OKF-467 Quartz and Calcite Biggeden, Australia. Ex. Dr. Steve Chamberlain collection, prev. Lewis Beebe, 1976. Unusual locality! This 3.5 cm singly terminated quartz is frosted by tan colored micro quartz on exactly half (thankfully its back half) of the crystal. Attached are clear calcites which contrast the quartz nicely. The form variations, layout of the minerals and sharpness of the specimen all add to this pieces appeal. A small internal bruise can be seen on the largest of the calcites but is not distracting. This could be a magazine cover worthy specimen if properly photographed. 150$

OKF-073 Cerussite Brown’s Prospect, Rum Jungle, Alligator Rivers Region, Northern Territories, Australia. Ex. Dr. Steven Chamberlain collection. A fine reticulated cerussite twin with some minor basil and side contacts but very displayable. This classic material has become very difficult to obtain these past few decades in decent specimens.

A desirable piece at a reasonable price. 100$

OKF-074 Rhodonite North Mine, Broken Hill, New South Wales, Australia. Ex. Dr. Steven Chamberlain collection. Typical gemmy material with a high degree of internal fracturing.

OKD-550 Rhodonite on Galena Broken Hill, New South Wales, Australia. Ex. Nancy Collins Collection. A beautiful 2 cm crystal erupts vertically out of galena. The crystal has gemmy regions with a good deal of internal flaws. Although it may not appear gemmy, keep in mind that I never backlight my specimens like the competition loves to do. You will be pleased with its color and clarity. Double terminated with the basil termination being almost entirely buried in the galena. The upper termination is damage free, fully exposed, complex and interesting. Some faces are sharp and others morphed (or smoothed over) which is normal for these crystals. Prism faces are all very clean. 3.2 x 1.6 x 1.6 overall. Tiny rhodonite crystals climb up one side of the galena matrix. A top, competitive thumbnail specimen. Very rare to see these for sale and almost unheard of in this quality. Classic location, exceptionally well formed and a very rare and difficult to acquire specimen. 3,100$

OKD-144 Dravite Yinnietharra, Western Austrailia. Ex. Dr. Steve Chamberlain Collection. I’ve sold dozens of these over the years and this one is certainly the best miniature specimen I have had, or seen. One tiny ding of a few millimeters on a corner but otherwise a perfect crystal with just the right amount of mica matrix. Translucent, good luster, perfect symmetrical form. 3.5 cm crystal. Views from all sides equally well. Killer miniature. 55$

OKD-135 Quartz Mt. Jerusalem, near Murwillumbah, New South Wales, Australia. Ex. Dr. Steve Chamberlain Collection. 4.5 cm ball of quartz blades which looks more like a coral formation than a mineral specimen. Light bluish white color and a very unique form. Result of differential weathering of a fractured concretion which the fractures had been filled by quartz? Certainly very interesting just the same. No damage. 30$
