Your Guarantee of Authenticity: Diamond Certification
A diamond is a significant purchase, a symbol of a precious moment that will last a lifetime. At Monroe Yorke Diamonds, we believe your confidence in that purchase should be as strong and clear as the diamond itself. This is why every diamond we sell is accompanied by an independent, internationally recognized Diamond Grading Report.
This is not just a policy; it is the foundation of our promise to you as your personal jeweller. It is your absolute assurance of quality, authenticity, and value.
What is a Diamond Grading Report? The Blueprint of Your Diamond
Think of a diamond grading report, or certificate, as your diamond's unique fingerprint. It is a detailed blueprint produced by a third-party, independent gemological laboratory that provides an unbiased, expert assessment of the diamond's quality based on the 4Cs: Cut, Colour, Clarity, and Carat.
An independent report is non-negotiable because it ensures the diamond's quality is validated by the world's leading authorities, not just by the seller
Our Commitment to World-Leading Standards
We exclusively use the most respected laboratories for our diamonds to ensure complete transparency and trust:
- GIA for Natural Diamonds: The Gemological Institute of America (GIA) is the world's foremost authority on natural diamonds. A GIA certificate is the global gold standard, recognized for its rigorous and consistent grading standards.
- IGI for Lab-Grown Diamonds:The International Gemological Institute (IGI) is the leading authority for the certification of lab-grown diamonds, providing the same detailed analysis and assurance of quality for these modern marvels.
The Unbreakable Link: Laser Inscription
How can you be certain that the diamond you receive is the exact same one detailed in the report? The answer is through laser inscription.
As the image illustrates, each GIA and IGI certified diamond has its unique certificate number microscopically laser-inscribed onto its girdle (the thin outer edge). This inscription is invisible to the naked eye but can be verified with a jeweller's loupe.
This inscription is your unbreakable link—tangible proof that connects your physical diamond directly to its grading report, guaranteeing its identity and quality forever.
You can verify the authenticity of your diamond's report at any time using the official online portals below by entering the diamond's report number:
