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.
This bracelet looks like it would cost $200 or more. The stone is beautiful and the silver etching around it is intricate! You should absolutely buy it. You can?t go wrong.
