Aquamarine, the birthstone for March, is a captivating gemstone known for its serene blue tones that evoke the colors of the ocean and the sky. This gemstone, which derives its name from the Latin phrase aqua marina—meaning "water of the sea"—has long been cherished for its beauty, symbolism, and historical significance. While March is also associated with the bloodstone as a secondary birthstone, aquamarine stands out as the primary birthstone of the month due to its widespread appeal, relative abundance, and rich lore.
This article delves into the gemological properties, geological formation, cultural and historical significance, and practical care of aquamarine. Drawing on authoritative sources, it presents a comprehensive and expert overview for gemstone enthusiasts, jewelry collectors, and students of gemology.
History and Lore
Aquamarine has been treasured for centuries, with a history that spans ancient civilizations, maritime traditions, and medieval superstitions. The gemstone's association with the sea is particularly notable. Ancient mariners believed that carrying aquamarine would calm the waves, protect them from storms, and ensure safe passage. This belief was so deeply rooted that aquamarine was often included in the cargo of seafaring vessels as a talisman against misfortune.
In addition to its maritime associations, aquamarine was believed to bring happiness in marriage. This belief was shared by various cultures, who saw the gemstone as a symbol of love, loyalty, and harmony. The gem was also thought to grant the wearer protection against enemies in battle and litigation, suggesting a multifaceted role in both personal and public life.
Historically, aquamarine was also believed to enhance intellectual clarity and make the wearer amiable and unconquerable. These attributes made it a gemstone of choice among scholars, leaders, and warriors alike.
While aquamarine is now recognized as the birthstone for March in many cultures, its history as a symbol of protection, love, and clarity has endured through the ages.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which also includes emerald. Like emerald, aquamarine forms in granite pegmatites and metamorphic rocks. Its color is due to the presence of iron impurities in the crystal structure. The gemstone is typically found in alluvial deposits after being eroded from its primary host rocks.
The finest aquamarine is mined in Brazil, particularly in the states of Minas Gerais and Bahia. These regions are renowned for producing large, high-quality aquamarine crystals. Other notable sources include Nigeria, Zambia, and the United States, with smaller deposits found in Afghanistan, Pakistan, and Madagascar.
Aquamarine is often found in large, well-formed crystals, which are then faceted to highlight their clarity and color. The gemstone is typically free from inclusions, giving it a clear, water-like appearance that enhances its aesthetic appeal.

Aquamarine is prized not only for its beauty but also for its favorable gemological properties, which make it a durable and versatile gemstone suitable for a wide range of jewelry applications.

The most valuable aquamarine is a medium to deep blue with excellent clarity. The presence of green tones is less desirable in most markets, though some collectors appreciate these variations.
Clarity is generally excellent in aquamarine, with many stones appearing almost flawless. The absence of inclusions contributes to the gemstone’s clarity and enhances its overall beauty.
Symbolism and Metaphysical Beliefs
Aquamarine carries a rich legacy of symbolism and metaphysical beliefs that have persisted across cultures and eras. In ancient times, the gemstone was believed to promote courage, protection, and mental clarity. Sailors, in particular, revered aquamarine as a protective talisman, believing it could calm turbulent seas and ensure safe travel.
In modern times, aquamarine is often associated with serenity and emotional balance. It is believed to promote inner peace, reduce stress, and encourage honest communication. These properties make it a popular choice for those seeking emotional healing and personal growth.
Aquamarine is also linked to the throat chakra in metaphysical traditions, symbolizing the ability to express oneself clearly and truthfully. This association makes it a favored gemstone for those involved in public speaking, writing, or any form of communication.
While the scientific community does not support these metaphysical claims, the gemstone’s enduring symbolism and aesthetic appeal continue to make it a beloved choice for jewelry and personal adornment.
Care and Cleaning
Due to its relatively high hardness and stable composition, aquamarine is a durable gemstone that requires minimal care. However, to preserve its beauty and longevity, it is important to follow proper cleaning and handling practices.
Cleaning
Aquamarine can be cleaned with warm, soapy water and a soft brush. Ultrasonic and steam cleaners are generally safe to use, provided the gemstone is free from inclusions or fractures. However, it is important to avoid exposing aquamarine to extreme temperatures or sudden temperature changes, as this can cause the stone to crack or become discolored.
Storage
When not in use, aquamarine jewelry should be stored in a soft cloth or a jewelry box to prevent scratches from other harder gemstones. It is also advisable to remove aquamarine jewelry before engaging in activities that involve physical contact or exposure to harsh chemicals.
Avoiding Damage
While aquamarine is relatively tough, it can still be damaged by hard knocks or exposure to strong acids. It is best to avoid wearing aquamarine jewelry during activities that could subject it to physical stress or chemical exposure.
Aquamarine in Modern Jewelry
Aquamarine’s popularity in jewelry is due in large part to its versatile color, durability, and affordability compared to other blue gemstones such as sapphires. It is commonly used in rings, pendants, earrings, and bracelets, often set in silver, gold, or platinum.
One of the advantages of aquamarine is its availability in a range of sizes and qualities, making it suitable for both everyday wear and special occasions. Its light, refreshing color complements both warm and cool tones, making it a versatile choice for many wearers.
In the world of fashion, aquamarine has been featured in the collections of prominent jewelry designers and has been worn by celebrities and royalty alike. Its timeless appeal ensures that it remains a favored gemstone for those seeking elegance and grace.
