These ear cuffs are made with copper core wire, you can choose the material with which the wire will be plated on, and it also beads from the semiprecious stone. They are sold as a pair and also you can buy one ear. Each cuff measures about 3 1/2 inches in length from tip to bottom and about 1 1/2 inches in width from the largest point of the curve to the inner point. These measurements will vary slightly because they are handmade, but they will never be overly large or too small. Each of these ear cuffs will be slightly different. If they don't fit perfectly, just carefully bend them to the shape of your ear. They are very cooperative. If you want to make your own changes of ear cuffs or tiaras, or maybe you have some ideas of design for your jewelry, you can always write to me. Thank you for coming to my shop ❤
