Sierra Leone produced the third-largest gem-quality diamond in 1972. Ever since then, diamond mining has become a significant business in the country. The country is known for its mineral deposits and has relied on the mining industry for a long time. Sierra is popular for its blood diamonds that are related to the conflicts of the civil war. These diamonds were mined and exchanged for weapons during the civil war of 1991-2002. That is why the diamonds that are available from that period are referred to as conflict diamonds or blood diamonds.
