You can use Zam on coral as well as other soft stones- you may
want to sand out any scratches or other blemishes first.

I have an older cabochon coral ring that has lost its luster. Since
coral is soft, what is/are the best way/s to polish it?

Thomas,

You didn’t specify what kind of coral it is…but presuming it is
either black or red, use ZAM with plain cotton muslin buff running
at high speed. Use light pressure but keep the buff loaded.

If there are scratchs use wet/dry sandpaper starting at 600 grit
then progressing to 1200 grit. Then use ZAM on a clean muslin wheel.

Believe it or not- in Mexico they used that brass polish in the pink
fuzzy stuff in the can for black coral to give it a high shine.
(Duraglit?? Something like that) Worked like a charm. So should work
on the pink stuff as well,… might be worth a try. Worked on the
black coral I carved,…
