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 even nicer than in the photo. Light to wear but look substantial and lays nicely. Gold is bright and the design is subtle but eye catching. A nice quality piece to wear often.
