This ring was so popular that we are down to our last two pieces so we have put it on sale. The center round stone measures 7mm (1.3 carats). It is a gorgeous & deeo tanzanite blue color. It has a lower halo border of tiny, round stones which also cover the entire front and sides of this ring. The setting, with its beaded silver edging, gives this a Deco look. Unique and beautiful.
