6.9 x 5.8 x 4.8 cm. An uncommon and beautiful combination specimen from the Tsumeb Mine. Sharp, euhedral quartz crystals are relatively rare from this historic mine, but this excellent piece is covered with a forest of glassy, translucent quartz crystals with a pretty, pink, oxide tint. A 9 mm, euhedral galena crystal is perched on one corner of the specimen and is a very nice contrasting accent. Scattered about on the quartz crystals are tiny, 1-2 mm, light brown wulfenites. Wulfenite on quartz is rare from Tsumeb. Ex. Rob Smith Collection, a noted Tsumeb specialist.
4.0 x 3.4 x 1.7 cm. From the great find of 2004. This specimen is a very attractive, very rare, fine, crystallized specimen of Potosiite consisting of several, extremely rare, highly lustrous, heavily striated, tabular blades (some are twinned) of measuring up to 5 mm sitting atop crystallized and the equally rare triclinic lead, tin, iron, antimony sulfosalt Franckeite with minor crystals of Galena. The crystals of Potosiite on this specimen are exceptionally large. Before these new specimens were discovered, some of the largest known crystals of Potosiite were massive, un-crystallized, granules less than 1 mm in most cases. This find completely redefined Potosiite.
12.2 x 6.2 x 4.8 cm. Galena with minor sphalerite and quartz from the Krushov Dol Mine in Madan. The galena has the highly prized "melted look". Excellent example from this now classic locale.
5.7 x 5.5 x 4.5 cm. An outstanding, brilliant metallic-gray galena cube nicely accented with marcasite and dolomite from the West Fork Mine of Missouri. Complete-all-around, this textbook cube is nearly pristine. There is even a 1.2 cm, amber calcite scalenohedron embedded on one side. The lustre is superlative. Ex. Wes Parker Collection.
8.4 x 5.4 x 3.2 cm. A superb and aesthetic cluster of splendent, steel-gray galena cubes to 1.3 beautifully accented with needle quartz, sphalerite and brass-yellow pyrite cubes from the famous mines at Madan, Bulgaria. Classic material from the Ed David Collection.
6.4 x 6.0 x 5.2 cm. An unusual specimen of fluorite, as this habit is rare for the locale. These robust, translucent, slightly pastel pinkish crystals are to 2.75 cm across. The fluorites are perched on a curving bit of quartz cavity that serves as host for a 2 cm galena crystal underneath. The galena is partially altered to anglesite, as are many from this locality. Interesting combination piece, overall. Ex. Harold Urish Collection.
9.4 x 6.1 x 4.3 cm. Good galenas are actually not very common from Elmwood. And this is a large, hefty, complete-all-around cluster of crystals attached en echelon to one another. It is complete-all-around, and in person actually quite a dramatic piece. Weighs in at about a pound. Ex. Harold Urish Collection.
5.6 x 5.0 x 3.2 cm. A single sharp, transparent, 3 x 2.8 x 2 cm fluorite crystal sits starkly in the middle of this crystallized, lustrous galena matrix, with a little accent of drusy quartz on the right side. Note it is so clear you can look right through it to the galena underneath. A fine miniature, with stark and classic cuboctahedral crystallography.
10.5 x 9.3 x 7.3 cm. Seven transparent, gemmy, undamaged cuboctahedral crystals to 3 cm in size perch like mountain climbers upon this mound of crystallized galena (actually a carpet of galena over a mound of underlying sphalerite). The contrast is striking. The association with galena is classic for Naica, for old material. For this new find, it seems rather unusual as most of the associations are with sphalerite. Also, the frozen waterfall of sparkling crystallized quartz running down the center of the piece provides a nice accent and some sparkle...and is itself unusual in the occurrence.
5.9 x 4.8 x 3.7 cm. A beautiful, pristine cluster of large cuboctahedral crystals perched on a galena matrix. They are gemmy and transparent, and complete-all-around except for a small contact in back where you can see some very pretty pyrite inclusions. Classic Naica crystallization.
5.9 x 5.8 x 3.7 cm. A striking specimen of intergrown, splendent, steel-gray, spinel-twinned galena crystals from a 2006 find at the well-known Krushev dol Mine of Bulgaria. This outstanding sulfide piece is composed solidly, front and back of spinel-twins, except for the 1.8 cm cube on the lower left. Complete-all-around and pristine, Looks like an M.C. Escher print. Ex. Brent Lockhart Collection.
8.6 x 6.2 x 5.5 cm. A showy cluster of totally gemmy, bi-colored, light sea-green and colorless, cuboctahedral fluorite crystals is perched atop galena and fluorite matrix. The crowning crystal is 1.7 cm and is beautifully included with a few pyrite crystals. The cuboctahedral crystal corners and edges are lightly frosted. From the older finds at Naica. The two primary capping crystals are pristine. Highly representative of the species and find.

6.5 x 6.0 x 4.0 cm. Although it does not look like much to the worldwide collector, this is actually a pretty good combination, locality piece for this mine. The johannsenite is the small brownish crystalline material forming the blanket in which are set sharp sphalerites, and matte galena. From the well-known Tucson collection of 40-year collector, Harold Urish.
This wonderful tri-state piece, mined in 1993, is interesting on BOTH sides. On one, it consists of pretty, transparent nailhead calcites, with galena and pyrite crystals adding an accent. On the backside are pseudomorphs of pyrite after anhydrite crystals - having completely replaced the anhydrites while retaining their platy form. 10.2 x 5.6 x 4.4 cm
5 x 3.5 x 2.1 cm. Mined in the 1830’s, this old-time specimen has quite a pedigree. The specimen consists of a pair of translucent 1.3 cm half-cyclic twins with excellent luster and good honey-brown color sitting on partially crystallized Galena. Both minerals are contacted or broken along the back, but that is not visible at all from the presentation side. This is an excellent specimen. Ex. Archduke Stefan of Saxony Collection, via Martin Ehrmann from the Museum of Bern to Richard Kosnar in the 1960s. Ex. Martin Lewadny Collection.
