A set of two carefully paired diamond 14k gold floating rings: a 2.55 ct fancy blue grey brilliant cut diamond, and a .5 ct  white brilliant cut diamond. The blue grey color of this clear cut diamond is attributed to the presence of boron impurities as the diamond is formed in the earth. For more information on diamonds in this color range, here is an in depth article from the Gemological Institute of America. Both rings are size 6.5, can be resized.
