These attractive inlaid earrings appear to be Zuni Pueblo, but many Navajo create inlaid pieces as well. They are hallmarked "DL." The beautiful bright blue turquoise appears to be from the Kingman, Arizona mine. Each weighs a tenth-of-an-ounce and is 1 and 5/8th's-inches long (and 5/8th-inches wide). They ship with the standard Sterling post clips and a plastic gripper set as well.
