All Sellis of Cambridge earrings are hand-made in my workshop in Cambridgeshire. The only materials used are Sterling Silver and/or 9 carat/18 carat Gold. Generally, the ear fittings for drop earrings are ear hooks . However, you may request a butterfly and post fitting. All stud earrings have a butterfly fitting. Most earrings have a matching necklace or pendant in a similar design to complete the perfect look.
