Aquamarine, the recognized birthstone for March, is a gem deeply intertwined with the lore of the sea. Celebrated for its tranquil blue hues, ranging from greenish-blue to a lighter sea-green, aquamarine has captivated cultures for millennia. As a variety of the beryl species – a close relative of the emerald – it possesses a clarity and brilliance that symbolize purity and a connection to the ocean’s depths. Beyond its aesthetic appeal, aquamarine carries a rich history of symbolism, believed to offer protection, happiness, and intellectual stimulation.
History and Lore
The name “aquamarine” itself is derived from the Latin words aqua and marina, meaning “water of the sea,” a testament to its evocative color. Ancient mariners held the gem in high regard, believing it possessed the power to calm waves and ensure safe passage. It was considered a talisman for sailors, offering protection during voyages. This association with the sea extends back to ancient times, with Roman fishermen utilizing aquamarine for good luck in their catches and safe travels by boat.
Throughout history, aquamarine has been admired by numerous civilizations. Sumerians, Egyptians, Hebrews, and Greeks all valued the gemstone. Egyptians adorned themselves with aquamarine beads, even including them in mummies, while the Greeks engraved intricate designs into the stones. 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, known for his frequent sea journeys.
Traditionally, aquamarine commemorates the 19th wedding anniversary, signifying enduring love and harmony. Beyond its association with marriage, beryl, the family to which aquamarine belongs, was historically believed to offer protection in battle and legal disputes, fostering amiability and sharpening the intellect.
Geological Formation and Sources
Aquamarine forms in granitic pegmatites, which are coarse-grained igneous rocks. The blue color is attributed to trace amounts of iron within the beryl crystal structure. The intensity of the color can vary, with larger aquamarines often exhibiting a more pronounced hue. While the gem is inherently light in tone, some exceptional stones can rival the blue of sapphire in depth.
Brazil is currently a primary source of aquamarine, yielding 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.

Care and Cleaning
Maintaining the beauty of aquamarine is relatively straightforward due to its durability. The gem can be cleaned using warm water, mild dish soap, and a soft-bristled toothbrush to remove dirt accumulation, particularly behind the setting.

Regular cleaning will help preserve the gem’s brilliance and sparkle.
Aquamarine and Bloodstone: March’s Dual Birthstones
While aquamarine is the most widely recognized birthstone for March, it shares this honor with bloodstone. Bloodstone, a dark-green cabochon speckled with red spots of iron oxide, represents health and strength. Though visually distinct from aquamarine, both stones are traditionally associated with well-being and protection. Some modern birthstone charts offer alternative gems for each month, including spinel, citrine, and tanzanite, but aquamarine and bloodstone remain the traditional choices for March. The choice between the two often comes down to personal preference, with aquamarine favored for its serene beauty and bloodstone for its grounding energy.
Conclusion
Aquamarine, the March birthstone, is a gem of captivating beauty and rich history. From its ancient origins as a talisman for sailors to its modern-day status as a symbol of tranquility and clarity, aquamarine continues to enchant and inspire. Its durable nature, combined with its stunning blue hues, makes it a cherished gemstone for jewelry and a meaningful gift for those born in March. The enduring appeal of aquamarine lies not only in its aesthetic qualities but also in the centuries of lore and symbolism that have become inextricably linked to this “water of the sea.”
