A grading report is a documentation of a careful examination of the stone by qualified professionals.
Regardless of which lab it comes from, the report will note the stone’s shape, overall measurements, and carat weight.
It will also note any inclusions and will assign a clarity grade and a color grade.
Not all diamonds come with grading reports, and you should not conclude that the absence of a report means that there’s anything wrong with the stone. Many beautiful stones are sold without reports.
With or without a report, ask your jeweler to explain how cut, clarity and color contribute to a stone’s value.
