From the depths of the Earth to the modern jewelry market, aquamarine’s journey is as compelling as the stone itself.

History and Lore

Aquamarine has a long and storied history, often associated with maritime exploration and protection. The name "aquamarine" derives from the Latin words aqua (water) and marinus (of the sea), a fitting homage to its color and its ancient role as a talisman for sailors. According to historical accounts, mariners believed aquamarine could calm turbulent seas and protect them from drowning. These beliefs have persisted through the centuries, embedding aquamarine in the collective consciousness as a stone of serenity and safety.

In ancient times, aquamarine was also linked to the gods. The Greeks and Romans considered it a sacred stone, associating it with the god Neptune, the ruler of the seas. Some sources suggest that the stone was believed to have been formed from the tears of the sea goddess Amphitrite. This mythic origin has contributed to its enduring mystique and its symbolic connection to emotional depth and intuition—qualities strongly associated with Pisces.

The gemstone’s role as a birthstone for Pisces and March is relatively modern. While aquamarine was traditionally used in Roman times as a protective stone for travelers and sailors, its designation as a birthstone is largely a 20th-century development. The modern birthstone calendar, as we know it today, was popularized by the American National Association of Jewelers in the 1910s. Aquamarine was selected not only for its aesthetic appeal but also for its alignment with the Piscean personality—gentle, imaginative, and emotionally sensitive.

Pisces, ruled by the planets Neptune and Jupiter, is a water sign known for its dreaminess and spiritual awareness. Aquamarine’s calming blue tones are said to mirror the fluidity of water, the Piscean element. Its gentle energy is believed to enhance intuition and emotional balance, making it a fitting symbol for those born under this sign. In many modern interpretations, aquamarine is also linked to the throat chakra, further reinforcing its role in communication and emotional expression.

Geological Formation and Sources

Aquamarine is a variety of the mineral beryl, which also includes emerald. It forms in granitic pegmatites and is typically found in association with mica and quartz. The gemstone owes its striking blue color to the presence of iron impurities within its crystal structure. The intensity of the blue can vary depending on the concentration and oxidation state of the iron, with deeper, more saturated hues being the most valuable.

The formation of aquamarine requires specific geological conditions. It crystallizes under high-temperature and high-pressure conditions, often in the cavities of igneous rocks. Over time, as the rock cools and solidifies, aquamarine crystals develop, sometimes growing to impressive sizes. These conditions are rare, which makes aquamarine relatively scarce compared to other gemstones.

Geologically, aquamarine is found in several regions around the world. The most notable sources include:

Brazil: The primary source of aquamarine, particularly in the states of Minas Gerais and Bahia. Brazilian aquamarine is known for its vibrant blue color and high clarity.
Nigeria: Known for producing high-quality aquamarine, often with a deep blue color.
Zambia: Produces aquamarine with a more greenish-blue tone.
Madagascar: A growing source of aquamarine, particularly in the Anjahibe area.
United States: The state of Colorado has produced aquamarine, though in smaller quantities.

The availability of aquamarine in these regions has made it a popular gemstone in the global jewelry market. However, due to the increasing demand and limited supply, aquamarine is considered a semi-precious gemstone. This classification does not diminish its beauty or value but rather reflects its relative abundance compared to precious gemstones like diamonds, rubies, and sapphires.

Gemological Properties

Aquamarine is a remarkable gemstone with distinct gemological properties that make it both beautiful and durable. Its physical and chemical characteristics are as follows:

Chemical Formula: Be₃Al₂(SiO₃)₆ (beryl)
Hardness: 7.5–8 on the Mohs scale
Refractive Index: 1.56–1.58
Color: Ranges from pale blue to deep blue-green
Luster: Vitreous (glassy)
Transparency: Transparent to translucent
Crystal System: Hexagonal
Specific Gravity: 2.67–2.83
Cleavage: Perfect in one direction
Fracture: Uneven to conchoidal
Fluorescence: May exhibit a weak blue fluorescence under UV light

These properties make aquamarine a versatile gemstone suitable for a wide range of jewelry applications. Its relatively high hardness (7.5–8 on the Mohs scale) means it is durable enough for everyday wear, though it should still be handled with care due to its perfect cleavage. The gemstone is typically cut into brilliant or step cuts to enhance its color and brilliance. Rectangular and emerald cuts are also popular, particularly for aquamarine’s elongated crystal habit.

The gemstone’s refractive index and dispersion contribute to its optical appeal. When properly cut and polished, aquamarine displays a lively sparkle and a clear, vibrant color. The presence of inclusions is common in aquamarine, but these are often considered part of the stone’s natural character. High-quality aquamarine is characterized by its clarity, color saturation, and overall brilliance.

In terms of carat weight, aquamarine is often available in larger sizes than other gemstones. It is not uncommon to find aquamarine stones weighing several carats, making it a popular choice for statement jewelry pieces such as pendants and earrings. The combination of its durability, beauty, and availability makes aquamarine a favored gemstone for both fine and fashion jewelry.

Symbolism and Metaphysical Beliefs

Aquamarine has long been associated with a range of metaphysical properties and symbolic meanings. In ancient times, it was believed to bring protection and calmness to those who wore it. The Romans, for example, carried aquamarine as a protective talisman during sea voyages, believing it could prevent drowning and ensure safe passage. This belief has endured in various forms, with many cultures attributing protective and calming properties to the gemstone.

In modern metaphysical practices, aquamarine is considered a stone of serenity, intuition, and communication. It is believed to enhance the wearer’s ability to express themselves clearly and confidently, making it particularly beneficial for those who struggle with public speaking or self-expression. As the stone of the Pisces zodiac sign, aquamarine is also associated with emotional healing and spiritual growth. It is said to help Pisceans navigate their complex emotional landscapes and foster a deeper connection with their inner selves.

In terms of chakra alignment, aquamarine is linked to the throat chakra, which governs communication and self-expression. It is also associated with the heart and third eye chakras, further reinforcing its role in emotional and intuitive development. Those who wear aquamarine are believed to benefit from its calming energy, which can reduce anxiety, promote clarity, and enhance spiritual awareness.

Aquamarine is also thought to have protective qualities, particularly for travelers. It is often carried or worn as a talisman to provide a sense of security and to ward off negative energies. Some sources suggest that aquamarine can also help with sleep disorders and promote restful, restorative sleep. These beliefs have contributed to aquamarine’s enduring popularity in both jewelry and crystal healing practices.

In many cultures, aquamarine is also associated with love and relationships. It is believed to foster compassion, understanding, and emotional harmony between partners. This makes it a popular choice for engagement rings and other romantic jewelry pieces. The gemstone’s connection to the sea and its calming energy also make it a symbol of tranquility and lasting love.

Care and Cleaning

Due to its relatively high hardness and durability, aquamarine is a gemstone that can be worn daily with proper care. However, like all gemstones, it requires specific cleaning and maintenance practices to preserve its beauty and longevity.

Aquamarine can be cleaned using a soft brush, mild soap, and warm water. It is important to avoid harsh chemicals or abrasive cleaners, as these can damage the gemstone’s surface or weaken its structure. Ultrasonic cleaners are generally safe for aquamarine, but it is advisable to check for any inclusions or fractures that may be sensitive to vibrations.

Because aquamarine has perfect cleavage, it should be handled with care to avoid chips or fractures. It is best to store aquamarine jewelry separately from harder gemstones to prevent scratches. When not in use, it should be kept in a soft, padded jewelry box or wrapped in a cloth to protect it from impact and exposure to sunlight, which can cause the color to fade over time.

For more detailed care instructions, it is recommended to consult a professional jeweler or gemologist. They can provide guidance on the best practices for cleaning and storing aquamarine jewelry based on its specific characteristics and setting.
