207 Mineral Photos
I've been collecting minerals for about 40 years, specializing in small cabinet to cabinet sizes. I have focus interests in alpine and lead mineral suites, although I do not restrict my collection solely to these areas. Crystal form, completeness, and placement on the matrix are particularly important to me, along with the provenance of the specimen. I am currently a member of both the Houston Area Mineralogical Society (HAMS) and the Houston Gem and Mineral Society (HGMS). I'm not much of a photographer, so this gets left to the professionals!

J1W-4QKWulfenite : Pb(MoO4)

Red Cloud Mine, Silver District, Trigo Mts, La Paz Co., Arizona, USA

Dimensions: 13.5 cm x 8.3 cm x 6.2 cm

13.5 x 8.3 x 6.2 cm. An incredible stakeholder's specimen from the 1997 excavations with huge crystals that are ISOLATED on matrix and remarkably without any repairs. The large crystal is 1.25 inches, over 3 cm. Unarguably one of the top pieces of the find, chosen as his pick by Gene Meieran BEFORE the public sale of the material through Wayne Thompson (Gene had an early pick as a financier of the project): chosen for combination of crystal size and isolation of those crystals on matrix (as he prefers big crystals). Ex. Dr. Eugene Meieran Collection.

9CL-984Wulfenite : Pb(MoO4)

Red Cloud Mine, Silver District, Trigo Mts, La Paz Co., Arizona, USA

Dimensions: 10.4 cm x 10.1 cm x 4.8 cm

This is simply an aberration. I have never seen so much red cloud wulfenite crowded onto one rock before, and so this just GLOWS with intense color. The color is RED, not orange , but the juiciest red you could want form the mine (most modern wulfenite has a more orange-nuanced hue to it). There are several crystals to an INCH in size here, elegantly rising on the top of the specimen. There is no damage to the top and most dramatic row of crystals, although there is in the middle of the piece a contacted 3-cm crystal growing vertically and another large damaged crystal facing out a tthe viewer on edge (and so visually minimized in both cases); and some matrix contacts along the lower half where the crystals contacted the pocket wall. Still, given the overall juiciness and size significance of the specimen, it seems a shame to trim the bottom half off to miimize these contacts, since the top is so pristine and intact, and the size itself lends significance. I , rather, like the size and overall visual impact you get from such a large Red Cloud specimen. There could not be more than a few others ever on the market in this size range, with so much coverage to them. I am told it was perhaps collected from a freak pocket in the 1960s. It certainly was not recently fro meither of the 1990s mining projects here, and it could even be an old Ed Over specimen from the 1940s. Regardless, the locality is now DONE with and no more will be found. This will remain an impactful and important cabinet piece, I would think. 10.4 x 10.1 x 4.8 cm
