Mineral Name: Aquamarine Chemical Formula: Be3Al2(SiO3)6 - Beryllium Aluminum Silicate Color: Aquamarine is renowned for its stunning blue to blue-green hues, reminiscent of the clear waters of the ocean. The color is attributed to trace amounts of iron within the crystal structure. Crystal System: Hexagonal Hardness: 7.5 - 8 on the Mohs scale Luster: Vitreous Transparency: Transparent to translucent Specific Gravity: 2.68 - 2.74 Cleavage: Indistinct Fracture: Conchoidal Streak: White Occurrences: Aquamarine is commonly found in granite pegmatites, where it forms as a result of hydrothermal processes involving beryllium-rich fluids. It often occurs alongside minerals such as quartz, feldspar, and mica. Significant 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 hexagonal crystal structure of aquamarine leads to the development of well-formed prismatic crystals with flat terminations. The presence of iron impurities imparts the characteristic blue and blue-green colors to the crystal. Unique Features: Aquamarine is characterized by its captivating blue and blue-green colors, reminiscent of the calming shades of the sea. The crystals often have a hexagonal prismatic habit, and gem-quality specimens are prized for their clarity and transparency.
