EMERALD AND DIAMOND RING

Centring on a step-cut emerald weighing 13.06 carats, surrounded by brilliant-cut diamonds together weighing approximately 4.05 carats, mounted in platinum and 18 karat yellow gold.

Colour and Clarity: According to Gübelin report, the emerald is natural, of Colombian origin, with indication of minor clarity enchancement. Please refer to the report for details. In our opinion, the emerald is of medium, bright green colour, considered eye-clean for emerald standards. Upon 10x loupe, there are some natural inclusions, one dark, one minor surface-reaching inclusion, cavity on a corner, and a few nicks along girdle and facet corners, which are not noticeable to naked eyes and very common to natural emerald. Diamonds in the surround are about G to H colours, VVS2 to VS clarity, good brilliance. Condition: Minor signs of wear, otherwise in very good condition.
