These solid fine silver half-ammonite stud earrings have been created from an original fossil ammonite found by me o the beach in Charmouth, Dorset. They have been made from a mould of the original using silver metal clay, which when fired (I use a blow torch) creates solid fine silver pieces. The rear of the stud is flat polished silver. They have been left with a matt finish, but can be given a high shine if requested (just drop me a message when you order).. Measuring approx. 1cm in diameter these simple studs are big enough to make a statement, and still lightweight and easy to wear.
