March 10 falls within the month of March, which is associated with two primary birthstones: aquamarine and bloodstone. These two gems have long been cherished for their beauty, historical significance, and symbolic meanings. While aquamarine is often the more popular choice for those born in March, bloodstone remains a powerful and revered alternative. This article explores the origins, geological properties, historical uses, symbolism, and care of these two March birthstones, drawing on the most reliable and well-documented sources from the field of gemology and history.
Introduction
For those born on March 10, the choice of a birthstone can be both a personal and symbolic decision. March is unique in the birthstone calendar because it has two official birthstones: aquamarine and bloodstone. These stones differ greatly in appearance—aquamarine is a clear or lightly hued blue gem that resembles the sea, while bloodstone is a dark green gem with red flecks resembling blood. Despite their differences, both have been historically valued for their protective and symbolic properties.
This article will delve into the geological and chemical properties of both aquamarine and bloodstone, their historical and cultural significance, and their modern applications in jewelry and holistic practices. We will also explore how to care for these gems to ensure their beauty and integrity endure over time.
History and Lore
The tradition of associating gemstones with the months of the year dates back to ancient times. One of the earliest references to birthstones appears in the Old Testament, in the Book of Exodus, where the high priest Aaron is described as wearing a breastplate adorned with twelve gemstones, each corresponding to a tribe of Israel. Over time, these stones were linked to the months of the year and the zodiac signs, forming the basis for the modern birthstone calendar.
By the early centuries AD, the concept of birthstones had evolved further, with various cultures developing their own lists based on religious, spiritual, and scientific beliefs. Bloodstone, for instance, was one of the earliest recorded March birthstones. It was believed to have the power to stop bleeding and heal wounds, a belief that may have contributed to its name. In medieval Europe, bloodstone was often used in healing rituals and was considered a powerful protective stone.
Aquamarine, on the other hand, gained prominence in the Renaissance and Baroque periods. Its name, derived from the Latin aqua marinus (meaning "water of the sea"), reflects its deep connection to maritime culture. Ancient sailors believed aquamarine could calm the seas and protect them from shipwrecks. It was also thought to promote happiness in marriage and ensure safe travels, making it a popular choice for both sailors and travelers.
Both stones have been used in various cultural contexts. For example, in the 18th and 19th centuries, aquamarine was often used in engagement rings, symbolizing love and fidelity. Bloodstone was also valued as a protective stone, particularly for warriors and travelers.
In the modern era, the birthstone tradition has been standardized, with aquamarine and bloodstone officially recognized as the two birthstones for March. These gems continue to be popular in jewelry and are often chosen for their beauty, symbolism, and historical significance.
Geological Formation and Sources
Aquamarine
Aquamarine is a variety of the mineral beryl, which has the chemical formula Be₃Al₂(SiO₃)₆. It is composed of beryllium, aluminum, and silicate ions, with its characteristic blue coloration coming from trace amounts of iron. The presence of iron in different oxidation states (Fe²⁺ and Fe³⁺) is responsible for the range of blue tones seen in aquamarine, from pale blue to deep blue-green.
Aquamarine forms in igneous and metamorphic rocks, particularly in pegmatites and granitic environments. It is typically found in large, well-formed crystals, which makes it ideal for faceting. The gem is most commonly mined in Brazil, where it occurs in alluvial deposits in the states of Minas Gerais and Bahia. Other notable sources include Nigeria, Madagascar, Pakistan, and the United States.
Aquamarine is generally transparent to slightly translucent and is known for its clarity. It has a hardness of 7.5 to 8 on the Mohs scale, making it relatively durable and suitable for use in jewelry. However, it is sensitive to heat and can lose its color if exposed to high temperatures.
Bloodstone
Bloodstone is a type of chalcedony, which is a microcrystalline variety of quartz. Its chemical formula is SiO₂ (silicon dioxide), and its red spots are caused by inclusions of iron oxide (typically hematite or goethite). The red flecks are what give bloodstone its name and distinctive appearance.
Bloodstone is formed in sedimentary environments, particularly in areas where chalcedony-rich rock is exposed to iron-rich groundwater. The iron oxidizes and creates the characteristic red spots that contrast with the green base of the stone. It is usually cut into cabochons rather than being faceted, as its opacity and inclusions make it unsuitable for faceting.
Bloodstone is found in various parts of the world, with significant deposits in India, the United States (particularly in the state of Indiana), and Europe (notably in Poland and Germany). It is a relatively durable gemstone with a hardness of 6.5 to 7 on the Mohs scale. However, due to its inclusions and the presence of iron, it can be sensitive to harsh chemicals and prolonged exposure to direct sunlight.

Symbolism and Metaphysical Beliefs
Aquamarine
Aquamarine has long been associated with peace, calm, and emotional balance. In ancient times, it was believed to help sailors navigate the seas and protect them from shipwrecks. It was also considered a gemstone that promoted happiness in marriage and ensured the safety of travelers.
In the Renaissance period, aquamarine was believed to stimulate the intellect and enhance intuition, making it a popular stone among scholars and students. It was also used in engagement rings to symbolize love and fidelity.

Bloodstone
Bloodstone has a rich history of symbolic and protective properties. In medieval Europe, it was believed to have the power to stop bleeding and promote healing, hence its name. It was often used in healing rituals and was considered a powerful protective stone for warriors and travelers.
In the ancient world, bloodstone was associated with Mars, the Roman god of war, and was believed to bring strength and courage to the wearer. It was also thought to purify the body and promote physical vitality.
In modern metaphysical practices, bloodstone is associated with the root chakra and is believed to ground the wearer, promote courage, and enhance vitality. It is also considered a stone of protection and is often used in amulets and talismans.
Care and Cleaning
Both aquamarine and bloodstone require careful handling to maintain their beauty and integrity.
Aquamarine
Aquamarine is relatively durable but can be sensitive to heat and certain chemicals. It should be cleaned with warm, soapy water and a soft brush. Ultrasonic cleaners can be used with caution, but steam cleaning is not recommended. It should be stored separately from harder gemstones to prevent scratches.
Aquamarine should be kept away from direct sunlight and high temperatures, as it can fade over time. When not in use, it is best to store it in a soft cloth or jewelry box to protect it from dust and abrasion.
Bloodstone
Bloodstone is more sensitive than aquamarine and should be handled with care. It can be cleaned with a mild soap and a soft cloth. Harsh chemicals and ultrasonic cleaners should be avoided, as they can damage the stone. Steam cleaning is not recommended for bloodstone.
Bloodstone should be stored in a cool, dark place to prevent fading and oxidation. It should be kept away from direct sunlight and heat sources, as prolonged exposure can cause the red flecks to darken or fade. It is best to store it separately from harder gemstones to prevent scratching.
