International Gemological Certificates: Your Assurance of Quality and Authenticity

1) Gemological Institute of America (GIA)

Every diamond in our selection weighing 0.30 carats or more comes with a GIA certificate.

Established in 1931, the Gemological Institute of America (GIA) is the world's leading authority in diamond grading.

GIA's mission is to ensure public trust in gemstones and jewelry by upholding the highest standards of integrity, science, and professionalism through education, research, laboratory services, and instrument development.

A public non-profit institute, GIA is the leading source of knowledge, standards, and education on diamonds and gemstones. As the world leader in gemological research, GIA's groundbreaking discoveries continue to advance our understanding of diamonds and the colored gemstone world. Through research, education, and unbiased gem evaluation and analysis, GIA is committed to protecting gemstone and jewelry consumers by setting global quality standards.

2) IGS London

Every piece of jewelry we offer is covered by an international gemological certificate from IGS London.

IGS London originated as part of the international network of the Gemological Institute of America (GIA). Since 2004, IGS has been issuing its own certificates (the most detailed jewelry certificates with precious and semi-precious stones in the world), but still adheres to the grading criteria adopted by the Gemological Institute of America (GIA).

They have set new standards in jewelry certification and innovation, as each of their certificates, in addition to all the characteristics of the jewelry, has a photo of the jewelry and a unique Report number. With this number, the authenticity of the certificate can be checked in their database on their website. You have the option to go directly to their website and change the certificate's Report number and save it in their database so that only you have access to that certificate.

The certificates themselves are also confirmation that all diamonds used in the production of our jewelry are purchased from legal sources that are not linked to conflict zones "conflict free diamonds", which is fully in accordance with the regulations of the United Nations decision!

3) GRS SWISSLAB Certificates

Sapphires, rubies, and emeralds of larger carats, along with IGS London certificates, can be sent for additional GRS SWISSLAB certification upon customer request. GRS SWISSLAB is a laboratory specialized in assessing the quality and origin of colored gemstones, and strives for excellence in research.
