Moss Agate & Brass Crescent NecklaceA deep green moss agate stone is highlighted by swirls of delicate brass wire and a thick, braided wire border. The total length of the necklace is 20" including the pendant and a 3" chain extender. The crescent is 1 1 8" wide. Jeweler's brass is a durable and less expensive alternative to gold. Its strength makes it a great option for jewelry while also lasting through years of daily wear.
