A ring in the Retro style of the 1940s, beautifully semi-invisibly set with Colombian emeralds of fine colour and clarity, with tiny diamond points in between, a style favoured by Cartier, in a wide 18 yellow shank, tapering towards the back. The widest part of the ring at the front is 15mm, and the finger size UK N 1/2, US 7- sizeable within moderation. Great skill in cutting and setting is needed for a ring of this type.. It is difficult to photgraph emerald successfully, but the emeralds in this ring are really the best.
