Here's some more cabochons, it seems my large grit disks are wearing out quickly, so maybe it's time to upgrade to the fabric they use for belt sanders...
Bronzite from Australia. This stuff doesn't seem like it's straight amphibolite, since there's chalcedony and ironstone concretions running through it. Has some impressive spangles when you rock it, but since I cut this cabochon upside-down they are concentrated at the girdle.
Botswana Agate. Was hoping this would show some parralax effects when it was done, but the transparent zones are too cloudy for anything like that, it's a nice pink however.
Black Chatoyant Sunstone from Tanzania. The eye from the fibers was kind of over-exposing my camera when taking this shot. It's also an adularescent material so you can see a weak blue secondary eye on the right from that phenomena filtering through the fiber. I also have a backlit image to show off the inclusions and transparency, would you believe that in pieces with sparser inclusions you can get decent light return in a faceted stone?
