A PAIR OF UNMOUNTED DIAMONDS
Each brilliant-cut diamond weighing 10.88 and 10.88 carats
Accompanied by two reports nos. 1142070786 and 1132802979 dated 11 October 2011 and 25 January 2012 from the Gemological Institute of America stating that the 10.88 and 10.88 carat diamonds are D colour, flawless clarity, with excellent cut, polish and symmetry
Also accompanied by two supplemental letters from the Gemological Institute of America stating the 10.88 and 10.88 carat diamonds have 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
