For jewelers who tend to think of metals as existing outside our gemstones, this page might come as a surprise. These unusual cabs contain copper, silver, or pyrite, in visible form. The stones have their own glimmer and gleam, making for all sorts of exciting design possibilities. Scroll down and savor, or click on one of the following choices:

Campbellite 

SOLD OUT.  MORE CAMPBELLITE COMING SOON!

This delightful stone has a field of creamy white interspersed with copper that has a bright metallic shine in some lights, and turns a beautiful wine red in others. From the Campbell Mine in Bisbee, Arizona.  Click on the photos for a better look.

Copper Fire Brick

This isn't an official "mineral," nor is it pure metal: It's the copper that stuck to the fire brick walls of the smelters in copper ore processing plants in Northern Michigan. It's really interesting material: Smooth and glimmery without being too shiny, with glints of red here and there, and the cream-colored mosaic pattern of fire brick chips caught forever in the metal. Most of these smelters are no longer in operation, so each cab contains a little bit of the history of the Upper Midwest. Each piece has the weight of metal, and a patina like antique copper. A really wonderful stone for people who work in, or just love, copper.

Copper and Black Fire Brick

It was very exciting for me to run across this stone--It was created just the same way as Copper Fire Brick, above, but the fire brick was blackened in the process, resulting in this elegant version. ATTENTION COLLECTORS: This stone is VERY rare--I only have a handful to offer. Click on the photos to see these beauties close up.

Native Silver and Cobalt

These are stunning stones, and just about impossible to photograph accurately. Just picture that any place in the stone that is not a creamy white or dark greyish black, is pure, highly polished silver that looks very smooth to the eye. The metal makes them heavier than usual, so they feel very substantial, as well. Click on photos to get a better look.


Native Silver, Cobalt     Canada
This is a very large, rugged piece, with greyish-white quartz at the top, some black in the lower half, and lots of silver all around.  37 x 27 mm  Click on photo to see detail.

MT135     $76.50


 


 


Native Silver, Cobalt    
Canada
This is a gorgeous piece with veins of grey-black surrounded by silver. It works vertically, too. 42 x 33 mm Click on photo to see detail.

Covellite

This should really be on my "rare finds" page, because it really IS rare: It comes from a closed mining area near Butte, Montana. It is probably the most unusual stone I've ever seen---It's a deep, metallic midnight blue all over, sprinkled with embedded particles of cool gold pyrite. NOTE: It is relatively soft and is not suitable for hard-wear jewelry.

At this time I can offer a limited supply of Covellite by two different cutters, John Mediz and Merlin DeShaw. These men are lapidarists who also mine some of their own material, and I'm proud to know them and offer their work here. Please note: Supplies are extremely limited.

Stones cut by John Mediz:


Covellite

27.5 x 20mm 8.04 g

Stones cut by Merlin DeShaw: Merlin's material is slightly different: The pyrite shows up in streaks and flows, instead of being dominated by dots, as John's is. Click on the photos for a better look.
