AN IMPORTANT DIAMOND PENDENT NECKLACE
The cushion-shaped diamond weighing 20.39 carats, surmounted by a pear-shaped diamond weighing 0.90 carat, joined to the collet-set diamond double-strand necklace, mounted in 18k white gold, 40.3 cm long
Accompanied by report no. 2155100703 dated 19 November 2012 from the Gemological Institute of America stating that the 20.39 carat diamond is D colour, flawless clarity, with excellent polish and symmetry
Also accompanied by a supplemental letter from the Gemological Institute of America stating the 20.39 carat diamond has been determined to be type IIa. 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
Report no. 2148644814 dated 12 July 2013 from the Gemological Institute of America stating that the 0.90 carat diamond is D colour, VVS2 clarity
