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.
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.
Have a jeweller in your local area remove the diamond from the ring mounting.
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.
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.
Include a description of the stone, services requested, payment information, return shipping address and insurance information alongside your diamond and client-agreement form.
Ship your diamond using an insured and reliable service, like registered mail.
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.
