These earrings are made with 22 ga copper wire weaved into the European 4-in-1 style. The wire used for the weave, pearl attachments and earwires is all copper. The pearls are freshwater pearls, dyed to a coppery bronze color. The earrings dangle about 2 1/2 inches long from top of earwire to bottom of pearls. Linda has created the chainmaille and Robert has done the earwires and pearl attachments.
