the purer a diamond the more brilliant

The greater a diamond’s clarity, the more brilliant, valuable and rare it is – and the higher it is on the Diamond Quality Pyramid. Virtually all natural diamonds contain identifying characteristics, yet many are invisible to the naked eye. Under the scrutiny of a jeweler’s 10x-magnifying loupe or microscope, natural phenomena – called inclusions – may be seen. These are nature’s birthmarks, and they may look like tiny crystals, clouds or feathers.

Diamonds categorized as internally flawless reveal no such inclusions. Flawless stones are at the peak of the Diamond Quality Pyramid and are treasured for their rarity and beauty. Diamonds with every, very small inclusions are graded as VVS,1 or VVS2. The larger the inclusion, the lower the grade and the less rare the diamond. Inclusions that can be seen with the naked eye are graded I1 to I3.

The number, color, type, size and position of surface and internal birthmarks affect a diamond’s value. Major inclusions can interfere with the path of light that travels through a diamond, diminishing its brilliance and sparkle and therefore its value.
