Each suspending a pear-shaped diamond weighing 4.20 and 4.01 carats, joined to the line of brilliant-cut diamonds, spaced by a conch pearl measuring approximately 7.9 x 5.5 x 5.4 and 8.0 x 5.6 x 5.3 mm, to the brilliant-cut diamond hook, mounted in 18k white gold, 4.6 cm long
Accompanied by two reports nos. 2125904137 and 5101483436 dated 1 August 2011 and 17 February 2011 from the Gemological Institute of America stating that the 4.20 and 4.01 carat diamonds are D colour, internally flawless clarity
Also accompanied by two supplemental letters from the Gemological Institute of America stating the 4.20 and 4.01 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
