The creative use of the Hopi’s perfected overlay techniques gives each Hopi belt buckle a unique look and feel. If you're looking for a buckle with a southwestern style in sterling silver make sure you look at some handmade buckles made by Hopi Silversmiths. The majority of the belt buckles created by the Hopi use the overlay technique mentioned and are handcrafted into amazing designs like an eagle, bear claw, horse and rider, and many more. Typically the Hopi Silversmiths use .925 Sterling Silver so you normally don't need to worry about quality when purchasing an authentic Hopi Belt Buckle.
