We have cut this beauty and have started tumbling it today. My husband (Anthony) and I are self taught rock tumblers, we really only know what we have read and what we have learned through trial and a ton of error. From experience, I can tell you it's is fun, it can be a lot of work, and sometimes it is down right heart breaking!! We use both rotary and vibrating tumblers. For the Bumblebee Jasper, we will be using only the rotary tumblers so, it will be at least 4 weeks before they are finished. For the most part, we are always tumbling something. We also have blue and gold tiger eye tumbling as well.
