A superb diamond ring
Footnotes
Accompanied by GIA report # 11112333, dated August 31, 2016, stating the diamond as: D color, Internally Flawless clarity.
Accompanied by a diamond type classification report, dated August 31, 2016, stating the 16.90 carats diamond is a Type IIa diamond.
By definition, rare is distinctive in its superlative nature; something of unusual quality, merit or appeal. This distinctive stone embodies rarity according to every criterion by which a diamond is measured: color, cut, clarity and transparency.
This diamond has been awarded the highest color grade of D – also known as colorless or exceptional white – and possesses internally flawless clarity. Only the skill of a master diamond cutter can produce a stone devoid of inclusions which also possesses excellent polish and symmetry.
In addition to this rare combination of features, the diamond is also a Type IIa, a characteristic which defines it as almost pure carbon. Type IIa diamonds make up less than 2% of all natural diamonds and are so exceptional because they contain very little nitrogen, or none at all. This means that light can easily pass through the diamond and bounce back to the beholder's eye, producing a stunning, colorless appearance.
Many of the most famous diamonds throughout history have been Type IIa: the world's largest cut diamond – the Cullinan, the Koh-i-Noor and the Hope Diamond are, but few, examples.
