AN UNMOUNTED DIAMOND
An unmounted brilliant-cut diamond weighing 23.76 carats
Accompanied by report no. 1152749844 dated 10 December 2013 from the Gemological Institute of America stating that the 23.76 carat diamond is D colour, flawless clarity, with excellent cut, polish and symmetry
Also accompanied by a supplemental letter from the Gemological Institute of America stating the 23.76 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 I and the 105.60 carat Koh-i-noor, are examples of Type IIa
