Learn what certification means and why it matters before you customize your piece.

Gemological Institute of America                     International Gemological Institute

     These certifications represent accuracy, integrity, and global recognition — the same standards upheld by heritage maisons and reflected in every diamond at Bowtie Lab Diamonds.

Why Certification Matters for Lab-Grown Diamonds

Lab-grown diamonds are chemically and visually identical to natural diamonds, but they’re created in controlled environments.

Certification ensures that:

• You know exactly what you’re getting  
• Clarity and characteristics are independently verified  
• Pricing aligns with quality and specifications

Certification ensures that your lab-grown diamond has been independently evaluated for quality, clarity, and characteristics — just like natural diamonds.
Every certified lab-grown diamond we use comes with a trusted grading report so you can shop with confidence.

What’s Included in a Certification Report

✔ Clarity Grade (e.g., VS1, VVS2)

Evaluated under high magnification to determine internal characteristics.

✔ Carat Weight

Verified and measured precisely to ensure accuracy.

✔ Cut & Polish

Reflects how well the diamond is finished for brilliance.

✔ Measurements & Proportions

Exact dimensions of the stone.
