Centring on a cushion-shaped sapphire weighing 38.88 carats, within an openwork bombé surround set with marquise-shaped and circular-cut diamonds, to the diamond-set hoop, the diamonds together weighing approximately 8.00 carats, mounted in 18 karat white gold. Ring size:5¾

Colour and Clarity: According to the AGL and Gübelin reports, the sapphire is natural, of Burmese (Myanmar) origin, with no indications of heating, and the colour variety may also be called "royal blue" in the trade. AGL appendix further stated that the sapphire is from Mogok valley in Burma. Please refer to the reports for details. In our opinion, the sapphire is of medium saturated blue colour with slight violetish tint, very good brilliance and very clean stone. Under the 10x loupe inspection, the sapphire has minor fingerprint and silk inclusions at the side of the stone, but not noticeable to the naked eyes. The marquise-shaped diamonds are mainly about G to H colour (with a few F and I colour) and the circular-cut diamonds are about H to I colour, majority are about VVS to VS clarity (some circular-cut diamonds are SI clarity). Condition: Karat white gold ring mount, overall in mint condition.
