These incredible earrings are most likely unsigned Selro. I once had the matching clamper bracelet with purple stones and it had the hinge mechanism associated with Selro jewelry. The only markings on these are a patent number on the earring clips.
These are set in gold tone metal with swirls and filigree. There are light and dark green rhinestones and a large faux baroque pearl. One pearl has a very tiny spot of wear, otherwise these are in excellent condition. They measure 1.75 x .75 inches.
