The Wave Swirl Earrings are all sterling silver. The pattern is embossed into the metal in a raised pattern of a stylized wave. The metal is shiny with a high polish. They are very unusual and comfortable to wear. I like to make jewelry that reminds me of the ocean which is constantly swirling and changing shape. These earrings are inspired by the Hawaiian Pacific Ocean which is an everchanging dynamic of life here in the islands.
