The marquise-shaped diamond of fancy intense yellow color weighing 3.08 carats, framed by calibré-cut sapphires in a frame of conforming shape set with small round, single-cut and baguette diamonds weighing approximately 1.00 carat, mounted in platinum, size 5¾, signed Birks-Ellis. 

Good condition with minimal wear to the mounting; evidence of sizing. Please see GIA report no. 17243612 stating that the marquise diamond is Fancy Intense Yellow, Natural Color, SI1 clarity. The sapphires are a nicely-matched medium-deep blue and of good clarity. One or two of the sapphires may be synthetic (not unusual for small accent stones found in mountings dating from this period). The smaller diamonds are approximately G-I color, VS clarity.
