Wiith white, gray, round, long, and angular clasts this sweet little piece has it all!  The background has a blackened, pebbled finish.  This is from a slice of NWA 13119 and is set in a hypoallergenic, tarnish resistant sterling silver with a pure silver bezel.  A 20 inch heavy weight sterling silver rounded box chain, 1.8mm, is included.  I can make this chain in any length.
