A magnificent and important Art Deco ring, dating to circa 1930 and set in 18ct yellow gold with French import marks. The centrepiece is an emerald cut Colombian emerald of 2.56 carats, of fine colour — Colombia being the most prized and historically significant origin for emeralds, producing stones of an unrivalled depth and richness of green. The emerald is of minor oil treatment, the standard and most accepted form of enhancement for emeralds of this quality, and is surrounded by a border of twelve old European cut diamonds of an estimated 2 carats in total, F/G colour and VS2 clarity — stones of exceptional quality whose crisp brilliance provides a luminous frame to the emerald. The combination of an emerald cut Colombian emerald and old European cut diamond cluster is a quintessentially Art Deco composition of the highest order.

A ring of genuine importance — a 2.56-carat Colombian emerald of fine colour with minor oil treatment, set in an Art Deco cluster of 2 carats of F/G VS2 old European cut diamonds, is a combination of origin, quality, and period design that is increasingly rare to encounter at any price.
