination crust from Taquaral, Brazil. Gemmy, glassy, vivid pink, rose quartz crystals are edged by a frill of brown esophorite crystals. Many of the rose quartz crystals are doubly terminated. The backside is totally covered with eosphorite crystals.
3.7 x 2.3 x 1.3 cm. Lustrous anatase crystals to 7 mm are artfully embedded on and in an aesthetic, jackstraw cluster of water-clear quartz crystals from Hardangervidda, Norway. Ex. Dr. Gary Hansen, Smithsonian Institution and Geology Museum at the University of Oslo Collections.
13.0 x 12.8 x 7.0 cm. A sculptural, freeform cabinet combination specimen from the Richard Hauck quartz collection and the Deardorff Mine of the famous Southern Illinois Fluorite District. Lustrous, glassy, milky quartz comprises most of the piece. One side of the central stalk has purple fluorite cubes, while the other side has a scattering of lustrous, black sphalerite crystals.
5.7 x 5.3 x 5.0 cm. An aesthetic cluster of lustrous and glassy, hematite-included quartz crystals from recent finds at the Orange River of Namibia. Ex. Charlie Key Collection.
4.5 x 2.2 x 1.7 cm. A glassy, parallel-growth quartz crystal tower richly included with epidote and beautifully complimented by sidecar, quartz crystals from Balochistan, Pakistan.
16.9 x 2.7 x 2.2 cm. The sceptre part at the top stretches 6 cm from its termination to where it bevels down to the host crystal at the bottom. The crystal is slightly smoky in color, and the accompanying hand-written label mentions chlorite inclusions. This crystal is actually terminated on the bottom, too. Ex. Richard Hauck Collection.
10.4 x 6.2 x 5.5 cm. These sphalerites notable for deep, cherry-red gemminess. This crystal measures 1.6 cm. There are some smaller crystals scattered around on the quartz crystal-covered matrix as well.
3.3 x 2.9 x 2.9 cm. This is a floater cluster of intergrown, doubly-terminated amethyst crystals from Veracruz. Ex. Richard Hauck Collection.
8.4 x 7.9 x 6.4 cm. A large, glowing, translucent crystal of amethyst from old finds in North Carolina. This big crystal has really interesting and unusual skeletal growth that you can see through its translucent faces, and particularly around the termination. At the bottom, you can see that the whole thing is actually a sceptre, the cap having wrapped itself around an original crystal. Most of this bottom crystal is complete is well, with healed faces and subterminations on the bottom. Ex. Richard Hauck Collection.
5.4 x 3.4 x 1.3 cm. The faden line, so-called string, is very clear running from top to bottom; the quartz is quite transparent, so you can see the faden line perfectly; and, this is a complete and uncontacted floater, with glassy faces and razor-sharp edges. Ex. Richard Hauck Collection.
6.9 x 3.2 x 2.5 cm. This is a fine crystal of Alpine quartz, a doubly-terminated floater with dramatic multiple terminations at one end. It is glassy-clear and has superb luster. Ex. Wein Collection.
14.4 x 12.9 x 8.6 cm. This is a large, classic Alpine smoky cluster. The "main" crystal measures 11 cm, and features fine transparency and razor sharpness. Ex. Wein Collection.
