Outstanding size, color, clarity and cut make this extraordinary 12.11-carat pear-cut white diamond one of the finest on the market. This stone is certified by the Gemological Institute of America and Gubelin as being Internally Flawless, D color and Type IIa, meaning it contains no trace of nitrogen, the element that gives diamonds color. This lack of nitrogen makes the extraordinary stone a full two shades whiter than the whitest diamonds. A letter from the GIA accompanies the certificate that states, “Type IIa diamonds are the most chemically pure type of diamond and have exceptional optical transparency,” underscoring this gem’s visual beauty.

Further exemplifying the diamond's rarity is the inclusion of a coveted Appendix Letter from Gubelin that states: "While some Type IIa diamonds can be tinted pink or brown, others are blessed with the most exceptional and pure colour and are often associated with a high degree of transparency, a quality sometimes referred to as 'water.' [...] This diamond of 12.11 ct combines such exceptional characteristics as to display this particular quality of the finest 'water.'" The letter also notes, "Additionally, this diamond has been cut and polished following traditional faceting techniques which were used over a century ago to produce an antique-looking stone. [...] Diamonds of this kind and size, exhibiting a superior quality as well as an old cutting style, and belonging to the finest natural colour type IIa diamonds are very rare."
