I’m looking to see if anyone has information on polishing goldstone. I’m having little success with diamond polishing paste, and after doing some research and reading that glass is best polished with Cerium Oxide I ordered some paste and powder with an average micron of 1.2 to see if that works.
The goldstone we’re using is a cab in a silver bezel setting. We’re using multiple sizes and are trying to avoid touching the goldstone with our buffs, but when we polish our 10mm settings there is some contact made by the buff every now and then. This puts a haze on the goldstone. The stone also seems to have a coating applied to it from our vendor. We learned that if steam comes in contact with the goldstone, it leaves a matte finish on the stone. We’re assuming this might be due to the factory coating being removed from the steam. We started using diamond paste with a felt wheel to limited success. Next step will be trying the cerium oxide.
If I could get some input on a few things it would be greatly appreciated:
-How firm of a felt wheel should we be using? We have “hard” on hand, but it seems to periodically be leaving flat spots on the cabs. I’m assuming a soft felt wheel would be better.
-Does anyone have any experience on polishing goldstone cabs, and what advice could you offer?
I appreciate any input. First time posting, long time reader.
