Rotary Rock Tumbling Onyx – Process & Techniques

This is one in a series of Rock Tumbling “How-To” videos that I have been posting on YouTube. This video features me tumbling Onyx! This particular batch of Onyx had gorgeous color bands, so I am calling it “Fancy Onyx”. Onyx can be confused with tumbled Obsidian or Black Tourmaline, but it is not nearly so fragile. It is Mohs hardness 7, and is not brittle in the tumbler, so it is great for a beginner tumbler.

Check out the video below to watch my entire process, see the final recipe and timeline I used, then see the super shiny finished, polished Fancy Onyx!
