Hi to all. I recently purchased this unheated 2.77 ct. cushion cut sapphire. It has a C. Dunaigre cert. that gives a colour/hue as blue and saturation as vivid but no mention of tone. Treatment; no indications of heating. Origin: Shows gemological properties consistent with Sri Lanka (Ceylon). The blue is amazing and the stone just glows. Thoughts on the tone? On this stone? I realize terms like cornflower blue and royal blue are imprecise and loose terms but I wonder if GRS would call this royal blue or where it fits on the blue spectrum?
Regards,
Andy
