This appealing Necklace features 2 strands of Sardonyx Agate Rounds. The 10mm Rounds display a range of black, white & gray patterns, with each stone unique. The Rounds are faceted, sparkling in reflected light. We've paired the Sardonyx Agate with 2mm Black Seed Beads, which are placed between each of the larger stones. The Seed Beads add structure to the design and increase the flexibility of the Necklace. At the top of the Necklace the Agate transitions to 4mm Black Czechoslovakian Nailheads, streamlining the silhouette and ensuring a comfortable fit. Czech Nailheads are made from pressed glass and come in a number of difference shapes; our Nailheads are round, with faceted domes on one side and a flat back. Like the Agate, they give off a refined sparkle. The Necklace is finished with Sterling Silver Rounds & Toggle Clasp and adorned with a Southwest Designs Sterling Charm. The piece weighs 98 grams and the 2 Necklace strands are each 21-1/2 inches long.
