The jacket of these stud earrings sits in front of the lobe, unlike most styles. Made from gold plated sterling silver, the jacket is set with a twisting row of clear cz crystals that each measure 1mm in diameter. There are 8 stones per stud earring and this jacket section can be attached and removed as you wish to create two distinctive looks. However you wear them, be sure to secure them with their butterfly backs! The jacket measures 14mm high x 11mm deep and the studs are 3mm wide.
