History and Lore of the March 15 Birthstone
Aquamarine’s history is deeply intertwined with the sea. The gemstone has been a symbol of maritime protection and serenity for centuries, particularly in ancient civilizations. In ancient Rome, aquamarine was believed to bring happiness to marriages and was often used in wedding rings. Sailors, too, carried aquamarine as a talisman, believing it would ensure safe passage across turbulent waters. Some sources even suggest that aquamarine was considered the treasure of mermaids, imbued with mystical powers to protect those who ventured into the ocean.
The name “aquamarine” comes from the Latin aqua marina, meaning “water of the sea,” a fitting name for a gemstone that mirrors the colors of the ocean. This connection to water is not just visual—it has also shaped the gemstone’s symbolic meaning across cultures. In medieval Europe, aquamarine was associated with fertility and health, while in some spiritual traditions, it was believed to enhance communication and intuition.
March 15 itself is a historically significant date, most famously known as the day of Julius Caesar’s assassination in 44 BCE. While this connection is often mentioned in historical discussions, it is the gemstone aquamarine that is specifically tied to the March 15 birthstone tradition. Its calming energy and protective qualities make it a fitting symbol for this date, representing both the challenges and renewal associated with the transition into spring.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which also includes the more famous emerald. It forms in igneous and metamorphic rocks under high-temperature and high-pressure conditions. The blue color of aquamarine is caused by the presence of iron (Fe³⁺) within the crystal structure. The most prized specimens are those with a pure, vivid blue color and excellent clarity.
The primary sources of aquamarine today include:
- Brazil: Known for producing some of the finest and most vibrant aquamarine specimens.
- Pakistan: A major source of aquamarine, particularly in the Hunza and Swat regions.
- Nigeria: Provides high-quality aquamarine with deep blue tones.
- Madagascar: A growing source of aquamarine, with deposits in the southern and western parts of the island.
- India: Known for producing aquamarine with a slightly greenish tint.
These deposits are mined through both large-scale and artisanal methods. The gemstone is typically cut into faceted stones or cabochons, depending on its clarity and desired use. Aquamarine is often heat-treated to enhance its color, a practice that is both common and accepted in the gemstone trade.
Gemological Properties of Aquamarine
Aquamarine is a durable gemstone, making it suitable for everyday wear. Below is a summary of its key gemological properties:
| Property | Value |
|---|---|
| Chemical Formula | Be₃Al₂(SiO₃)₆ |
| Hardness (Mohs Scale) | 7.5 – 8 |
| Color | Light blue to bluish-green |
| Refractive Index | 1.56 – 1.60 |
| Specific Gravity | 2.66 – 2.80 |
| Crystal System | Hexagonal |
| Luster | Vitreous (glassy) |
| Cleavage | Perfect in one direction |
| Transparency | Transparent to translucent |
| Common Cuts | Oval, emerald, round, pear |

Aquamarine is relatively stable and resistant to most chemicals, though it can be damaged by exposure to strong acids or bases. It is also sensitive to sudden temperature changes, so it should not be cleaned with steam or ultrasonic methods unless confirmed safe by a gemologist.
One of the unique aspects of aquamarine is its triple refraction, a property that can cause a doubling effect in the stone when viewed from certain angles. This is due to the hexagonal crystal structure and is more pronounced in certain cuts or when the stone is viewed under polarized light.
Symbolism and Metaphysical Beliefs
Aquamarine is more than just a beautiful gemstone—it carries deep symbolic and spiritual meanings. Across cultures and eras, it has been associated with a range of positive qualities, including:
- Courage: Aquamarine is often believed to instill bravery and strength, especially in those who wear it. It is considered a stone of courage for facing life’s challenges with confidence and grace.

- Tranquility and Peace: As a stone of the sea, aquamarine is linked to calmness and emotional stability. It is believed to help soothe anxiety and promote a sense of inner peace.
- Protection: Historically, aquamarine was considered a protective stone, particularly for sailors and travelers. It is still used today as a talisman for safety and good fortune.
- Healing: In some spiritual traditions, aquamarine is associated with healing properties, particularly for the throat and heart chakras. It is believed to support emotional healing and foster trust and honesty in relationships.
Astrologically, aquamarine is closely linked with the zodiac sign Pisces, which spans from February 19 to March 20. Pisces is a water sign ruled by the planet Neptune, and aquamarine’s calming energy is said to align well with the empathetic and intuitive nature of Pisces individuals.
Care and Cleaning of Aquamarine
Proper care is essential to maintaining the beauty and longevity of aquamarine jewelry. Here are some key tips for cleaning and storing aquamarine:

- Avoid Extreme Temperatures: Aquamarine can be sensitive to sudden temperature changes, so avoid exposing it to extreme heat or cold.
