This is an 18 inch (jump ring at 16 inches) custom piece made for me by Whiteflash. The center stone is a 3.08 carat blue spinel. The halo is made up of 26 x 1.35mm ACA diamonds, and the chain has two each 8 point 10 point and 15 point stones set into the chain. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
