I’ve just finished cutting a large oval turquoise cab and
bezel-setting it into a sterling silver ring. In the course of that, I
met with a recurring problem, actually a set of problems, namely,
scratching the stone when cleaning up the top of the bezel, and
getting the bezel top perfectly smooth even and uniform.
Normally, I’d use a fine file with one safe side, and go over the top
of the bezel with this, the safe side against the stone. However, even
that is not entirely safe; even the “safe” side of the file at times
leaves marks on stones like labradorite, opal, chrysocolla, malachite
etc. And apart from that, the bezel top is still not as uniform as I’d
like it to be. In short, getting that bezel top smooth and clean and
even is still a challenge to my (largely self-taught) ingenuity.
So I’m wondering what tricks and techniques orchideans might have up
their collective sleeves. I’ve tried the pink (ultra-fine) knife-edge
abrasive wheels in the the foredom but can’t seem to get the motion so
uniform that it leaves a fully even surface. What else should I be
doing or trying?
All hints & tips & suggestions gratefully and humbly accepted!
