HOLD Galenobismutite on Quartz
stock #HOLD AX-15-145
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
6.4 x 5 x 3.9 CM (small cabinet/ large miniature)
New Year 22
A very fine rarity from Yaoganxian, this is a rich, significant and esthetic Galenobismutite. It is the most attractive specimen of the specie that I have seen. Ex Shields Flynn collection, obtained from Bert Ottens some years ago who confirmed the specie, this is superb from this famous classic location. This visually looks much like a fine Boulangerite and would be an excellent specimen of that but the analysis shows this to be much more rare. It seems that there may be other specimens labeled as Boulangerite that are Galenobismutite. The matrix is a cluster of clear Quartz crystals showing two generations. The metallic needle crystals are in large masses on several faces of the specimen and are also included inside the largest, earlier Quartz prisms. In excellent condition. Mindat lists Galenobismutite from Yaogangxian but there is not yet a single photo from there.
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
7.1 x 5.1 x 3..4 CM (cabinet)
New Year 22
Sharp, highly lustrous Azurite crystals in a cluster on a contrasting reddish matrix. An early find Azurite specimen at Milpillas that is rather different in habit from later material. In excellent condition, clean and with bright "electric" blue crystals that are up to 1.6 CM and translucent to transparent. This mine is certainly a modern classic locality, and is now closed. During the short working life of the mine it became the world's greatest source of fine Azurites. The many diverse styles, habits and forms continue to make Millpillas a highly collectible locality. This is both a pretty, choice piece and a rather different esthetic. Excellent value.
A perfect, sharp and transparent elongated cube of pale blue to colorless Fluorite. This is heavily encrusted with Dolomite and micro Fluorites, so much of the Fluorite is hidden. A classic New York USA locality this is a cute thumbnail that looks better in person and shows the Walworth matrix "wrapping" very well.
Clinochlore is not often seen as a display quality specie, it is usually a minor associate or coating of other minerals. Here the Clinochlore crystals are sizable, well-defined and lustrous. The prismatic and sheaf-like crystals are unlike the more normal flat micaceous forms. The dark green crystals contrast well with the transparent to translucent white Adularia. Some micro species are noted in spaces between large crystals, most noticeable are gemmy Xenotime-Y with a yellow to orange color. A few spots of bright red Rutile crystals are also seen with magnification. Ex. Eric Asselborn collection, (France), this is a superb older Alpine specimen and exceptional for the specie, locality and habit.
From a small and very unusual find, this is an unusual and esthetic combination piece. The powder blue spheres are perched on needle crystals of deep green Malachite for a very nice contrast. The blue balls are mostly in clusters but some are also well-isolated. No damage and displayable from any angle, this find was quickly exhausted, there has been no more found. A different and distinctive form for Shattuckite, this habit is unlike anything from any other locality.
Pyrite with Dolomite
Niccioleta Mine, Massa Maratima, Grosseto Province
9.6 x 9.5 x 4.2 CM (cabinet)
New Year 22
A fine and well-developed cluster of Pyrite crystals showing deep striations and bright luster. Ex John Marshall collection, this is a vintage piece from a locality we rarely see, but which was famed for fine Pyrite crystals and some other Sulphides (Stibnite etc). In excellent condition the Pyrites are in clusters and also in well-isolated crystals. This is a solid and stable piece there is no sign of any degeneration or oxidation.
One of the mineral world's great classic pseudomorphs are the Hexagonal Pyromorphite crystals from Kautenbach that are replaced by Galena. These are all very old, vintage specimen most having been collected more than 150 years ago. These are also usually quite expensive and not many are seen in thumbnail size. This is a much more affordable specimen than any we have ever seen offered. We must note this is small and not super perfect, there are some edge chips and rough spots but it does show the desirable form and habit of this venerable mine. A good opportunity to have a fair example of this classic for an unusually good price.
Bear Creek Canyon, Colorado Springs area
4.3 x 3.2 x 3.1 CM (miniature)
New Year 22
A nice, colorful Amazonite crystal collected by the late Dr. Warren Johansson in 1945 just prior to his induction in the US Army. He had treated himself to a solo mineral collecting tour of the US Western regions while awaiting being shipped out overseas. He wrote a nice memoir about that adventure some 65 years later. The color is a little richer than most seen from this locality, the condition is quite good, there are several clean contacts but there is no damage or bruising. A classic US specie from Colorado, with some extra provenance.
