Set with a cushion-shaped emerald weighing 12.88 carats, flanked on each side by French-cut diamonds, mounted in platinum.

Colour and Clarity: According to both Gübelin and AGL reports, the emerald is natural, of Colombian origin, with no indication of clarity enhancement. Comment on Gübelin report states that this emerald is virtually free of fissures and fractures. AGL report also gives this emerald an "Exceptional" Total Quality Integration Rating. Please refer to both reports and their respective appendix and book for details. In our opinion, the emerald is of saturated, strong green colour, extremely clean to naked eyes which is very rare quality in natural emerald. Upon 10x loupe, there are only a few very minor and transparent natural inclusions around the corners, but generally clean under loupe check. Diamonds are about H to I colours, VS clarity. Condition: Vintage ring mount shows signs of wear and abrasions to the metal, otherwise in good condition.
