The Elarion Diamond Certification Guide

When investing in a diamond, beauty is only half the story. True luxury lies in trust, authenticity, and assurance. At Elarion, every lab-grown diamond we offer is accompanied by an independent IGI certificate — a globally recognised document that guarantees your diamond’s quality and integrity.

Certification is more than paperwork; it’s your diamond’s passport — detailing its journey, characteristics, and unique identity.

Why Diamond Certification Matters

Transparency – Know exactly what you’re purchasing.
Trust – Independent grading ensures accuracy, not marketing claims.
Value Protection – Certified diamonds retain long-term value and recognition.
Peace of Mind – A certificate is your guarantee that your diamond is genuine and ethically sourced.

Who Are the Diamond Grading Laboratories?

There are multiple grading labs worldwide, but not all are created equal. Here’s an overview of the most recognised names:

 

  • GIA (Gemological Institute of America) – Highly respected for natural diamonds, but less consistent with lab-grown.
  • HRD (Hoge Raad voor Diamant, Antwerp) – European grading body with a long history in natural diamonds.
  • IGI (International Gemological Institute) – The leading global authority for lab-grown diamond certification, trusted for accuracy, consistency, and innovation.

What Does an IGI Certificate Include?

An IGI Diamond Report provides a detailed, independent analysis of your diamond’s unique characteristics, including:

 

  1. Carat Weight – The exact weight of the diamond.
  2. Cut Grade – How well the diamond is proportioned for brilliance.
  3. Colour Grade – An objective assessment of the diamond’s colour, from D (colourless) onwards.
  4. Clarity Grade – The presence (or absence) of natural inclusions or blemishes.
  5. Shape & Measurements – Dimensions, table size, and proportions.
  6. Laser Inscription Number – Your diamond’s unique certification number, inscribed on its girdle.

How to Verify Your IGI Certificate

IGI certificates are digital as well as physical. With the unique report number, you can:

 

  • Visit the official IGI online database.
  • Enter your diamond’s report number.
  • Instantly access and verify your diamond’s grading.

Why Elarion Chooses IGI

While some brands use a mix of certifications, we have chosen IGI exclusively for three reasons:

 

Global recognition – Trusted by jewellers and consumers worldwide.
Lab-grown expertise – IGI pioneered standards for lab-created diamonds.
Consistency & precision – Ensuring that your diamond’s grading is accurate, fair, and universally respected.

 

At Elarion, we believe a diamond is more than sparkle — it’s a promise. That promise is only as strong as the certification behind it.
