HOLD Szenicsite with Cuprian Powellite
stock #HOLD 0921-JM-3859
Jardinera #1 Mine, Inca de Oro, Chanaral Province
Atacama Region, Chile
6.9 x 5.7 x 4.8 CM (cabinet)
price: $1450


A superb cabinet specimen of this very rare Copper Molybdenite ex John Marshall Collection. Sharp and well defined platy crystals are arranged in a radiating flower-like fan on contrasting matrix with zones of Cuprian Powellite. Good specimens of this quality are practically impossible to find now unless an older collection is being sold off. The original locality had an area less than a square meter that held a few clusters and that was it. That was more than a quarter century ago, this is now recognized as perhaps the most beautiful new mineral found in decades. Aptly named for the discoverer, Terry Szenics, pieces of this quality were limited to a few flats and were sold very quickly. This piece is far better than average and has a very well articulated crystal spray that reaches 3 CM. Excellent deep green color (some were much more pale) and bright luster. Since the original find this mineral has only been found in one other locality (Arizona) as micro crystals mostly under 1 MM and poorly defined. This is certainly the best specimen we have had.
Silver - wires with Quartz
stock #AC-379
Cobalt, Gowganda region, Timiskaming District
Ontario, Canada
6.9 x 5.9 x 4.3 CM (cabinet)
price: $760


Silver wires with tiny Quartz crystals coating and encasing some of the Silver. From the prolific Cobalt area this specimen is fairly old, it was sold by the Schortmann Brothers in the early 1960 era. The Quartz undermagnification is a sparkling druze of doubly terminated crystals many of which have a Cumberland habit. Close exam of the matrix shows that there is a lot more silver unclosed under layers of Quartz. The exposed area of wires is a dense nest with a few slender hairs rising to about 3 CM long. A choice, delicate and esthetic piece which looks better the more it is examined.
Rhodochrosite- scalenohedral form crystals
stock #10.1-193
Uchucchacua Mine, Oyon Province
Lima Department, Peru
6.3 x 4.2 x 3.4 CM (cabinet)
price: $360


Sharp and gemmy red Rhodochrosite crystals on a contrasting matrix. The crystals are mostly formed as Scalenohedral but take a few other forms as well. Uchucchacua is one of the worlds best Rhodo localities for Scalenohedrons, but not as well known (or expensive) as South Africa. Several crystals are partly coated with a thin crust of what seems to be Calcite and makes a nice contrast.
Galena, Cerussite and Wulfenite -Classic
stock #16.1-704
Bleiberg District, Gailtaier Alpen and Karnische Alpen
Carinthia, Austria
7.5 x 6.8 x 6.3 CM (cabinet)
price: $480


From the type locality area for Wulfenite, this is a very choice, classic Lead secondary specimen. About a dozen distinct octahedrons of Galena are sparkling with hundreds of Cerussite crystals scattered on the faces. The spaces between the Galenas are full of orange to red Wulfenites in a blocky form. One of the great classic mineral localities, important since the early 14th century. In 1556 Agricola described the locality and methods in his famed "De re Metallica" . The mines closed for good in 1993, but left a great legacy of minerals and helped develop many methods in use today. This specimen is in remarkable condition, is far more attractive in person and a fine display quality Galena much better than most seen in collections from here.
Thompsonite -Ca
stock #18-AX-6-019
Aurangabad
Maharashtra, India
6.2 x 4.8 x 3.6 CM (cabinet)
price: $360


Sparkling pink balls of Thompsonite on a contrasting matrix- a very attractive specimen of this usually drab mineral. The outer surfaces of the balls are covered with tiny needle crystals that make the luster far more bright than most typical Thompsonite. This is from a small find about 6 years ago that was unlike any Thompsonite found before or since, and were perhaps the best specimens ever. We sold this piece some time ago it is now back and we are happy to have it. One edge of this piece has balls that show the inner structure along the side. The overall quality, color and condition is excellent and this is a super example of this more uncommon Zeolite. A colorful and attractive addition to any suite of Zeolites or Indian minerals.
faden Quartz with tabular form
stock #AX-25-040
Waziristan Ophiolite, North Waziristan
FATA Federally Administered Tribal Areas, Pakistan
7.3 x 3.8 x 1.4 CM (cabinet)
price: $360


A perfect stack of tabular Quartz, gem clear and undamaged with a very distinct faden (string). The faden is at a slight angle off the C axis and is also slightly tapered. The flattened Quartz alone would be a very nice specimen, sharp, clear and lustrous but the strong faden and the textbook form make this especially choice. There have been occasional finds of faden quartz in Waziristan, this example comes from one of the last large pockets in 2015. Prior to these finds such a perfect Quartz from other locales would have been a magazine cover (and costly). The Waziristan Quartz finds did produce a lot of quite good pieces and the market price is currently much more affordable. Well above average and better in person too.
Almandine on Schist
stock #16.1-699
Otz Valley, North Tyrol
Tyrol, Austria
8.7 x 6.3 x 4.9 CM (cabinet)
price: $340


A sharp 3.8 CM Garnet is nicely perched on a silver- green Schist from this classic old locality. The Garnet is in excellent condition, is well exposed (and absolutely not "glued on"!). This is an old specimen yet it has not been enhanced as was often done years ago with faces polished or even painted on to add color. This is fully natural and quite esthetic, with no damage or edge wear.
Smithsonite -"sky blue"
stock #10.1-284
Choix, Municipio de Choix
Sinaloa, Mexico
8.3 x 4.8 x 2.2 CM (cabinet)
price: $260


The Choix locality at one time produced a rainbow of various colored Smithsonite. The "sky blue" was one of the more rare colors, while the green blue was the most common. The area is no longer being worked and these have become more prized in the past few years, yet are still far less expensive than most other localities. This is a vibrant and deeply colored example with very nice texture and luster, it is in excellent condition as well. I recently saw a polished cabochon of this material that looked just like a fine gem Silica, the color in person is similar. This will add a rich color to any cabinet or suite of Smithsonite.
