A Geode Experiment

Curious minds want to know: What does the Outside of a Geode look like Tumbled in a Rock Tumbler?

I begin an experiment to discover what the outside of a geode looks like when it has been tumbled and polished.
Before I do that, I must first empty the contents that I have been tumbling for the past few weeks to figure out which of my 2 tumblers contain the polish and which contains the courser pre-polish.
My first batch of polished stones is completed, my second is being polished up, and the Geode begins its transformation.
