Lab-Grown Diamonds: Separating Fact from Myth

The rise of lab-grown diamonds has created a new choice for diamond buyers—and considerable confusion along the way.

Lab-grown diamonds are often promoted as an identical, sustainable alternative to natural diamonds. But what exactly is a lab-grown diamond, and what makes it different?

At Jewelite, we believe an informed choice begins with understanding the facts.

A Diamond, But Not a Natural Diamond

Lab-grown diamonds have essentially the same chemical composition and crystal structure as natural diamonds. They are created in laboratories using technologies such as CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature).

They can look identical to natural diamonds and require specialised gemological equipment to distinguish them.

But there is one fundamental difference:

A natural diamond is formed by nature. A lab-grown diamond is manufactured through technology.

In this sense, lab-grown diamonds are synthetic diamonds—diamonds produced artificially rather than formed naturally within the Earth.

The distinction is therefore not whether the stone has the properties of diamond. It is about origin.

Myth: Lab-Grown Diamonds Are Naturally Eco-Friendly

Because lab-grown diamonds do not involve traditional mining, they are frequently marketed as an environmentally friendly or sustainable alternative.

But lab-grown does not automatically mean low-carbon or eco-friendly.

Growing a diamond is an energy-intensive industrial process. CVD production, for example, uses powerful microwave energy to create the plasma in which diamond crystals grow. HPHT production requires extremely high pressures and temperatures. Both processes consume substantial electricity, in addition to energy used for cooling and other supporting systems.

Most importantly, the carbon footprint depends heavily on the source of that electricity.

A laboratory powered predominantly by renewable energy can have a very different carbon footprint from one relying heavily on fossil-fuel-generated electricity. Published studies have demonstrated significant variation in the energy and carbon intensity of laboratory-grown diamond production depending on technology and energy source.

“Lab-grown” describes how a diamond is made. It does not, by itself, prove that it is environmentally friendly.

Consumers should look beyond broad claims such as “eco-friendly” or “green” and ask how the diamond was actually produced and powered.

Myth: Lab-Grown Diamonds Are Rare

A natural diamond is the result of an extraordinary geological process and comes from a finite natural resource.

A lab-grown diamond, by contrast, can be produced by adding manufacturing capacity.

Natural rarity cannot be manufactured.

This difference in origin and supply is an important consideration when comparing the two.

Natural Diamonds: Supporting Communities and Economies

Natural diamonds also have an important socio-economic dimension that is often overlooked.

Diamond mining provides employment and livelihoods across mining, processing, logistics and supporting industries, particularly in countries where diamond production is a significant part of the economy. In several diamond-producing nations, revenues from the industry contribute to government income, infrastructure, education, healthcare and community development.

From Botswana and Namibia to South Africa and Canada, the natural diamond industry supports thousands of direct and indirect jobs and contributes to local economies.

This does not mean that every diamond mine has the same social or environmental impact. Responsible sourcing, ethical labour practices, environmental stewardship and transparent supply chains remain essential.

For consumers, therefore, the story of a natural diamond can extend beyond the stone itself—from its geological formation to the people, communities and economies connected to its journey from mine to jewellery.

Natural vs Lab-Grown: At a Glance

Why Origin Matters

For some buyers, appearance and price may be the primary considerations. For others, the origin of the diamond is an essential part of its meaning.

A natural diamond carries a history that begins deep within the Earth. It was formed naturally over immense geological periods before being discovered, cut and transformed into jewellery.

That story cannot be replicated in a laboratory.

At Jewelite, we choose to work exclusively with 100% natural diamonds because we believe that their natural origin, rarity and geological history are part of what makes them extraordinary.

We do not believe consumers should be misled into thinking that lab-grown diamonds are fake. They are diamonds—but they are synthetic diamonds, created through technology rather than nature.

The choice ultimately belongs to the buyer.

Our role is to make sure you understand the difference.

Natural or lab-grown. Know the difference. Choose what matters to you.
