These clip-ons are signed "ROBERT ROSE" and are quite substantial; measuring 2 1/2" x 1 1/4".  The turtles have a variety of stones and a metal rose on their backs, connected by a wire.  The clip part of the earring is adorned by a glass cabochon.  The one cabochon has a crack through it, but upon very close inspection, it appears that it may have been a manufacturer's flaw and does not appear to be loose or flaked.  These funky earrings are in very good condition.
