Very shiny blue Zircon from Cambodia, 5.03ct Round Cut Natural Blue Zircon from Cambodia. It's hard to find a round blue zircon as they are usually cut in cushion. Also please note that the slightly greenish color in some images are due to reflections from the trees outside, this stone is not greenish but just blue. In another hand, in some pictures the natural dispersion of colors gives some deep blue colors that are not always visible. My personal grading of the color would be between A to B grade. Apologies for the few grains of dust on and around the stone, it is actually perfectly clean and spotless.
