Named after the K2 mountain of Pakistan, K2 rock is exclusively found at its base. In addition to being the world’s second-highest peak (8,611 meters, or 28.250 feet), K2 mountain is one of the deadliest. It is well known for its very brutal weather, steep rock faces, and glacier climbs. For every four climbers that succeed in reaching the summit, one climber dies.
A puzzling stone, K2 rock is mainly composed of a type of Granite Gneiss, but its surface is covered with round deep blue spots. The spots have a diameter of a few millimeters to just over two centimeters. The stains on broken surfaces or slabs look like drops of bright blue paint splashed onto the rock. If you examine them closely, you’ll notice that they are actually spheres.
Its formation is covered in mystery. It is believed that a layer of copper-carbonate stained the granite below it with azurite, and occasionally malachite, probably in some epic natural events during the glacial erosion that shaped the K2 mountain.
Mostly quartz, sodium plagioclase, muscovite, and biotite, the white granite has very fine-grained crystals. Occasionally, biotite grains have a strong alignment and are considered “granite gneiss.” K2 is not Jasper, although the term ‘K2 Jasper’ is often used to market it. The rock is comprised of crystals of feldspar and specks of biotite.A closer examination of the spheres reveals that the azurite reaches into the feldspar grains as ink penetrating their boundaries. As such, azurite formed as a secondary material once all of the other minerals in the granite had solidified.
Strength and resolve.
