Just recently finished tumbling a batch of Dyed Crackle Quartz. I used rotary tumblers from start to finish. They are a little on the rough side because I only ran them through Stage 1 one time due to a lot of the color dissipating and I wanted to keep them colored.

Really pretty! I've often wondered what this material would look like tumbled. You definitely nailed the sparkle and shine with the intense color intact.
Nicely done!
