This piece varies from top right to bottom left as the small clasts transition from fully intact to fully melted into the mass.  This gives a pleasing transition and a nice balance to the pendant.  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, is included. It is tarnish resistant silver, not plated, and does not contain any nickel so it is hypoallergenic. I can make this chain in any length.
