Colour and Clarity: According to GRS report, the sapphire is natural, of Burmese origin, with no indication of thermal treatment. Please refer to the report for details. In our opinion, the sapphire is of strong blue colour, lively and eye clean. Upon 10x loupe, there are some fine rutile needles, not seen to naked eyes. Diamonds are about F to H colours, VS clarity.
