Virtual AppointmentWhat is Diamond Certification?
A diamond certificate—also known as a grading report—is an official document issued by an independent gemological laboratory. It verifies the diamond’s key characteristics, including the 4Cs: Cut, Color, Clarity, and Carat Weight.
Why is Diamond Certification Important?
- Ensures transparency in what you’re buying.
- Provides proof of authenticity and quality.
- Helps determine a diamond’s market value.
GIA Certification – The Global Standard
The Gemological Institute of America (GIA) is one of the most respected and recognized diamond grading authorities worldwide.
Why choose GIA?
- Known for strict grading standards.
- Widely trusted by jewelers and consumers.
- Offers unbiased, consistent evaluations.
IGI Certification – Precision & Popularity
The International Gemological Institute (IGI) is one of the leading authorities for lab-grown and natural diamonds alike.
Why choose IGI?
- Reliable grading with fast turnaround times.
- Popular for engagement rings and modern buyers.
- Provides laser inscription options for added security.
GIA vs IGI – What’s the Difference?
Both GIA and IGI are respected, but their grading scales can differ slightly.
GIA: Often considered the industry benchmark for traditional diamonds.
IGI: Leading standard for lab-grown diamonds due to accessibility and expertise.
At LabGrownBox, we proudly offer diamonds certified by both institutes, giving you flexibility and confidence in your choice.
How to Read a Diamond Certificate
Each report includes key details such as:
- Cut grade – Sparkle and proportions.
- Color grade – From D (colorless) to Z (light color).
- Clarity grade – Inclusions and blemishes.
- Carat weight – Diamond’s size.
- Laser inscription number – Matches your certificate for authenticity.
