The economy of Sakha mostly relies on the mining of minerals like diamonds, gold, tin and coal. It is the region's largest producer of minerals and raw materials. Sakha also produces 99% of Russia's diamonds. This accounts for about 25% of the world's diamond output. The making of construction materials, jewellery and medicine are also major industries in Sakha. In contrast, the native Yakut people rear cattle and horses or hunt and fish to provide for themselves as well.
