An oddly ASYMMETRIC piece, which is most unusual for this find, showcasing dramatic flanges more to one side than the other, at the base. Very stark and dramatic! The width at the base highlights the 3-dimensional sharpness of the upper portion of the twin!
A remarkably sharp specimen like a needle, with beautiful elegant tapering to teh tip! The side shown is not the best, i now notice...the other side shows more symmetric twinning along the central plane. so, a bargain...
A visually stunning, curved specimen showing dramatic secondary crystallization that is the most complexly symmetric of the lot, when such has occured. the lateral orientation of the crystals on the secondary growth is really enhancing of the sharp central twinning, and the centrla twin has extra-thick flanges as a result that really draw the eye inward to the point. One of my favorites of the lot!
An excellent large twin, with sharp flanges aside the main axis - note the unusual extended crystal atop, for example! A very fine, large speicmen at a fair price, i would say
A slender, elegant crystal with deep twin crevasses along all sides, just razor sharp!
WONDERFUL, large, and elegant small cab with a graceful curvature and tapering to it that is really unusual in the lot!
An exquisite specimen of finely crystallized copper! This piece has 3-dimensional, thick, spineltwinned crystals and is also aesthetic...It is rare in such quality, from the 1800s and these mines. Ex. Mark Rodgers Collection to Kristalle to Dr. Mark Feinglos Collection
A remarkable locality piece - BUTTE coppers are VERY scarce. This is a legitimate specimen with documentation that it was collected by a prominent Butte collector in teh 1960s. I obtained it in trade from another prominent Butte collector, and he provided a label and the story. It ain't pretty, but it IS significant for this important mine!

A magnificent, very arboreal-looking cluster of THICK copper crystals, forming a solid tree rising from the quartz matrix. This is a dramatic and exceptional piece with a lot of character, and is MUCH MUCH better in person than it appears. It came to me in trade with Gene Meieran, in whose collection it resided after he made a trade with the Seaman Museum. Courtesy of curator George Robinson, I can say that the piece came to the museum "some time after 1917." Hubbard died in 1933. There's general information on Hubbard given in the MR "copper country" issue in the section at the end on the Museum's various collections.

WOW! Silver CRYSTALS to over 1 cm are here perched in a protected cavity of a HUGE, if somewhat lumpy and rounded, copper crystal! The association is really pretty impressive, and it is much better in person. The bright contrast makes it stand out from most silver/copper combos and there is no intermixing of the two elements as is more common.

A very elegant , large cluster of conjoined spinel twin crystals from this famous locality. This is not from a recent find of the late 90s with smaller crystals, but rather from an older find of the 1980s

A crudely formed copper crystal with very minor prehnite has become the matrix for two VERY SHARP, feather-like, aesthetic growths of native silver to 2.5 cm in length. This silver growth is reminiscent of classic specimens from this Kearsarge Amygdaloidal Lode. This combination of copper and silver, while not uncommon, makes for a superb minature because it IS uncommon in aesthetic specimens with well crysatllized silver atop. Usually, the mixes are just lumps. This one is stunning!
Bisbee is famous for its copper minerals, but copper specimens are relatively more rare than azurite and malachite for some reason. This is a gorgeous miniature, with complex and subtle patina and color variations. Several crystal habits, including spinel twins, are present. The colors in person are red to yellow-red, and the lustre is high. Overall, a highly unusual specimen that stands up like a tree, perched on a bit of gossan matrix.

Copper replacements of azurite from this small mine are world-famous for their uniqueness and form. However, they are very rare, and frankly usually not all that sharp in crystal form (due to both nature's lack of fidelity in replacing azurite by copper, making the edges rounded; and wear over time). I am told that many are quite old, certainly pre-1960s. Of all that I have seen and handled, this piece has the sharpest, best preserved crystals. It was formerly in the noted collection of Bob Jones, who is now the senior editor of Rock and Gem Magazine. Due to its superb qualities relative to the others I have seen, I do value this veryhighly. To me, it stands way above the crowd. As well, its a helluva interesting replacement that you do not find elsewhere.
