The months of March and April are graced by two distinct yet equally captivating gemstones: aquamarine and diamond. Aquamarine, with its serene hues reminiscent of the ocean, and diamond, renowned for its unparalleled hardness and brilliance, each hold a unique place in history, lore, and the world of jewelry. This article will explore the geological origins, historical significance, gemological properties, and symbolism of these two birthstones, drawing exclusively from available sources.
A History of Maritime Protection and Royal Favor
Aquamarine’s history is deeply intertwined with the sea. Its name, derived from the Latin “aqua marina,” directly translates to “seawater,” reflecting its characteristic blue to blue-green coloration. Ancient mariners believed that aquamarine possessed protective qualities, safeguarding sailors on their voyages. Sources indicate this belief stemmed from the stone’s resemblance to the ocean itself, imbuing it with the sea’s power and tranquility. This association with safe passage and good fortune has persisted through the ages.
Diamond, conversely, boasts a history rooted in strength and resilience. Its name originates from the Greek word “adamas,” meaning “unconquerable,” a testament to its exceptional hardness. While initially found in riverbeds, diamond mining as a formalized practice began in the late 1860s. Throughout history, diamonds have been symbols of power, wealth, and enduring love.
Both stones have enjoyed periods of high esteem. Until the 18th century, amethyst rivaled diamonds, emeralds, and rubies in value, while aquamarine, though not always reaching the same price point, was prized for its clarity and beauty. Diamonds, however, have consistently maintained their position as a highly valued gemstone, becoming synonymous with status and lasting commitment.
Geological Formation and Sources
Aquamarine belongs to the beryl family, a group of minerals that also includes emerald. It forms in pegmatites, which are coarse-grained igneous rocks. The presence of iron within the crystal structure is responsible for aquamarine’s blue hues, further influenced by natural radiation. Notably, sources highlight the Santa Maria mine in Brazil as a particularly famous source of high-quality aquamarine crystals, often found in relatively large and clean formations.
Diamonds, formed deep within the Earth’s mantle under immense pressure and heat, are brought to the surface through volcanic eruptions. Historically found in riverbeds, their mining evolved with the development of more sophisticated extraction techniques in the late 19th century. Specific source locations are not detailed in the provided materials.

Symbolism and Metaphysical Beliefs
Beyond their aesthetic appeal, both aquamarine and diamond carry rich symbolic weight. Aquamarine, linked to the sea, is believed to promote emotional balance and clarity. It is said to represent serenity, foresight, and joy, mirroring the calming influence of the ocean.
Diamond’s symbolism is deeply rooted in its exceptional durability. Representing “unconquerable” strength, it has long been associated with enduring love, commitment, and unwavering relationships. Diamonds are also seen as symbols of purity, clarity, and status. Amethyst, the February birthstone, is associated with royalty and is thought to protect against intoxication. It is believed to clear negative thoughts and provide inner peace.
Modern and Traditional Birthstone Lists
Birthstone traditions have evolved over time, resulting in both modern and traditional lists. According to one source, the modern birthstone for March is aquamarine, while the traditional birthstone is bloodstone. For April, both the modern and traditional birthstones are diamond. November has both Golden Topaz and Citrine as modern birthstones, while Topaz is the traditional stone. December has Blue Zircon, Blue Topaz, and Tanzanite as modern birthstones, and Turquoise and Lapis Lazuli as traditional stones.
Care and Cleaning
Due to its hardness of 7 on the Mohs scale, aquamarine is relatively durable and can withstand everyday wear. However, it is still susceptible to scratching from harder materials. Cleaning aquamarine jewelry can be done with warm, soapy water and a soft brush.
Diamonds, being the hardest gemstone, are exceptionally durable. However, they can still accumulate dirt and oils, diminishing their brilliance. Regular cleaning with warm, soapy water and a soft brush is recommended. Professional cleaning and inspection are advisable to maintain a diamond’s sparkle and ensure the setting is secure.

Aquamarine is a versatile gemstone suitable for a wide range of jewelry designs, from solitaire rings to elaborate pendants and earrings. Its pale blue hues complement various metal settings, including white gold, yellow gold, and platinum. Aquamarine rings, particularly those featuring halo settings with diamonds, are popular choices for March birthdays.
Diamonds, renowned for their brilliance and fire, are the cornerstone of many classic jewelry pieces, especially engagement rings. Their versatility allows for a multitude of cuts, settings, and designs, making them suitable for any style.
Conclusion
