Prehnite -very well crystallized
stock #18-AX-24-496
Jeffrey Mine, Asbestos
Quebec, Canada
3.6 x 2.8 x 2.1 CM (miniature)
price: $480


Unusually sharp and transparent crystals of Prehnite in an esthetic cluster. The crystals are in fine undamaged condition and this specimen has a lot of display impact. The Jeffrey mine is famed for its Garnets and Vesuvianite but the Prehnites found here were world class and of incredible variety. This is an excellent example showing the elongated blocky form with a delicate light green hue. Even though Prehnite is not a rare mineral and is found worldwide, good sharp crystals are rare and these from the Jeffrey are unique. Not found for some years, these are modern classics and no others from elsewhere have this look and habit.
SOLD Brucite -well crystalized, historic specimen
stock #SOLD 18-ax-35-93 (1481)
Wood's Mine (Woods Chrome Mine) Lee's Mills (Texas)
Pennsylvania, United States
8.2 x 4.6 x 2.4 CM (cabinet)
price: $575


From the famed Wallace Gould Levison collection, acquired by him in 1895, a very choice Pennslyvania Brucite. Levison obtained this from an even older collection so it is clearly a very early piece. Bladed crystals and rosettes of pale greenish Brucite contrast with the darker matrix. This specimen is fluorescent and Levison was an early experimenter with this, he invented and patented a system for studying FL responses in differing wavelengths. He notes this response on his handwritten label affixed to the piece. In fine condition this is a choice Texas, PA specimen even without the added historic importance. At one time these rare old Brucites were considered to be the finest in the world, but recent finds abroad have taken that title. Despite that these classic Brucites are distinctly different and are still prized in collections and far harder to obtain than the recent yellow Pakistani specimens.
Fluorite - gem clear
stock #18-AX-20-237
Penfiled Quarry, Penfield, Monroe County
New York, United States
3.2 x 2.3 x 2.3 CM (thumbnail)
price: $360


An ultra clear sharp and glassy Fluorite cube perched on Dolomite. Choice thumbnail or small miniature of a Penfield New York Fluorite, this was collected more than two decades ago. Flawless with no damage at all even under strong magnification. The matrix is clearly seen through the Fluorite, which I would describe as a clear colorless ice. In some light however a very slight hint of blue is seen. A modern USA classic, New York Fluorites are relatively rare, and are prized when perfect and esthetic.
Calcite - color zoned with phantoms
stock #7AE-144
San Antonio Mine, Santa Eulalia, Aquiles Serdan
Chihuahua, Mexico
10.8 x 7.9 x 3.7 CM (cabinet)
price: $360


A striking color zoned Calcite from the San Antonia Mine, Santa Eulalia. This was mined about 20 years ago, and shows two generations of Calcite with different habits. Brilliant red color and with bright luster, the red is most likely from Hematite. The display face is in excellent undamaged condition, the only damage is along the outer edges where it was removed but even that is minimal. A distinctive, colorful Mexican piece that is much more impressive in person.
Calcite -"Mushroom habit"
stock #7AE-470
Fengjiashan Mine (Daye Copper Mine), Edong District, Daye County, Huangs
Hubei, China
7 x 5.4 x 4.3 CM (cabinet)
price: $340


From a find in 2005 in Hubei, these mushroom like Calcites made big news then in the mineral world. We sold this example at that time and it is now back with us to be offered again. This is colored on some faces by inclusions of Hematite which adds a nice contrast. The display face is in fine condition with no visible damage, but there is a notable cleave on back of the left side that is seen from that side, and the bottom is broken at an angle so the base is also cleaved. Despite that cleave this is still an attractive displayable specimen that shows the form perfectly. The "stem" has a series of flat Calcite tabular crystal ridges that are more deeply colored red.
Vanadinite
stock #19.1-300
Mibladen Mine, Upper Moulouya lead district, Midelt, Khenifra Province
Draa-Tafilalet Region, Morocco
4 x 3.4 x 2.2 CM (miniature)
price: $320


Among all the nice Vanadinite that has come from Morocco, a few pieces do stand out as having a next level of color, form or general impact. This is an outstanding miniature with that intense red color, bright luster and sharp, free standing crystals. The overall composition is attractive from almost any angle, there is just a little matrix that adds nice contrast. With the past few years production of Moroccan Vanadinites it is easy to take these for granted, yet they are clearly superb and one of the best values in the mineral market. No damage.
Cobaltite -classic locale, fine single crystal
stock #16.1-148
Tunaberg, Nykoping
Sodermanland, Sweden
1.3 x 1.1 x 1 CM (thumbnail)
price: $390


A sharp, complete and perfect textbook form Cobaltite crystal from the classic locale of Tunaberg (Sweden). The worlds best Cobaltites have come from two localities in Sweden, Tunaberg and Hakansboda. This has a trace of Chalcopyrite on one face which is more typical of Tunaberg specimens. Well above average quality, the luster and form are impeccable.
Duftite on Quartz
stock #17.1-795
Black Pine Mine, Flint Creek Valley, John Long Mts., Granit Co.
Montana, United States
12.8 x 9.3 x 4.2 CM (cabinet)
price: $650


A large plate of Quartz crystals up to 2 CM in size are thickly coated with Duftite in olive-green spheres. An old specimen from the Black Pine Mine that is famed for the great Veszelyite finds there. I have not seen another specimen quite like this from any USA locality it looks like a dark botryoidal Tsumeb Duftite on a Montana Quartz. An unidentified coating of brighter yellow is also present and adds some contrast. it is a very significant and sizable Duftite specimen with a lot of character. In good condition overall there are a few tiny chips on some Quartz but most are perfect and undamaged. The Black Pine mine has a complex and wonderful mineral assemblage including many uncommon associates. This piece is significant for the locale is the best USA Duftite I know of. Ex Chris Amo collection.
