For those born on March 15, the birthstone is aquamarine, a gemstone celebrated for its tranquil blue hues and its rich historical and symbolic significance. Known as the "water of the sea" in Latin, aquamarine evokes the calming essence of the ocean and has long been associated with serenity, courage, and protection. This article explores the geological origins, cultural lore, gemological properties, and modern relevance of aquamarine, the March 15 birthstone, drawing from a range of expert and historical sources.
Historical Significance and Lore
Aquamarine’s history is deeply intertwined with maritime traditions and ancient beliefs. The gemstone was revered by ancient civilizations, particularly in its role as a protective talisman for sailors. Roman mariners believed that carrying aquamarine ensured calm seas and safe voyages. The stone was also thought to bring happiness in marriage and was valued for its calming properties. In medieval Europe, aquamarine was linked to fertility and general well-being, reinforcing its reputation as a stone of health and harmony.
The name "aquamarine" comes from the Latin aqua marina, meaning "sea water," a fitting description of its color, which ranges from light blue to bluish-green. Ancient cultures also believed that the gem was the treasure of mermaids and carried mystical powers that safeguarded those at sea. In addition to its protective qualities, aquamarine was thought to enhance intuitive abilities and promote clear communication, making it a favored stone among spiritual seekers and healers.
March 15 also carries historical weight, as it was on this day in 44 BC that Julius Caesar was assassinated. While no direct connection is drawn between aquamarine and this event in the sources, the date’s historical significance underscores the gemstone’s enduring legacy in both cultural and symbolic contexts.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which is composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆). Its blue color is due to the presence of trace amounts of iron within the crystal structure. The gemstone forms in igneous rocks, particularly in granite pegmatites, where it grows in large, well-formed crystals. These conditions allow for the development of large, clear stones that are often free of inclusions.
Significant sources of aquamarine include Brazil, Madagascar, Nigeria, and the United States. Brazil is particularly renowned for producing high-quality aquamarine, including the famous 1936 gift to Eleanor Roosevelt, a 1,298-carat rectangular step-cut aquamarine presented by the government of Brazil. These deposits are found in regions such as Minas Gerais, where geological conditions are ideal for the formation of large, gem-quality crystals.
Aquamarine is typically found in light blue to sea-green hues, with the most valuable stones exhibiting a pure, even blue coloration. The gemstone is generally free from inclusions and has a clarity that resembles water, symbolizing purity and clarity of thought. These characteristics make aquamarine a highly sought-after gemstone in both historical and modern jewelry contexts.
Gemological Properties
Aquamarine is a durable gemstone, with a hardness of 7.5 to 8 on the Mohs scale, making it suitable for everyday wear in jewelry. It is also relatively stable, with a refractive index of 1.57 to 1.58, and a specific gravity of approximately 2.67 to 2.80. These properties contribute to its brilliance and durability, making it ideal for use in rings, pendants, and earrings.
The gemstone is typically cut in a brilliant or step cut to enhance its clarity and color. Aquamarine is also known for its pleochroism, a property that allows it to display different colors when viewed from different angles. This effect adds to its visual appeal and makes it a unique and captivating gemstone.
As a beryl variety, aquamarine is also known for its excellent transparency and its ability to be faceted into large, well-proportioned stones. It is generally free of inclusions, making it a preferred choice for high-quality jewelry. The gemstone is often treated to enhance its color, although untreated aquamarine is highly valued by collectors and gemologists.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with serenity, courage, and protection. In ancient times, it was believed to be a protective stone for sailors and those embarking on long journeys. This association with the sea and travel has endured through the centuries, with aquamarine continuing to be regarded as a stone of calm and safety.
In addition to its protective qualities, aquamarine is believed to promote emotional balance and inner peace. It is associated with the throat chakra and is thought to enhance communication and self-expression. Many spiritual practitioners and healers use aquamarine for its calming effects and its ability to dispel fear and anxiety.
Aquamarine is also linked to the zodiac sign of Pisces, which spans from February 19 to March 20. As the Piscean birthstone, it is believed to support emotional sensitivity, intuition, and spiritual growth. This connection reinforces its use in jewelry and spiritual practices, particularly among those born under the sign of Pisces.
The gemstone is also associated with the 19th wedding anniversary, symbolizing the deep, enduring bond between partners. It is believed to bring clarity to relationships and promote mutual understanding and harmony.
Care and Maintenance
Due to its relatively high hardness on the Mohs scale, aquamarine is a durable gemstone that can withstand daily wear. However, it is still important to care for aquamarine jewelry properly to maintain its beauty and longevity.
Aquamarine should be cleaned using a soft, lint-free cloth and mild soapy water. Ultrasonic and steam cleaners can be used for cleaning, but care should be taken with any inclusions or fractures in the stone, as these can be sensitive to vibration and heat. Avoid using harsh chemicals or abrasive materials, as these can damage the gemstone or its setting.
When storing aquamarine jewelry, it should be kept in a separate compartment or wrapped in a soft cloth to prevent scratches. It is also advisable to avoid exposing the gemstone to extreme temperatures or sudden temperature changes, as this can cause stress and potentially lead to fractures.
For more elaborate pieces, such as antique or custom jewelry, professional cleaning and inspection are recommended to ensure the stone and setting remain in optimal condition.
Aquamarine in Modern Jewelry
Aquamarine continues to be a popular gemstone in modern jewelry design, appreciated for its beauty, symbolism, and versatility. It is commonly used in rings, pendants, earrings, and bracelets, often paired with diamonds or other white gems to enhance its clarity and brilliance. The gemstone is also popular in engagement rings and anniversary gifts, particularly for March birthdays and the 19th wedding anniversary.
Designers often highlight aquamarine’s natural color by using simple, elegant settings that allow the gemstone to take center stage. The gemstone’s transparency and light blue hue make it a perfect choice for vintage-inspired and contemporary designs alike. In recent years, aquamarine has also gained popularity in minimalist and bohemian jewelry styles, where its serene color and subtle elegance are highly valued.
Aquamarine is also used in alternative healing practices and spiritual jewelry, where it is believed to promote inner peace and emotional balance. It is often incorporated into chakra jewelry and meditation tools, reflecting its enduring metaphysical significance.

Aquamarine’s symbolism extends beyond its physical properties and into the realm of cultural and spiritual meaning. It is often associated with the ocean, reflecting themes of calm, clarity, and renewal. In many cultures, the gemstone is seen as a symbol of hope and renewal, particularly during times of transition or uncertainty.
The gemstone’s connection to March and the arrival of spring further enhances its symbolic significance.
