This substantial statement turquoise ring is a real stunner! The Royston Turquoise has a beautiful bluish/greenish tone with large flecks of coffee brown. The stone and backplate measure 1.5" x 1 1/8" and the band is almost .5" in width. Made entirely of .925 sterling silver. Size 6.5 (fits more like a 6-6.25 due to width of the band).
