Pakistani K2 Gum

PAKISTANI K2 GUM STONES

Pakistan has gained a prominent position in the international market for supplying a wide variety of gemstones and mineral specimens. The northern area of Pakistan is enriched with the variety of mineral treasures that include peridot, emerald, aquamarine, tourmaline, topaz, ruby, sapphire, garnet, red spinel, pargasite, actinolite, diopside, epidote, vesuvianite, axinite, rodingite, sphene, fluorite, apatite, zircon, rutile, azurite, moonstone, amethyst, rose quartz and agate.
Northern Pakistan is composed of three lofty, snow-covered mountain ranges: Himalaya, Hindu Kush and Karakoram. These geomorphic features reflect the geological setting which, in many respects, is unique in the world. These ranges were formed as result of two collisions between India and Asia that occurred between 100 and 50 Ma (million years) ago. These collisions have induced crustal thickening in these mountains, which has resulted in metamorphism and multiple phases of deformation in these rocks. This was followed by the emplacement of leucogranites and associated pegmatites. Theses geological processes have produced a distinctive mineral kingdom within Northern Pakistan.
Most of the gemstones are pegmatite-related, such as aquamarine, tourmaline, topaz, garnet, and apatite. Some of the gemstones are hydrothermal and /or metamorphic in genesis such as emerald, ruby, sapphire, pargasite, rutile, azurite and pink topaz. The pegmatites are generally composed of feldspar (albite and microcline), quartz, biotite, muscovite and tourmaline. The important gemstones of Pakistan are listed below:
