In the 1.01ct Fancy Purplish Pink Heart Modified Brilliant, the passion sparked by diamond is enhanced by a rare pink color. Though all diamonds hold significance, rarity is the trait that distinguishes a special diamond from an extraordinary diamond. Gem connoisseurs often refer of a discovery of colored diamond as a "one in ten thousand" event.
This statement is quite telling, for out of all diamonds annually submitted to GIA, no more than 3% are colored diamonds; of these colored diamonds, less than 5% are predominantly pink.
Type II diamonds are rare. They contain no IR-detectable nitrogen in their chemical structure, and represent less than 2% of all diamonds mined. Not coincidentally, they also tend to display exceptional transparency. Type II diamonds are also subdivided into two groups. Type IIa stones have virtually no atomic level substitutions; Type IIb diamonds contain a small amount of boron that substitutes for carbon at the atomic level. According to the records of the GIA laboratory, the 1.01ct heart modified brilliant-cut diamond described in GIA Colored Diamond Grading Report #1126691921 is type IIa.
