Rotary Rock Tumbling Blue Aventurine – 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 Blue Aventurine! Blue Aventurine is a light blue colored stone that is part of the Aventurine and Quartz families. The distinguishing factor between Aventurine and Quartz is the inlclusions of mica in Aventurine that give it a sparkly, shimmery appearance. The mica in the Aventurine can make tumbling it more tricky. The mica is much softer than the Quartz and may undercut on the surface leaving micro-pits that prevent Aventurine from getting a good shine – this all depends on the amount of mica in your rough. Therefore, Tumbling Blue Aventurine is an Intermediate level project.
Check out the video below to watch my entire process and see the final shine of this gorgeous Blue Aventurine!
