Aquamarine, with its captivating blue hues reminiscent of the sea, holds a prominent place as the birthstone for March and a cherished gemstone for commemorating the 19th wedding anniversary. This article delves into the history, geological origins, gemological properties, and symbolism of aquamarine, drawing exclusively from available sources to provide a comprehensive overview of this beloved gem.
History and Lore
Aquamarine’s history is interwoven with maritime traditions and beliefs in its protective powers. While specific dates regarding its initial discovery are not detailed in the provided sources, its presence in historical collections indicates a long-standing appreciation. A notable example is the significant aquamarine presented to First Lady Eleanor Roosevelt by the Brazilian government in 1936, a dark blue rectangular step-cut stone weighing 1,298 carats. This gift underscores the gem’s historical importance and its association with prominent figures.
Further demonstrating its historical significance, the Smithsonian Institution houses the Dom Pedro Aquamarine, believed to be the largest faceted aquamarine in the world, weighing 10,363 carats. Fashioned into a striking obelisk by Berndt Munsteiner, this piece exemplifies the artistry and scale achievable with this gemstone.
More recently, aquamarine has gained royal recognition through its association with Princess Diana and Meghan Markle, with the latter incorporating a piece from Diana’s private collection into her engagement ring. This connection has further elevated the gem’s profile and desirability. Beyond specific historical events, aquamarine is traditionally given as a gift for the 19th wedding anniversary, symbolizing enduring love and happiness.
Geological Formation and Sources
Aquamarine forms in pegmatite deposits, specifically in primary (hard rock) and secondary (weathered) formations. The Brazilian state of Minas Gerais has been a crucial source of aquamarine for over two centuries. The region’s diverse landscape, encompassing rocky hills, rivers, savannahs, and forests, hosts these gem-bearing deposits, particularly near the gem center of Teófilo Otoni. The sources do not detail other significant mining locations.
Gemological Properties
Aquamarine is prized for its clarity and brilliance, boasting a Mohs hardness of 7.5-8. This relatively high hardness makes it a durable choice for jewelry, particularly for rings intended for everyday wear. The gem’s color ranges from light blue to aqua blue, with higher saturation generally increasing its value. Clarity is also a key factor, with high-quality aquamarine exhibiting minimal inclusions and maximizing transparency.
Aquamarine can be cut into various shapes, including oval, pear, emerald, marquise, and heart-shaped, allowing for diverse design possibilities. Jewelers also employ cutting techniques like the “fantasy cut,” as seen in the Dom Pedro Aquamarine, to maximize the gem’s brilliance and unique characteristics.
The following table summarizes key gemological properties:
| Property | Description |
|---|---|
| Hardness (Mohs) | 7.5-8 |
| Color | Light blue to aqua blue |
| Clarity | High transparency, minimal inclusions preferred |
| Common Cuts | Oval, pear, emerald, marquise, heart-shaped |
Symbolism and Metaphysical Beliefs
Throughout history, aquamarine has been attributed with various symbolic meanings and metaphysical properties. It is believed to be connected to the “vishuddha chakra,” or “Throat Chakra,” and is thought to alleviate throat infections. Some believe it can help restore hormonal balance, promoting calmness and mental focus.
Further purported benefits include relief from thyroid and pituitary gland-related issues, reducing gland inflammation and aiding in the healing of sinusitis. Aquamarine is also associated with improving respiratory health and alleviating lung problems. For those struggling with public speaking anxiety, the gem is believed to enhance confidence and wisdom.
Care and Cleaning
Due to its hardness, aquamarine is relatively durable and can withstand regular wear. However, as with any gemstone, proper care is essential to maintain its brilliance. The sources do not provide specific cleaning instructions, but given its hardness, gentle cleaning with warm, soapy water and a soft brush is likely suitable.
Aquamarine in Jewelry
Aquamarine is a versatile gemstone used in a wide range of jewelry designs. Rings featuring aquamarine are particularly popular, including solitaire designs, vintage-inspired settings with intricate metalwork, and modern combinations with diamonds. Halo settings, where aquamarine is encircled by diamonds, enhance the gem’s sparkle and allure.
Beyond rings, aquamarine is also featured in earrings, pendants, and necklaces. Designs range from simple solitaire pendants to elaborate “Color by the Yard” pieces incorporating aquamarine alongside other gemstones. The availability of various metal options, including sterling silver, yellow gold, white gold, rose gold, and platinum, allows for customization to suit individual preferences.
Ring Considerations
When selecting an aquamarine ring, several factors should be considered. Color and clarity are paramount, with higher saturation and fewer inclusions increasing the gem’s value. The cut should enhance the gemstone’s brilliance, and the setting should securely hold the stone while complementing its beauty.
It is important to ensure accurate ring sizing, as adjustments may be limited once the ring is made, particularly for eternity or stone-set designs. Professional sizing is recommended before purchase.
Conclusion
Aquamarine stands as a captivating gemstone, celebrated for its serene blue color, durability, and rich history. From its ancient associations with maritime lore to its modern-day status as a beloved birthstone and anniversary gem, aquamarine continues to enchant and inspire. Its geological origins in the Brazilian state of Minas Gerais, combined with its unique gemological properties, make it a truly remarkable and enduring treasure.
