RJ436 - Celtic Horse Brooch - Solid Pewter. The actual disc is 1 and ½ inches. This Celtic disc brooch was hand cast in solid, lead free, jeweler's pewter. Inspired by the Pictish carvings of horses in Inverurie, Scotland, this is a timeless classic. The design was taken from Bain and is a wonderful Celtic, zoomorphic, horse design. The findings are hand soldered and a loop on the back converts this pin to a pendant. Just add your leather cord or chain. This brooch is slightly domed and highly detailed. The actual disc is 1 and ½ inches.
