The gemstones from across the Indian-Asia collisional zone, sandwiched by Kohistan-Ladakh Island Arc along the Main Karakoram Thrust possesses a variety of high quality gems. These gemstones and minerals are suture-associated, pegmatite-associated and found in hydrothermal veins. The gemstones, especially from Shigar and Hunza valleys dominantly include aquamarine, ruby, peridote, topaz, tourmaline etc. These highly valued gems need certain attention for their exploration, where the old and obsolete methodologies are still being used that abolishes the quality, quantity and worth of these gems. It also needs encouragement and proper professional training for the local people to enhance this industry environmentally and commercially.
