What You Should Know About Diamond Certifications

All Jared loose diamonds, as well as some diamonds already set into jewelry, have been graded by an independent lab before making their appearance in store. The report from that evaluation is called a diamond certificate - also known as a diamond grading report, diamond dossier, diamond quality document or diamond light performance certificate.

This document gives you important information that can help you to make an informed diamond purchase.

Your independent diamond certification is produced by trained professionals and will include the following information:

  • The 4C's of diamond quality: the color, clarity, cut and carat weight of a specific diamond as viewed under magnification.
  • A diamond's characteristics: proportions, finish, and treatments.

Depending upon the diamond, you may also receive a light performance certificate:
  • Light performance measures the bright white light (brilliance), bright color light (fire) and scintillation (sparkle) of a diamond.

Because no two diamonds are exactly alike, a diamond certificate can even serve as your diamond's fingerprint or identification in case of loss or theft.
