FELDSPAR (FLUORESCENT)

Feldspar is one of the most abundant minerals in the Earth’s crust, comprising a group of rock-forming minerals that are essential components of igneous, metamorphic, and sedimentary rocks. Feldspar minerals typically exhibit a range of colors, from white, gray, and pink to red, green, and even blue, depending on their chemical composition. The group includes well-known varieties such as orthoclase, microcline, and plagioclase, each of which has unique structural and chemical properties.
