What Does "Lab-Grown Diamond" Mean?

A lab-grown diamond, also known as a lab-created diamond or man-made diamond, is a diamond that is created in a laboratory setting using advanced technology that replicates the natural diamond-growing process.

Despite the synthetic setting, lab-grown diamonds are real diamonds. They are chemically, physically, and optically identical to mined diamonds.

So if you’re wondering what lab-grown diamonds are called, the answer is:

Lab-Created Diamonds
Lab-Made Diamonds
Man-Made Diamonds
Engineered Diamonds
Synthetic Diamonds (in technical gemological terms)

But make no mistake—they are not fake and they are not diamond simulants like cubic zirconia.

What Are Lab-Grown Diamonds Made Of?

Lab-grown diamonds are made of pure carbon, the same element that forms natural diamonds deep within the Earth.

Under extreme heat and pressure, carbon atoms crystallize into a diamond structure. In a lab, this is achieved using one of two methods:

1. HPHT (High Pressure High Temperature)

This method mimics the natural diamond creation process by applying intense pressure and heat to a diamond seed.

2. CVD (Chemical Vapor Deposition)

What is CVD diamond?

This modern technique uses a carbon-rich gas in a plasma chamber. Carbon atoms bond and build up layer by layer to form a diamond crystal.

Both methods result in a diamond that is indistinguishable from mined diamonds, even to trained gemologists without special equipment.

What is a Lab-Cut Diamond?

The term “lab-cut diamond” is often misunderstood. There’s no special cut called “lab-cut.” The cut refers to the shape and proportions of the diamond, such as round, oval, princess, emerald, cushion, etc.

So, a lab-cut diamond simply means a lab-grown diamond that has been cut and polished into a specific shape, just like a mined diamond would be.

Lab-Grown Diamond vs Natural Diamond

Here’s a quick comparison of Lab-Grown Diamond vs Natural Diamond to clarify the similarities and differences:

Feature	Lab-Grown Diamond	Natural Diamond
Origin	Grown in a lab	Formed in Earth over billions of years
Composition	Pure Carbon	Pure Carbon
Appearance	Identical	Identical
Durability (Mohs Scale)	10	10
Certification	IGI, GIA	IGI, GIA
Price	30–50% less expensive	More expensive due to rarity
Ethical Impact	Conflict-free, eco-friendly	Often tied to mining issues
