Zircon- classic Colorado find
North Cheyenne Canyon, El Paso County
3.4 x 2.6 x 2 CM (miniature)
new june 17
A very sharp group of Zircon crystals with a great history. Collected in Cheyenne Canyon in 1945 by the late Warren Johansson in the last weeks before he was drafted. While awaiting his call up, Warren went on a series of legendary bucket list mineral hunting trips. He had been clued in by Clarence Coil that, long ago, some Zircons had been found in that area but the locale was lost. Warren located this spot and dug several nice pieces, some of the best ever found. This specimen was one of Warrens favorites and was pictured for his memoir. Warren passed in 2015
still active collecting in his 90s. This specimen is a fine Colorado classic from a great field collector.
A perfect complex twin of Cerussite with the zoned yellow color of the Chromian variety from Daoping. There are also several pink zones that make a nice color contrast. Fine Cerussites at this locale were always very rare and often overshadowed by the great finds of Pyromorphites and Plumbogummites. However the good ones like this are impressive. This would be a fine Cerussite from any locale and is in excellent condition, displayable on all sides, a true floater and with well above average luster. No naked eye visible damage at all, with 20X magnification I find one very small bruise, which is incredible for the delicate and sensitive mineral. This shows well the classic sixling twinning and overall reticulation. Fine form, color and condition.
A killer Potosi Bournonite with large, perfect crystals showing classic form. Complete all around, a perfect floater with no matrix, just big metallic Bournonites in fine condition. The largest crystal is a sizable 3.8 CM and all the crystals have a gleaming gunmetal luster. This is from the remarkable find in 2007-8 which had the very best Bournonites ever seen from Bolivia and some of the best ever found on the planet. This is very much a top percentile specimen from that discovery, a true top shelf piece.
Looking like partially melted ice cubes these are ultra clear habit Fluorites found at Dalngorsk more the 15 years ago. In excellent condition the Fluorites up to 2 CM are nicely contrasted with the matrix. It is difficult to photograph the gem clear perfection, the matrix is perfectly seen right through the crystals. Some very clear Fluorites still come out of this locale, but none are as clear as those from this older find, now a modern classic discovery. Super glasslike luster with no signs of frosting on the faces, even better in person.
Mimetite w. Arsentsumebite
Otavi-Bergland district, Oshikoto,
5.2 x 3.8 x 2.7 CM (small cabinet/large miniature)

Sprays of yellow radiating Mimetites up to 3 CM long on contrasting nmatrix in an esthetic array. This is a complex specimen with several display angles and a vug with Mimetites partly coated with micro Arsentumebites. In good condition overall, some micro damage can be found with magnification but still displays very well. A really nice specimen of accicular Tsumeb Mimetite.
Bournonite on Quartz
Yaogangxian Tungsten Mine, Yizhang County
8.8 x 4 x 3.2 CM (cabinet)
new june 17
A lustrous Bournonite is perched on one end of a doubly-terminated Quartz crystal from Yaogangxian. Remarkably, the entire specimen is fully crystallized and complete on all sides, it is a floater. A modern classic specimen- vintage 2004, the great era of Yaogangxian production. The Bournonite has well defined crystal faces on the front side, however the back side is less distinct, more complex, yet still perfect and undamaged.
From the original Karlsbad, this is a perfect Carlsbad twin of Orthoclase. The twin is a complete floater 360 degrees without comtact. There is a second twin perched in the center of the specimen, making this a twin-twin to coin a phrase. This habit got its name from early finds at Karlsbad and this is a textbook perfect example from an old Czech collection.
Deep purple color Flourite cubes in a chain arrangement. From the recent find of stacked or stalactitic Fluorites which had originally formed over Stibnite crystals that no longer present. Some edges have an epitaxial coating of Barite that makes a nice contrast. In fine condition and very esthetic. This was a very small find and few had this intense color.
