It often occurs alongside minerals such as quartz, feldspar, and mica. Major deposits have been discovered in Brazil, Madagascar, Afghanistan, Russia, and the United States. Notable Localities: Noteworthy occurrences of aquamarine include the Santa Maria de Itabira mine in Brazil, the Shigar Valley in Pakistan, and the Mount Antero and Mount White mines in Colorado, USA. Formation: Aquamarine forms in pegmatites, which are coarse-grained igneous rocks. The mineral crystallizes in hexagonal prisms, often with well-defined terminations. The presence of iron impurities imparts the characteristic blue and blue-green colors to the crystal. Unique Features: Aquamarine is characterized by its stunning blue and blue-green colors, which can vary from pale to deep hues. The crystals typically have a hexagonal prismatic habit and may exhibit well-formed terminations. The gemstone's clarity and transparency contribute to its desirability in both the jewelry market and the world of mineral collecting.
