I Spent More Than 20 Years Mining Diamonds. Here Is My Story.


The story behind Timeless Finery — and why an African mining insider is now writing about diamonds for you.

There is a moment at three in the morning at a small train station in Palapye, central Botswana, that returns to me whenever I think about what diamonds mean.

My mother is tending a fire. On it, maize cobs roast for passengers on the late train from Gaborone to Francistown. Boxes of bananas, apples and oranges are stacked beside her stall. I am sleeping nearby, a child pressed against the warmth of that fire, in a night that only ends when the last passenger boards and the platform empties. We will be home before dawn. She will do it again tomorrow.

My understanding of diamonds begins with that image. Not in a laboratory. Not in a jewellery store. In the lived reality of a Botswana family navigating scarcity — and in the gradual, almost miraculous transformation of that reality by a mineral pulled from the earth a few hundred kilometres away.

My name is Kgolagano Banabotlhe. I am a mineral engineer and spent more than twenty years leading diamond ore processing operations at Botswana’s largest diamond company. I worked across two of the most productive diamond mines on earth, managed large teams and significant capital budgets, and spent my career at the intersection of industrial activity and real human consequence.​

The diamond market today is not short of opinion. Retailers make the case for natural stones. Lab-grown advocates declare the traditional industry finished. Documentaries raise ethical questions. Social media flattens complexity into polarised positions. What is scarce — and what this site is built around — is the perspective of someone who worked inside the industry across its full operational depth, in Africa, without a commercial allegiance to any particular outcome.

That perspective is not inherently superior. But it is different. In a conversation this important, difference matters.

The diamond market is going through a difficult period. Prices are under pressure. Consumer confidence is uncertain. Botswana — the country that diamonds built, the country my daughters grew up in, the country whose hospitals, schools and wildlife conservation were funded largely by diamond revenues — is feeling that pressure in real terms. That reality is what prompted me to research what is happening, and to write.

My belief is simple. Clarity grows markets. Lack of clarity erodes trust and, eventually, market share. The more honestly we map what natural diamonds and lab-grown diamonds each genuinely offer — without advocacy, without alarm — the better the decisions consumers make and the healthier the industry becomes for everyone connected to it. I believe the pie can be expanded.

Timeless Finery exists to offer education grounded in operational experience. Natural diamonds and lab-grown diamonds will both be treated with rigour and fairness. No position will be taken that the evidence does not support

Before any of that, you deserve to know who is writing, where they come from, and what shaped the way they see this industry. That story starts at a fire, beside a train track, at three in the morning.

Where I Come From​

The fire, the train station, the three o’clock darkness — that is where the story begins. To understand it properly, you need to go back a little further.

Bobonong to Palapye

I was born in Bobonong, a village in eastern Botswana. When I was young, my parents made the decision many families in a developing Botswana made — they moved, following the possibility of something better. We settled in Palapye, in the Central District: nine children in a household navigating the pressures of a country that was still, in many ways, finding its feet.

Botswana in the 1970s and 80s was not yet the country it would become. Drought was not an occasional disruption; it was a recurring threat that shaped every calculation a family made. Foot-and-mouth disease, and other outbreaks, moved through livestock herds with devastating efficiency. My father had inherited hundreds of cattle from my grandfather — a form of wealth and security that represented generations of careful accumulation. Droughts and disease took most of them. What remained was the need to find another way.

My mother found it at the train station. Every evening she set up her stall — maize on the fire, boxes of bananas, apples and oranges arranged for passengers on the late service between Gaborone and Francistown. She sold until the last train cleared the platform, which often meant finishing close to three in the morning. I slept beside her stall, pressed against the warmth of the cooking fire, waking when it was time to go home.

That is where I learned work ethic. Not as a concept, but as a practice: consistent, unglamorous, and performed without the expectation of immediate reward. Whatever discipline I brought to twenty years of running industrial operations in some of the most demanding mining environments, some part of it was formed on that platform, watching my mother work.

What is also true — and worth saying plainly — is that the proceeds from selling fruit and roasted maize at a rural train station were enough to see nine children through to adulthood. That fact is not only a testament to my mother’s determination. It is a measure of the baseline conditions that diamonds were beginning to change in Botswana, through access to free healthcare, free education, free land, and subsidised housing funded mainly from mineral revenues.

A Scholarship Built on Diamonds

At nineteen I faced a decision that felt significant then and looks, in retrospect, like one of the clearest I ever made. I could take a government scholarship to study medicine, or apply for a scholarship funded through Botswana’s largest diamond company and study mineral engineering in the United Kingdom.

The scale of impact mattered to me. The diamond industry offered the chance to contribute to something that touched thousands of lives simultaneously — not one patient at a time, but through the infrastructure, employment and government revenue that a well-run mining operation generates. It also offered financial security. Salaries in the mining sector are competitive. There is nothing contradictory about wanting to do meaningful work and wanting to be paid fairly for it. The diamond industry, when it functions as it should, offers both. That combination is rare, and I found it in Botswana’s diamond industry.

I went to the University of Leeds in West Yorkshire, England, and graduated with a first-class honours degree in Minerals Engineering. The scholarship that made that possible was funded by diamond revenue. The career and professional development that followed was built on the same foundation.

Letsile Tebogo, Amantle Montsho, Nigel Amos — Batswana who have performed at the highest level on the world stage — each had their own path to excellence. Mine ran through a diamond processing plant in the Kalahari. Diamonds created the conditions for that path to exist. They set the stage. What any individual does with the stage is their own work. That stage is what I want to write about.

Twenty Years Inside the Mine

That stage was built, in Botswana’s case, by two holes in the ground — and everything that grew around them.

Two Towns Built From Nothing

Before the diamonds, there was nothing where Jwaneng and Orapa now stand. No town. No infrastructure. No community. Just the Kalahari — vast, flat, indifferent — grazing land for domestic and wild animals.

The discovery of kimberlite pipes beneath that landscape changed everything. Around those pipes, entire towns were constructed from the ground up. Housing, schools, clinics, game parks, roads and hospitals were built not as afterthoughts, but as deliberate infrastructure investments designed to attract and sustain a workforce capable of running one of the most technically demanding industrial operations on earth. Today those towns serve not only employees but multiple surrounding communities. The hospital in a Debswana mining town is not a company clinic. It is a referral facility providing advanced medical services to thousands of people who have no direct connection to mining.

My daughters, Kristen and Tatyana, grew up in those towns. They attended subsidised private schools. They had access to healthcare that most children in sub-Saharan Africa cannot take for granted. That was not luck. It was the downstream consequence of a mineral revenue model that, when managed with discipline and political will, genuinely transforms the conditions of human life. It was a gift from many, across the world, who chose natural diamonds.

I did not take that for granted then. I do not take it for granted now.

What the Mine Floor Actually Looks Like

The diamond recovery process in Botswana is not what most people imagine when they picture a mine. There is no one crouched in the earth, sifting gravel by hand. What exists is an industrial operation of high precision. Ore is blasted from hundreds of metres below ground, crushed and screened through multiple stages, then processed through dense medium separation circuits where the physics of density sort diamond from waste. X-ray and laser technology is used to further discriminate diamonds from waste rock. Every part of the process is executed to best-practice standards on safety, environmental impact, product security and efficient use of scarce resources.

Over two decades those processes were continuously refined. Water consumption came down. Energy efficiency improved. Chemical inputs such as ferrosilicon and flocculant were reduced meaningfully — not because of external pressure, but because a well-run operation pursues all-round excellence. When one of our oldest processing plants at Orapa was closed, the revenue profile was maintained through improved run rates in our Jwaneng plants. The team I led embraced the pressure of leading the group ore processing plants, innovating day and night to achieve more with less. When a jewellery buyer holds a natural diamond, they are holding the output of that entire system: the engineering, the discipline, the accumulated operational knowledge of thousands of people working across decades.

The Numbers Behind the Work — and the People Behind the Numbers

I am cautious about reducing twenty years of work to statistics. Numbers are clean in a way that operational reality rarely is. But some figures carry genuine meaning and deserve to be stated plainly.

Annual operating and capital budgets exceeded 100 million US dollars for the one department alone. Teams included more than 1,200 employees and contractors. Overall equipment effectiveness improved by up to 30% on one plant and over 15% on another. Safety incidents fell by more than 70% over three years. These are not credentials assembled for a biography. They are measurable outcomes of decisions made, cultures built and problems solved over a long career.

The achievement I return to most often is not a production figure. It is the steady growth of women in leadership positions within the ore processing department to close to 30%. Mining has a long history of exclusion. Progress inside it does not happen by accident. When I recruited managers I was deliberate about the ratio of female candidates in each process. That intentionality compounds over time.

Today, Katlego Pitso manages the recovery plant I used to run. Unami Habana is helping shape the future trajectory of Botswana’s largest diamond company. These are not diversity statistics. They are people — skilled, capable and present in roles that matter — because a pipeline was built with enough patience and intention to produce them. That is what twenty years inside the mine actually looks like.

What Diamonds Actually Did for Botswana

From Subsistence to Middle Income in One Generation

At independence in 1966, Botswana was among the poorest countries on earth — landlocked, largely arid, with a cattle-dependent economy repeatedly devastated by drought. The infrastructure inherited from the colonial period was thin. Prospects, by conventional measures, were not encouraging.

What followed over the next five decades is one of the more remarkable economic transformations in modern African history, and diamonds were at the centre of it. The joint venture model between a major international mining group and the Government of Botswana — through which the state holds a meaningful ownership stake in the country’s diamond production and captures a substantial share of the revenues — became a template for how a resource-rich developing nation could avoid the extractive traps that undermined many of its peers.

The results are visible in the data. Botswana reached nominal GDP of more than 20 billion US dollars at its peak in 2022. A country that was largely agrarian within living memory now sends its citizens to universities around the world, staffs international organisations, and produces world-class athletes who compete and win on the global stage. That trajectory was not inevitable. It required political will, institutional discipline and consistent reinvestment of mineral revenues into public goods — health, education, infrastructure and land.

It also required customers. Every person who has purchased a natural diamond over the past five decades has participated in that transformation, whether they knew it or not. The connection between a diamond sold in a jewellery store in London or New York and a child attending school in Palapye is not poetic. It is structural. It runs through royalty agreements, tax frameworks, government budgets and public spending decisions. It is real.

The Towns My Daughters Grew Up In

I have said already that Kristen and Tatyana grew up in diamond mining towns. It is worth being specific about what that meant in practice, because specificity is what separates a genuine account from a corporate responsibility report.

The schools they attended were subsidised to a level that made quality private education accessible to mining families who would not otherwise have afforded it. The hospital serving their community operated as a referral facility, with diagnostic and treatment capacity that placed it, by regional standards, in a different category from what was available in most of rural Botswana. When my colleagues and their families needed serious medical intervention, they did not need to travel to the capital. The infrastructure was there, in the town, built and maintained because the mine required a healthy, stable workforce and understood that a healthy workforce depends on a healthy community.

Consider also the pipelines that run for hundreds of kilometres bringing drinking water to surrounding villages. That logic — aligning mining needs with genuine social benefit — is how the diamond industry works when it works well. It is also the model that comes under pressure when the diamond market contracts. The pain is not abstract. It lands on schools, on hospital budgets, on the employment prospects of the next generation of young Batswana who watched an industry that shaped their parents’ lives navigate an uncertain present.

The Okavango and the 40% of Land Reserved for the Wild

There is a story about Botswana that rarely appears in content about diamonds, and it deserves to be told.

More than 40% of Botswana’s land mass is formally protected — national parks, game reserves, wildlife management areas and conservation zones that together constitute one of the most significant wildlife preservation commitments of any country on earth. The Okavango Delta, a UNESCO World Heritage Site and one of the last intact inland delta ecosystems in the world, sits at the heart of that commitment. I have visited the Okavango. I have seen elephants move through papyrus channels, the late afternoon light turning the water bronze. It is a landscape of specific, extraordinary beauty — the kind that makes you understand immediately why people have fought to preserve it.

That preservation is expensive. It requires a government with the fiscal capacity to forego short-term extraction in favour of long-term ecological and tourism value. It requires political will sustained across administrations. It requires, at its foundation, a revenue base sufficient to make that trade-off viable.

Diamonds provided that base. The conservation story and the mining story are not in tension in Botswana. They are connected. The country chose both: industrial extraction managed to high standards, alongside one of the most ambitious wildlife conservation programmes in the region. That combination is not an accident. It is policy, sustained over decades, made possible by the revenues that natural diamonds and eco-friendly tourism generate.

Why I Started Writing — and Why Independence Matters

I left operational life carrying all of that — the experience, the context and the images. What I found when I looked at how diamonds were being written about was not what I expected.

The Problem With Most Diamond Content

Search for almost anything about natural versus lab-grown diamonds and you will usually find one of two things. You will find a retailer making the case for whichever product they are carrying. Or you will find an advocate — for disruption, for ethics, for sustainability — whose conclusion was reached before the research began. You will find generalisation about diamonds irrespective of their origin.

What you rarely find is someone willing to say: both of these products have genuine merit for specific customer value profiles; both have limits; and the choice depends on what you actually value — not on what someone selling to you needs you to value.

That gap is not accidental. It is a structural feature of how information is produced and distributed in a commercial industry. An informed perspective, anchored in operational experience and prepared to present a balanced view, is genuinely scarce in this space. That scarcity is the reason this site exists.

What Prompted Me to Write

When I left operational life and began to look seriously at what was being written and said about the diamond market, I expected debate. I found noise.

Botswana — my country, whose modern development arc is inseparable from diamond revenues — is going through a period of real economic difficulty. Pressures on the natural diamond market are real and structural, not merely cyclical. The rise of lab-grown diamonds has compressed prices and complicated the value conversation in ways the industry is still working to understand. Consumer confidence, particularly among younger buyers, has been shaken by ethical concerns, price volatility and a broader uncertainty about what a diamond actually means and is worth.

I started researching. The more I read, the more convinced I became that much of the confusion in the market is not inevitable. It is the product of a conversation dominated by partial perspectives — often well-intentioned, but partial. What was missing was clarity. Not clarity as “simple answers to complex questions”, but clarity as honest, rigorous, experience-grounded analysis that trusts the reader to handle nuance.

Clarity grows markets. Lack of clarity erodes trust. A consumer who understands precisely what they are buying, why it costs what it costs, what it means in the broadest sense, and how it compares fairly to alternatives makes a better decision. A better decision is one they live with confidently, without second-guessing and without the creeping suspicion that they were sold something rather than educated into a choice.

What Timeless Finery Is — and What It Stands For

This site has no commercial relationship with any retailer, manufacturer or mining company. Whatever commercial model Timeless Finery develops as it grows, one commitment will not change: the analysis here follows the evidence, not the revenue. Editorial independence is not a feature of this site. It is the foundation.

Lab-grown diamonds will be examined here with the same rigour as natural diamonds. They are a genuine technological achievement and serve a real purpose in the market. There are buyers for whom they are the most rational choice, and I will say so plainly where the evidence supports it. There are also contexts in which the case for natural diamonds — their rarity, provenance, economic and cultural meaning — is compelling and underexamined. I will make that case too, with the same honesty and standard of evidence.

What this site will not do is tell you what to think. It will give you what I have — technical grounding, operational perspective, African context and a commitment to honest assessment — and trust you to reach your own conclusion.

What You Will Find Here

This site is organised around the questions diamond buyers actually ask — and rarely get straight answers to.

What is the difference between a natural diamond and a lab-grown diamond beyond origin? What does provenance actually mean, and does it matter to value? How should an informed buyer think about price in a market that has shifted significantly in a short time? What are the environmental and social realities of natural diamond mining — the full picture, not the version edited for a marketing brochure or a campaign against the industry? What does the science of diamond recovery tell us about why natural stones are priced the way they are?

These questions sit at the intersection of geology, economics, consumer psychology and real human consequence. Answering them properly requires more than a comparison table or a glossary of the four Cs. It requires someone who has stood inside the process.

Future posts on Timeless Finery will examine natural and lab-grown diamonds through that lens — technical where rigour is needed, personal where experience illuminates something data alone cannot. Both types of diamond will receive honest, evidence-based treatment. The goal is not to reach a predetermined conclusion. It is to map the terrain accurately so that you can navigate it with confidence.

The site will grow. The conversation will expand. Your questions, challenges and experiences with diamonds will shape where it goes. The most useful diamond education is not a monologue. It is a dialogue between people who care about getting it right.

A Final Word

I am a living example of what diamonds can do when the value they generate is captured and reinvested with discipline and genuine commitment to human development. I grew up beside a fire at a train station while my mother sold fruit to late-night passengers. I studied mineral engineering at a leading university on a scholarship that diamonds funded. I spent twenty years running operations that contributed to a country’s transformation from subsistence agriculture to a middle-income economy. My daughters grew up in towns that did not exist before a kimberlite pipe was discovered beneath the Kalahari.

That is not a story I tell to sell you something. It is the foundation from which I write — and the reason I believe this conversation matters.

Botswana is navigating real economic challenges today. The diamond market that built so much of what this country achieved is under genuine pressure. I believe that pressure can be eased — not by advocacy or alarm, but by the kind of clarity that helps consumers make confident decisions, restores the value conversation the industry needs, and builds a market on understanding rather than managed perception.

Letsile Tebogo runs the fastest 200 metres in the world. Amantle Montsho and Nigel Amos have stood on Olympic podiums. Katlego Pitso manages one of the most sophisticated diamond recovery plants on earth. Unami Habana is helping shape the future of Botswana’s largest diamond company. Each of them found their stage in a country that had the resources to build one.

Diamonds built that stage. The least I can do is help ensure the conversation about them is worthy of what they have made possible.

Like diamonds, truth is refined in the heat and pressure of uncomfortable debate. You are welcome here — with your questions, your scepticism and your own experience. That is where the real education begins.
