An interesting specimen with unique aesthetics, in that the quartzes are coated on many of the side faces by some included orange mineral. The stark white terminations stand in contrast to the bodies of the quartz 12.5 x 9.5 x 6 cm
5.5 x 3.6 x 3.4 cm. An old-time combination specimen from a classic New Hampshire locality - Conway. Glassy, transparent, smoky quartz crystals to 2.8 cm are "protected" by a sharp microcline crystal. Classic and excellent material from the Richard Hauck Collection.
3.8 x 2.9 x 2.6 cm. A fine, 2.5 cm, "mushroom" tourmaline from Burma, with the characteristic "cap", in this case a gemmy pink color and typical black core. The tourmaline is perched on the side of a partially euhedral quartz crystal.
9.1 x 6.2 x 3.8 cm. Gemmy and lustrous, sparkling burnt orange spessartine garnets cover the feldspar matrix on this fine, 3-dimensional specimen from recent finds at Tongbei, China. The three smoky quartz crystals are a nice accent and you can see where the garnets have totally encrusted blocky feldspar crystals to 3.3 cm.
8.5 x 5.9 x 4.2 cm. A fine and aesthetic combination specimen from recent finds in the Madan District of Bulgaria. This upright piece consists of metallic-bright, spinel-twinned galena crystals to 2.6 cm nestled amongst a "forest" of water-clear quartz needles to 1.8 cm. An excellent, highly representative combination piece from the Krushev dol Mine.
5.4 x 3.9 x 3.9 cm. Spikes of water-clear quartz crystals to 1.8 cm attractively crown an upright cluster of highly lustrous, striated, jet-black sphalerite crystals on this combination specimen from recent finds at the Madan District of Bulgaria. It is nearly pristine, for all its 3-dimensionality. Highly representative of the species and locality.
5.9 x 4.0 x 2.4 cm. A fine amethyst in agate specimen from Poland and the Dave Stoudt Collection. The unusual, sliced and polished nodule has a beautiful core of vivid purple amethyst and is surrounded by banded agate. This is the first amethyst/agate I have seen from Poland and this locale. Dave purchased the piece directly from the collector, while living in Poland.
5.2 x 3.5 x 2.8 cm. A beautiful, two-sided, mounded amethyst specimen. Four glassy, translucent to transparent, purple crystals of amethyst to 3.3 cm in size stand upright on the matrix. The crystals really sparkle and are called "cactus quartz" for their form. The terminations are isolated, while the bodies have a prickly, "cactus" look with an overgrowth of smaller crystals. This is the true source for the amethystine quartz crystals (aka "cactus quartz" and "spirit quartz") erroneously marketed as being from the Magaliesberg Range.
14.5 x 7.9 x 2.9 cm. A large plates of sharp, translucent octahedrons with unique purple and green tones, in contrasting stark white quartz. The crystals on this curved, cabinet plate measure to 2.7 cm. All of the crystals on this fine plate are purple, except the one on the bottom left, which is purple and green.
7.4 x 3.2 x 2.8 cm. A fine, old-time Ouray quartz specimen from the Richard Hauck Collection. This compound crystal has elegant form, with sub-terminations garlanded all-around the central, pristine, water-clear crystal.
4.5 x 3.3 x 2.2 cm. A fine miniature specimen of quartz replacing wulfenite crystals on a matrix covered with sparkly botryoids of pastel-green to blue, drusy quartz from the Finch Mine of Arizona. The largest crystal is 1.2 cm, all are pristine and the pseudomorphs are nicely translucent. This is a rich specimen from this find. Ex. K.D. Smith Collection of Tempe, Arizona.
7.3 x 7 x 5.5 cm. A fine 2 x 1 cm crystal of primary Malachite nestled in a Dioptase/Quartz pocket along with a beautiful 1 cm Dioptase and several gemmy Quartz crystals. The luster on all the crystals is excellent. Primary malachite, that has formed on its own chemical bonds and not without subverting and replacing a previous fine azurite crystal, is rare in this magnitude. This is a very robust primary malachite crystal with unusually developed termination. Ex. Charlie Key Collection.
8 x 5 x 4.8 cm. A fine cluster of thirteen Amethyst crystals on a Quartz matrix. The Amethysts have very good luster, and grade from a light purple in the lower halves to a beautiful deep purple in the upper halves, the likes of which is normally seen in the amazing Uruguayan Amethysts. The largest of these Amethysts is a 3.5 cm doubly-terminated crystal lying parallel to the matrix. Ex. Charlie Key Collection.
6.3 x 4.7 x 4.3 cm. A cluster of gemmy reverse-scepter Quartz crystals from Orange River. The primary growth Quartz crystals are all white with a very fine secondary druse. All the scepters are gemmy and have a preferential Hematite coating - what certainly would have been the early stages of just incredible phantoms. The largest crystal stands 4 cm tall. Ex. Charlie Key Collection.
10.4 x 9 x 7 cm. A fine specimen of aesthetic and partially gemmy amethysts, alongside a smoky quartz. The smoky quartz is doubly-terminated and 4.2 cm long. The largest of the Amethysts is 4.7 cm, with classic color and habit for the location. Ex. Charlie Key Collection.
