Aquamarine, the birthstone prominently associated with March 31st, is a gemstone celebrated for its serene beauty and rich historical significance. This pale blue to blue-green variety of the mineral beryl has been treasured for centuries, not only for its aesthetic qualities but also for the symbolic and metaphysical properties attributed to it. This article provides a comprehensive overview of aquamarine, exploring its geological origins, cultural importance, and practical care, drawing solely from available sources to offer insights for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
Aquamarine’s history is interwoven with tales of seafaring lore and ancient beliefs. The name itself, derived from the Latin words “aqua” (water) and “marina” (sea), directly reflects its captivating resemblance to the ocean’s tranquil hues. Throughout history, this gemstone has been revered for its perceived protective and calming powers. For those born on any day in March, ruby is also considered a guardian angel birthstone, believed to reconcile disagreements and strengthen bonds between friends and lovers, while also promoting health and improving mental state. Emerald, another March birthstone, was considered a sacred gem of the Atlanteans, symbolizing intelligence, wealth, and service to humanity.
Historically, aquamarine has been linked to various cultures and traditions. In some instances, it was chosen as an alternative to diamond in engagement rings, symbolizing fidelity and happiness. The Hindu Shastra associates a Gold Siva-Linga, shielded with Jaspers, as a March birthstone, demonstrating a deep reverence for the stone within Indian religious practices. Multiple other gemstones, including Jade, Jasper, and Amazonite, are also identified as March birthstones, reflecting a diverse range of beliefs and traditions.
Geological Formation and Sources
Aquamarine belongs to the beryl family, a group of minerals that also includes emerald and morganite. Its formation occurs in pegmatites, which are coarse-grained igneous rocks, and in alluvial deposits. The most significant sources of aquamarine are found in Brazil, particularly in the Minas Gerais region, characterized by its rocky hills and river landscapes. Pakistan’s Karakoram Foothills, situated at altitudes exceeding 3000 meters, also yield notable quantities of this gemstone.
Additional sources of aquamarine are located in Africa, specifically in Kenya, Madagascar, Nigeria, Zambia, and Mozambique. The African continent is considered to hold the most abundant resources of this valuable mineral. Bloodstone, another March birthstone, is primarily sourced from India, with smaller deposits found in Brazil, Australia, China, and the United States, typically occurring as pebbles.
Gemological Properties
Aquamarine is prized for its clarity and color, ranging from pale blue to a more intense blue-green. Its hardness falls between 7.5 and 8 on the Mohs scale, making it a durable gemstone suitable for various jewelry applications, including engagement rings, necklaces, and earrings.
The chemical composition of aquamarine is Be3Al2Si6O18, a beryllium aluminum silicate. The blue color is attributed to trace amounts of iron within the beryl crystal structure. Aquamarine typically exhibits good clarity, meaning it has few inclusions visible to the naked eye.
A notable example of a significant aquamarine is the Gachala Emerald, an 858-carat gem discovered near Bogota, Colombia, now part of the Smithsonian collection. While technically an emerald, its inclusion highlights the beryl family’s capacity for producing exceptional gemstones.
Symbolism and Metaphysical Beliefs
Throughout history, aquamarine has been imbued with symbolic meaning. It is often associated with calmness, courage, and clarity. In Sanskrit, ruby, another March birthstone, is known as ‘ratnaraj’ (king of precious gemstones) and ‘padmaraga’ (red as a lotus), symbolizing reconciliation and strengthening relationships.
Aquamarine is believed to enhance communication, reduce stress, and promote inner peace. In crystal healing practices, it is considered a stone that fosters emotional balance and encourages self-expression. Bloodstone, the traditional March birthstone, represents strength and vitality. The diverse range of March birthstones – including Ruby, Emerald, Jade, Jasper, and Amazonite – each carry unique symbolic weight, allowing individuals to choose a gem that resonates with their personal beliefs and energies.
Care and Cleaning
Due to its relatively high hardness, aquamarine is a durable gemstone that can withstand regular wear. However, like all gemstones, it requires proper care to maintain its brilliance. Aquamarine can be safely cleaned using warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can potentially damage the stone.
It is also advisable to store aquamarine jewelry separately from other gemstones to prevent scratching. Regular cleaning and careful storage will help preserve the beauty of aquamarine for generations to come.
March Birthstone Variations
The designation of birthstones for March is notably diverse. While aquamarine and bloodstone are the most commonly recognized, several other gemstones are associated with this month, depending on the specific system used. These include ruby (as a guardian angel birthstone), emerald (as a special apostle birthstone), jade, jasper, and amazonite.
The variety of birthstone options reflects the historical evolution of these associations, often rooted in biblical references or astrological alignments. The choice of which birthstone to embrace is ultimately a personal one, based on individual preference and connection to the gem’s unique properties and symbolism. For those born between March 1 and 20, Jade is also considered a birthstone.
