About this subject

Aquamarine is a variety of beryl, a mineral composed of beryllium aluminum silicate. The pale blue color, characteristic of this gem, results from iron ions within the crystal lattice. It ranks 7.5 to 8 on the Mohs hardness scale, making it suitable for jewelry. Major aquamarine deposits are found in Brazil, Pakistan, Madagascar, Russia, and the United States. Brazil is one of the world's largest producers, with historic mines in Minas Gerais, Bahia, and Espírito Santo. The name "aquamarine" comes from Latin "aqua marina," meaning "seawater," reflecting its light blue hue. Crystals often form elongated hexagonal prisms and can reach considerable sizes; the largest known crystal weighed approximately 110 kg and was discovered in Minas Gerais. Pale blue aquamarine is especially prized for its transparency and delicate color, often cut in emerald or step cuts to enhance luster. Heat treatment is common to improve color by reducing greenish tones. Historically, sailors believed aquamarine protected them at sea and brought good luck. Today, it is the birthstone for March and symbolizes calm, clarity, and communication. Its beauty and durability make it a popular choice for engagement rings and fine jewelry.
