A COLORED DIAMOND RING
Set with a round brilliant-cut fancy intense blue diamond, weighing approximately 1.74 carats, to the plain platinum hoop, ring size 6
Accompanied by report no. 5171282289 dated 24 September 2015 from the GIA Gemological Institute of America stating that the diamond is fancy intense blue, natural color, VVS1 clarity; accompanied by a working diagram indicating that the clarity of the diamond is potentially Internally Flawless
With a supplemental letter from the Gemological Institute of America stating that the diamond has been determined to be a Type IIb diamond. Type IIb diamonds are very rare in nature and contains small amounts of boron that can give rise to a blue or gray coloration. An unusual property of type IIb diamonds is that they are semi-conductors and conduct electricity. Historically, the ancient mines of India produced occasional blue diamonds but today the most significant source is limited to the Cullinan (formerly Premier) Mine in South Africa. Among famous gem diamonds, the 70.21 carat Idol’s Eye and the 45.52 carat Hope are examples of type IIb
