A diamond is a diamond.

That is chemistry, not marketing. Lab-grown diamonds and mined diamonds share the same atomic structure, the same hardness, the same brilliance. Trained gemologists cannot tell them apart by eye.

So the question is not whether one is real and the other is not.

The question is what was paid to bring it into existence.

What gets paid for a mined diamond

For each carat pulled from the earth, peer-reviewed life-cycle assessments estimate:

• 480 to 750 litres of water consumed
• 100 to 250 square metres of land disturbed
• 125 to 160 kilograms of carbon dioxide released
• 2.63 tonnes of mineral waste generated

These are conservative figures. They do not capture the deforestation, the soil erosion, or the chemical contamination of water sources that follows many open-pit operations.

And the land is rarely empty.

Who was already there

In Marange, Zimbabwe, the discovery of diamonds in 2006 led to the forced displacement of the Chiadzwa community. Researchers and Human Rights Watch have documented years of killings, beatings, and forced labour at the site that followed.

In northern Canada, diamond mines built on Indigenous lands have been linked to rising violence against Indigenous women — connected in part to the temporary worker camps that house transient miners near remote sites. Researchers at Queen's University and the Native Women's Association of the Northwest Territories have documented this directly.

In Uganda, international mining companies have been documented exploring on Karamojong land without the free, prior, and informed consent of those communities — the international standard for Indigenous rights established by the United Nations.

These are not historical anecdotes. They are current.

The Kimberley Process, and what it does not cover

The Kimberley Process Certification Scheme was created in 2003, in the wake of civil wars in Sierra Leone, Angola, and the Democratic Republic of Congo that had been financed by rough diamond sales. It has reduced what it formally defines as "conflict diamonds" from approximately 15% of global supply in the 1990s to less than 1% today.

That is real progress. It should be acknowledged.

But the definition is narrow. The Kimberley Process only covers diamonds that finance armed groups fighting governments. It does not cover diamonds mined under forced labour, under child labour, or with state-sanctioned violence against communities. By one peer-reviewed estimate, roughly one in five diamonds by volume came from conditions that could not be called sustainable or ethical as recently as 2017.

A certificate does not always tell the full story.

What gets paid for a lab-grown diamond

A lab-grown diamond is created in a chamber, using one of two methods: High Pressure High Temperature, or Chemical Vapor Deposition. Both replicate, with electricity, the conditions that produced diamonds underground over a billion years.

The footprint is smaller. It is not zero.

A single carat of lab-grown diamond requires around 250 kilowatt-hours of electricity. Where that electricity comes from matters enormously. Roughly 60% of global lab-grown production happens in regions where coal still dominates the grid. Diamonds produced on those grids can carry a carbon footprint comparable to mined stones.

Lab-grown diamonds produced on renewable energy tell a different story. Independent comparisons place their emissions at 15 to 50 kilograms of CO₂ per carat, against 125 to 160 kilograms for mined. On water and land, the difference is not close. Roughly 50 to 80 litres of water per carat versus 480 to 750. Less than one square metre of land disturbed per carat, versus 100 to 250.

No displacement. No mine. No certificate whose enforcement you have to take on faith.

Why illi chose lab-grown

We made this choice for two reasons.

The first is ethical. We do not believe the beauty of a stone is worth the displacement of a community or the destruction of a place. Lab-grown diamonds remove that question entirely. There is no land to scar. There is no community to relocate.

The second is environmental. Sourced from facilities powered by renewable energy — which is the only kind we will work with — a lab-grown diamond is the lowest-impact way to wear brilliance.

A note on what we are not saying

We are not saying that every miner is complicit, or that every mining community wants the mines gone. The diamond industry employs millions of people. In countries like Botswana, where diamond revenue has funded schools, hospitals, and a generation of national development, the industry has been a force for good.

We are saying that, between a stone whose origin we can fully account for and a stone whose origin carries documented harm, we choose the first.

This is not the only ethical position. It is ours.
