This 10.06-carat natural fancy blue diamond is one of the world’s rarest natural gemstones. The sky blue radiant-cut jewel is certified by the Gemological Institute of America (GIA) as being a natural fancy blue diamond with almost flawless VVS1 clarity. It is also certified as being a rare Type IIb diamond. This means that it contains no nitrogen, and therefore displays outstanding brilliance. The result is a highly important stone of monumental size, significance, and beauty. Joined by two fancy intense pink diamonds weighing 0.71 total carat and 60 round white diamonds totaling 0.93 carat, this natural gem is the finest blue diamond on the market today. All gems are set in platinum.
