Natural Blue Zircon Ring with 22K Gold. I cast the ring shank from a cuttle bone shell to create the unique and highly textured ring band. I got the blue zircon from a nice crystal from Cambodia. I cut it with one of my favorite high refractive cuts called ‘Gamma Brilliant’. The stone has over 70 individual facet cuts!  Natural Zircon is super special because it has a refractive index higher than diamond. This looks like a blue diamond in a size 7.5 ring.
