Hemimorphite (unusual form, old mystery locale)
stock #AC-375
Cuvella Mine
Nevada, United States
6.4 x 2.2 CM (cabinet)
price: $350


A very unusual, old specimen with a slender stalactitic form and mysterious provenance. The Schortmann's minerals label that comes with this specimen dates it to the early years of their world famous dealership, about 1940. At that time a $5.00 specimen was a very costly piece. This period was the beginning of their historic association with Ed Over and Arthur Montgomery. The locale listed is the Cuvella mine in Nevada, which is not a "known" location. Whats more, the form of this piece is not like any I have seen from any locale worldwide, much less Nevada. It is 360 degrees crystallized with a central hole, micros of Barite and zoned dark inclusions, it looks almost violet in some lighting. In excellent condition with no eye visible damage, an interesting and mysterious piece. The stock number is typical of pieces that they obtained from older institutional collections both in the US and in Europe, but the meaning of the code is lost. Whatever the locale this is a fine and interesting specimen!
Amethyst (classic Guerrero candlepin form)
stock #12.1-261
Amatitlan, Municipio de Zumpango del Rio
Guerrero, Mexico
11.6 x 3.6 CM (cabinet)
price: $1400


A very good, older specimen with the distinctive form that makes the Guerrero Amethyst world famous. From the "golden years" in the 1930's vintage mining, This is a single crystal with a few side crystals attached presenting the "fat belly" form with good (slightly better than average) color. The phantoms are also quite distinct and are more impressive in person reaching a deep grape purple color at the core. Some typical minor bruises are seen in the photos, and some side crystals have chipping, but these can be hidden by rotating the piece. I would rate this specimen as well above average for color, size and form but not a "super-top" piece (which in this size can be a 20-30K specimen!). A good value for a fine addition for any Mexican collection or quartz suite
Galena with Chalcopyrite
stock #13.1-230
Black Cloud Mine, Iowa Gulch, Leadville
Colorado, United States
4.4 x 3.5 CM (miniature)
price: $175


Classic older Colorado Galena with well formed, complex cube crystals and a good contrast with the golden Chalcopyrite. Ex Ernie Schlichter, this is in very good condition (no eye visible damages) and quite 3 dimensional, a nice miniature with good luster.
Rosasite on Malachite- "treelike"
stock #A-4-246
Mina Ojuela, Mapimi
Durango, Mexico
6.9 X3.9 CM (cabinet)
price: $600


A fine and esthetic "treelike" or cruller specimen of velvety Rosasite on and mixed with malachite. There are some small Calcites as well for a little extra sparkle. Mina Ojuela has produced the best Rosasite known, usually in finds often decades apart. This was from the last find in 2011, mostly low quality but with a few outstanding pieces. I selected this from a small group of the very best. While not large, it has great color, form and eye appeal that make it an affordable yet worthy addition for any collection.
Stibnite
stock #A7-531-698
Grosseto Province
Tuscany, Italy
5 x 4.6 CM (small cabinet/ large miniature)
price: $260


A nice Italian Stibnite from Grosseto, with a great gunmetal silver luster. Crystals up to 3 CM long are in sprays on a dark sulfide matrix. Our labels from previous collections do not list the mine but this is a very good match for the Pereta mine in Scansano. Mostly undamaged showing a variety of terminations, some minor damage is noted but not easily noticed. Ex Larry White collection 1960's vintage but likely collected long before then. This is much nicer in person
Apophyllite (New find!, Bi-colored, Celedonite included)
stock #Alec 21-032
Shirurampur
Maharashtra, India
6.4 x 5.1 CM (cabinet)
price: $280


At last, something really new, pretty and quite different from the Deccan Plateau of India! A very few of these were presented in the Fall Denver show, but the dealers who had them did not agree on the exact location and the prices were often very high. It was a short lived sensation as all were sold quickly. This example is above average quality, with crystals to 2.8 CM, bi-colored both a deep apple green and a brown to purple-red. Nice contrast with the matrix and in perfect condition too. The location listed by one dealer is Shiurampur and for now I will use that information pending a verification. A nice addition for any Zeolite or Indian mineral collection!
Apophyllite (New find! bi-colored with celedonite inclusions)
stock #A- 21-033
Shirurampur
Maharashtra, India
5.7 x 5.2 CM (cabinet)
price: $320


At last, something really new, pretty and quite different from the Deccan Plateau of India! A very few of these were presented in the Fall Denver show, but the dealers who had them did not agree on the exact location and the prices were often very high. It was a short lived sensation as all were sold quickly. This is a better than average example in perfect condition at a more reasonable price. For now the best location we have is Shirurampor, that will be verified soon I expect. An esthetic, dark piece with deep color and nice luster. The crystals are a dark apple green with red-purple zones that adds a lot of nice contrast. We do not usually list many Indian Zeolites unless it is something especially great, and this stuff counts!
Pyrite, Magnetite and Xenotime (Y)
stock #1092-JM-1578
Hudson, Middlesex County
Massachusetts, United States
10.9 x 8 CM (cabinet)
price: $425


A Massachusetts rarity, from the John Marshall collection from a one time find over 40 years ago, during the construction of I 495. Two large, complex pyrites to 4.4 CM are perched on a jumble of micro crystals mostly Magnetites with numerous Xenotime. The right side crystal is in perfect condition, the left shows an old stress crack that is partly rehealed. An exceptional example of this find, I have not seen any better ever. Displays well.
