My current batch of amethyst, Smokey quartz, carnelian and green aventurine is advancing nicely in the tumbler. This video shows me unloading them from the 1200 grit and putting them back in again for the tine oxide - the final step!
I'll apologise for the video quality - I am trialing a new go-pro style camera and I am wearing it on my head so you get the same view I do. More videos coming using the grinding wheels and working with other tools and crystals.
These little beauties are coming along nicely and will be ready next week.
Hope you enjoy!
