By Georgie Okoh, founder of ỌLA Fine Gems & Jewelry

Natural diamonds are not automatically unethical, and lab grown diamonds are not automatically ethical. A meaningful comparison considers the specific supply chain: where a diamond was mined or grown, who cut it, working conditions, environmental impacts, and what a seller can actually document.

If your first reason for choosing a lab grown diamond is the price, you can say that. Wanting a beautiful ring within your budget does not require a moral justification.

What deserves more scrutiny is the leap from “this costs less” to “this purchase saves African children.”

As a Nigerian-born, Black jewelry designer who works with both natural and lab grown diamonds, I want a better conversation. One that takes exploitation seriously without reducing an entire continent to an image of suffering.

African children are people, not a jewelry marketing argument

When I discuss sourcing natural diamonds, someone inevitably asks how I can do that as a Black woman. Often, the question arrives with an assumption that a natural diamond must represent the exploitation of African children.

Child labor and human rights abuses in diamond supply chains are real concerns. Human Rights Watch has documented serious sourcing risks and gaps in jewelry companies’ efforts to address them. Those concerns deserve investigation, accountability, and action.[1]

But “Africa” is not a mine. It is a continent of distinct countries, communities, workers, and economies.

There is something deeply uncomfortable about invoking African children as proof of your own goodness while showing little interest in the lives, livelihoods, or perspectives of African people.

My criticism is not of everyone who chooses lab grown. I source lab grown diamonds myself. It is of a sales narrative that lets the conversation end as soon as the less expensive option feels morally reassuring.

If concern for workers is the reason for your choice, that concern should travel through the entire supply chain.

Are natural diamonds ethical?

A natural diamond’s origin alone cannot establish whether it was responsibly sourced. The relevant questions concern the mine, trading chain, cutting and polishing facilities, and the evidence available about those operations.

Natural diamond mining has documented human rights risks. A responsible discussion cannot minimize them. Equally, the existence of abuse does not establish that every natural diamond has the same history.

Botswana illustrates why country-specific context matters. The International Monetary Fund has described how diamond revenues, together with economic policy, helped support infrastructure and public spending, including health and education. It has also identified the limitations of dependence on diamonds.[2]

That does not certify an individual Botswana diamond as ethical or erase concerns about mining. It does challenge the assumption that African communities can only be harmed by the natural diamond industry.

A serious ethical discussion asks who benefits, who bears the risks, and how those outcomes can improve.

Does “conflict free” mean a diamond is ethical?

No. “Conflict free” is narrower than a comprehensive ethical sourcing claim.

The Kimberley Process regulates international trade in rough diamonds. Its definition of conflict diamonds concerns rough diamonds used by rebel movements or their allies to finance conflict against legitimate governments.[3]

That definition does not cover every possible labor, human rights, or environmental problem in a diamond’s journey. Human Rights Watch has criticized gaps in jewelry certification systems and supply chain transparency.[4]

A conflict free assurance is therefore not a complete answer to questions about wages, child labor, working conditions, or environmental damage.

Ask what a seller means by the term and what evidence supports it. A reassuring label should start the conversation, not finish it.

Are lab grown diamonds more ethical than natural diamonds?

Lab grown diamonds avoid the extraction of a newly mined diamond, but their origin does not guarantee fair labor or low environmental impact.

Lab grown diamonds are diamonds. GIA explains that they have essentially the same chemical, physical, and optical properties as natural diamonds.[5] Their material identity, however, tells us nothing about how workers were treated.

A diamond grown in a factory still needs people to operate equipment, cut and polish the stone, and move it through the supply chain.

In reporting published in 2025, The Indian Express described a strike by hundreds of workers at a lab grown diamond factory in Surat, India, after alleged cuts to cutting and polishing wages. The report included workers’ accounts of the effect on their earnings.[6]

That is evidence of a labor dispute at a particular operation. It is not evidence that every lab grown diamond producer exploits workers.

It is also a clear reason to question the idea that laboratory production makes labor concerns disappear.

If workers matter when a diamond is mined, they should matter when a diamond is grown, cut, and polished.

Are lab grown diamonds better for the environment?

There is no reliable category-wide answer without knowing the production conditions and how the comparison was measured.

Natural diamond mining can disturb land and ecosystems. Laboratory growth requires energy. The electricity source, production efficiency, and boundaries of an environmental assessment affect the comparison.

In its 2022 sustainability report, GIA described the environmental impact of laboratory-grown diamonds as an unresolved question and noted the energy required from fossil or renewable sources.[7] That dated assessment should not be mistaken for a measurement of any particular producer today.

For a specific diamond, ask for producer-specific evidence. What electricity powers the growth facility? Does a footprint calculation cover growth alone, or also cutting, polishing, and transport? What information supports the claim?

“Grown in a lab” describes a production method. It does not, by itself, measure the environmental footprint.

You can choose lab grown because it fits your budget

You are allowed to want a larger diamond. You are allowed to love fancy colors, unusual cuts, or a design that becomes more accessible with a lab grown center stone.

You do not need to turn those preferences into a claim that someone choosing natural has failed a moral test.

The same standard applies in the other direction. Choosing natural does not make someone more discerning, more committed to their relationship, or more deserving of fine jewelry.

The useful conversation is about your preferences, your budget, your values, and the information available about the particular stone.

Affordability is a valid reason. An ethical claim needs evidence.

What should you ask before buying a diamond?

Whether you are considering natural or lab grown, start with these questions:

1. Where was this diamond mined or grown? Ask what is known and what remains unverified.
2. Where was it cut and polished? The origin of the rough is only one part of its journey.
3. What documentation supports the sourcing claims? Ask sellers to distinguish supplier assurances from independent verification.
4. How are labor risks assessed? Look for an explanation that goes beyond the words “ethical” or “conflict free.”
5. What supports environmental claims? Ask about the producer, energy source, assessment method, and activities included.
6. What does the grading report establish? A gemological report can describe a diamond’s characteristics. It should not be treated as proof of fair wages or a complete ethical history.

A seller may not have every answer. The willingness to distinguish what is known from what is assumed matters.

How I approach the conversation at ỌLA

ỌLA Fine Gems & Jewelry is my bespoke jewelry atelier in the Los Angeles Jewelry District. I work with natural and lab grown diamonds, including unusual and custom cuts, to create pieces around the person who will wear them.

My work draws on the griot tradition of West African storytelling and oration. That makes me especially attentive to the stories we repeat about people, materials, and value.

I will not reduce African people to a marketing device to sell you a diamond.

I want you to ask questions. Ask me about the stone, the design, the sourcing information available, and the limits of that information. A meaningful conversation has room for both beauty and scrutiny.

To begin a bespoke piece with ỌLA, submit a commission inquiry and tell me what you envision. We can discuss natural and lab grown options in the context of your design, budget, and priorities.

Frequently asked questions

Do all natural diamonds involve child labor?

No. Documented child labor risks in parts of the industry do not establish that every natural diamond involves child labor. Assess the specific supply chain and the evidence behind a seller’s claims.

Are lab grown diamonds free from labor concerns?

Laboratory origin does not guarantee fair working conditions. Growth, cutting, and polishing operations still require scrutiny, including wages and worker protections.

Is buying a lab grown diamond automatically better for African communities?

No automatic benefit can be inferred from that choice alone. African communities have different relationships with diamond production, including livelihoods and public revenues. Claims about benefits should identify the community and evidence involved.

Can a diamond grading report prove ethical sourcing?

A diamond grading report is not a complete ethical sourcing audit. Read what the particular report covers and request separate evidence for labor, traceability, and environmental claims.

Does ỌLA work with natural and lab grown diamonds?

Yes. ỌLA Fine Gems & Jewelry works with both within bespoke jewelry projects. The choice depends on the design, the client’s preferences, budget, and sourcing considerations.
