Bubble stud earrings Bubble stud earrings Bubble stud earrings Sterling silver studs £19.00 These dainty silver bubbles are made from 100% recycled sterling silver. They measure about 5 or 6mm (this varies slightly for each pair). I can make these with a frosted satin finish, or a shiny silver finish - please let me know your preference in the message box at the checkout or I will send satin. These bubbles are absolutely the perfect finishing touch to any look. They are understated and contemporary, and might just be my new favourite earring.
