Lab-Grown Diamonds: What You Need to Know

Last updated on Sep 08, 2026

Lab-grown diamonds are real diamonds created in a controlled laboratory environment rather than formed naturally underground.

They have essentially the same crystal structure and main chemical composition as natural diamonds and offer very similar physical and optical properties.

Are Lab-Grown Diamonds Real Diamonds?

Yes.

Lab-grown diamonds are diamond material, not diamond simulants.

They are different from moissanite and cubic zirconia, which are different materials that can visually resemble diamonds.

How Are Lab-Grown Diamonds Made?

The two main production methods are:

  • HPHT (High Pressure High Temperature)

  • CVD (Chemical Vapor Deposition)

Both methods create conditions that allow diamond crystal growth.

Can You Tell Lab-Grown and Natural Diamonds Apart by Eye?

In many cases, high-quality lab-grown and natural diamonds can look extremely similar to the naked eye.

Professional gemological laboratories can identify their origin using specialized equipment and analysis.

What Shapes and Sizes Are Available?

Lab-grown diamonds may be available in many popular shapes, including:

  • Round

  • Oval

  • Pear

  • Marquise

  • Emerald

  • Radiant

  • Cushion

  • Princess

  • Asscher

  • Heart

Availability depends on the specific project, size, color, clarity, and current supply.

Do Lab-Grown Diamonds Come With Certificates?

Certification depends on the individual stone and product.

Some lab-grown diamonds may be available with grading reports from recognized gemological laboratories, but customers should not assume that every stone automatically includes a certificate.

Please ask our sales team to confirm certification for the specific diamond you are considering.

Are Lab-Grown Diamonds Suitable for Engagement Rings?

Yes. Lab-grown diamonds are commonly used for engagement rings, wedding jewelry, earrings, necklaces, and other fine jewelry.

They are highly durable and suitable for everyday wear.
