Aquamarine, the captivating birthstone for March, embodies the serenity and renewal associated with the transition from winter to spring. Revered for its tranquil blue to blue-green hues, reminiscent of the ocean’s depths, this gemstone has held a significant place in history, lore, and modern jewelry. This article will delve into the geological origins, gemological properties, historical significance, and symbolic meanings of aquamarine, providing a comprehensive overview of this cherished gem.
History and Lore
The name “aquamarine” itself offers a glimpse into the stone’s historical connection to the sea. Derived from the Latin words aqua (water) and marina (of the sea), the name directly references its color. Ancient mariners believed aquamarine possessed protective qualities, claiming the gem could calm waves and ensure a safe voyage. It was carried as a talisman for good luck and protection against the perils of the ocean. Beyond seafaring, beryl – the mineral family to which aquamarine belongs – was historically believed to offer protection against foes in battle and litigation, fostering amiability and quickening the intellect.
Aquamarine’s association with happiness in marriage is also deeply rooted in tradition. Throughout history, the gem has been exchanged as a gift to ensure a lasting and joyful union. Today, aquamarine is traditionally given as a gift to celebrate a 19th wedding anniversary, continuing this legacy of love and commitment.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with its color stemming from trace amounts of iron within its crystalline structure. The gem typically forms in pegmatite veins, which are coarse-grained igneous rocks formed during the final stages of magma crystallization. These veins provide the ideal environment for the growth of large, well-formed aquamarine crystals.
Several locations around the world are known for their aquamarine deposits. Brazil is a particularly significant source, with Brazilian Santa Maria aquamarine being among the most valuable varieties. Other notable sources include Madagascar, Nigeria, and the United States. While historically, aquamarines with a green tint were highly valued, modern preferences lean towards vivid, sky-blue specimens.
Gemological Properties
Aquamarine boasts a range of impressive gemological properties that contribute to its beauty and durability. It registers between 7.5 and 8 on the Mohs hardness scale, making it suitable for everyday wear in jewelry, including rings. Its chemical composition is Be₃Al₂Si₆O₁₈, classifying it within the beryl family alongside emerald and morganite.
The gemstone is typically transparent to translucent, exhibiting a vitreous luster that enhances its brilliance. Aquamarine’s refractive index falls between 1.567 and 1.590, contributing to its sparkle and fire. A notable characteristic of aquamarine is its pleochroism, meaning it can display different colors when viewed from different angles. This phenomenon adds depth and complexity to the gem’s appearance.
The color of aquamarine ranges from light blue to blue-green, with the most prized specimens displaying a deep, intense blue hue. While lighter shades are more common, darker tones can rival the blue of sapphire in their vibrancy. Aquamarine’s clarity is also highly valued, with stones free from inclusions being particularly sought after.

The gem is believed to promote clear communication and reduce stress, fostering inner peace and tranquility.
Aquamarine’s connection to the sea extends beyond its name and historical use by sailors.

Some believe it enhances communication, making it an ideal stone for those who struggle to articulate their thoughts and feelings. The stone is thought to inspire the wearer to be truthful and authentic, fostering genuine connections with others.
Care and Cleaning
Due to its relatively high hardness, aquamarine is a durable gemstone suitable for various jewelry settings. However, like all gemstones, it requires proper care to maintain its brilliance. 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 store aquamarine jewelry separately from other gemstones to prevent scratching. Regular cleaning will help remove dirt and oils, ensuring the gem continues to sparkle and shine. Given its durability, aquamarine is well-suited for both everyday wear and special occasions.
