My earrings are made from maple wood and I paint them with iridescent acrylic paints.This pair of earrings has a tree design on it. The background wood is stained a dark brown and painted on top is a shimmery gold trunk with shimmery green leaves. The ear hooks and jump rings are made from gold plated surgical steel so you will not get any allergies!!!The approximate diameter of the wood is 4.5 cm.
