Moss agate silver necklace and pendant. A moss agate and silver bead necklace with a moss agate pendant in a sterling silver prong setting. This is a lightweight handcrafted necklace that’s easy to wear for day or evening. The necklace is 19 inches long and closes with a lobster claw catch. The necklace length can be adjusted a bit by hooking the lobster claw into the sterling silver chain. This is a lovely gift for someone special, too.
