CERTIFICATE OF AUTHENTICITY

HANNA Jewelry provides a certificate of authenticity for all of its creations; each one is unique and numbered, proving the origin of your jewel.

HANNA Jewelry also have their own certificate, delivered by gemological laboratories such as the GIA (Gemological Institute of America) and HRD Diamond Certification. This certificate acts as the diamond’s identity card: all of the stone’s characteristics, such as its weight, its cut or its provenance are stated on it.
