K2 Stone is a unique and rare stone that is found exclusively on the K2 mountains of Pakistan. It is a form of Granite Gneiss that contains spherical, bright blue spots that are riddled all over. The stone is named after the K2 mountains and is also known as "Blue Berry Jasper". The K2 mountains are an extremely remote area of the world, making the stone even more valuable and unique. The stone is a great addition to any rock lover's collection and is definitely a one-of-a-kind piece of mysterious geologic history. The bright blue spots on the K2 Stone are caused by weathering and erosion brought on by glaciers that carved the K2 mountains. A now "erased" layer of copper-carbonate rich stratigraphic layer only left its mark by staining the Granite below it. The Azurite and sometimes Malachite occurrence is the result of the copper-carbonate rich stratigraphic layer being stained by the Granite below it. The K2 Stone is a unique and rare stone that is not only visually appealing but also has a rich history. It is a great addition to any rock lover's collection and is sure to impress with its unique and rare appearance.
