Sapphire & light blue lucite encased in clear with a yellow center. These disc earrings are a great retro stud earring shape & a shiny finish. Just under 3/4" or 15mm in diameter, these button earrings are the perfect mix of classic and mod retro. The last pic showcases these same earrings so you could see the size & scale when they are worn. Worn by 'The Vintage Ginger'
