mäekristall

Mäekristall, also known as rock crystal, is a transparent and colorless variety of quartz. It is a mineral composed of silicon dioxide (SiO2) and is known for its crystalline structure. Mäekristall is found in various geological environments around the world, often forming in veins within igneous and metamorphic rocks, as well as in sedimentary rocks. Its formation typically occurs when silica-rich fluids cool and crystallize.

The purity of mäekristall can vary, with the most prized specimens being exceptionally clear and free of inclusions. These inclusions, if present, can manifest as other minerals, gases, or liquids trapped within the crystal structure during its formation. Historically, mäekristall has been valued for its aesthetic qualities and has been used in decorative objects, jewelry, and even as a material for lenses and scientific instruments due to its optical properties. It is also a popular gemstone in metaphysical and spiritual practices, often associated with clarity, energy amplification, and healing. The term "mäekristall" itself is of Germanic origin, directly translating to "mountain crystal."
