The Celtic Land Collection by Sea Gems is a collection of fine Celtic Enamel gifts inspired by the Celts' love of colour and design. Early vitreous relics date back to 13BC. The items are hand made: the design is stamped on copper, the raised portion forming a network of cells, into which glass like vitreous enamel is painstakingly applied, then fired to 760C, ground - polished and plated with 22crt gold. Followed by a final polish to reveal the vibrant colours that typify Celtic art
