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.
