IGI Certified

IGI Certified – Verified Natural Diamonds and Gemstones

In the world of fine jewelry, especially when it comes to natural diamonds and gemstones, authenticity isn’t optional—it’s everything. At Gold Stone Diamond, we proudly present only IGI Certified natural stones, each one independently verified for origin, quality, and ethical sourcing. Every certified piece tells a story backed by science and written by nature.

Unlike artificial or treated stones, IGI-certified gems come with documented proof of natural formation. These aren’t lab products. They are geological masterpieces shaped over millions of years.

What is IGI?

The International Gemological Institute (IGI) is a globally recognized gem laboratory established in Antwerp in 1975. With locations in New York, Dubai, Mumbai, and beyond, IGI is known for grading both loose stones and finished jewelry. Their certification system is used by elite jewelers, auction houses, and collectors worldwide.

What’s Inside an IGI Certificate?

Each IGI report offers detailed gemological analysis to help buyers understand exactly what they're purchasing. It includes:

  • Exact carat weight and measurements
  • Color and clarity grades
  • Cut, polish, symmetry evaluations
  • Fluorescence and internal inclusions
  • Microscopic mapping of characteristics
  • Laser inscription on the stone's girdle (where applicable)
  • Clear confirmation of natural origin
  • Unique report number with online verification

Why IGI Certification Matters for Natural Stones

When purchasing natural diamonds or gemstones, an IGI certificate serves as proof that what you're investing in is truly from nature—not synthetically produced or treated. It adds value, increases trust, and ensures you're not overpaying for something that isn’t genuine.

Whether it's a 1-carat solitaire or a rare sapphire, every certified piece from Gold Stone Diamond is selected for its origin, brilliance, and integrity.

IGI vs. Other Labs

While GIA and HRD are well-known for loose stone grading, IGI specializes in evaluating finished jewelry—including mounted stones in rings, earrings, and pendants. This makes it ideal for customers who want verified quality without having to separate a stone from its setting.

Verification and Security

Each IGI certificate comes with a unique report ID and scannable QR code. You can verify the stone’s report at any time via IGI’s official site:
