Cliff Mine, Pheonix, Keweenaw County
16.1 x 2 x .5 CM (cabinet)
An antique native copper "finger" or "fan blade" made by skilled hand chiseling long ago. These artifacts were made by miners from the often huge masses of pure Copper encountered in the Upper Penninsula of Michigan. From the John Marshall collection, this is recorded as from the Cliff Mine, such attributions of these artifacts are quite uncommon. Aside from the very hard labor of hammering through solid copper, these fingers required a lot of skill to create such a long straight and clean blade. While not a typical mineral specimen this is a very much a classic Native Copper that has had a major trimming job!
Grand Reef Mine - Graham County
4.1 x 2.9 x 1.8 CM (miniature)
A miniature from the Grand Reef Mine hosting milky white Cerussites with the habit that looks much like a doubly terminated Quartz. The Cerussites are on a typical druzy Quartz matrix and are in very good condition. A nice locality piece, the Grand Reef Mine is well respected as a source of some uncommon Lead secondary minerals.
Elmwood Mine, Carthage
5.3 x 3 x 2.8 CM (small cabinet/ large miniature)
An especially fine, perfect and odd "Carthage Corner" Fluorite that is almost colorless but with a hint of purple in person. These strange etched crystal corners are quite incredible and distinctive for the Elmwood mines. This one is especially exotic with extra finger-like growths one edge which also look like tiny "corners". The specimen is displayable from all sides and the geometric etchings are as sharp as any I have seen. An American classic and a choice Fluorite for any suite. Even better in person.
A new find of classic habit from pockets opened in late summer 2019. These very richly colored and well crystalized Amazonites follow in the fine tradition of fine Colorado Feldspars. Well above average intense deep blue-green color and bright luster, these crystals are translucent and the condition is fine.

This piece has rich color zoning in person and the edges are remarkably distinct, sharp and clean.
Siegenite on Galena
West Fork Mine, Reynolds County
4.3 x 3.7 x 4.4 CM (miniature)
Rich growth of Siegenite crystals on Galena which is in cubes, modified cubes and octahedrons. Quite esthetic for this rare mineral (Cobalt Nickel Sulfide). Ex collections of Steven Chamberlain obtained from the Lendall Hill collection. Fine contrast and with many excellent display angles.
A super esthetic older piece from finds made more than 50 years ago (predating the famed Lees pocket). This is in flawless condition the cluster of Barites has fine steel blue color and contrasts with a yellowish Calcite matrix. In addition to the nice arrangement some of the Barite faces show a very unusual etching pattern seen in some photos here. Lots of visual impact for the size, the color is a bit richer than the more recent finds, all in all far better than "above average", an excellent old time Colorado specimen.
A single, sharp terminated crystal of Epidote. At this locale these are often found to be zoned with Clinozoisite but usually not more than 50% hence the Epidote label. From the long closed now classic locale of the VAG mine in Northern Vermont, USA. A fine clean translucent to transparent crystal in fine shape from the Rodingite zone famed for world class Garnets. Lustrous, undamaged and with distinctive striations, a choice little classic Northeastern US piece.
