Every London Antwerp Diamonds diamond we sell comes with a certificate that guarantees and documents the quality of your diamond. Without this certificate, you have no proof of the value of your diamond.

A certified gemologist prepares the diamond certificate (also called a grading report, dossier or quality report). The gemologist scrutinizes the diamond under a microscope, noting its dimensions, clarity, cut, colour, finish, symmetry and other characteristics.

The most highly valued diamonds in the industry come with a diamond certificate report from the Diamond High Council (HRD) or the International Gemological Institute (IGI), known and respected for having the most strict, consistent and unbiased systems for grading diamonds in the world. That's why every loose diamond we sell at London Antwerp Diamonds has been analyzed and graded by either the HRD or the IGI. A certificate from HRD or IGI guarantees forever the quality of your London Antwerp Diamonds diamond.

Be aware that if you buy a diamond without a certificate, you are trusting the salesperson's claim as to its quality. A trained gemologist or even another jeweler may disagree with that salesperson's assessment. Protect yourself: get a grading report.

Please note that a 'certificate' and an 'appraisal' are two different things. A certificate guarantees your diamond's quality. An appraisal places a monetary value on your gem. Of course, a certificate from HRD or IGI greatly facilitates appraisal of your London Antwerp Diamonds diamond.
