This necklace is really three separate pieces that you can layer however you wish...as each strand has its own clasp. The pendant featured is a beautiful green amethyst set in a bezel setting on a double rollo chain. The other two necklaces featured are a hammered link chain and a rollo style chain with quatra links that are wire wrapped with green amethys beads. They all have adjustable links of up to 2". If you have any questions please feel free to e-mail me! all sterling silver.
