Vintage Lisner Blue Rhinestone Clip On Earrings

These are adorable Lisner earrings from the 1950s to early 1960s. They're clip-ons with Lisner stamped on the backs. They're set with light blue rhinestones. The center stone on one is slightly smaller than the other side. I think this is a manufacturing flaw or possibly an old replacement. The earrings are 1"x1" and have just a little metal wear common with age.
