The GIA certificate

Piaget GIA certificate

The GIA (Gemological Institute of America) is an independent international certification body established in 1931. It assesses the quality of stones impartially and according to precise criteria known as the 4Cs.

Piaget pledges to issue a gemological certificate for each of its center diamonds over 0.2 carats, providing a veritable guarantee that they score highly against the 4 criteria defined by the GIA.
