Each 9ct yellow gold star in this trio has a clear cubic zirconia crystal centre to help them twinkle like the real thing. Stamped with a 375 metal mark and with a 1cm distance from front to back, the studs are secured in the ear by butterfly backs. Weighing 0.3 grams together as a pair, the star design of these earrings measures 0.3cm x 0.6cm x 0.1cm. A nice treat for yourself or a wonderful Christmas gift.
