A perfectly formed pewter ammonite fossil necklace on a Sterling silver chain. The ammonite pendant is 3.2 cm (1.3") high. On an 18 inch Sterling silver belcher chain. Each ammonite necklace is packaged in a black presentation box and an organza pouch. All Glover and Smith necklaces are handmade from solid, polished lead-free pewter which is non-tarnishing (that was the lead in old pewter) and are guaranteed nickel-free and allergen friendly. We use Sterling silver chains and jump rings for their strength. Because we use solid metal the surface of your fossil necklace will never flake like a silver plated necklace. To clean just wash with warm soapy water and occasionally use a silver cloth on the silver components. All Glover and Smith pewter jewellery designs are handmade exclusively by us in Salisbury, Wiltshire, UK.
