As the birthstone for March 15, it is seen as a personal talisman, helping individuals achieve their goals and maintain inner peace.
Geological Formation and Sources of Aquamarine
Aquamarine is a member of the beryl family, a group of silicate minerals that also includes emerald and morganite. It is primarily composed of beryl (Be₃Al₂(SiO₃)₆), with its characteristic blue coloration derived from iron impurities within the crystal lattice. The presence of iron in different oxidation states leads to variations in the gem’s color, ranging from pale sky blue to deep, rich blue-green.
The gem is typically transparent to translucent, with a glassy luster, and is known for its high durability, ranking 7.5 to 8 on the Mohs scale of hardness. This makes it suitable for a wide range of jewelry applications, including rings, pendants, and earrings. Aquamarine is also pleochroic, meaning it can display different colors when viewed from different angles—often shifting between blue and green depending on the light and the observer’s perspective.
Aquamarine is found in granitic pegmatites and metamorphic rocks, often in association with other beryls. Major sources of high-quality Aquamarine include:
- Brazil, particularly the states of Minas Gerais and Bahia, which are among the most prolific producers of the gem.
- Colombia, where large and vividly colored Aquamarine specimens are mined.
- Nigeria, known for producing stones with a pale to medium blue color.
- Zambia, where some of the finest Aquamarine with deep blue tones is found.
- Madagascar, which has emerged as a significant source in recent decades.
Aquamarine is often heat-treated to enhance its color and clarity. This process is widely accepted in the gem trade and is not considered misleading. Heat treatment typically removes greenish tones, resulting in a more desirable sky-blue color. Untreated Aquamarine is rare and highly valued.
Gemological Properties of Aquamarine
Aquamarine’s gemological properties make it a highly desirable gemstone, both for its beauty and its resilience. Below is a detailed breakdown of its key characteristics:
| Property | Description |
|---|---|
| Chemical Formula | Be₃Al₂(SiO₃)₆ |
| Color | Light blue to deep blue-green, caused by iron impurities |
| Hardness (Mohs) | 7.5–8 |
| Luster | Vitreous (glassy) |
| Transparency | Transparent to translucent |
| Cleavage | Perfect in one direction (basal) |
| Refractive Index | 1.56–1.60 |
| Specific Gravity | 2.66–2.80 |
| Crystal System | Hexagonal |
| Common Cuts | Faceted (emerald, round, princess), cabochon |
| Treatment | Heat treatment to enhance color is common and standard in the trade |
Aquamarine is also pleochroic, meaning it can show different colors when viewed from different angles. In some stones, it may appear blue when viewed in one direction and green in another. This property is especially noticeable in rough or uncut specimens.
The best Aquamarines are those with even color, minimal inclusions, and high clarity. Stones with a vivid blue or blue-green color, especially when free from greenish or gray tones, are the most valuable. Larger stones are generally rarer and more expensive, especially if they retain their deep blue color.
Aquamarine is a popular choice for jewelry, particularly for rings, necklaces, and earrings, due to its durability and attractive color. It is also used in high-end fashion jewelry and is often paired with white gold or platinum to enhance its brilliance.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with peace, calmness, and wisdom. In ancient times, it was believed to calm the seas and protect sailors from storms. Sailors would carry Aquamarine on their voyages, believing it would guide them safely to their destinations. This belief has persisted in various cultures, where the gemstone is still considered a symbol of protection and tranquility.
In addition to its protective qualities, Aquamarine is also associated with emotional healing and balance. It is believed to soothe anxiety, reduce stress, and promote a sense of inner peace. Many people use Aquamarine in meditation practices, where it is thought to enhance intuition and psychic awareness. It is also considered a stone of communication, helping individuals express their thoughts and emotions more clearly.
In the context of birthstone symbolism, Aquamarine is associated with success, gratitude, and serenity. For those born on March 15, the gemstone is believed to amplify natural talents and bring balance to life. It is thought to support the achievement of goals and ambitions, while also encouraging a deep appreciation for the present moment.

Care and Cleaning of Aquamarine Jewelry
Due to its high hardness and durability, Aquamarine is relatively easy to care for, but it still requires some care to maintain its beauty and longevity. Here are some tips for cleaning and preserving Aquamarine jewelry:
- Avoid exposure to harsh chemicals, such as household cleaners or chlorine, as they can damage the stone's surface and clarity.
- Store Aquamarine separately from other gemstones to prevent scratches or abrasions, especially when storing in a jewelry box.
- Clean with warm, soapy water and a soft cloth or a soft-bristled brush. Avoid using ultrasonic or steam cleaners, as they can potentially damage the stone.
- Avoid extreme temperatures, as sudden temperature changes can cause thermal shock and cracking.
- Remove Aquamarine jewelry before swimming, exercising, or engaging in physical activities to prevent impact or exposure to sweat and moisture.
Because Aquamarine has perfect cleavage, it can be damaged if struck in the right direction. Therefore, it is important to handle the gem with care, especially in ring settings, where the stone is more exposed.
Regular cleaning and proper storage will help ensure that Aquamarine jewelry retains its beauty and brilliance for years to come.
