The gray clasts scattered on one side of the dark melt in an angular slice set on a square mounting give this piece the feeling of abstract art.  The mounting is a high polished silver. 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 diameter, is included.  I can make this chain in any length.
