This necklace was Handmade by me.  I wire wrapped the pendant with gold plated square wire.  A natural Dendridic Agate gemstone is the focal stone.  That piece is hung from a beaded Necklace made of a kumihimo seed beaded woven section and a bead strung section, all made by me.  It  measures 23"  The colors of grays and browns both shiny and mat harmonize with the piece.
