Im sure there may be something already discussed on this one but
anyway. Customer has a large brooch (1.5"di.) made of amber. I
removed it easily from the setting.
I tested - it is amber. Has some chips in it they want “sanded” out
and polished. The amber is a big round cabochon shape with an
intaglio carving on backside. The edges that are under the setting
are chipped and I need to know what to use to sand and polish. What
compound will do this??
