Description : Earrings for pierced ears with a hinged lever clasp for security. Classic marguerite or flower shape with a central emerald surrounded by a border of diamonds.
The emeralds are cushion cuts, rounded rectangles. Old mine cut diamonds of a very nice size and rich look. Diamonds set in gold form little petals around the central emerald.
Beautiful quality stones with lovely color to the emeralds.
The gems are clearly from the 19th century, but I believe that the wires were replaced early in the 1900's. The posts with clips are very secure.
