Pink diamond is a type of diamond which has all the same elements as more commonly known diamonds except that they also exhibit pink color. The source of their pink color is greatly debated in the gemological world but it is most commonly attributed to enormous additional pressure that these diamonds undergo during their formation. ^[2]Pink diamonds belong to a subcategory of diamonds called fancy color diamonds, the generic name for all diamonds that exhibit any sort of color. ^[2] Pink diamonds range from Flawless to Included, just like white diamonds. Several pink diamonds with internally flawless clarity have been discovered, but only one is known to be completely flawless, the Pink Star(which was shortly renamed the Pink Dream until it diverted to Sotheby’s).
