Diamond Buying GuideDiamond Certification
When purchasing a loose diamond you should expect to see a copy of its certificate, provided by an independent third party laboratory. A diamond certificate, also called a diamond grading report, a diamond dossier, or a diamond quality document, proves that your diamond has gone through a thorough and unbiased professional examination. A diamond grading report will evaluate a diamond on many different components including:
- Shape and Cutting Style
- Measurement: The diamond’s dimensions measured in millimeters.
- Weight: Weight of the diamond listed to the nearest hundredth of a carat.
- Depth: Depth (for round diamonds) and/or width (for fancy shapes) relative to the diamond’s diameter.
- Table: Table facet (for round diamonds) and/or width facet (for fancy shapes) relative to the diamond’s diameter.
- Cutlet: Appearance of cutlet facet.
- Finish: grades of symmetry and polish.
- Clarity: Clarity grade determined under 10 x magnification
- Clarity Plot: A map of the approximate size, type, and position of inclusion as viewed under a microscope.
- Color: Grade of color.
- Fluorescence: Color and strength of color when a diamond is viewed under UV light.
- Comments: Additional comments on the diamond’s characteristics not mentioned in the report.
