Every diamond has a story. From quality evaluation to diamond origin, certification provides the details you need to make a confident choice. Learn how IGI certification helps you understand the quality behind your lab-grown diamond.
What is an IGI Diamond Certificate?
The International Gemological Institute (IGI) is one of the world's leading independent gemological laboratories, specializing in diamond and gemstone grading.
An IGI certificate provides an objective evaluation of a diamond's characteristics, including its carat weight, color, clarity, cut, and other identifying features.
For lab-grown diamonds, an IGI report confirms that the diamond has been professionally examined and graded in accordance with recognized gemological standards.
How to Verify Your IGI Certificate
To verify an IGI diamond report, visit the IGI website and enter your report number in the certificate verification tool. The report details will be displayed, allowing you to confirm your diamond’s information and grading results.
Why Does IGI Certification Matter?
Verified Quality: Every certified diamond comes with detailed information about its quality, including the 4Cs: Cut, Color, Clarity, and Carat.
Independent Evaluation: IGI certification provides an unbiased assessment from a professional gemological laboratory—not simply a description from a jewelry seller.
Complete Transparency: Confidence Through Transparency. Your certificate allows you to verify your diamond's characteristics and make a confident purchase decision.

Why We Choose IGI Certification?
While GIA is widely recognized for its expertise in natural diamond grading, IGI has extensive experience in evaluating and certifying lab-grown diamonds. As lab-grown diamonds continue to grow in popularity, we choose IGI certification because of its specialized knowledge in this category and its detailed grading reports, providing customers with transparency and confidence in every diamond purchase.
Do All Agvana Diamonds Come With IGI Certificates?
For our gold jewelry, center stones of 1ct or larger are accompanied by an official IGI certificate, providing independent verification of the diamond’s quality and characteristics.
For select sterling silver styles, IGI certificate availability may vary by item. Diamonds under 1 ct generally do not include individual IGI certification due to their size and certification requirements.
Regardless of certification, every lab-grown diamond we use is carefully selected to meet our quality standards. We believe in being transparent about what comes with each piece, so if an IGI certificate is important to you, please contact us to confirm certificate availability before purchase.
