Our certificate of authenticity

Every jewel purchased on the site is accompanied by a certificate of guarantee and authenticity reporting all the characteristics of the product manufactured in our laboratories.

For jewels set with diamonds of 0.30 carat or more, Diamoro uses diamonds certified by international gemmological institutes.

In this case, in addition to the guarantee and authenticity certificate, the customer will also receive the gemmological certificate of the set diamonds.

GIA - Gemological Institute of America

IGI - International Gemological Institute

HRD - Hoge Raad voor Diamant

GIA, IGI and HRD are internationally gemmological institutes, recommended by experts for their professional competence and seriousness.

The customer can customise the jewel asking for non-certified diamonds, even if their weight is 0.30 ct or more.

In this option the jewel will have a lower final price. For some jewels in the online catalogue there is already a cheaper version.

Please note

The jewels set with certified diamonds are easily recognizable on the site because the acronym of the gemmological institute used is mentioned in the name and in the product fiche.
