These sterling silver, open hoop studs are perfect for stacking when you have multiple piercings as their small size can be worn in any position on the ear. The open 2/3 hoops are 10mm tall x 8mm deep and measure just 4mm across at the widest point on the outer circumference. Each one is set with a single moonstone and decorated with a beaded row for added textural interest. They weigh 1.1 grams for the pair and are supplied with butterfly backs to secure their 19mm pins.
