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.
