These are lovely earrings and look good with greying hair (!) and a black top. I don't see any gold on them. They are about an inch long and the pearl is about a third of an inch wide. They are quite solid and the clasp looks sturdy.
I love them, they're absolutely mesmerizing whether it's the pearl or the ruby ones. I've gotten compliments on both of these pairs whenever I wear them out, and I love how delicate yet secure they feel.
