Aquamarine, with its serene blue to blue-green hues, stands as the primary birthstone for those born on March 17th. This gemstone, whose name derives from the Latin words aqua (water) and marina (sea), embodies the calm of the ocean and the refreshing qualities of spring. As a member of the beryl family, which also includes emeralds, aquamarine possesses not only remarkable gemological properties but also a rich tapestry of historical lore and cultural symbolism. For centuries, it has been revered as a talisman of protection, a stone of emotional balance, and a symbol of clarity and courage. This article provides a comprehensive exploration of aquamarine, detailing its historical journey, geological origins, scientific characteristics, and enduring significance as the March 17th birthstone, drawing exclusively from authoritative sources to present an expert guide for gemstone enthusiasts, collectors, and students of gemology.
History and Lore
The historical significance of aquamarine is deeply intertwined with human fascination for the sea. Its name is a direct reflection of its most prized coloration, evoking the tranquil waters of the ocean. Ancient civilizations, particularly those with strong maritime traditions, held aquamarine in high esteem. In ancient Greece, the stone was believed to be a divine gift from Poseidon, the god of the sea. This association imbued aquamarine with a powerful protective reputation. Greek sailors would often carry aquamarine amulets or wear jewelry set with the gem, believing it would grant them safe passage across treacherous waters and protect them from the perils of the sea. This belief in its protective qualities extended beyond physical safety to emotional and spiritual realms, with the stone being associated with calm, tranquility, and courage in the face of adversity.
The lore surrounding aquamarine's protective properties was not confined to ancient Greece. Across various cultures, the gemstone was thought to shield its wearer from negative energies and promote a sense of inner peace. Many believed that aquamarine possessed healing properties, capable of calming a turbulent mind, soothing emotional distress, and bringing clarity to one's thoughts. This belief in its ability to promote emotional balance and mental clarity has persisted through the centuries, contributing to its enduring appeal.
The journey of aquamarine to becoming a modern birthstone is part of a broader historical evolution. Traditional birthstone lists often have roots in biblical references, such as the gemstones on Aaron's breastplate or the foundation stones of the New Jerusalem. Over time, these lists were adapted and formalized. The modern standardized birthstone list, which solidified aquamarine's status as a March birthstone, was largely influenced by a 1912 list created by the National Association of Jewelers in the United States. While March is traditionally associated with two primary birthstones—aquamarine and bloodstone—aquamarine is widely recognized as the primary and most popular choice, especially for its connection to the serene qualities of early spring. For individuals born on March 17th, aquamarine holds a particular significance, serving as a personal gemstone that connects them to the season of renewal and the symbolic properties of wisdom and tranquility.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with the chemical formula Be₃Al₂Si₆O₁₈. Its characteristic blue to blue-green coloration is primarily caused by trace amounts of iron within its crystal structure. The gemstone forms in pegmatites, which are coarse-grained igneous rocks. These environments provide the necessary conditions for the slow crystallization of large, high-quality aquamarine crystals, which can sometimes be found in exceptional sizes suitable for cutting into significant gemstones.
While aquamarine deposits are found in several locations worldwide, certain regions are particularly renowned for producing gems of superior quality and size. Historically, Brazil has been a primary source for large, high-quality aquamarine crystals. Other notable sources include Pakistan, Mozambique, Nigeria, and Madagascar, each contributing to the global supply of this cherished gemstone. The specific geological conditions in these regions allow for the formation of aquamarine with varying shades of blue, from the very pale, almost colorless varieties to the more intensely saturated "Santa Maria" blue, a term used to describe a deep, vivid blue aquamarine originally associated with mines in Brazil's Santa Maria de Itabira region.
The mining of aquamarine often involves both artisanal and small-scale operations, as well as larger commercial endeavors. The gemstone is typically extracted from hard rock, requiring careful excavation to avoid damaging the crystals. Once mined, the rough crystals are sorted and assessed for their potential to be cut into fine gemstones. The largest and most flawless crystals are reserved for high-end jewelry, while smaller or included stones may be used for more affordable pieces or carved into decorative objects.
Gemological Properties
Aquamarine possesses a set of gemological properties that make it a durable and attractive choice for jewelry. Its physical characteristics are well-documented and contribute to its popularity among jewelers and consumers alike. The following table summarizes the key gemological properties of aquamarine, based on established gemological standards.
| Property | Value / Description |

| Typical Inclusions | Liquid inclusions, two- and three-phase inclusions, mineral inclusions (e.g., mica), growth lines, and feathers. |
The hardness of aquamarine, ranging from 7.5 to 8 on the Mohs scale, makes it resistant to scratching and suitable for everyday wear in rings, earrings, and pendants. This durability is a key factor in its preference as a birthstone for jewelry. Its vitreous luster gives it a bright, reflective surface, enhancing its visual appeal. While aquamarine is generally found in lighter shades, heat treatment is a common and accepted practice in the gem trade to remove unwanted yellow or green tints, resulting in a more desirable blue color. This treatment is stable and does not affect the stone's durability or value when properly disclosed.
Symbolism and Metaphysical Beliefs
Beyond its physical beauty, aquamarine is rich in symbolic meaning and metaphysical beliefs. Its primary symbolism is linked to water and the sea, representing tranquility, peace, and emotional balance. As a stone of courage, it is believed to help its wearer overcome fear and anxiety, promoting a calm and clear state of mind. In many metaphysical traditions, aquamarine is associated with the throat chakra, which is linked to communication and self-expression. It is thought to aid in speaking one's truth with clarity and compassion.
The calming energy of aquamarine makes it a popular choice for meditation and spiritual practices. It is believed to facilitate a connection with the intuitive and subconscious mind, enhancing spiritual awareness. Some traditions also attribute protective qualities to aquamarine, viewing it as a shield against negative energies and psychic attacks. These beliefs, while not scientifically proven, have contributed to the stone's enduring cultural significance and its use as a personal talisman.
For those born on March 17th, aquamarine serves as a birthstone that embodies these symbolic traits. It is seen as a guide for navigating life's challenges with wisdom and emotional resilience, aligning with the introspective and compassionate nature often associated with individuals born in early spring.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of aquamarine jewelry. Given its good hardness, aquamarine is relatively durable, but it is not indestructible. It is important to handle it with care to avoid damage from sharp blows or pressure, which could cause fractures or chipping, especially if the stone has natural inclusions or feathers.
For cleaning aquamarine, warm water, mild soap, and a soft brush are recommended. A soft cloth or a soft-bristled brush can be used to gently scrub the gemstone and remove any dirt or debris. After cleaning, the gemstone should be rinsed thoroughly with warm water and dried with a soft, lint-free cloth. It is crucial to avoid using ultrasonic cleaners or steamers, as these can cause damage to the gemstone. Aquamarine is sensitive to heat and sudden temperature changes, so it should not be exposed to direct sunlight or hot water for extended periods, as this could potentially alter its color or cause damage.
For storage, aquamarine should be kept separately from other gemstones in a soft cloth or jewelry box to prevent scratches. It is advisable to avoid wearing aquamarine during physical activities or when handling harsh chemicals, as this can increase the risk of damage. Aquamarine is also sensitive to shock and impact, so it is important to handle it with care. When not in use, it should be stored in a dry, cool place to preserve its color and clarity. By following these care instructions, owners can ensure that their aquamarine jewelry remains a beautiful and meaningful heirloom for generations.
