The Kodiak Classic Sea Glass Earring is the original Cyn Elizabeth Studios earring. It consists of matched sea glass found in Alaska, paired with a freshwater pearl. Sea glass is in a solder setting. Earring hooks are 925 sterling silver, hypoallergenic and nickel free. Units consist of a variety of colors of sea glass and pearls. Please note, I ONLY use genuine Alaskan sea glass for all of my jewelry. No two pieces are the same size and shape. Earrings are matched by closest color and then shape.
