Big (up to 4.2 cm), sharp shining metallic silver crystals clustered on matrix. Esthetic with better than average presentation, this is excellent specimen of this cobalt arsenide. Without doubt the Bou Azzer area produced the very best of the specie, prior to these the best were German, rare, expensive and far less pretty. The display side of this is in excellent condition. It is contacted on the right side and has damage at the rear where it was removed, not seen in normal display. This locality still produces a few good pieces every few years but it will not last forever. These are future classics especially when they are this good.
A fine, fibrous crystallized primary malachite from the prolific mines of Katanga. Excellent color, satin sheen and luster, no damage. Malachite crystals over 3 CM abound. The recent finds of this material have been well appreciated, affordable and very attractive. Not all fine minerals are expensive!
Grossular (gem Garnet)
stock #11.1 -W63
Jeffrey Mine, Asbestos
7.4 x 6.9 CM (cabinet)
The type of incredible garnet that made the Jeffrey Mine famous. A sizable matrix specimen with dozens of sharp, gem clear crystals that reach 1.5 CM. Top color and glass-like luster. Most crystals are fully perfect with delicate striations but there is damage or contacting on some crystals with most chipping at the edges and backside. Despite that, the overall impact is outstanding, and the cost is far less than the astronomic prices that fully perfect pieces command.
A big, very showy old time rose quartz with rare large well formed crystals. For some reason rose quartz prisms are nearly always little more than druse sized, a centemeter is sizable for the specie. On this specimen several crystals reach over 2 cm, most are quite gemmy and have attractive color. To add to the eye appeal, there are some crystals that have an orangeish hue, this seems to be cased by the color of parts of the matrix coming through the gem clear prisms. There is chipping damage to crystals at the outer perifery and some other chipping can be seen with magnification, but none of this is at all distracting. The condition is fine especially for such a large specimen. There is a small sawn area on the back that could be used as a base if desired, it is not at all visible from display angles. Vintage early 60's I have not seen anything quite this fine for sale in a very long time. Far better in person!
The sort of fine Fluorite that the Shangbao Mine has become world famous for. From finds in 2006, this habit has been found occasionally since and several large examples are known (and have sold for very high sums). This is simply a very esthetic smaller fluorite (3.3 CM) perched on crystallized dolomite with a few quartz crystals. Excellent condition, the fluorite also has a color change in different lighting from purple to blue. A very desirable and unique habit, in a relatively affordable specimen.
From the high elevations of Mt Xuebaoding (better known for Scheelites and Cassiterites), this ice like fluorite shows the rare habit of octahedron with a cube face on the tip of each corner. The surface has the "melted" look the re-crystallization makes and has a pleasing esthetic. Ex Bert Ottens and Marty Zinn Collections, this type of Fluorite is no longer being found and is a great addition to any serious Fluorite suite.
There are thousands of fluorites from the great Yaoganxian Mine, but very few are of this calibre. Incredible quality for the size and perfection. A single 4 CM glass clear, undamaged zoned cube sits on a 3 dimensional matrix perfectly. Top quality esthetics far better in person! This stands out from the rest and while it is a bit more pricey than average specimens, this quality is almost impossible to find in China today. The only comparable specimen I saw recently at a show was well over twice this price!
Ex Yale University collection and JH Marshall. An exceptional old classic specimen! A big, showy, well crystallized and heavy specimen of these rare Silver Chloride/Iodide species. Broken hill has produced the very finest of these minerals and both species are well presented in crystals up to 4mm densely packed. A rich yellow to waxy green color, the specimen is sawn on the backside and shows the matrix as a pure translucent green Mass. The old Yale labels (included) call this Cerargyrite which was in use in the 1950s and earlier. Far better in person and price well below the tags we have seen on many lesser pieces.
