IMPORTANT SAPPHIRE AND DIAMOND RING

Centring on a cushion-shaped sapphire weighing 12.60 carats, flanked on each side by a cushion-shaped diamond together weighing approximately 4.00 carats, mounted in platinum. Ring size: 6

Colour and Clarity: According to both Gübelin and AGL reports, the sapphire is natural, of Kashmir origin, with no indication of heating and clarity enhancement. Gübelin appendix states that this sapphire "possesses a richly saturated and homogeneous colour, combined with a high degree of translucency." Please refer to the reports and appendix for details. In our opinion, the sapphire shows a saturated, deep strong vivid blue colour, with good brilliance. Clean to naked eyes. Upon 10x loupe, the sapphire is still quite clean, only a few tiny crystal inclusions and minor growth zoning, but not seen to naked eyes and do not affect the brilliance. Two cushion diamonds weigh approximately 2.00 carats each, about F to G colours, VS clarity. Condition: Platinum ring mount, in mint condition.
