Accompanied by report no. 10593341 dated 10 March 2014 from the GIA Gemmological Institute of America stating that the 9.17 carat diamond is Fancy Intense Pink colour, SI1 clarity, a Diamond Type Classification letter stating that the diamond is Type IIa, and a letter from the GIA.
Note: It is common nowadays for coloured diamond cutting styles to be modified in order to better collect and intensify the colour appearance. Achieving the strongest colour appearance in standard brilliant cuts can be challenging, as it can mask or soften the colour. Mixing the best proportions while keeping the standard brilliant cut style is difficult, unless the inherent colour of the diamond is strong and the rough has lent itself to just the right proportion possibilities. This rare combination of shape, cut and proportion set can be found in this unique old diamond, resulting in a rare pear brilliant-cut diamond of Fancy Intense Pink colour. The fact that this Fancy Intense Pink diamond weighs 9.17 carats adds to his rarity. A true treasure of Nature.
