This piece has to be one of the most aesthetic golds I have ever seen for sale from the old deposits here. It feaures an arborescent cluster of thick gold crystals leaping off contrasting TERMINATED quartz matrix. The gold is sturdy itself, and strongly embedded in the quartz as well. This incredibly aesthetic specimen has a long history! It was in the collection of the Austrian Museum of Vienna, until traded out and sold to collector Al Partee in the 1980s. When Al sold his his best miniature competition pieces, it went from him through Steve Neely to Irv Brown's miniature collection. I got it from Irv sometime in the late 1990s and traded it to Cal Graeber. Cal sold it to Mark when Mark was a curator up in Canada. Mark moved to Houston a couple of years ago. Mark brought it to lunch here in Dallas in July, and voila, its back with me again! I recognized it immediately. And, as a bonus, its now on the front cover of an important book on the mineralogy of Transylvania and these historic deposits. 4.3 x 2.7 x 1.3 cm
A killer miniature from this hard-to-get locale! Great Red Ledge specimens are scarce now. They used to come to market up until the 1980s or so. Some say they have the best lustre of any US gold specimens, and this one certainly illustrates the point in person. This one features both crystals and leaves, arranged elegantly around a core of quartz . It is of superior quality. 4.9 x 2.8 x 1.4 cm
This pretty combo specimen is from a single-pocket find of last year that we got most of, and certainly the best, specimens from. A pretty salmon-pink stilibite bowtie on a translucent stalactite of dove-grey quartz. 5.5 x 4.1 x 3.4 cm
These specimens were one of the few “new sensations” at the Tucson Show last year , especially as new finds were so scarce this year in general. We EXPECTED to see more at Denver but there were none to be had except for this small parcel which the collector had saved for us, based on a commitment we made right after Tucson when they flew off the shelves. THESE ARE THE ONLY SPECIMENS WE HAVE SEEN SINCE TUCSON! HE HAD NOT FOUND ANOTHER LARGE POCKET SINCE! At any rate, here is another shot to get one if you did not the first time around! This quartz crystal has purple-blue, sharp fluorite crystals included inside. The fluorites grew on the face of the quartz crystal at some point during its development in the pocket, and were later engulfed as the quartz continued its growth. The quartz crystal is more “silky” than lustrous in appearance. Crystal-in-crystal inclusions of this sort are of course quite exceptional, and are more often a one-off “oddity” than an entire pocket. 7.6 x 1.5 x 1.4 cm
Yes, this truly is as gorgeous as it looks! Transparent, sparkling quartz over turquoise-blue balls of chrysocolla, with contrasting dove-grey sparkling quartz - WOW!! 7.0 x 5.6 x 3.0 cm
Look at the fabulous articulation of the crystals on this old Michigan copper specimen! Their fine form is further emphasized by the presence of contrasting calcite, which serves as a backdrop for the crystals. The specimen shows a beautiful "antique" patina as well. Phoenix mine was active in the late 1800s 5.9 x 3.6 x 3.6 cm
This is a gorgeous specimen of Brazilian smoky quartz of the type commonly called "elestial" - and this one is really exceptional. The four intergrown smokies, of the "Herkimer" form, have grown on an extended crystal. They are gemmy with dark edges, almost jewel-like - the overall form of the specimen is just SO aethetic! 5.8 x 3.0 x 1.8 cm
11.8 x 8.3 x 6.4 cm. For sheer brilliance and brightness, this specimen hosts the best quartz I have yet seen for the locality. These gemmy, clear quartz crystals are of imposing quality, and rise from contrasting matrix of bladed hematite rosettes. All major crystals are pristine and free of damage, the only imperfect quartzes being those small ones lining the front and lower periphery.
This is a fine specimen from a stash we put away of a find about a year and a half ago in China of lustrous, bottle-green crystals of epidote on and amongst quartz crystals! This is really pretty material, and was unlike anything that had been seen before up to this find. This one has a really nice balance of quartz and epidotes! 18.8 x 10.1 x 8.5 cm
These new smokies from a gold mine in Bolivia are just world-class, are they not? These actually have wonderful dark smoky phantoms inside, and have a wonderful silkiness and sharpness about them. This one can be easily trimmed to a small cab if you prefer. 14.0 x 5.6 x 5.2 cm
A fine Eastern European combo specimen, featuring lustrous, super-sharp silvery crystals of galena to 1.5 cm accented by GEMMY quartz crystals. Very attractive! 7.7 x 5.1 x 4.1 cm
This is not a common Pakistani faden quartz but a BRAZILIAN one, showing a very clear faden line running across the middle of the gemmy, tabular quartz crystal. 4.1 x 3.1 x 0.7 cm
A large and impressive Eastern European specimen of translucent calcite crystals with a later generation of cream-colored microcrystals on them, selectively deposited only on certain faces, providing a contrast between opaque creamy and translucent light pink faces. 12.2 x 9.9 x 6.6 cm
An EXCEPTIONALLY RICH and RARE specimen of crystallized silver in granular quartz from the Atacama Region of Chile. This piece has both silver crystals and wires. This fine, old-timer comes with three labels. Rich and heavy for the size at 122 grams (4 ounces so almost solid silver here)! Ex Edna Doughty and Richard Hauck Collections. 6.3 x 4.1 x 2.5 cm
A BEAUTIFUL and SHOWY specimen of three, light brick-red fluorite balls to 8 mm in a vug lined with translucent, gray quartz crystals, These Indian fluorites are considered to be the finest fluorite balls in the world and the red balls are the most desireable. 3.7 x 2.8 x 1.7 cm
