Set with a cushion-shaped colour changing sapphire weighing 26.90 carats, within a surround of brilliant-cut diamonds, to a stylised diamond-set basket, the diamonds together weighing approximately 1.20 carats, mounted in 18 karat white gold.
Condition
Colour and Clarity: According to GIA report, the principle colour-changing sapphire is natural, with no indications of heating. Please refer to the report for details. In our opinion, the sapphire has a noticeable colour change, from violetish-blue in daylight to violet in incandescent light, very clean to naked eyes. Under 10x loupe, there are a few fingerprints on pavilion which do not affect the transparency and brilliance of the stone. Diamonds in the surround are probably of F to G colours, VS clarity.
Condition: Simple and fine setting, in mint condition.
