This super miniature features a sharp, doubly-terminated, 1.4-cm crystal well-exposed on the surface of massive calcite, and also shows off a much fatter, half-buried, 1.5-cm-long crystal with a very nice, fat termination. Zincite is rare in nature, and the crystals from this mine, from the old workings, are simply the best. More than that, it is from the type locality and this label notes the piece to that era when the mine wsa known by the physical furnace or the initial mining town itself, which later grew into the larger Franklin mine. Ex Otto Runge collection (1941) to DC Gabriel collection, donated to Seaman Museum and then later exchanged out of the museum about a decade ago.
ex. George Elling
This specimen features two doublet clusters of doubly-terminated willemites, each about 4 cm, flanking a large section of massive calcite matrix. Actually, you can see there are other willemites embedded within. The contrast, when shot with ultraviolet light, is stark and dramatic as you can see. This is an old specimen, from the stock of Arthur Montgomery (1909-1999), well known field collector and dealer. His label dates it to (1937-1941). Until recently in the George Elling Frankli Collection
ex. Richard Hauck
A VERY rich specimen of the extremely rare mineral species named after noted Franklin area collector Richard Hauck, consisting of a VERY RICH coating of dozens of eye-visible sub-mm microcrystals on contrasting matrix (all the pink stuffin the middle), with contrasting Pyrochroite (Black) in association . Almost seventy new mineral species have been described from the unique Franklin area, and this is one that remains unique to Sterling Hill, to my knowledge. It would be considered quite a good specimen! 1100 stope, 900 Level, Sterling Mine, Ogdensburg, Sussex County, New Jersey. ex. Richard Hauck Collection to NJ collector James Zigras, and then exchanged to me. From Richard Gunter, an addition: The Hauckite sample from Sterling Hill that you have as USA-87 is part of a very rich mineral paragenesis with several other phases associated. Similar samples are part of Palache's Fluoborite suite with Mooreite associated. My sample is from C. Key bought in 1979 as Fluoborite-Mooreite with the Hauckite listed as "yellow, bladed unknown". There are several other phases on the sample that resemble Torreyite (white to light blue masses) and possible Lawsonbauerite (flexible bundles of fibres stained brown). Very small bright red crystals may be Zincite but I am not sure. There are also a couple of other phases that I have not been able to identify. Maybe someday.
A superb, rich micro specimen of this very rare species, . A note on the bottom reads "exceptional - 10 clusters." ex. Neal Yedlin Collection. TYPE LOCALITY
An extremely rich example of pyromorphite from this rare locality, both well covered and with excellent color.
Here we have a pastel-green Prehnite cast after Anhydrite where the original anhydrite crystal has completely vanished, leaving the hollow prehnite behind. These are old specimens, mid-1900s mainly, and this is a SUPER example in large size of the style. It is pristine and complete all around the termination, not broken at the tips as most are. It has a really nice pastel hue in person, that is somewhat pale in the photos. Also, it is nice and sparkly, very pretty.
A MAJOR specimen from this important, classic garnet locality on the East coast, with robust, 3-dimensional, golfball-like crystals in matrix of quartz and muscovite. The large crystal is 3.5 cm. Contacted on back, the piece is complete on the front. This is a dramatic display specimen of something very hard to come by. When I do see them, on the East Coast at shows, they are often accompanied by prices with an extra zero added on, to my more worldwide way of thinking about the market. But they are rare, and important additions to East Coast specialists, and so treasured. In the late 1800s, Daniel Clark and FS Johnson worked a pegmatite that produced these, but no precise locality was given...today they are known as "Russell" garnets for a nearby town.

This is a HUGE, incredibly intact, 855-gram SINGLE CRYSTAL of willemite! It is a very old specimen, certainly from the 1800s. The crystal is complete all around, fully terminated, and just...BIG! It has several old labels, the first in old script from an unknown collector, and the second being a display label from the early days of the Seaman Museum collection in Michigan. It was exchanged out at some point, and ended up in the noted Franklin collection of George Elling, from whom I exchanged it myself recently. A third label with the specimen notes that it came originally from the collection of Washington Roebling, but I have no proof of that (yet). I have never seen the likes of this kind of a willemite, for sale, and we both consider it a major US classic.

I found this specimen, of all places, for sale at the Munich show. Things get around, as they say! This extremely rich, large , cabinet specimen is one of the prettier Bristol chalcocites around, for the rich crystallization set starkly upon contrasting quartz crystalline matrix. The crystallised matrix is uncommon, and really offsets the matte black chalcocite nicely. The clusters are very 3-dimensional and dramatic , upon it. Also, small green flecks of malachite or bornite perhaps, seem to be present. Commercial mining began in 1837 and carried on until 1953 (according to MINDAT) - this mine was a hugely important US resource through the Civil War years and beyond, and collectors lament its closing.
ex. Ken Hollman
A good, sharp, lustrous epidote crystal, wihtout alteration to garnets or diopside as is typical here. ex. Ken Hollman Collection (and self-collected by him)
ex. Ken Hollman
A rare replacement, classic for this locality! This is a super specimen with a large, 3-dimensional, sharp crystal at the top of a cluster of smaller ones. The Grossular garnet has completely replaced a former epidote crystal cluster. Diopside crystals deposited later, accent the termination. Although there is a slight contact to the right side of the replaced epidote termination, the termination is basically complete, and sure looks complete at first glance. Again, it is a very choice example for the style because of the sharpness of crystal habit here. ex. Ken Hollman Collection
ex. Dan Ehrling
This is a significant, and surprisingly large, crystal of Chondrodite from the old Tilly Foster Mine. According to MINDAT: Large iron ore (magnetite) deposit discovered in 1810. The mine was 600 feet deep in 1879. Mining ceased in 1897, after 13 miners were killed in a rockslide. Specimens today are obviously hard to come by, and I know people who are dedicated to collecting Tilly material. This crystal is 2.7 cm long, and has excellent deep color and lustre for its size. The left termination is complete, though there is some contacting and a small break at the right edge, where it may once have been doubly-terminated. Still, large and significant for the locality. VERY OLD classic, ex. Dan Ehrling Collection (Milwaukee, WI), acquired in a trade with the University of Chicago in the late 1960s and early 1970s in exchange for his African material.
ex. Ken Hollman
Because it is a cluster, and large, this is a really good example of this rare replacement! Grossular garnet has completely replaced a former epidote crystal cluster (floater, with the largest crystal 7 cm and doubly-terminated). On the grossular, later-formed diopside crystals have grown. The whole thing was encased in, and dissolved out of, calcite by the collector (Ken Hollman). In good shape and complete all around except for two small damage spots at the top right and top-left of the large crystal's termination (or this would be twice the price, as well). ex. Ken Hollman Collection

This is a very hefty, showy, and unusually large, example from this hard-to-get locality. These magnetites to me are best of species - I know some will disagree, choosing instead the sharp Swiss octohedra. But, for me, i like the metallic, jet black, complex cubes of the NY Magnetites better - and the specimens are larger and more pretty, overall, too. This is a major classic but more than that something really different for a common species normally relegated to the drawers and not to display in a showcase. This is part of a larger piece formerly in the State Museum of NY, traded out to Ken Hollman. When I got it, it had not been prepped yet to remove the calcite and expose all the crystals. This calcite coating did protect many crystals, and several of the major ones (to 1.5 cm) are indeed pristine, though there is damage to smaller crystals and to larger crystals on the periphery. Nevertheless, an impressive specimen and price adjusted to give a good deal based on the presence of damage scattered about. ex. Ken Hollman Collection
A MAJOR old specimen with a HUGE, 7-cm-long chalcopyrite crystal on which rests a cluster of quartz, and then another, smaller but sharper, chalcopyrite! this is a classic old locality, from which specimens seldom turn up today (the mine was shut in 1932). This particular specimen is a stunningly large chalcopyrite for any US locality - I cannot think of a larger crystal from other places in the States. It is in great condition considering its size and age, with just a small amount of edge wear to the patina coating. Note it has not been cleaned. A little chemistry, and that black patina would probably come off to reveal a gleaming golden crystal underneath, making it both big and beautiful.
