100% Solid .925 Sterling Silver. Spring Leaf ear cuff cartilage earrings. Unique handmade jewelry by RingRingRing on Etsy. It is lightly antiqued by oxidizing and polished to show the details of the design. No piercing needed. As can be seen in the photo, the right side ear cuff and left side ear cuff are not exact mirror images, but are close enough in appearance to be worn as a pair.
