Diamond and enamel ring, David Webb

Set with an emerald-cut diamond weighing 8.27 carats, framed by 14 round diamonds weighing 2.60 carats, within a raised mounting of platinum and 18 karat gold applied with opaque black enamel, size 8, signed Webb. 

Good condition with nicking to the underside of the shank. There is a shallow chip to the enamel measuring 6.8 x 3.1 mm to one corner, exposing a pin point-sized section of gold mounting (not readily apparent). The emerald-cut damond is approximately L-M color, VS clarity; minute abrading to the facet junctions. The remaining diamonds are approximately G-H color, VS-SI clarity. The weights are exact and from an insurance appraisal provided by Webb in 1980.
