Argentium Hammered Hoop Earrings. These earrings are handmade of Argentium Sterling Silver for a shine that will last longer than traditional Sterling Silver. Argentium Silver is 93.5% pure silver as opposed to 92.5% of standard Sterling Silver. A touch of Germanium keeps them shiny longer. Shaped, hammered, and polished. The hoops are 16 gauge, thin enough to be very light, but tumble hardened to remain durable. Hypoallergenic Niobium French hooks or 316L Surgical Steel Leverbacks. Available in 1.5" and 2.0" Diameters. Includes polishing cloth for all jewelry. Shipped in gift box.
