These are amazing! These earrings are gold over sterling set with larimar, amethyst and a greenish druzy crystal. These are bold, large and unique. They are post and lever back. Signed "RMC" 925 on the backs. They measure 2 1/2 inches long and 1 1/4 inch wide. The tops look like a blazing sun, the amethyst is like a satellite moon. They are comfortable on.
