This ring is amazing! It is 18K gold electroplate. It has one of the most amazing stones I've seen. The stone is cornflower blue with a cut that I can only describe as a "twisted fan." It is like there are two fan cuts done, but the stone twists in the center so that the ridges go the opposite directions on each end. To hold the stone, the setting splits into two triangles with the stone held in between. I believe the stone is a blue topaz, but I do not know for sure. I bought this at an estate sale, but no one there knew exactly what type of stone this is. Regardless, it is gorgeous and so very unusual! I would keep this myself if it fit me.
This ring is a size 7.5. It is stamped "18KGE" inside the band.
