4.8 x 3.4 x 2.6 cm. A glassy, gem-like Herkimer Diamond quartz scepter very nicely accented with a shard of matrix and a smaller crystal from the famous deposits at Middleville, New York. The internal crazing really adds character to the complete-all-around "diamond" and the quartz stalk is also terminated, thus this is a doubly terminated specimen. Ex. Daniel Trinchillo Sr. Collection.
8.2 x 4.6 x 2.8 cm. A stunning, water-clear, sharply terminated quartz "obelisk" is beautifully accented with an interesting protruding wreath of sparkly, brass-yellow pyrite microcrystals over sphalerite from the Panasqueira Mine of Portugal. The quartz is complete-all-around, nearly pristine. Classic and superlative combination material from this famed locale.
8.6 x 5.8 x 5.1 cm. This is an aesthetic, wing-like cluster of lustrous, translucent, flattened, rose-red rhodochrosite rhombs nicely accented by fluorite, quartz and pyrite from recent finds at the Wudong Mine of China. The largest rhodochrosite is 4.2 cm and many of the faces are lightly frosted. The quality of Chinese rhodochrosite keeps getting better and this is an excellent example.
26.0 x 25.4 x 9.0 cm. A huge, dramatic, two-sided, large cabinet, Chinese plate covered with striking, yellow, iron-stained, water-clear quartz crystals on one side and much smaller, drusy quartz-covered quartz crystals on the other side. The quartz crystals reach about 5-6 cm. The yellow iron stain is not your typical red iron oxide stain and makes for a very showy large piece. Highly representative, very large material from an uncommon Chinese locality for quartz. Weighs 10.8 pounds or 4.9 kilograms.
12.8 x 10.0 x 6.1 cm. The famous quarries around Jalgaon continue to produce a stunning variety of specimens and this is certainly a prime example. A unique column of sparkly, gem-like, smoky and colorless, drusy quartz crystals rises above the floor of the very well-prepared cabinet vug and contacts the other side of the vesicle, as basalt is still attached to the tip of the column. A 1.0 cm, gem, amber calcite rhomb attached to the side of the column is a fine accent. Lustrous, colorless stilbite blades beautifully highlight the undulating floor of the vug covered with smoky, drusy quartz with colorless, drusy quartz on the larger crystals. This is an unusual and striking Jalgaon specimen. Ex. Saller Collection of Germany.
7.4 x 7.3 x 5.8 cm. A fine, mounded, combination specimen from recent finds in Argentina. Glassy, nearly transparent smoky quartz crystals are very attractively scattered amongst cream-colored microcline crystals. The interesting, perched smoky quartz atop the mound is 2.3 cm. Highly representative of the species and locale.
A VERY unusual Colorado combo specimen featuring light purple fluorite (!) - or more specifically, it appears to be clear with a purple core - in association with smoky points and well-formed euhedral microcline crystals. The fluorite will not give a Berbes fluorite any competition, to be sure, but it is from Colorado, for gosh sakes. 4.9 x 3.6 x 3.0 cm
6.3 x 3.1 x 2.4 cm. Lustrous, transparent, gemmy eosphorite crystals to 7mm liberally coat this elongated quartz shard. This is a very high quality specimen from famous finds of the 1980s, still the best quality if you like lustre and transparency in this species. Ex. Martin Zinn Collection.
6.1 x 5.9 x 1.1 cm. A very attractive combination specimen with sharp and gemmy eosphorite crystals, unusually well isolated on matrix, to 1 cm in size. This is highly unusual for the habit. The small green spheres were identified as kidwellite but are more probably the species zanazziite, though I have not X-rayed to be sure. Ex. Martin Zinn Collection.
2.5 x 2.0 x 1.3 cm. Perched on a matrix of drusy sugilite is a pristine, transparent quartz crystal measuring 2.25 cm in length. Included within the quartz crystal is sugilite, which is an incredibly beautiful, rich, lilac color.
6.5 x 5 x 4.2 cm. A superb example of rare natural citrine from Mexico, with rich, amber-colored, robust crystals in a stunning knob. This is a very rare and really good example from a small batch brought to market by Doug Wallace at one of Marty's Hotel shows in Tucson about 4 years ago. Ex. Martin Zinn Collection.
6.5 x 4.9 x 4.7 cm. An aesthetic and unusual specimen from recent finds in Namaqualand, South Africa. The glassy quartz crystals at the top of this piece have intensely purple interior phantoms, just in the termination portion of the quartz crystals. These crystals give the distinct impression of being scepters, but they are not.
5.4 x 5.0 x 3.3 cm. A beautiful, classic and old-time specimen from the famous Wheal Gorland of Cornwall. Numerous vugs are lined with very sparkly, dark forest-green, botryoidal olivenite microcrystals in the quartz-rich matrix. Primary production at Wheal Gorland was over by 1851. Seldom are Wheal Gorland olivenites of this richness and quality available and only from recycled, older collections. Ex. A.K. Borland and Wes Parker Collections.
3.8 x 3.7 x 2.8 cm. An interesting and older combination specimen from the Himalaya Mine and the Robert Whitmore Collection. A gemmy and lustrous, well-striated, multi-hued green tourmaline crystal is very aesthetically accompanied by an angled, doubly terminated quartz crystal and a lavender lepidolite book. The tourmaline is doubly terminated. This classic Himalaya piece dates to the 1950 or 1960s.
4.8 x 3.5 x 2.8 cm. Pearlescent, doubly terminated, salmon-pink stilbite blades are beautifully attached to a column of translucent, light gray, drusy quartz crystals on this very aesthetic specimen from recent finds at Poonah, India. The drusy quartz column has an interesting, thread-like core running the length of the interior. Complete-all-around and pristine. Ex. D. Trinchillo Sr. Collection.
