Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which is a silicate of beryllium and aluminum. Its chemical formula is Be₃Al₂(SiO₃)₆, and it belongs to the hexagonal crystal system. The gemstone’s signature blue color is due to the presence of iron impurities within the crystal structure. The intensity of the blue can vary depending on the concentration of these impurities, resulting in a range of shades from pale, almost colorless blues to rich, deep oceanic hues.
Aquamarine is typically found in granitic pegmatites, which are igneous rocks that form under high-pressure and high-temperature conditions. These environments allow for the slow crystallization of minerals, resulting in the large, well-formed crystals that are characteristic of beryl. The gemstone is also occasionally found in metamorphic rocks, though these occurrences are less common.
The largest and most renowned deposits of aquamarine are found in Brazil, particularly in the states of Minas Gerais and Bahia. Brazil has long been the primary source of aquamarine for the global market, producing some of the finest and most valuable specimens. Other notable sources include Pakistan, China, Myanmar, Russia, and Ukraine. These countries have also contributed to the supply of aquamarine, though in smaller quantities compared to Brazil.
In recent years, Africa has emerged as a new source of aquamarine. Mines in Mozambique, Kenya, Madagascar, Zambia, and Nigeria have produced high-quality aquamarine, adding to the global supply. These African deposits are particularly significant because they offer an alternative to traditional sources and help ensure a more sustainable and diverse supply chain.
In the United States, aquamarine can be found in the Mount Antero area of Colorado and in southern California. These domestic sources, while not as prolific as those in Brazil or Africa, provide an important local supply and contribute to the gemstone’s accessibility for American jewelers and consumers.
Aquamarine is known for its durability, with a hardness of 7.5 to 8 on the Mohs scale. This makes it suitable for use in a variety of jewelry, including rings, earrings, and pendants. The gemstone also has an imperfect cleavage and a vitreous luster, which contribute to its overall brilliance and visual appeal.
One of the unique properties of aquamarine is its optical characteristics. It is uniaxial negative, meaning that it exhibits a single optic axis. Some specimens may also display strong dichroism, where the stone appears to have different colors when viewed from different angles. This property adds to the gemstone’s visual complexity and makes each aquamarine unique.
Inclusions are common in aquamarine and can include mica, hematite, and liquid-filled tubes or hoses. These inclusions are often considered part of the gemstone’s character and are not viewed as flaws. However, excessive inclusions can affect the clarity and value of the stone. It is important to note that aquamarine can be sensitive to heat, as the liquid inclusions may expand and cause the stone to fracture or even explode under high temperatures.
Aquamarine is also known for its transparency, with high-clarity specimens being highly valued in the jewelry market. Unlike emerald, another variety of beryl, aquamarine is more commonly found in high-clarity, fracture-free form, making it more affordable and accessible for a wider range of consumers. This abundance of high-quality material has contributed to aquamarine's popularity as a birthstone and as a gemstone for everyday wear.
