OKI-449 Pyrite French Creek Mines, St. Peter, Chester County, PA. Ex. Dr. Steve Chamberlain Collection. Circ. 1976. A showy example composed of what I would describe as a single complex crystal measuring 2.5 x 2.4 x 2 cm. The specimen shows distorted form which gives the piece a saddle shaped appearance of a dolomite crystal. This is not an uncommon habit for this local but quite unusual for pyrites, in general. There is only a minor area of attachment to magnetite on the lower section of the backside, so the specimen shows wonderfully when viewed from almost any direction. Very fine, no pyrite disease issues with good specimens like this from this classic east coast locality. Zero damage. 175$

OKI-450 Rutile Rist Mine, Hiddenite, Alexander Co., North Carolina. Ex. Dr. Steve Chamberlain Collection. Prev. Dr. George Robinson. Circ. 1973. An exceptionally fine rutile crystal with impeccable form. This 2.1 x 1.1 x .8 cm beauty is a single primary crystal with a tiny amount of a second crystal (showing the twinning that is present ) near the base. This small crystal has a chip, but I consider this a very minor issue given the high quality of the large primary crystal. The color is a rich metallic red and there is minor translucence. A fine specimen from a very famous mine. 390$

OKI-451 Galena in Calcite with minor Epidote Lane Quarry, Westfield, Massachusetts. Ex. Dr. Steve Chamberlain Collection. Circ. 1976. A nice metallic silver colored cube partially embedded in calcite. It is .8 cm on edge and bordered by some tiny, deep green epidote crystals. Specimen measures 3 x 3 x 2 cm and is a rare species for the quarry. Partially cavernous crystal. No damage. 35$

OKI-452 Rutile Rist Mine, Hiddenite, Alexander Co., North Carolina. Ex. Dr. Steve Chamberlain Collection. Circ. 1979. An exceptionally fine, acicular rutile crystal with impeccable form. Double terminated with one end being hollow (etched) and the other a basal pinnicoid. 4.3 cm long but due to how thin it is you can actually fit it in a TN perky box. The color is a rich metallic red and there is minor translucence. Another fine specimen from a very famous mine. 150$

OKI-454 Pyrite on Sphalerite French Creek Mines, St. Peter, Chester County, PA. Ex. Dr. Steve Chamberlain Collection. Circ. 1979. A showy example composed of what I would describe as a plate of crystals measuring 3.4 x 2.8 x 1.5 cm. The specimen shows wonderfully when viewed from any direction. Minor attachment of a light green mineral which is possibly fluorite. The crystals show a distorted form which gives them a saddle shaped appearance like that of a dolomite crystal. Very fine, no pyrite disease issues with good specimens like this from this classic east coast locality. No damage. 50$

OKI-456 Vesuvianite Eden Mills, Vermont. Ex. Dr. Steve Chamberlain Collection. Circ. 1979. A stocky 2.2 cm crystal with a single termination. Gemmy in areas, deep rich green color, glassy and well formed. Tiny rub, damage (difficult to see), to tip but still an important specimen. I’ve killed the price on what would have been a very expensive piece, less the very minor damage. 75$

OKI-457 Chalcocite Bristol Copper Mine, Bristol, Hartford Co., Connecticut. Ex. Dr. Steve Chamberlain Collection, prev. Dick Kelley and University of Rochester Collections. This is certainly a classic east coast locality with no rivals for this rare species except those from Wisconsin. Specimens from this locale are one of the true cornerstones of any respectable east coast site. This twinned TN specimen measures 2.1 x 1.5 x 1.1 cm thick. It is crystallized on all sides with only two small areas of edge contact (one on each each of piece). This piece has a fantastic classic look due to its even, steel gray patina. Sharply crystallized in all areas with the twinning being obvious. Some of the smaller crystals in this somewhat parallel growth aggregate are double terminated. Great views from all sides. More three dimensional than it may appear in the images. Excellent provenance. These things have become as rare as “hens teeth” and are mineralogically important (ref. Rocks and Minerals, 11: 37 and the Mineralogical Record, 32, 433). An exceptionally fine, rare and desirable specimen for the discriminating thumbnail collector. 1,900$

OKI-460 Elbaite RESERVED Lord Hill Mine, Stoneham, Oxford Co., Maine. Ex. Dr. Steve Chamberlain Collection. Very rare to fine gem crystals from this locale (I only ever remember seeing two other which were almost identical to this one, likely from the same pocket). Single terminated, very gemmy with richer red color at the termination. No damage. Unusual. 150$

OKI-461 Arfvedsonite Hurricane Mt., Conway, New Hampshire. Ex. Dr. Steve Chamberlain Collection. I classic site for this mineral. The specimen is a double terminated crystal measuring 3.1 x 1.5 x .7 cm. It is dark brow/ black with a high luster and poorly formed, almost fibrous, terminations. No damage. 60$

OKI-434 Quartz Scepter Fat Jack Mine, Lane Mountain, Bradshaw Range, Yavapai County, Arizona. Ex. Dr. Steve Chamberlain Collection. A nicely formed 3 cm scepter with classic form. The stem is milky while the complex cap is relatively clear. Minor attachment marks from once adjoining crystals on stem. No damage and nice aesthetics. 35$

OKI-435 Quartz pseudomorphs after Barite Grand Junction, Colorado. Ex. Dr. Steve Chamberlain Collection. I never knew this classic locality had pseudomorphs after its famous barite crystals, even though I’ve been there collecting. The specimen has a healed base and nice form. It consists of small, slightly diverging crystals in a packed group. The total length is 2.1 cm. Hematite red color and no damage. Here is your chance to own what must be a rare thing. 35$

OKI-436 Goethite Lake George, Colorado. Ex. Dr. Steve Chamberlain Collection. A fine TN spray of metallic silver and iridescent blue gray crystals. The cluster appears to be a floater (now glued in a perky box) composed of tiny metallic silver colored crystals with larger (to 1.2 cm each) spraying in all directions from their surfaces. 3.1 x 2.5 x 1.5 cm overall. An aesthetic example of normally very unattractive material. 38$

OKI-440 Goethite pseudomorphs after Pyrite Fields east of Fruitville Pike, 1 mile north of Lancaster, PA. Ex. Dr. Steve Chamberlain Collection. A fine red and gray pseudo floater with no damage. It measures 2.8 x 2 x 1.7 cm overall and is composed of two intergrown crystals. Nice. Unusual location. 25$

OKI-441 Hiddenite Hiddenite, Alexander Co., North Carolina. Ex. Dr. Steve Chamberlain Collection. A sweet little TN specimen from the classis U.S. locality written about in America’s Mineral Treasures. This little gem is 1.8 cm long, double terminated and of a brighter, more intense green color at its terminations. Not very big, but certainly a rare find. 190$

OKI-442 Malachite and Azurite New Cornelia Pit, Ajo, Pima County, Arizona. Ex. Dr. Steve Chamberlain Collection. Velvety looking, green pseudo after a large, curved faced azurite crystal. It appears that there was a later generation of azurites (to .7 cm each) in crisply formed crystals that deposited themselves after the malachite replacement was complete. 3.3 x 2 x 1.6 cm. Mounted in a perky box. Nice specimen from a desirable locale. 185$

OKI-444 Natrolite Chimmney Rock Quarry, Boundbrook, New Jersey. Ex. Dr. Steve Chamberlain Collection. A blocky crystal measuring 3.9 x .9 x .9 cm on edges. The interior is clear, gemmy, and much of the outer surfaces have a coating of an unknown species (I’d guess gyrolite) in small, lustrous crystals. Attractive piece with nice view of its internal clarity when viewed down the “c” axis. 60$

OKI-445 Pyrite Leonard Mine, Butte, Silver Bow Co., Montana. Ex. Dr. Steve Chamberlain Collection. A fine example from a classic locality noted for fine pyrites at one point in time. This plat of crystals is damage free and measures 3 x 2.2 x 1.3 cm overall. The luster, form and color are all great. Another North American classic. 40$

OKI-447 Pyrite Cornwall Iron Mine, Cornwall, Lebanon Co., PA. Ex. Dr. Steve Chamberlain Collection #88. Collected (purchased?) by Steve when he was a kid (and I was a year old). A fine, lustrous crystal with minor basal attachments and interesting form. Odd surface growth features. 2 x 1.6 x 1.1 cm. Old collection # on base so I think Steve must have silver picked this one. Another old classic east coast locality. 38$

OKI-448 Uraninite RESERVED Topsham, Maine. Ex. Dr. Steve Chamberlain Collection. Famous locality. 1.5 x 1.3 x 1.7 cm complete, double terminated crystal with minor basal attachment and no damage. A fine specimen with a n exceptional luster, steel gray color and great form. It looks more like a rutile from Graves Mt, GA than a uraninite! Exceptional radioactive specimen. 200$
