Aquamarine, the primary birthstone for March, is a gemstone deeply intertwined with the lore of the sea and a history spanning millennia. Its name, derived from the Latin “aqua marina” meaning “seawater,” aptly describes its captivating range of blue and blue-green hues. Revered for its clarity, durability, and symbolic associations with courage, happiness, and marital harmony, aquamarine continues to be a highly sought-after gem in the world of jewelry. This article will delve into the history, geological origins, gemological properties, symbolism, and care of this remarkable birthstone.
History and Lore
The history of aquamarine is rich and varied, stretching back to ancient civilizations. Pliny the Elder, a Roman philosopher and navy commander, connected the gem’s name to its resemblance to the color of the sea. Throughout history, aquamarine has been admired by numerous cultures, including the Sumerians, Egyptians, Greeks, and Hebrews. Evidence of its use dates back thousands of years, with examples found in Egyptian mummies adorned with aquamarine beads.
Ancient Greeks engraved designs into aquamarine gemstones, and Romans believed the stone could calm waves and ensure safe passage for sailors. Fishermen utilized aquamarine as a talisman for luck in catching fish and protection during voyages. Roman physicians even employed aquamarine in medicinal practices, believing it could alleviate overeating and bloating. The stone was also linked to the apostle St. Thomas, a frequent traveler by sea.
In more recent history, aquamarine became a popular choice for engagement rings, symbolizing purity and enduring love. It was considered a gift to bring happiness, constancy in marriage, and protection from conflict. The gem was also believed to empower individuals to overcome fears and gain control over their emotions, making it a favored stone for students and those engaged in intellectual pursuits. Romans associated aquamarine with Neptune, the god of freshwater and the sea, and explorers often wore it engraved with Neptune’s trident for protection against the dangers of the natural world.
Geological Formation and Sources
Aquamarine belongs to the beryl family, a group of minerals that also includes emerald and morganite. It forms in pegmatites, which are coarse-grained igneous rocks, and is created through a process involving beryllium, aluminum, silicon, and oxygen. The presence of trace elements, particularly iron, is responsible for aquamarine’s characteristic blue coloration.
Brazil is currently a primary source of aquamarine, producing significant quantities of the gem. However, deposits are also found in Nigeria, Madagascar, Zambia, Pakistan, and Mozambique. Within the United States, aquamarine can be found in Riverside and San Diego counties in California, and notably, it is the state gemstone of Colorado.
Gemological Properties
Aquamarine exhibits several key gemological properties that contribute to its desirability. It possesses a hardness of 7 on the Mohs scale, making it relatively resistant to scratching and suitable for everyday wear in jewelry. The gem’s chemical formula is Be3Al2Si6O18, reflecting its beryl composition.
The color of aquamarine can range from a greenish-blue to a pure, vibrant blue, with larger stones often displaying more intense coloration. It is important to note that aquamarine typically exhibits light color saturation and tone; darker shades of blue or green are less common. Clarity is generally good, with many aquamarines being eye-clean, meaning they lack visible inclusions to the naked eye.
Aquamarine is typically cut into a variety of shapes, including emerald cuts, oval cuts, round brilliant cuts, and pear shapes, to maximize its brilliance and showcase its color. While carat weight varies, larger aquamarines are generally more valuable, particularly those with intense color saturation.

Throughout history, aquamarine has been imbued with a wealth of symbolic meaning. As its name suggests, the gemstone is strongly associated with the sea, representing tranquility, clarity, and emotional balance. It is believed to promote courage, dispel fear, and enhance communication.
Some associate aquamarine with marital happiness and intellectual prowess. It was thought to stimulate intellect, intuition, and imagination, making it a favored stone for those engaged in learning or creative endeavors. The gem’s connection to Neptune, the Roman god of the sea, further reinforces its association with travel, exploration, and protection.
Beyond its historical symbolism, aquamarine is also believed to possess metaphysical properties. Some modern sources suggest it can help to soothe emotional turbulence, promote self-expression, and facilitate spiritual growth, though these claims are not widely accepted in formal gemology.
Care and Cleaning
Due to its relatively good hardness of 7 on the Mohs scale, aquamarine is a durable gemstone suitable for a variety of jewelry settings. However, like all gemstones, it requires proper care to maintain its brilliance and beauty.
Aquamarine can be safely cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can potentially damage the stone. It is also advisable to remove aquamarine jewelry before engaging in strenuous activities or when exposed to abrasive materials. Regular cleaning will help to remove dirt and oils, allowing the gemstone to sparkle and shine.
