A DIAMOND RING, BY CARTIER
Set with a rectangular-cut diamond, weighing approximately 20.43 carats, to the baguette-cut diamond shoulders, mounted in platinum, circa 1940, with French assay mark, in the original Cartier red leather box, accompanied by the original invoice from Cartier dated 29 February 1940
Signed Monture Cartier
With report 13428142 dated 26 July 2011 from the Gemological Institute of America stating that the diamond is D color, VS1 clarity; accompanied by a working diagram indicating that the clarity may be improvable
Accompanied by a supplemental letter stating that the diamond has been determined to be a Type IIa diamond. Type IIa diamonds are the most chemically pure type of diamond and often have exceptional optical transparency. Type IIa diamonds were first identified as originating from India (particularly from the Golconda region) but have since been recovered in all major diamond-producing regions of the world. Among famous gem diamonds, the 530.20 carat Cullinan and the 105.60 carat Koh-i-noor, are examples of Type IIa
