A DIAMOND AND WHITE OPAL RING
Centering upon a shield-shaped rose-cut diamond weighing approximately 5.36 carats, overlapping a triangular-shaped white opal, joined by circular and oval-shaped rose-cut diamond openwork prongs with brilliant-cut diamond trim, mounted in 18k white gold, ring size 6
Accompanied by report no. 14731189 dated from the 22 September 2010 Gemological Institute of America stating that the 5.36 carat diamond is D colour, internally flawless clarity
Also accompanied by a supplemental letter from the Gemological Institute of America stating the 5.36 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
