Thank you for all your answers and i really appreciate you time and effort. may i ask you what kind of gemstones could be found in the Himalayas given that there are no proper geological minerals maps
Thats a very vague question. The Himalaya region is quite vast. Though Quartz and Aquamarine are known from the high regions of Nepal, among others...
i came across a huge deposit of garnets....just wondering what other minerals could be found in the same area
