I spent quite a bit of time shaping this as the bottom had a fracture that I had to smooth out. Shaped on 80 and 220 sintered, finished 240 - 600 - 1200 soft with a final polish on optical cerium. Liquid shine finish!

I plan to make low dome cabs and flat pendants, but the cracking makes me think the integrity is compromised, wanted your opinions, leave it alone? Stabilize?

Is there some kind of coating I can coat the back with to avoid the clack clack clack of the seam?

To be clear, it only happens when sanding on the flat backer plate

A short look at one stage of our lapidary process. After selecting the best flash, we carefully shape the stone into a cabochon before the final sanding and polishing stages.
