Comment: If you are interested in gemmology, study this stone's images. It was cut to show a small axle of violet-blue that sits only in the very tip of the gem. When turned sideways the stone becomes orange yellow! Collectors know this effect, but it is rare to see in such an extreme. This is NOT color zoning but ‘pleochroism’: the stone changes color with the angle of perspective. Nor is this called color change (because the light source does not effect the color). Gemmology geeks aside, this is an impressive natural phenomena. It would deserve a special setting to show the various colors. Such fine points would be lost in heat treatment. Near 3 carat. No window. No visible inclusions. Well cut (obviously the capturing of the violet in the face is a masterstroke). First impression color is sky blue violet, with perhaps some greenish yellow undertones. To me, personally, this is one of the most fascinating sapphires in our stock.
