Goethite, named after the German polymath Johann Wolfgang von Goethe, is a common iron oxide mineral known for its earthy appearance and brown to yellow-brown coloration. It is often found in sedimentary rocks, bog deposits, and as a weathering product of other iron-bearing minerals. While not typically used in jewelry due to its relatively low hardness, goethite is valued for its use in pigments, soil amendments, and as an ore of iron. Its presence in various geological formations contributes to its importance in understanding Earth's history and processes. Additionally, goethite is associated with healing properties and is believed by some to aid in grounding and balancing energy.
