Incredible artist design MOKUME GANE.  This Japanese art technique dates back to 17th century and was used on Samurai Swords…..very rare design on hoop earrings.  More common on wedding rings.  Truly an investment into a special art.  Rare…when they are gone, there is no more.  Sterling Silver with copper metal overlay design.  Look it up…not easy to do. Overall length is 2″.
