Diamond certification can provide you with an accurate assessment of the quality and value of your diamond ring. A diamond certificate is a sort of grade card for the stone, including ratings of its cut, clarity, colour and carat weight. An appraisal will provide a market value for your diamond ring, but only certification can create an official record of the stone's quality. Certification requires more than just a visit to your local jeweller.

  1. 1

    Contact the Gemological Institute of America, the most respected authority on gems, about current pricing for a diamond certification. Choose the closest GIA laboratory for your diamond certification.

  2. 2

    Have a jeweller in your local area remove the diamond from the ring mounting.

  3. 3

    Safely package your diamond or have your jeweller package it for you. Secure the diamond in unlabeled parcel packaging per the preferences of the Gemological Institute of America.

  4. 4

    Print and fill out the GIA client-agreement form. Include this form in your package when you ship your diamond to the GIA lab in New York or California.

  5. 5

    Include a description of the stone, services requested, payment information, return shipping address and insurance information alongside your diamond and client-agreement form.

  6. 6

    Ship your diamond using an insured and reliable service, like registered mail.

Tips and warnings

  • Set diamonds can be appraised and assessed for colour, but not certified. If you just need a value for insurance purposes, opt for an appraisal with a trained and GIA certified gemologist.
  • Be sure to adequately insure your diamond when shipping it for certification.
