Blue quartz, a member of the beryl family, is a beryllium-aluminum silicate mineral with the chemical formula Be₃Al₂(Si₂O₆)₃. It exhibits a sky-blue to blue-green hue due to the presence of divalent iron ions (Fe²⁺). It is primarily found in granite pegmatites or in the inner and outer contact zones of granite bodies associated with pegmatite activity. Major global sources include Brazil, Mozambique, and Madagascar, with the state of Minas Gerais in Brazil being one of the most renowned localities.
Blue quartz has been designated as the birthstone for March in many countries, symbolizing calmness, courage, and wisdom. It is also regarded as a symbol of happiness and eternal youth. Additionally, according to legend, it originates from the seabed as the essence of seawater. Sailors historically used it to pray for the sea god’s protection during voyages, earning it the title of the “Stone of Good Fortune.”
Blue quartz is believed to enhance expressiveness and persuasiveness, facilitating smoother communication between people.
