Crafted from 14k gold over sterling silver, the pieces in our Delicate Collection are future keepsakes meant to be layered and worn every single day (think of them as your jewelry BFFs). Show your lobes a little love with these tiny heart-shaped stud earrings. 4 1/2 mm x 4 1/2 mm. 14k gold-plated sterling silver. Sterling silver posts. Sterling silver posts are naturally soft due to the high silver content (just bend 'em back into shape if they get out of whack).
