Polishing stones


#1

Hi all,

I have some cheap synthetic facet cut stones, those facets are not so
good polished. The stones themselves are very clear, but the reflected
light is not bright. I have a flex shaft, but don’t have a stone
faceting machine. Can I polish those stones with diamond polishes or
powder? I don’t need accurate cut and don’t mind if the facets become
somewhat being curved.

Thank you very much for answering my question about the electric

soldering machine the other day.

Hi Takahashi,

The brightness of a faceted stone is more dependent on the angles &
arrangement the facets are cut at than the polish. That’s not to say
that the polish on the facets doesn’t affect the appearance of the
stone.

Unless you’ve got a very steady hand, you’ll probably have trouble
using a hand held flex shaft tool to improve the polish. It might be
possible to improve the polish on an isolated facet or 2, but over
all my guess is that you’d have problems.

Facet stones are best re-polished using a faceting machine. Even
then getting the stone properly aligned can be time consuming.
