Frosted slate blue donut ring studs measuring about 15mm. Smokey frosted lucite in a great shape, very light weight.
Most all earrings are made with vintage lucite parts that were made in Rhode Island in the 1960's - early 80's by Best Plastics. We hand-set them with surgical steel earring posts and they have sturdy surgical steel/acrylic backings on them as well. Light-weight & fun to wear.
