When purchasing a diamond — especially online — one question matters above all: How do you know the quality is real?
The answer lies in independent certification.
At Her Crown, every diamond comes with an official grading report from International Gemological Institute (IGI).
But what does that mean, and why does it matter for you?
What Is IGI?
The International Gemological Institute (IGI) is one of the world’s largest and most respected independent diamond grading laboratories.
Founded in 1975, IGI operates in major diamond centers worldwide, including:
• Antwerp
• New York
• Mumbai
• Hong Kong
IGI evaluates both natural and lab-grown diamonds using internationally recognized grading standards.
An IGI certificate is an unbiased, third-party assessment of a diamond’s quality.
This means the diamond’s specifications are verified by professional gemologists — not by the seller.
What Information Does an IGI Certificate Include?
An IGI diamond report provides detailed grading based on the 4Cs:
1. Cut
Measures how well the diamond reflects light.
2. Color
Grades the absence of color (D is the highest grade).
3. Clarity
Evaluates internal and external characteristics.
4. Carat Weight
Measures the diamond’s weight and size.
Additionally, IGI reports include:
• Polish
• Symmetry
• Fluorescence
• Measurements
• Laser inscription number (if applicable)
This transparency allows customers to verify exactly what they are purchasing.
Why Is IGI Certification Important?
1. Independent Verification
An IGI certificate ensures the diamond’s specifications are confirmed by a third-party laboratory — not self-claimed by a brand.
This removes guesswork and protects buyers from misleading grading.
2. Standardized Global Grading
IGI follows strict grading protocols. A D color VVS1 diamond graded by IGI meets consistent international standards.
This ensures fairness, comparability, and credibility as well as transparency for online purchases.
3. Confidence in Lab-Grown Diamonds
IGI is one of the leading authorities in grading lab-grown diamonds.
Every Her Crown diamond is:
• Lab-grown
• D color
• VVS1 clarity
• Excellent cut, polish, and symmetry
IGI certification verifies these standards independently. Every Her Crown ring comes with IGI certificate with unique report number and you can verify at International Gemological Institute
IGI vs Non-Certified Diamonds
Some jewelry on the market is sold without any independent grading report.
Without certification:
• Quality cannot be independently verified
• Claims rely solely on the seller
• Comparison becomes difficult
• Resale or appraisal is less transparent
Certification protects the customer.
At Her Crown, we believe transparency builds trust.
