Hi to everyone and thank you for your great & help with
my Argentium Silver tarnishing problem.
A customer of mine has asked me if I can “polish” her handmade
brooch, made by another silversmith. The brooch is comprised of
sterling silver & 18kt.
gold, with three chrysocolla druzy, sodalite, & a
carnelian. The sterling silver pierced design is very tarnished and
also a sandblasted, very rough surface, silver. Ultrasonic cleaner?
Thank you all so much.
