Joining in the bandwagon of blue sapphires lately. I've been deciding on this stone for a while but finally got it.
It's a 7.03 carats unheated Ceylon Cornflower Blue sapphire with an AIGS lab report.
I took a photo with different lighting conditions and the stone holds great color on all types of light (even in incandescent!). I was really searching for an unheated blue to have more crystal...but the thing about cornflower blues are they are usually heated and included, it is difficult to find an eye clean stone (price would be over the roof as well!). Heating somehow takes away the trasparency and velvet that can both be present in unheated cornflowers. This stone has a fingerprint which is visible is some angles but the color(nice open color) and transparency is difficult to find in unheated blues so I got it.
Here's the stone in natural daylight and under LED lamp:
In direct sunlight together with an almost 5 carat eye clean GRS Pigeon's Blood Unheated Ruby (asking price was a lot and I find the stone dark).
I also compared the stones with other unheated blues. There was another 7 carat GRS blue (not described as royal). It has a nice color in some light but turns dark in some (while the cornflower I got appears almost royal blue in the same light). Also there is a smaller "Deep Royal" which is too dark IMHO and a 4+ carat cushion that appears steely (has a gray modifier)
