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 would like to say that Matta is a very accomplished artist, she has a distinctly feminine style. I bought the peach pearl and peridot earrings and matching necklace and they are extremely beautiful and elegant. I am very happy with my purchase.
