These earrings have so much sparkle! The stone diameter is 8mm, appx. 3/8". Set in shiny silver-tone, hematite-tone, and rose gold-tone round bezel settings. Post closure. These are really versatile and I'm sure will be a new favorite! In stock and ready to ship out. Comes in a gift box for easy gift-giving. They're so fun though, you might be tempted to keep them for yourself!
