The Rose Quartz ear jackets with stud earrings are perfect additions to any outfit. The Rose Quartz is 10mm across and I have added a lotus flower charm to the backing so you can wear just the stud earrings with regular backing or add the pretty lotus flower. The lotus flower backing can be worn with other stud earrings to. I just love these. The come in Gold or silver plated stud. Each pair comes in a jewelry box with a gift card and polishing cloth ready for giving.
