In which decade did diamond sources begin to emerge in South Africa?

The emergence of diamond sources in South Africa began in the 1860s, marking a significant turning point in the diamond industry. This decade is notable for the discovery of diamonds in the region, particularly with the find at the Colesberg Kopje in 1867, which initiated what would later be known as the "Kimberley Diamond Rush." This led to increased exploration and mining operations, fundamentally changing the global diamond trade and establishing South Africa as a key player in diamond production.

While earlier periods, such as the 1840s, saw some exploration and the initial allure of diamonds, the significant advancements in mining and the substantial finds that captured attention occurred mainly in the 1860s. This not only propelled South Africa to the forefront of diamond production but also created numerous economic and social impacts that shaped the region in the following years. The subsequent decades continued to see developments in the diamond mining industry, but the foundational discoveries of the 1860s were crucial in setting the stage for what was to come.
