Accompanied by report no. 12956371 dated 23 July 2009 from the Gemological Institute of America stating that the 5.00 carat diamond is fancy vivid pink, natural colour, VS1 clarity; with a working diagram indicating that the clarity is potentially flawless
Also accompanied by a supplemental letter from the Gemological Institute of America stating the 5.00 carat diamond has been determined to be a type IIa pink diamond. Type IIa pink diamonds are very rare in nature, often have relatively few inclusions and are noted for their mostly homogenous colour in the rough. Unlike many other coloured diamonds, the colour in pink diamonds can not only be caused by impurities, but it may also be a result of the diamond's exposure to heat and pressure during transportation into the earth's crust. Type IIa pinks have been found in a number of mining regions around the world. Historically they were found in India (particularly from the Golconda region) and, in more recent times, most notably from Brazil and Africa.
Among famous gem diamonds, the 70.39 carat Empress Rose and the 28.15 carat Agra are examples of type IIa pinks
