💎 IGI Certified Diamonds – What They Are & Why They Matter

What is IGI?

The International Gemological Institute (IGI) is one of the world’s most respected and trusted diamond grading laboratories. Based in Antwerp and operating globally, IGI specializes in the certification of both natural and lab-grown diamonds, providing detailed analysis and authentication reports to ensure each stone meets the highest quality standards.

🧾 What is an IGI Certificate?

An IGI certificate is an official grading report issued by IGI that evaluates a diamond's key characteristics, including:

• Carat Weight

• Color Grade

• Clarity Grade

• Cut Quality (for rounds)

• Polish and Symmetry

• Measurements and Proportions

• Laser Inscription (if applicable)

• Certification Number

This certificate acts as a proof of authenticity, giving buyers peace of mind about what they’re purchasing.
