Certification: What It Is and Why We Use It

Quality Assurance with Multiple Laboratory Partnerships

To ensure the highest standards of quality assurance and authentication for our gemstones, WRB is proud to collaborate with leading gemological laboratories including the GemResearch SwissLab (GRS), the Asian Institute of Gemological Sciences (AIGS), Gemological French Laboratory (GFCO), and Gübelin Gem Lab, in addition to offering the prestigious Gemological Institute of America (GIA) certificates for all diamond sales.

What is a GIA Certification?

Confidence in the quality and authenticity of precious stones is paramount. At WRB, we offer gemstones certified by the Gemological Institute of America (GIA), the world’s foremost authority on diamond and gemstone grading. To broaden the assurance and understanding of each gemstone’s unique qualities, we also engage with GRS, AIGS, GFCO, and Gübelin, depending on the specific characteristics and origins of the gemstone.

GIA certification entails a rigorous process of evaluating and grading diamonds and gemstones based on quality and characteristics. This comprehensive examination and analysis by trained experts, using advanced equipment, results in a detailed report covering the stone’s carat weight, cut, color, and clarity—the 4Cs.

Collaborating with GRS, AIGS, GFCO, and Gübelin

In our quest to meet the highest standards of quality and provenance, WRB collaborates with:

• GRS (GemResearch SwissLab): Known for its expertise in colored gemstones, GRS reports detail analysis and origin, adding depth to the gemstone’s story.
• AIGS (Asian Institute of Gemological Sciences): Specializing in colored gemstones, AIGS offers in-depth reports on authenticity and quality from its Bangkok base.
• GFCO (Gemological French Laboratory): Renowned for its precise gemstone evaluations, GFCO provides insights into quality and authenticity with a focus on European standards.
• Gübelin Gem Lab: Esteemed for detailed gemstone analysis, Gübelin reports offer valued assessments of a stone’s provenance and characteristics.

How Does GIA Certification Work? 

The GIA certification process is a thorough multi-step evaluation that includes grading, specialized analysis, and a comprehensive report detailing the stone’s quality and characteristics.

How Buyers Can Benefit from Laboratory Certifications 

When purchasing gemstones, requesting a certificate from GIA or reports from GRS, AIGS, GFCO, or Gübelin ensures a high level of quality assurance. These documents offer crucial information for comparing stones, assessing their value, and verifying authenticity.
