Colour and Clarity: According to Gübelin and AGL reports, the sapphire is natural, of Burmese origin, with no indications of thermal and clarity treatment. Two cushion diamonds, according to GIA reports, are matching, of G colour, SI1 clarity. Please refer to the reports for details. In our opinion, the sapphire is of very rich blue colour, eye clean. Upon 10x loupe, there are some minor silks and fingerprint inclusions, not seen to naked eyes. Condition: Platinum ring mount, in very good condition.
