Additionally, we will provide practical advice on how to care for aquamarine, ensuring it retains its brilliance for generations to come.
History and Lore
Aquamarine has captivated human imagination for centuries, with its name derived from the Latin words aqua (water) and marina (of the sea), a fitting description of its tranquil hues. The gemstone has long been associated with the sea and the protection of sailors. In ancient times, aquamarine was considered one of the most valuable and sacred stones, often used in royal jewelry and as a talisman for safe travels.
The Roman philosopher and navy commander Pliny the Elder wrote about aquamarine, noting that it was believed to have been formed in the sea and washed ashore with waves. He described it as "the green of the sea," and this description has persisted in gemological literature. Romans held aquamarine in high esteem, linking it to Neptune, the god of the sea. It was often engraved with Neptune’s trident and worn by travelers and explorers for protection against the unknown dangers of the natural world.
Throughout history, aquamarine has also been a symbol of purity and emotional balance. In medieval Europe, it was used in engagement rings, believed to promote constancy and happiness in marriage. The stone was also worn by scholars and those engaged in deep study, as it was thought to stimulate intellect, intuition, and imagination. This belief persists in some metaphysical traditions today.
The modern association of aquamarine with March is rooted in historical birthstone lists, which date back to the 1st century AD. These lists, originally based on the 12 stones of Aaron’s breastplate and the foundation of New Jerusalem, were later adapted to align with the 12 months of the year and the zodiac signs. By the 18th and 19th centuries, standardized birthstone lists began to emerge, with aquamarine firmly established as the birthstone for March.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, which also includes emerald as one of its most famous forms. The difference between aquamarine and emerald lies primarily in the trace elements that give each stone its characteristic color. While emerald owes its deep green color to chromium or vanadium, aquamarine gets its blue and blue-green tones from iron. This makes aquamarine a lighter, more transparent stone compared to emerald.
Beryl is formed in igneous rocks, typically in pegmatites—coarse-grained igneous rocks that form from the slow cooling of magma. These geological conditions allow for the growth of large, well-formed crystals, which is why aquamarine can be found in significant sizes, sometimes weighing hundreds of carats. Aquamarine is also occasionally found in metamorphic rocks, though less commonly.
The finest aquamarine is found in several parts of the world, with Brazil being the most notable source. The country is home to some of the largest and most beautiful aquamarine deposits, particularly in the states of Minas Gerais and Bahia. Other important sources include Nigeria, Zambia, the United States (especially California), and more recently, Afghanistan and Pakistan. Each of these regions produces aquamarine with slightly different characteristics, such as variations in color intensity and clarity.
Aquamarine is typically faceted to showcase its clarity and color, as it is a transparent gemstone. The faceting process enhances its brilliance and allows the light to refract through the stone, creating a dazzling display of color. The stone's hardness on the Mohs scale ranges from 7.5 to 8, making it durable enough for everyday wear, though it is still susceptible to damage from hard knocks or exposure to harsh chemicals.
Gemological Properties
Aquamarine is a gemstone of remarkable beauty and durability, with a range of physical and optical properties that make it a favorite among gemologists and jewelers alike. The following table summarizes its key gemological characteristics:
| Property | Value |
|---|---|
| Chemical Formula | Be₃Al₂(SiO₃)₆ |
| Crystal System | Hexagonal |
| Hardness (Mohs) | 7.5 to 8 |
| Color | Blue to blue-green (due to iron impurities) |
| Refractive Index | 1.56 to 1.60 |
| Specific Gravity | 2.66 to 2.83 |
| Cleavage | Perfect in one direction (basal) |
| Luster | Vitreous (glassy) |
| Transparency | Transparent to translucent |
| Common Cuts | Round brilliant, emerald, pear, and oval |
These properties make aquamarine an ideal gemstone for a variety of jewelry applications, including rings, necklaces, and earrings. Its clarity and color make it particularly well-suited for showcase pieces, and its relative hardness ensures that it can be worn daily without excessive risk of damage.
One of the most notable aspects of aquamarine is its color range, which can vary from a pale, almost colorless blue to a deep, rich blue-green. The most valuable aquamarines are those with a strong, even blue color and excellent clarity. Stones with a more greenish hue are generally less valuable, as the blue tones are considered more desirable.
Aquamarine is also known for its pleochroism, a property that allows the stone to display different colors when viewed from different angles. In some cases, aquamarine may appear greenish when viewed from one direction and bluish from another. This effect is subtle and not always noticeable, but it adds to the stone's visual complexity.
Symbolism and Metaphysical Beliefs
Aquamarine has long been associated with a wide range of symbolic and metaphysical meanings. In many cultures, it is seen as a stone of calm, clarity, and emotional balance. Its connection to the sea has led to beliefs about its protective powers, particularly for sailors and travelers. In ancient times, aquamarine was worn to ensure safe passage across the oceans and to protect against the dangers of the sea.
In medieval Europe, aquamarine was believed to promote constancy and happiness in marriage, which is why it was sometimes used in engagement rings. It was also associated with the protection of children and the promotion of good health. The stone was thought to have a calming effect on the mind and body, helping to reduce stress and anxiety.
In modern metaphysical traditions, aquamarine is still revered for its calming properties. It is often used in meditation to help promote mental clarity and emotional stability. Some believe that aquamarine can enhance communication and encourage truthful self-expression. It is also thought to be a protective stone, shielding the wearer from negative energies and promoting a sense of inner peace.
In some cultures, aquamarine is associated with the throat chakra, which is believed to govern communication and self-expression. Wearing aquamarine is thought to help individuals speak their truth with confidence and clarity. This belief has contributed to the stone’s popularity in jewelry, particularly in pendants and rings that are worn close to the body.
Care and Cleaning
Given its hardness and durability, aquamarine is a relatively easy gemstone to care for, but it does require some special attention to maintain its beauty and longevity. The following are some best practices for cleaning and maintaining aquamarine jewelry:
Cleaning
- Warm, Soapy Water: A gentle cleaning solution of warm water and mild dish soap is generally sufficient for cleaning aquamarine. Use a soft cloth or a soft-bristled brush to gently scrub the stone and remove any dirt or debris.
- Ultrasonic Cleaners: Aquamarine is generally safe to clean with an ultrasonic cleaner, though this should be done with caution, especially if the stone has been treated or enhanced.
- Steam Cleaning: Steam cleaners are also generally safe for aquamarine, but again, caution is advised if the stone has been treated or if there are any inclusions that could be sensitive to heat.
Storage
- Avoid Hard Surfaces: Store aquamarine jewelry in a soft pouch or a jewelry box lined with a soft material to prevent scratches from other gemstones or metals.
- Separate Storage: If possible, store aquamarine separately from other gemstones, especially those with lower hardness or with cleavage planes, to avoid damage.
Handling
- Avoid Harsh Chemicals: Aquamarine should not be exposed to harsh chemicals, including household cleaners, perfumes, and lotions. These can dull the stone’s luster and potentially cause damage.
- Avoid Extreme Temperatures: While aquamarine is generally stable, it is best to avoid exposing it to extreme temperatures or sudden temperature changes, which can cause thermal shock and lead to fractures.
Professional Maintenance
- Regular Inspection: It is a good idea to have aquamarine jewelry inspected by a professional jeweler every few years to check for any signs of wear, damage, or loose settings.
- Repolishing: Over time, the surface of aquamarine can become scratched or dulled. A professional jeweler can repolish the stone to restore its brilliance.
