Proof
Certificates
Certified diamonds carry an independent laboratory report. Natural diamond and lab-grown diamond are labelled separately. AVA confirms the report before production.
Enter the report number printed on the certificate you receive. We open the laboratory’s public lookup in a new tab — AVA does not host, store, or alter laboratory reports.
Stone type is written in full on every commission: natural diamond, lab-grown diamond, or otherwise named. The certificate remains with the piece when it leaves the house.
Note. AVA does not alter laboratory reports. Look up the number on the certificate you receive. For another laboratory, use the verify page printed on that report.
Independent laboratory reports prevail over marketing copy. Stone origin is labelled in full. Clients may seek independent estimates before committing. Legal
