Description
- colour-changing sapphire, diamond, white gold
Centring on a cushion-shaped colour-changing sapphire weighing 14.05 carats, surrounded by oval and brilliant-cut diamonds together weighing approximately 2.00 carats, mounted in 18 karat white gold. Ring size: 6
Condition
Colour and Clarity: According to GRS report, the colour-changing sapphire is natural, with no indication of thermal treatment. Please refer to the report for details. In our opinion, the sapphire shows a noticeable colour-change effect, from purple hue in incandescent light, to blue colour under daylight; eye clean and lively. Upon 10x loupe, there are needles and some minor feather inclusions, but not seen to naked eyes. Diamonds in the surround are about F to G colours, VS clarity.
Condition: Kara white gold ring mount, in very good condition.
