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.
These earrings are delicate and very pretty and unique. The hook is rather thin, however, and fragile . Nonetheless they are beautiful so I’m not going to worry about it.
