18ct Gold Cushion 5,55ct Sapphire and Diamond Three-stone ring

This long cushion cut Blue Sapphire is of natural Ceylon origin. To perfect aesthetics, it has been enhanced by a process of re-cyrstallisation diffusion. The process is permanent and the properties of a sapphire remain unchanged. Set between two round cut diamonds in white, 3-claw settings and fitted to a tapered shank, contrasting warm tones of 18ct yellow gold.
