Maybe they do but I seriously doubt if the money from all those semi-precious gemstones would go into any other pockets than those of the few families who are already obscenely wealthy, powerful and well-connected.

https://en.wikipedia.org/wiki/Tourmaline
Tourmaline (/ˈtʊərməliːn/ toor-mə-leen) is a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone comes in a wide variety of colors. The name comes from the Tamil and Sinhalese word "Turmali" (තුරමලි) or "Thoramalli" (තෝරමල්ලි), which applied to different gemstones found in Sri Lanka.
It’s the rare earth metals/minerals the Afghans are sitting on that has everybody taking a swing at extracting.
