A toenail-sized specimen of silver from the old White Pine Mine in Michigan, not flimsy but actually quite substantial. 3.4 x 1.8 x .2 cm
This is an old, nugget-style silver/copper halfbreed from Calumet. A nice, thick 2-cm chunk of silver crowns the top of the specimen, with copper forming a natural “base.” Very sculptural. Came with an old Prosper Williams label. 5.7 x 3.6 x 1.7 cm
A classic thumbnail specimen of beautiful (small) silver wires on matrix from Kongsberg, Norway. 2.0 x 1.6 x 1.2 cm
This is a sheet of native silver still embedded in its matrix of bornite! The sheet of silver is not flimsy, but quite substantial; the bornite has a pretty irridescence to it. 5.1 x 3 x 1.7 cm
An aesthetic thumbnail nest of lustrous silver wires from the recent find at the Imiter Mine in Morocco. These wires look very similar to Kongsberg or Freiberg silver wires. 1.7 x 1.6 x 1.0 cm
This is the most sculptural of the small lot of Keweenaw Peninsula silver and copper "half-breeds" that I purchased a couple of years ago. The silver is shaped like a boot or sock. It is also unusual, in that, there is far more silver than copper. Typically, there is more copper than silver.. Here, this hefty thumbnal nugget has more silver than copper. 2.0 x 1.8 x 0.3 cm
This is a substantial (not flimsy) sheet of silver still embedded in its bornite matrix. The bornite is a pretty, irridescent purple and blue. In the pic, the grayish material between the two chunks of bornite is the sheet of silver, which extends as a vein inside both bornite chunks, so it is the size of the entire specimen. 4.7 x 4.4 x 1.6 cm
This is really quite a good specimen. To see Silver in such an unusual habit, even knowing that it is a pseudomorph, is eye catching and mind boggling. The luster of the fine Silver crystals is very good. This is an excellent thumb with great aesthetics 2.5 x 2.1 x 1.3 cm
An amazingly large and sharp crystal of silver sitting on a bed of smaller crystals, all sprinkled with tiny Silvers and Pyrargyrites. Even though this is a thumb, that single large crystal is impressive for any silver specimen. Really quite remarkable. 1.7 x .8 x .7 cm
This “Lariat” of wire Silver is excellent for any Silver from anywhere, but it is a great specimen for the location. Delicate and aesthetic, this is a particularly cute thumb! 2 x 1.1 x 1 cm
2.5 x 2.5 x 1.0 cm. A fine copper specimen from the Turjinskii Mine of the Urals. Two diverging columns of sharp copper crystals rise up from the main shaft, which includes a very sharp copper octahedron. One column is capped by a horizontal, 1.4 cm spinel twin. All of the crystals have fine patina and lustre. The piece is partly intergrown with native silver and a bit of quartz. Dating to the 1800s. Ex. St. Aubyn College, Richard Barstow and George Elling Collections.
It is almost impossible to find a well-balanced, MATRIX Kongsberg in ANY size but a thumbnail is exceptionally rare compared to larger specimens. Elegant series of flowing wires with superb luster and aesthetics literally leap off this rock matrix. And it’s a Kongsberg! SUPER silver thumb with real elegance! 2.7 x 2.2 x 1.5 cm
This large copper-silver “halfbreed” is from the world renowned, but long depleted, copper deposit in the Upper Peninsula of Michigan. The specimen is a slightly rounded nugget with good eye appeal. With the unusual silver knob atop, it is a very compelling specimen and unusual in teh richness of both metals without showing intermixing. Over 9 ounces, or 265 grams! 8.3 x 4.6 x 2 cm
A branching specimen of native silver, from old mining in Cobalt, Ontario, Canada. Just over half an ounce in weight! 7.3 x 2.8 x 2.6 cm
An extremely rich and showy ore specimen of a slabbed and polished face of dendritic silver in quartz from Creede, Colorado. This is a superb, old-time Colorado piece and is seldom available in this quality. Ex Richard Hauck Collection. The weight is 79 grams or nearly 3 ounces, most of it silver! 4.9 x 3.2 x 3.0 cm
