Genealogy Round Brass Family Tree Earring with amber bead. Another great family tree earring! These earrings are brass and have been hand made in Portland, Oregon and no two are alike. Earwires are 14 karat gold filled and all materials have been treated with a tarnish resistant clear coat to keep its beauty. These also have a small amber bead added for decoration. Dark background really makes this tree pop! Measurements: (without earwire) 3/4" round.
