19mm Pendant is Amethyst, Blue Topaz, Peridot, and Garnet Set in 925 Sterling Silver and Gold over sterling. 1mm Chain is 925 Sterling Silver with Gold Overlay. Got the chain at JTV, but dont think the pendant from there. The Chain is a sliding adjustable up to 24" from as short as 15 or 16". Everyone needs one of these in their jewelry collection😁. if you want these split out, they would be 40/ea. just comment to me and I will do a new listing And send offer. I took a new picture as the other did not do this lovely pendant justice. NWOT
