Botswana’s 2,492-Carat Diamond: A Monumental Discovery in the World of Gemstones


Botswana’s 2,492-Carat Diamond: A Monumental Discovery in the World of Gemstones


Botswana has once again solidified its position as one of the world’s premier sources of high-quality diamonds with the recent discovery of a colossal 2,492-carat diamond. This extraordinary gem, which is now the second-largest diamond ever mined, was unveiled at a ceremonial event attended by Botswana’s President Mokgweetsi Masisi. The diamond's significance is immense, both for its sheer size and its implications for the global diamond industry.



A Historic Find: The Largest Diamond in 119 Years



The 2,492-carat diamond, weighing approximately half a kilogram, is a staggering find, not only because of its size but also because it is the largest diamond discovered since 1905, when the Cullinan Diamond, weighing 3,106 carats, was unearthed in South Africa. The Cullinan Diamond, which remains the largest gem-quality diamond ever found, was cut into several major stones, some of which are part of the British Crown Jewels.

This new discovery is a testament to Botswana’s rich diamond resources, particularly the Karowe Diamond Mine, where the gem was found. Operated by Lucara Diamond Corp., a Canadian mining company, the Karowe Mine has a history of producing some of the world’s most remarkable diamonds, including the 1,758-carat Sewelo and the 1,109-carat Lesedi La Rona. The discovery of the 2,492-carat diamond further cements Karowe’s reputation as a world-class diamond mine.



The Role of Advanced Technology in Diamond Recovery



The recovery of such a massive and intact diamond would not have been possible without the advanced technology employed by Lucara Diamond Corp. In 2017, the company installed Mega Diamond Recovery (MDR) and X-ray transmission (XRT) technology at the Karowe Mine. This state-of-the-art equipment allows for the identification and preservation of large, high-value diamonds, ensuring that these extraordinary gems are recovered intact.

William Lamb, the president and CEO of Lucara, emphasized the importance of this technology in the diamond recovery process. “The ability to recover such a massive, high-quality stone intact demonstrates the effectiveness of our approach to diamond recovery and our commitment to maximizing value for our shareholders and stakeholders,” Lamb stated. He further noted that this discovery underscores the continued success of Karowe’s operational and underground development strategy.



The Economic and Social Impact of Diamond Mining in Botswana



The diamond industry is a cornerstone of Botswana’s economy, contributing significantly to the country’s GDP and providing employment to thousands of people. The discovery of such a large diamond is not just a milestone for the mining company but also a boost for the national economy. High-profile finds like this one attract global attention and can lead to increased investment in the country’s mining sector.

Moreover, the diamond industry plays a vital role in supporting livelihoods around the world. According to David Kellie, CEO of the Natural Diamond Council, the industry supports the livelihoods of 10 million people globally, providing better access to funding and resources that contribute to addressing some of the world’s most pressing challenges. This discovery, therefore, has implications far beyond the immediate financial gains, as it contributes to the broader socio-economic development of diamond-producing regions.



The Future of the Diamond Market: Innovation and Diversity



The discovery of the 2,492-carat diamond also comes at a time when the diamond industry is experiencing significant shifts. According to Grant Mobley, a diamond expert with the Natural Diamond Council, the industry has been evolving in recent years, driven by innovation and a growing emphasis on diversity. “For decades, the diamond industry operated within a traditional box, cutting diamonds in ‘safe’ ways, crafting jewelry with broad appeal, and styling it in matched sets,” Mobley explained. “In recent years, however, we’ve completely stepped out of the box, and natural diamond jewelry no longer follows strict rules.”


This shift is evident in the way diamonds are now being cut, styled, and marketed. Jewelers are increasingly experimenting with non-traditional designs, mixing metals, and layering different pieces to create unique, personalized jewelry. This trend towards customization and individuality is particularly appealing to younger consumers, who value pieces that reflect their personal style and story.


The discovery of such a large diamond in Botswana adds another layer to this narrative. Large, high-quality diamonds are rare, and each one has the potential to be cut into multiple stones that could be fashioned into a variety of innovative designs. This opens up new possibilities for jewelers and designers to push the boundaries of creativity in the industry.



The Road Ahead: Naming, Pricing, and the Diamond’s Journey



As with any significant diamond discovery, much anticipation surrounds the future of the 2,492-carat gem. The diamond has yet to be named and priced, but its size and quality suggest that it could fetch an extraordinary price at auction. For context, an 813-carat diamond from the same Karowe Mine was sold for $63 million in 2016, demonstrating the immense value that such stones can command.

Once the diamond is named and valued, the next step will likely involve decisions about how to cut and polish it. Given its size, the diamond could be split into several large stones, each with the potential to become a centerpiece of luxury jewelry collections. Alternatively, it could remain intact, preserved as a rare and historical artifact.



A Landmark Moment for Botswana and the Diamond Industry



The discovery of the 2,492-carat diamond in Botswana is a landmark event that will undoubtedly have lasting implications for the diamond industry. It reinforces Botswana’s position as a leading diamond producer and highlights the effectiveness of modern diamond recovery technology. Moreover, it comes at a time when the industry is embracing innovation and diversity, making it an exciting period for both producers and consumers.

As the world watches to see what becomes of this extraordinary gem, it is clear that the diamond’s journey—from mine to market—will be one that captures the imagination of diamond enthusiasts, investors, and the general public alike.
