A genuine GIA or HRD Antwerp certificate can be verified in seconds, directly on the issuing laboratory's official site. Here's how, and what to look for so you're never misled.
A diamond certificate describes a stone's precise characteristics, weight, colour, clarity, cut, as observed by an independent laboratory. But a certificate alone proves nothing by itself: a document can be forged, mismatched to the stone it accompanies, or simply incorrect. Online verification queries the laboratory's database directly, the only reliable way to confirm a report genuinely exists and matches what you've been shown.
In the trade, the word 'certificate' is commonly used, the technically exact term, used by the laboratories themselves, is 'report' (GIA Diamond Grading Report, HRD Diamond Grading Report). Both refer to the same document.
The result opens directly on your diamond's official record.
HRD requires both the certificate number AND the carat weight, have both ready before clicking.
The result opens directly on your diamond or gemstone's official IGI record.
HRD Antwerp is the diamond grading laboratory of Antwerp, Belgium, the historic hub of the diamond trade. Its reports are widely used in Europe. Every HRD report has a number, which you check online on the laboratory's official website together with the stone's carat weight.
