Don't be discouraged by the Lapis. It isn't a stone that tumbles easily, or well. The bloodstone, however, should be glossy by the time it runs thru polish. rockjunquie Agree with Randy's statement. Bloodstone is one of my favorite materials to tumble, as it usually produces a glassy shine. That's even with a rotary. Not meaning to steal from your thread, but here's an example from a rotary batch: I know it sure cabs well! Those are gorgeous! Maybe mine was stuck to the willow creek? Something went wrong. Nearly all of them polished ok at the 500.

Rockjunquie, I tumble hard material with some being flat on both sides and have found in a UV-18 that extra time will allow for a good polish on any flat side if at least 50% of the mix is media. I run 2 cycles on grit, 2 days on 500, 2 days on 1000, add DE to 1000 for 1 day, and finally at least 3 days for 14,000 for polish. All stages have borax added to the mix for hopefully better surface adhesion. Thank you What is DE? Diatomaceous earth?

DE is diatomaceous earth. I also use Tripoli. I mix 1/2 of add mix for 1000 to the unwashed 1000 and run one more day.
