These unusual earrings are fashioned into the age-old Navajo naja that is steeped in Dine' history. It is not a horseshoe. Part of the beauty of these particular earrings is the casting technique used. They are certainly sandcast, but they definitely have the appearance of the very, very expensive tufa cast. Tufa cast requires a tufa stone. Kevin Bellah makes it look easy without one. Length is 1.5-inches, and 1.25-inches at the widest point. Weight per earring is 11.6-grams, or .40-ounces.
