Certification

Being a reliable company in the eyes of our clients is, for us, the basic building block of Mart Diamonds brand. To achieve the highest standard of diamond quality appraisal, we’re cooperating with the most esteemed certification labs around the world – GIA, IGI, and HRD.

Documents issued by the labs of GIA, the oldest and biggest gemological institute in the world, are the most sought-after and recognizable certificates in the diamond industry – and our stones have them. Above all, we’re making sure that the information we provide is reliable because only a trustworthy partnership between us and our clients can forge bonds that will last for years.
