Yes, lab-grown diamonds are certified. Just like natural diamonds, lab-grown diamonds can receive an official diamond certificate that verifies their authenticity, quality, and grading. Certification is essential when purchasing a lab-grown diamond, as it ensures transparency and protects buyers from misleading or incomplete information.

A diamond certificate is an independent assessment issued by a gemological laboratory. It confirms that the stone is a real diamond and provides a detailed evaluation of its characteristics.

For lab-grown diamonds, certification is especially important because it:

• Confirms the diamond is not a simulant or imitation

• Clearly states that the diamond was created in a laboratory

• Provides objective quality grading

• Builds trust and long-term confidence

Without certification, it is impossible to accurately assess a lab-grown diamond’s quality or value.

A lab-grown diamond certificate follows the same internationally recognised grading standards as natural diamonds. It is based on the 4Cs:

• Cut – How well the diamond reflects light

• Color – The color grade of the stone

• Clarity – Internal and external characteristics

• Carat Weight – The diamond’s weight

In addition, lab-grown diamond certificates always include origin disclosure, clearly stating that the diamond is laboratory-grown. Many stones also feature a laser inscription that matches the certificate number.

The most respected gemological laboratories in the world certify lab-grown diamonds, including GIA and IGI.

• GIA applies very strict grading standards and is globally recognised for precision

• IGI is the leading authority in lab-grown diamond certification and is widely used in fine jewelry

Both certificates are internationally accepted and trusted.

The structure of the certificate is nearly identical. The key difference is transparency about origin.

A lab-grown diamond certificate will always specify:

• That the diamond is laboratory-grown

• The growth method, such as CVD or HPHT

• Unique identification details

This ensures a clear distinction between natural and lab-grown diamonds at all times.

Yes. Purchasing a certified lab-grown diamond is strongly recommended.
