Colour and Clarity: According to both Gübelin and SSEF reports, the sapphire is natural, of Burmese origin, with no indications of heating. Please refer to the reports for details. In our opinion, the sapphire is of strong blue colour, eye clean and lively. Upon 10x loupe, there are only some minute silks and fingerprint inclusions, not noticeable. One tiny opening on lower girdle, close to a prong, not noticeable to naked eyes. Two half-moon diamonds are about H to I colours, SI clarity. Other round diamonds are probably of G to H colours, VS clarity. Condition: Platinum ring mount, with size guard, of eternity setting that ring shank cannot be re-sized and currently is American size 6.5. Overall in very good condition.
