I am a recent owner of the H. Stern stars ring
, and am worried that I will ruin the finish if I try cleaning it like I usually would. I don't seem to have these worries with any of my other gold pieces, since the ring is fashioned in "darkened" 18k gold. It is kind of like the gold's equivalent to oxidized silver, I guess?
Anyways, how should I clean it?
Thanks!!!!
