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 have had these for a while. They are a graceful, long lived part of my collection. Simple but very useful. Have held up well and are very nicely done. Not heavy.
