This quirky pair of sterling silver stud earrings have a sci-fi style, crescent moon shape with a faux opal crystal set at its centre. The cloudy, round cut stone measures 4mm and is held in a triad of claws. The wire crescent measures 7mm high and appears to float as it is attached solely to the claw setting. Don't let them float away though! You can secure them firmly with their butterfly backs.
