At Fortuna, we have always valued clarity in both diamonds and communication. That’s why we’re excited to announce some significant industry news: The International Gemological Institute (IGI) now officially certifies the 4Cs (Cut, Clarity, Color, and Carat) of lab-grown diamonds. This development brings lab-grown diamonds closer to becoming luxury items while placing buyer trust at the forefront.

The IGI is one of the most respected independent gem labs globally. Its grading system is acknowledged by diamond buyers and jewelers around the world.
With the new certification, lab-grown diamonds will now come with detailed documents, just like their natural counterparts. These certifications will highlight:
Cut: This refers to how well a diamond has been shaped. For instance, a well-cut diamond can reflect light brilliantly, enhancing its sparkle and visual appeal.
Clarity: This is the measure of internal flaws or 'inclusions.' For example, a clarity rating might show that a diamond has no visible flaws under 10x magnification, making it exceptionally clear.
Color: This measures the lack of color in the diamond. A rated D diamond is completely colorless, while lower grades may display a tint.
Carat: This indicates the weight of the diamond. One carat is equivalent to 0.2 grams. For example, a 1.5-carat diamond weighs 0.3 grams.
This certification not only assures the quality of the diamonds but also gives buyers the confidence to make informed decisions.
What This Means for You — the Fortuna Customer
With every Fortuna lab-grown diamond now accompanied by an IGI certificate detailing its 4Cs, buyers receive the same grading standards used for mined diamonds.
Increased Transparency: Buyers can see detailed reports on the quality of their diamonds, fostering trust.
Enhanced Confidence: Knowing that these diamonds come with an IGI certification reassures customers about their investment.
Commitment to Quality: There's no compromise on beauty or brilliance. For example, a lab-grown diamond can have the same aesthetic and structural quality as a natural diamond, often at a lower cost.
This reinforces our promise: to provide authentic, ethical luxury that is accessible and traceable, ensuring your jewelry is not only beautiful but also responsibly sourced.
The Future of Diamonds Is Certified
The shift in the industry extends beyond paperwork. IGI certification is a badge of validation for modern, eco-conscious luxury. It empowers you, the buyer, with complete clarity—making lab-grown diamonds strong contenders in the fine jewelry market.
