March is a month of transition and renewal, and its birthstones reflect this duality with their contrasting yet complementary characteristics. While many months are associated with a single gemstone, March is uniquely represented by two: Aquamarine and Bloodstone. These stones, though vastly different in appearance and symbolism, share a common thread of protection, strength, and serenity. Together, they form a rich tapestry of gemological significance that has captivated cultures and collectors for centuries. This article explores the geological origins, historical uses, and symbolic meanings of these two March birthstones, offering a comprehensive look at their roles in both jewelry and cultural traditions.
Introduction
The gemstone tradition assigns specific stones to each month of the year, often rooted in ancient lore and historical significance. For March, this tradition recognizes both Aquamarine and Bloodstone as representative stones. Aquamarine, with its calming blue hues, is the most widely recognized modern birthstone for the month, while Bloodstone holds a place in traditional gemstone lore. These stones are not only prized for their beauty but also for their symbolic meanings—Aquamarine is associated with tranquility and courage, while Bloodstone is linked to vitality and strength.
This article will explore the geological formation and sources of these gemstones, their historical and cultural significance, their gemological properties, and their care and maintenance. We will also examine how these stones have been used in jewelry and what makes them appealing to collectors and wearers alike.
History and Lore
The history of Aquamarine is deeply entwined with the sea, a connection reflected in its name, which comes from the Latin aqua marina, meaning "water of the sea." As a member of the beryl family—related to emerald—Aquamarine has been revered for its clarity and vibrant color. In ancient times, sailors carried Aquamarine as a talisman to protect them from the perils of the ocean. This belief in its protective qualities was not limited to seafaring; it was also thought to bring good fortune in marriage and to protect the wearer from harm in battle and litigation.
Bloodstone, on the other hand, has a more varied and symbolic history. Known for its dark green base with red flecks of iron oxide, Bloodstone has long been associated with vitality and strength. In medieval Europe, it was believed that the red specks resembled drops of blood and thus symbolized the blood of Christ, making it a popular choice for religious amulets and signet rings. Bloodstone was also thought to improve blood health and was used in traditional medicine to treat ailments related to the circulatory system.
Despite their different historical uses, both stones have been valued for their protective and healing properties. Aquamarine's connection with the sea and its calming effect has made it a symbol of serenity and courage, while Bloodstone has been regarded as a stone of vitality and resilience. These symbolic associations have endured over time, contributing to the continued popularity of both stones as birthstones.
Geological Formation and Sources
Aquamarine is a variety of the mineral beryl, with its blue coloration coming from trace amounts of iron within the crystal structure. Beryl forms in granitic pegmatites and metamorphic rocks, where it crystallizes under high-temperature conditions. The presence of iron impurities during the formation process leads to the characteristic blue hues of Aquamarine. The most notable sources of high-quality Aquamarine include Brazil, particularly the states of Minas Gerais and Bahia, which are the largest suppliers of this gemstone. Other significant sources are found in Nigeria, Pakistan, and Madagascar. The widespread availability of Aquamarine has contributed to its accessibility and affordability, making it a popular choice in the jewelry market.
Bloodstone, also known as heliotrope, is a type of chalcedony, a microcrystalline variety of quartz. It is formed when iron oxide (hematite) is present within the chalcedony matrix, creating the red flecks that characterize the stone. Bloodstone is typically found in volcanic rocks, particularly in basaltic formations, and is commonly mined in India, Brazil, and the United States. India is the most significant source of Bloodstone, with the state of Rajasthan producing some of the finest examples of the stone. The presence of Bloodstone in these regions has contributed to its use in both traditional and contemporary jewelry.
Both Aquamarine and Bloodstone are relatively durable gemstones, with Aquamarine having a hardness of 7.5 to 8 on the Mohs scale and Bloodstone a hardness of 6.5 to 7. These hardness values make both stones suitable for use in jewelry, although Bloodstone is more susceptible to scratches and should be handled with care. The clarity and color of both stones can vary depending on the presence of inclusions and the concentration of iron, which can affect their overall appearance and value.
Gemological Properties
Understanding the gemological properties of a stone is essential for appreciating its beauty and durability. Below is a detailed comparison of the key properties of Aquamarine and Bloodstone, based on the information provided in the sources.

Many people today choose Aquamarine and Bloodstone for their symbolic meanings, using them as talismans for protection, strength, and emotional balance.
Care and Cleaning
Proper care is essential for maintaining the beauty and longevity of Aquamarine and Bloodstone. While both stones are relatively durable, they require different cleaning and storage methods to prevent damage.
Aquamarine
Aquamarine can be cleaned with mild soap and warm water. A soft brush can be used to gently remove any dirt or debris from the surface of the stone. It is important to avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone or its setting. After cleaning, the stone should be dried with a soft cloth to prevent water spots.
Aquamarine should be stored separately from other gemstones to avoid scratching. It is also advisable to keep it away from extreme temperatures and direct sunlight for prolonged periods, as this can affect its color and clarity. When not in use, Aquamarine jewelry should be stored in a soft cloth or jewelry box to protect it from dust and physical damage.
Bloodstone
Bloodstone is more delicate than Aquamarine and should be handled with care. It can be cleaned with a soft, damp cloth to remove any surface dirt. Harsh chemicals, ultrasonic cleaners, and abrasive materials should be avoided, as they can scratch or dull the stone's surface.
Because Bloodstone is typically cut as a cabochon, it is more prone to surface scratches than faceted stones. To protect it, it should be stored separately from harder gemstones. Bloodstone should also be kept away from extreme temperatures and direct sunlight, as prolonged exposure can affect its color and luster.
Both Aquamarine and Bloodstone benefit from regular inspection for signs of wear or damage. If any issues are noticed, such as loose settings or scratches, it is advisable to have the jewelry professionally inspected and repaired.
