Ever wonder how to polish a flat chalcedony agate slab? In this fast-paced 5-minute lapidary tutorial, I take a beautiful chunk of chalcedony I found on my Central Arizona rockhounding adventure and show you how to polish it perfectly using a flat lap grinder.
We’ll go step-by-step through the entire process of chalcedony polishing—starting with Sharpie prep, smoothing out tile saw cuts, and using each polishing disc: from 180 grit to the brown disc and finishing with a felt pad and aluminum oxide. This quick DIY guide is packed with tips for polishing chalcedony, using a flat lap properly, and getting that flawless, mirror-like finish on your rocks.
If you're getting into rock polishing or just love a good lapidary transformation, you're in the right place. Learn how to polish chalcedony, see the shine reveal, and catch those stunning inner patterns as they come to life.
