ELKA 12Kt Gold Filled Herringbone Chain Necklace

A shiny and soft gold color, this 16-inch Herringbone chain is 1/16 inch wide. There is a ring clasp, and a tag marked ELKA 1/20 12KT, so it is Gold Filled. Gold Filled is better quality with more gold content (covering) than gold plate. I cannot find out anything about the ELKA Hallmark - so perhaps it is European. NG-105
