This guide explains what an IGI certificate is, why it is important, and how to verify it. We will show you how to check the authenticity of lab-grown diamonds easily.

What Is an IGI Certificate/Report Number?

An IGI certificate is an official diamond grading report issued by the International Gemological Institute, also known as IGI.

IGI is a trusted diamond grading lab that checks and records a diamond’s quality using global grading standards. For lab grown diamonds, this certificate confirms the diamond is real and properly graded.

 

Every grown diamond certificate includes a unique IGI report number.

This number allows you to check the diamond’s grading details online. It is one of the most important parts of the certificate.

Some diamonds have a laser inscription of the report number on them. This depends on the design and size.

An IGI certificate for lab grown diamonds shows clear details about the diamond’s quality, including:

  • Cut grades
  • Clarity grades
  • Color grade
  • Clarity and carat weight
  • Diamond measurements
  • Confirmation of lab grown diamond IGI certification

This report helps buyers understand exactly what they are buying.

What Is Inside a Diamond Grading Report?

An IGI grading report gives a full breakdown of the diamond’s quality.

Cut Grades

Cut grades show how well the diamond reflects light. A good cut creates more sparkle and brilliance.

Clarity Grades & Naked Eye Clarity

Clarity grades describe tiny marks inside or on the surface of the diamond. Many diamonds offer naked eye clarity, which means you cannot see these marks without close-up tools.

Clarity & Carat Weight

Carat weight tells you the diamond’s size. Clarity affects how clean it looks. Both details appear clearly in the report so you can judge the diamond’s quality easily.

IGI vs GIA for Lab Grown Diamonds

When comparing IGI vs GIA for lab grown diamonds, both are respected grading labs.

For lab grown diamonds:

  • IGI is more commonly used
  • Reports are easier to understand
  • Verification is simple and fast
  • Widely accepted in the industry

The most important thing is not the lab's name. What matters is that the diamond has a certificate for lab grown diamonds that you can check yourself.

Etheically Sourced Lab Grown Diamonds

Many buyers care about responsible choices.

Lab grown diamonds are called ethically sourced lab grown diamonds. This is because they do not need traditional mining. IGI certification clearly identifies the diamond as lab grown, which supports transparency and honest sourcing.

What are lab-grown diamonds?

Lab-grown diamonds are real diamonds created in a controlled laboratory using advanced technology. They share the same chemical, physical, and optical properties as mined diamonds. The difference is only how they are formed, not how they look, sparkle, or last.

How are lab-grown diamonds made?

Lab-grown diamonds are created using two proven methods:

  • HPHT (High Pressure High Temperature)
  • CVD (Chemical Vapor Deposition)

Both methods recreate the natural conditions under which diamonds form, resulting in genuine diamonds with the same crystal structure as mined ones.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are 100 percent real diamonds. They are not imitations or simulants.

 

They are made of carbon atoms arranged in the same crystal structure as natural diamonds, giving them the same brilliance, hardness, and durability. Even trained professionals need special equipment to tell them apart from mined diamonds.

Are lab-grown diamonds graded and certified?

Yes. Lab-grown diamonds are graded and certified just like natural diamonds.

 

At Jewellery Direct Factory, our lab-grown diamonds come with an IGI lab diamond certificate, which is an official grading report issued by a trusted diamond grading lab. This report details the diamond’s cut, color, clarity, and carat weight.

 

Please note: We provide IGI certification for lab-grown diamonds 1 carat and above. Smaller diamonds are still high-quality, but IGI certification is reserved for stones 1 carat or larger to ensure verified grading and authenticity for our investment-grade diamonds.

What is an IGI certificate and why does it matter?

An IGI certificate is an independent diamond grading report issued by the International Gemological Institute.

It matters because it confirms:

  • The diamond is real and lab grown
  • The diamond’s quality is professionally graded
  • The grading follows global industry standards

Each certificate includes an IGI report number that you can verify online for peace of mind.

How do I check my IGI report number?

You can do an IGI certificate number check easily.

 

Simply visit the official IGI website, enter your IGI report number, and view the verified grading report. This allows you to confirm the diamond’s details directly from IGI’s database.

Can IGI certificates be faked?

Printed documents can be copied, but online verification cannot be faked.

 

That is why JDF always provides the IGI report number so customers can perform an IGI diamond certificate verification themselves. This is the safest way to confirm authenticity.

Are lab-grown diamonds considered ethical?

Yes. Lab-grown diamonds are often viewed as an ethically sourced option.

 

They are created without traditional mining, which reduces environmental impact and avoids concerns linked to mining practices. For many women, this makes lab-grown diamonds a more responsible and thoughtful choice.

How do lab-grown diamonds compare to natural diamonds?

Lab-grown diamonds and natural diamonds look the same and perform the same.

Key differences:

  • Lab-grown diamonds are usually more affordable
  • They offer clearer sourcing transparency
  • They avoid mining-related environmental impact

The choice comes down to personal values, budget, and preference.

Are lab-grown diamonds more affordable than natural diamonds?

Yes. Lab-grown diamonds are generally priced lower than natural diamonds of similar quality. This allows you to choose a larger size or higher clarity without increasing your budget.

Do lab-grown diamonds have the same quality as natural diamonds?

Yes. Lab-grown diamonds are graded using the same 4Cs: Cut, Color, Clarity, and Carat weight.

 

Many lab-grown diamonds offer excellent clarity, often appearing clean to the naked eye, and can achieve the same level of brilliance as natural diamonds.
