This beautiful Necklace was handcrafted using 5.5mm diameter Sterling Silver Rings (about a 1/4-inch outside dimension). There are 518 Rings in total, which are precisely woven into a chain maille pattern known as Byzantine Link. The Byzantine pattern creates a "rolled" Bracelet Chain that is striking in appearance yet extremely comfortable to wear. The Necklace is finished with a 16mm Sterling Silver Spring Ring Clasp, which is both attractive and very secure. The piece is adorned with a Southwest Designs Sterling Silver Charm. The Necklace weighs 66 grams, and is 21 inches in length. This is a go-to, versatile piece that looks great with both casual and dressy attire.
