Blue & grey studs with an almost tie-dyed bursting blue sky pattern. This style is known as the 'Retro Button Studs' and each measures about 13mm or 1/2" in diameter.
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.
