The Banankoro Diamond Mines are the epicenter of Guinea's gemstone industry, located in the Kérouané Prefecture. The region is globally renowned for its rich alluvial diamond deposits found within the sediments of the Baoulé River and its tributaries. Mining in Banankoro is a blend of large-scale industrial concessions and intensive artisanal mining. Thousands of miners, known as 'orpailleurs,' work under often challenging conditions to wash precious stones from river gravel. Geographically, the area is characterized by a hilly landscape with fertile valleys and winding riverbeds. Economically, the Banankoro mines are the most critical factor for prosperity in eastern Guinea, though they have fostered a volatile economic structure heavily dependent on global diamond prices. Banankoro diamonds are prized for their high quality and clarity. The mines have turned the town of Banankoro into a bustling commercial hub attracting buyers from around the world. Despite the wealth generated, the region faces significant challenges, including environmental degradation from unregulated mining and the need for better social protections for the mining community.
