The discovery of diamonds in the\u00a0<strong>1960s<\/strong>\u00a0transformed its economy. The country has maintained stable governance and efficient management of its diamond resources, especially through its partnership with De Beers.<\/li>\n\n\n\n<li>Chile forms part of the\u00a0<strong>\u201cLithium Triangle\u201d<\/strong>\u00a0along with Argentina and Bolivia. It has some of the\u00a0<strong>largest lithium reserves in the world<\/strong>, primarily extracted from salt flats (like Salar de Atacama). Lithium is vital for batteries in electric vehicles and electronics.<\/li>\n\n\n\n<li><strong>Indonesia is the\u00a0world\u2019s largest producer of nickel<\/strong>. It holds vast reserves and has become a major player in the global nickel supply chain, crucial for\u00a0stainless steel production and electric vehicle batteries. The country has also imposed export bans to encourage domestic processing.<\/li>\n<\/ul>\n\n\n\n<h5 class=\"wp-block-heading\" id=\"diamond\"><strong>Diamond<\/strong><\/h5>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mineralogy<\/strong>: Diamond is an\u00a0<strong>allotrope of carbon<\/strong>\u00a0and the hardest naturally occurring substance on Earth.

They are primarily found in\u00a0<strong>Kimberlite<\/strong>\u00a0or\u00a0<strong>Lamproite<\/strong>\u00a0pipes.<\/li>\n\n\n\n<li><strong>Industrial vs. Gem-Quality<\/strong>: Approximately\u00a0<strong>80% of global diamond production<\/strong>\u00a0is used for industrial purposes (drilling, cutting, polishing) due to its hardness.<\/li>\n\n\n\n<li><strong>India\u2019s Global Standing<\/strong>:\n<ul class=\"wp-block-list\">\n<li>India\u00a0is the\u00a0<strong>world\u2019s largest hub for cutting and polishing<\/strong>, handling over\u00a0<strong>90%<\/strong>\u00a0of the global supply.<\/li>\n\n\n\n<li><strong>Surat, Gujarat<\/strong>\u00a0is the primary centre for this industry.<\/li>\n\n\n\n<li>Historically,\u00a0India\u00a0was the world\u2019s\u00a0<strong>only supplier<\/strong>\u00a0of diamonds for nearly 3,000 years until discoveries in\u00a0Brazil.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>India\u2019s Domestic Production<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Madhya Pradesh\u00a0is the only state in India currently producing diamonds.<\/strong><\/li>\n\n\n\n<li>The\u00a0<strong>Majhgaon Mine in Panna<\/strong>\u00a0is the only mechanized diamond mine in Asia, operated by the National Mineral Development Corporation (NMDC).<\/li>\n\n\n\n<li>Other notable Indian locations include the\u00a0<strong>Wajrakarur Kimberlite field<\/strong>\u00a0and the\u00a0<strong>Krishna River basin<\/strong>\u00a0in Andhra Pradesh.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<h6 class=\"wp-block-heading\" id=\"diamondproducing-countries\"><strong>Diamond-Producing Countries<\/strong><\/h6>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Russia:<\/strong>\u00a0The\u00a0<strong>largest producer by volume and holder of the world\u2019s largest reserves<\/strong>\u00a0(~750 million carats).
