  • Carat

    You can see this

    Carat is weight, not size: 1 carat = 0.2 grams. What carat weight means

  • Certificate

    An independent laboratory report (GIA or IGI for every diamond here) describing the stone's measured characteristics. What a grading report covers

  • Eye-clean

    You can see this

    No inclusions visible to the unaided eye at normal viewing distance. What eye clean means
