Q. I had a similar thing happen to my sterling silver ring. I left it in hydrogen peroxide (3%) a bit too long, and it turned the sterling silver black. Is there anything I can do to remove the tarnish & have the sterling silver shining again?

Q. Yes, hydrogen peroxide does react with ANY type of silver.
It will oxidise it very quickly.

Ed. note: try the washing soda [on eBay or Amazon] and aluminum foil procedure described in letter no. 4785, Bruce.

A. Use toothpaste and a toothbrush to brush the black off. (Not tooth gel or charcoal. Just good old fashioned tooth paste). Instant effects.this also works if you bleach gold.
