These funky little earrings are sterling silver and are 5/16 inch (8mm) across. They are round and concave, so they catch the light and look sparkly. The inside is textured, contrasting with the super shiny edge. I used thicker silver this time, so it's a slightly chunkier pair of earrings. Perfect for work or if you like smaller earrings. Comes in a small gift box. Easy to clean with silver dip.
