Antique Optical Lens Earrings! These were part of a collection we received from an optician who practiced in St. Paul, MN, from the 20s-50s. We've made them into earrings and necklaces, and only have a few left! They have a 2.75" drop, and the lens measures 1.25" in diameter. This pair is thicker than the others we make, and can be used as a magnifying glass.
