Vintage LERU Thermoset Rhinestone Earrings

Vintage item from the 1950s. Pearlized beige thermoset plastic clip back earrings with prong set rhinestones. The earrings have filigree clip backs. Signed LERU. NOTE: Some of the rhinestones have darkened due to age. Also, note that one rhinestone on the left, has been replaced at some point, with just the rhinestone, without the little four-prong setting ( see 3rd photo).
