SAPPHIRE AND DIAMOND RING

Centring on a cushion-shaped sapphire weighing 12.18 carats, on a domed mount set with rose- and brilliant-cut diamonds together weighing approximately 2.00 carats, mounted in 18 karat white gold.

Colour and Clarity: According to Gubelin report, the sapphire is natural, of Burmese origin, with no indication of heating. Please refer to the report for details. In our opinion, the sapphire is of intense blue colour, in medium dark tone, with good brilliance. Under 10x loupe, there a few fingerprints close to the crown and two included crystals, but these features are not seen to naked eyes. The diamonds are probably of F to G colours, VS clarity. Condition: In mint condition.
