These sweet little earring jackets are meant for layering, bringing a little more pop and impact to my mini gemstone studs and any other tiny stud earrings that you love. They are double sided with a milgrain textured side and a flat polished side and are available in both sterling silver and gold filled. They're tiny jackets - only 6mm or so - and so will only work with tiny studs and on the front of the ear.
