‘In the gemstone industry, as in most other luxury markets, the rarity of an object directly correlates with its desirability. For perspective on the rarity of the 102.39ct Oval Brilliant in the diamond market, consider this statistic: less than one-half of one percent of all stones over one carat submitted to GIA annually are D, Internally Flawless, or D, Flawless. It is rare for any diamond to possess D-color and Flawless clarity, let alone one of 102.39 carats...The 102.39ct Oval brilliant diamond’s stunning appearance cannot be attributed to nature alone. Transforming bulky rough into a graceful, glittering gem is indeed an exacting art, requiring experience, vision, and a tremendous amount of patience. In this regard, the 102.39ct Oval Brilliant diamond is as much a work of human ingenuity as it is of nature. Its spectacular fashioning has coaxed the best out of this massive gem, which consequently displays the finest color and clarity.’


Excerpt from the GIA Monograph


‘However, the 102.39 carat oval brilliant…is special based on its combined characteristics. Research done by GIA scientists over the last several years found that large diamonds such as the 102.39 carat oval brilliant likely formed in the lower mantle of the earth…This diamond likely was formed at depths of four or five times deeper than what has been believed for decades, adding to its legacy.’
