Whether you are a gemstone enthusiast, a jewelry buyer, or simply curious about the significance of March’s birthstone, this comprehensive guide provides a detailed and authoritative look at aquamarine.
History and Lore
Aquamarine’s history is as deep and enduring as the sea it resembles. The name "aquamarine" is derived from the Latin words aqua (water) and marina (of the sea), a fitting tribute to its color and the beliefs surrounding it. Ancient mariners held aquamarine in high regard, believing it to be a protective talisman that ensured safe passage across the oceans. Sailors would carry aquamarine to calm the seas and ward off the dangers of storms and shipwrecks.
In addition to its maritime associations, aquamarine was also thought to bring happiness in marriage. It was believed to bestow the wearer with courage, clarity, and a harmonious spirit. In medieval times, beryl—of which aquamarine is a type—was considered a gemstone of intellectual fortitude and amiable nature. It was said to quicken the mind and make the wearer unconquerable in battle or litigation.
Aquamarine also holds significance in the annals of famous gifts and collections. In 1936, the government of Brazil presented First Lady Eleanor Roosevelt with a remarkable aquamarine weighing 1,298 carats. This gem was part of a larger aquamarine rough that weighed nearly 1.3 kilograms and is now housed at the Franklin D. Roosevelt Presidential Library and Museum. Another notable specimen is the Dom Pedro Aquamarine, a massive 10,363-carat gem displayed at the Smithsonian Institution. This extraordinary piece is believed to be the largest faceted aquamarine in the world and was crafted by renowned German lapidary Berndt Munsteiner using the fantasy cut technique.
Geological Formation and Sources
Aquamarine is a member of the beryl family, a mineral group that also includes emerald and morganite. Chemically, aquamarine is composed of beryllium aluminum silicate with trace amounts of iron responsible for its blue coloration. The presence of iron in varying concentrations results in the range of colors seen in aquamarine, from pale blue to deep greenish-blue hues.
Geologically, aquamarine forms in granitic pegmatites—coarse-grained igneous rocks that form from the slow cooling of magma. These environments allow for the growth of large, well-formed crystals. The Brazilian state of Minas Gerais has been a significant source of aquamarine for over two centuries. The region's diverse landscapes, including rocky hills, rivers, and forests, provide the ideal conditions for aquamarine formation. Specifically, aquamarine deposits are found in the eastern portion of the state near the gem center of Teófilo Otoni, in both primary (hard rock) and secondary (weathered) pegmatite deposits.
Other notable sources of aquamarine include Nigeria, Madagascar, Pakistan, and the United States. Each of these regions contributes to the global supply of aquamarine, ensuring that this gemstone remains accessible to jewelers and collectors alike.
Gemological Properties
Aquamarine is prized not only for its beauty but also for its favorable gemological properties, which make it a durable and desirable gemstone. On the Mohs scale of hardness, aquamarine ranks at 7.5 to 8, making it relatively hard and suitable for use in a wide range of jewelry, including rings, earrings, and pendants. This hardness ensures that aquamarine can withstand daily wear and tear, though it is still advisable to take precautions to protect it from impacts and abrasions.
The refractive index of aquamarine ranges from 1.56 to 1.58, which contributes to its brilliance and luster. When cut properly, aquamarine can display a lively sparkle that enhances its already captivating color. The gemstone is typically free from inclusions, appearing as clear as water, which is a testament to its purity and quality.
Aquamarine is available in a variety of cuts, including round, oval, emerald, and fantasy cuts. The choice of cut can influence the appearance of the gemstone, with some cuts emphasizing the blue tones more effectively than others. Additionally, aquamarine’s color can vary depending on the lighting, appearing slightly different under natural sunlight versus artificial light.
One of the most appealing aspects of aquamarine is its versatility in jewelry design. Its pale to deep greenish-blue color complements a wide range of settings, from classic yellow gold to modern platinum and rose gold. This adaptability has made aquamarine a popular choice for both traditional and contemporary jewelry pieces.
Symbolism and Metaphysical Beliefs
Beyond its physical properties, aquamarine is rich in symbolism and metaphysical significance. It has long been associated with calmness, clarity, and communication. In ancient times, it was believed to help sailors navigate the seas with confidence and to protect them from the perils of the ocean. This protective quality extended beyond the maritime realm, with aquamarine also being considered a stone of emotional stability and inner peace.
In modern times, aquamarine is often referred to as the "stone of clear communication." It is believed to help individuals express themselves with honesty and clarity, making it an ideal companion for those who seek to improve their communication skills. Whether in personal relationships or professional settings, aquamarine is thought to foster understanding and harmony.
Aquamarine is also associated with love and friendship. It was historically believed to attract friends and lovers and to reconcile differences between enemies. This attribute has made aquamarine a popular choice for wedding jewelry and romantic gifts. Its calming influence is thought to promote emotional balance, reducing anxiety and encouraging a sense of tranquility.
In addition to its emotional benefits, aquamarine is also linked to physical well-being. Some sources suggest that it can help to alleviate infections and promote a healthy immune system. While these claims are not widely accepted in formal gemology, they reflect the enduring belief in the gemstone’s healing properties.
Aquamarine is also connected to the concept of renewal. As the birthstone for March, it is seen as a symbol of spring and the rebirth of nature. Its oceanic hues evoke the idea of flowing with life’s currents and embracing change with grace and resilience.
Care and Cleaning
To preserve the beauty and longevity of aquamarine jewelry, it is important to follow proper care and cleaning guidelines. While aquamarine is relatively durable, it can still be damaged by harsh chemicals, extreme temperatures, and physical impacts.
One of the most important steps in caring for aquamarine jewelry is to remove it before engaging in activities that could expose it to potential damage. This includes showering, swimming, exercising, and using household cleaning products. These activities can cause the gemstone to become scratched or the metal setting to tarnish or corrode.
When it comes to cleaning, it is best to use a gentle, non-abrasive method. A soft, dry cloth can be used to wipe away surface dirt and fingerprints. For a deeper clean, a mild soap and water solution can be used, but it is important to avoid using harsh chemicals or ultrasonic cleaners, as these can damage the gemstone or its setting.
After cleaning, it is essential to dry the jewelry thoroughly with a soft cloth to prevent water spots or residue. Storing aquamarine jewelry in a cool, dry place is also recommended. Each piece should be stored separately to prevent scratches and tangling.
For gold vermeil or sterling silver pieces, additional care may be necessary. Gold vermeil, which is a layer of 18k gold over sterling silver, should be polished gently to maintain its luster. Over-polishing can wear down the gold layer, so it is advisable to use the provided polishing cloth and avoid excessive rubbing.
Sterling silver pieces can tarnish over time, especially when exposed to air and moisture. To prevent tarnishing, it is best to store these pieces in an airtight container with a tarnish-resistant lining. If tarnish does occur, a silver polishing cloth can be used to restore the shine.
By following these care and cleaning practices, aquamarine jewelry can maintain its brilliance and beauty for years to come. Proper maintenance not only enhances the appearance of the gemstone but also ensures that it remains a treasured heirloom.
