Colour and Clarity: According to GRS report, the sugarloaf sapphire is natural, of Burmese origin, with no indication of thermal treatment, of GRS-type "Royal Blue" colour. Please refer to the report for details. In our opinion, the sapphire is of strong blue colour, eye clean.

Diamonds together weighing approximately 0.75 carat, are about F to G colours, VS clarity. Condition: Platinum ring mount, in very good condition.
