This freeform rose cut grey moonstone measures 10mm x 12mm, bezel set in a solid 9ct white gold mount on a 1.6mm halo shank. The white gold hasn't been rhodium plated so is a lovely warm white colour. The moonstone is a good opaque grey displaying a lovely white sheen when rotated. 
This ring can be sized to most finger sizes, please get in touch if you'd like a complimentary ring gauge.
