Vintage specimen (1920-30 era) of fine twisted and tangled native Silver wires filling spaces between Barite crystals. From the White Raven Mine, (Boulder Colorado area) Ex Wards with George M English type label. In fine condition, and spectacular under magnification this is a classic combo for this locale. Close exam finds a few Acanthite crystals and rhombs of Siderite, the Silver has a dark patina overall. Rarely available antique and very uncommon in this quality.
Native Silver and Copper

Early summer 2023
A USA classic Silver-Copper ex Johannson collection. The Silver is in crude crystals and masses most of which protrude from the Copper. The thin sheet of metal is is from .8 to 1.2 CM thick, but weighs a hefty 124 grams, which indicates a high percentage of Silver. There is no mine attribution in the collection notes but this was obtained in the late 1940 era by trade.
A superb older specimen from the great Silver discoveries at Batopillas. Ex Behier collection, this is textbook perfect example of a single elongated, twisted spinel-twin crystal with a secondary addition of a few smaller crystals like a crown or hat. This looks a bit like a palm tree from some angles. Close exam shows the shaft or trunk has the herringbone form visible which is characteristic of this locality. In perfect condition the specimen displays well on every angle. Small but with great display impact.
Silver - classic German locale
Freiberg District, Mittlesachsen
4.6 x 3.3 x 1.6 CM (miniature)
Early summer 2021
A complex tangle of Silver wires and ropy masses rises from a pure Silver matrix composed of smaller wires. An old piece from the classic Freiberg district, this is an especially fine example of several wire forms and has a great overall esthetic. A vintage Deyrolles (Paris) label is included, however the specimen age is not known (Freiberg produced Silver since the 12th century, the last mine closed over a half century ago). In fine condition and with a mix of patina, most is a dark silver-black but there are zones of brighter golden luster which gives great contrast.

Himmelsfurst Mine, Brand Erbisdorf, Freiberg district, Erzgebirge
8.4 x 3.4 x .5 CM (cabinet)
new year 2021
A long, slender tapering wire Silver from the classic Himmelsfurst Mine. The wire if straightened out would be roughly 18 CM long which is sizable for one of these. Very slender overall, at the very end it is just .2 MM thick while at the base it is about 3mm. there is a bifurcation in the lower section that is rather unusual. Nice patina throughout.

Caledonia Mine, Mass City, Ontonagon County
2.2 x 1.7 x 1.2 CM (thumbnail)
new year 2021
A US classic a choice Halfbreed of Silver and Copper that shows perfectly the two metallic colors with very bright luster. Looks fine on all sides, the Halfbreed masses from this region are unlike anything from other places. The copper mined in the Upper Pennisula of Michigan tended to have some small percentage of Silver mixed in. This was especially desirable in the early manufacturing of electrical wires.
Native Silver (Sheet form)
Eisleben, Mansfeld Basin
7.6 x 2.6 x 1.9 CM (cabinet)
One of the more odd forms of Silver are these thin sheets, almost like a Silver foil found in narrow seams of Slate. Very old material, these were mostly extracted in the early 1900's, the locality is a German classic. The Slate matrix is Copper bearing which is an unusual host for Silver anyplace. The Silver leaf is partly peeling from the matrix and shows the delicate form, being under .05MM thick.
SOLD Silver and Copper
stock #SOLD LH-702
6.7 x 3.1 x 1.7 CM (cabinet)
A hackly mass of Copper holds some areas of crudely crystalline Silver. The largest zone of Silver also has a few areas of Copper growing on the Ag which is less common than the other way round. A good mixed native element specimen from the Hitchings collection that he obtained in 1970. This sort of association is unique to the upper Pennisula of Michigan.
