This batch started by cutting fractured faces on Harbor Freight tile saw, grinding them smooth(ish) on the edge of the blade, then tumbling in Thumler UV-18 vibratory tumbler:

120/220 grit - 36 hours
400 grit - 36 hours
800 grit - 2 days
1500 grit - 2 days
8000 grit - 2 days
22000 MA - 2 days

There are still minor cracks and fractures, but I like the resulting rounded facets. That UV-18 is FAST!!

I’ll post a before pic in the comments.
