Pink diamond is a type of diamond that has 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.
Pink diamonds belong to a subcategory of diamonds called fancy color diamonds, the generic name for all diamonds that exhibit any sort of color. Pink diamonds range from flawless to included, just as do white diamonds. Several pink diamonds with internally flawless clarity have been discovered, but only one is known to be completely flawless.
All Pink diamonds are examined under a loupe to determine their clarity. This 10x magnification determines whether or not the diamond exhibits inclusions either on its surface or inside. Like all diamonds, pink diamond clarity is measured on a scale from Flawless to Included. Only 7% of pink diamonds are either Flawless or Internally Flawless (IF), and majority are Slightly Included (SI). Like most of the colors of fancy color diamonds, the clarity has little effect on a pink diamond’s value. Since pink diamonds are formed by a deformation on their lattice structure, their probability of a low clarity grade is higher, making high clarity pink diamonds extremely rare (<7%).
