Cornflower blue Ceylon sapphire of 4,98 ct. with no indication of thermal treatment. Modified brilliant/step cushion with rounded edges. Ceylon origin mentioned in the GRS report. When looked from the table position while moving, lighter areas appear. It is in fact the light which is reflected on clouds of very fine rutile needles. These clouds lead to a great softness in the stone. It is velvety, precious and refined.
GRS report nr. GRS2019-019758 of January 14, 2019.
Dimensions : 10,38 x 9,42 x 5,09 mm.

Expert notes:
The arrangement of rutile is splendid, stripes are perfectly designed. We notice in the stone rare small sticks aligned in a parallel way, which reflects that crystals associated themselves and repeated their pattern therefore creating an element of slices. This is rare in a sapphire this beautiful. The magnifying glass x10 is enough in itself to admire the natural non-modified traces in the gem.
