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.
An IGI certificate is an official grading report issued by IGI that evaluates a diamond's key characteristics, including:
This certificate acts as a proof of authenticity, giving buyers peace of mind about what they're purchasing.
IGI is recognized worldwide for unbiased and precise grading.
Expert gemologists back each diamond's beauty.
Certification enhances resale value and ensures you get what you pay for.
Know your diamond's exact specs with clarity, polish, and symmetry ratings.
Especially important when shopping online, where seeing the stone in person isn't always possible.
We provide IGI certification for all center stones in our engagement rings and fine jewelry. Whether you're buying a lab-grown solitaire or a multi-stone design, rest assured that your diamond is graded, authenticated, and comes with a physical IGI report shipped securely with your order.
We're happy to share the IGI certificate for any diamond you're interested in. Just ask!
