Diamond Certification

A diamond grade means nothing if it comes from the seller alone.

That is why every Apekani diamond is graded by an independent laboratory — the International Gemological Institute (IGI) — and ships with its own certificate. You never have to take our word for what you’re buying. You have an impartial third party’s.

 

What IGI is

IGI is one of the world’s largest and most established independent gemological laboratories, and a global leader in grading lab-grown diamonds specifically. “Independent” is the key word: IGI has no stake in the sale. Its only job is to assess the stone accurately.

 

What your Certificate tells You

Each IGI report documents the diamond’s key characteristics so you can verify exactly what you paid for:

• Carat weight — the precise weight of the stone.
• Colour grade — where it sits on the D-to-Z scale.
• Clarity grade — the level of natural inclusions.
• Cut grade — how well it has been proportioned and finished.
• Measurements and proportions — the stone’s exact dimensions.
• A unique report number — and on many stones, a matching laser inscription on the girdle, invisible to the naked eye.

How to Verify your Diamond

Every IGI report carries a unique number. You can enter it directly into IGI’s own online report-check on their website to confirm the certificate is genuine and matches your stone. If your diamond is laser-inscribed, the number on the girdle will match the report — a direct link between the paper and the physical stone.

 

Why This Matters More for Lab-Grown

Because lab-grown diamonds are newer, trust and transparency matter even more. Independent certification is how a serious brand proves its quality claims rather than simply asserting them. It is the difference between “trust us” and “verify it yourself.” We will always choose the second.

 

A Note on Our Standards

Across our collection we select for Excellent or Ideal cut, F–H colour, and typically VS clarity. Your certificate is how you confirm the specific grades of the specific stone you’ve chosen — in writing, from IGI, not from us.
