Editor’s Note
This article explores the Kimberley Mine, known as the “Big Hole,” a pivotal site in South Africa’s diamond history that helped shape the modern global diamond industry.

The Kimberley Mine, located in the heart of Kimberley, South Africa, is one of the most significant landmarks in global diamond mining history. Known globally as the Big Hole, this massive excavation site has not only shaped the mineral trajectory of the region but has also laid the cornerstone for the development of the modern diamond sector.
Discovered in the late 19th century, the Kimberley Mine triggered the first major diamond rush globally, transforming South Africa into a key player in the minerals sector. Essentially a massive hand-dug pit, the mine reaches depths of 200 meters, spans approximately 17 hectares, and began a global reckoning with large-scale resource extraction. Over decades, it produced millions of carats—culminating in over 14 million carats—fueling the foundation of prominent companies like De Beers. The site is now a protected heritage attraction, symbolizing the wealth and industrial prowess of South Africa. Its historic significance continues to capture the imagination of both the jewellery community and tourists worldwide.
The Kimberley diamond hole refers to the crater left behind after years of intensive diamond extraction. Today, it stands as an iconic heritage site, drawing visitors interested in the industrial and geological history of the diamond industry. This big hole is not just a remnant of the past, but a testament to the enduring legacy and the lessons learned about technological progress and environmental management.
Geologically, the Kimberley diamond hole is remarkable. This kimberlite pipe beneath the earth’s surface is the primary source of diamonds worldwide. It remains an essential model for:
• Geologists investigating volcanic pipe formations and their implications for mineral extraction.
• Scientists seeking insights into the mantle and tectonic activity beneath the earth.
• Industrial engineers pursuing new methods for resource management and environmental reclamation.
This site not only produced diamonds but also served as a global benchmark for efficient extraction and innovative mining processes, marking the transition from hand-dug to mechanized operations. The lessons learned in Kimberley underpin much of today’s thinking about sustainable mining technologies.
While the historical capacity of Kimberley was rooted in extraction, the modern focus extends far beyond raw mining. Today, Kimberley’s diamond sector is undergoing a renaissance—championing value addition, sustainable practices, and entrepreneurship. At the heart of this movement stands the Kimberley diamond and jewellery incubator, bridging past, present, and future. Let’s explore the incubation model redefining empowerment, innovation, and sustainable growth within South Africa’s diamond industry.
| Year/Era | Diamond Output (carats, est.) | Employment (jobs, est.) | Sustainable Practices Adopted | Local Jewellery Startups Supported | Economic Impact (R million, est.) |
|---|---|---|---|---|---|
| Peak Historical (c. 1900) | 1,300,000 | 11,000 | ❌ (Minimal) | – | 2,000+ |
| Present Day (2024) | 12,000 | 2,000 | ✓✓ (High) | 1,500+ | 5,500+ |
| Projected (2026) | 13,500 | 2,200+ | ✓✓✓ (Advanced) | 2,000+ | 6,200+ |
This table highlights the remarkable evolution of the diamond industry in Kimberley, tracing historic output through to a modern, innovation-driven, sustainable future led by initiatives like the Kimberley diamond and jewellery incubator.
The Kimberley diamond and jewellery incubator embodies a new vision for South Africa’s diamond ecosystem. Rather than focusing solely on raw extraction, the incubator is centered on skills development, entrepreneurship, and sustainable value addition.
