March is a unique month in the world of birthstones, as it is associated with two distinct gemstones: aquamarine and bloodstone. These stones, though vastly different in appearance and symbolism, share a common purpose in the realm of birthstones—offering both aesthetic beauty and a rich historical and spiritual significance. Whether you are drawn to the serene blue hues of aquamarine or the bold red-dotted green of bloodstone, the March birthstones embody a duality of meaning and function that has captivated gem lovers for centuries.
This article delves into the geological properties, cultural lore, and practical considerations of these two gemstones, drawing exclusively from authoritative sources and historical records. We will explore how each stone formed, where it is found, and what it represents across different cultures and eras. Additionally, we will touch upon the gemological characteristics that make these stones both beautiful and valuable, and how to care for them to preserve their brilliance.
History and Lore
Aquamarine: The Stone of the Sea and Sky
Aquamarine, the pale blue to deep blue-green gemstone, has long been associated with the ocean. In ancient times, it was believed that the stone came from the treasure chests of mermaids, a belief that led sailors to carry aquamarine as a lucky charm to protect against shipwrecks and other maritime dangers. The Roman scholar Pliny the Elder noted in his writings that aquamarine was used in ancient Rome as a symbol of youth and happiness, and its name—derived from the Latin words aqua (water) and marina (seawater)—reinforces its connection to the sea.
In more recent history, aquamarine has been cherished as a symbol of calm and clarity. Ancient Greeks engraved aquamarine into intaglios—small carved gems used as seals—believing that the stone could provide protection and promote mental clarity. The Chinese and Japanese also valued aquamarine, using it to create seals, dolls, and netsuke (small toggles used in traditional Japanese clothing).
In the modern era, aquamarine has taken on additional symbolic meanings. It is often associated with serenity, hope, and courage, making it a popular choice for those seeking emotional balance. As the birthstone for March, it represents a transition period in the year—bridging the cold of winter with the renewal of spring.
Bloodstone: The Stone of Vitality and Protection
Bloodstone, also known as heliotrope, is a form of chalcedony that is typically a deep green with flecks of red. Its red spots are caused by inclusions of iron oxide, which give it a striking appearance. Bloodstone is often associated with vitality, courage, and protection, and its name reflects a legend tied to the crucifixion of Christ. According to the legend, when Roman soldiers pierced Christ’s side with a spear, drops of his blood fell onto green jasper at the foot of the cross, forming the first bloodstone.
This gemstone has a long and storied history in religious and spiritual traditions. It was widely used in the Middle Ages for carving religious scenes, particularly in Italy. A famous example is the sculpture The Descent from the Cross by Matteo del Nassaro, which features bloodstone used to represent the blood of Christ. Bloodstone was also believed to have healing properties and was used in traditional medicine to treat wounds and fevers.
In addition to its physical healing properties, bloodstone was thought to offer spiritual protection. It was believed to strengthen the will, enhance courage, and promote inner strength. These qualities made it a popular choice for warriors and leaders, and it was often carried as a talisman in battle or during times of great stress.
Geological Formation and Sources
Aquamarine: A Beryl with a Blue Heart
Aquamarine is a variety of the mineral beryl, which is composed of beryllium, aluminum, silicon, and oxygen. It forms in the hexagonal crystal system and is typically found in pegmatite rock veins, where it grows as free six-sided crystals. The color of aquamarine is due to trace amounts of iron in the crystal structure. Naturally occurring deep blue aquamarines are the most prized, as they are both rare and visually striking.
The best commercial sources of aquamarine are found in Brazil, particularly in the state of Minas Gerais. Brazil has been a major supplier of aquamarine for over two centuries, and the gemstone is so closely associated with the country that it is often referred to as the "Brazilian blue." Other notable sources include Colombia, the Ural Mountains of Russia, Madagascar, and India. In the United States, aquamarine can be found in Colorado, Maine, and North Carolina. Colorado is particularly significant, as aquamarine was designated as the state gem in 1971.
Aquamarine is typically found in both primary (hard rock) and secondary (weathered) deposits. In primary deposits, the gemstone is found in its original host rock, while in secondary deposits, it is found as loose pebbles in riverbeds or alluvial deposits. This dual formation makes aquamarine relatively accessible compared to other gemstones, though the finest quality stones remain rare and valuable.
Bloodstone: A Chalcedony with a Fiery Heart
Bloodstone is a form of chalcedony, which is a microcrystalline variety of quartz. It forms in sedimentary rock and is composed of tiny interlocking quartz crystals that give it a smooth, waxy appearance. The green color of bloodstone is due to the presence of chlorite or other green minerals, while the red flecks are caused by iron oxide.
Bloodstone is typically found embedded in rocks or as pebbles in riverbeds. The best sources of bloodstone are India, Brazil, and Australia. Indian bloodstone is particularly well-known for its deep green color and distinct red spots, making it a favorite among gemstone collectors and carvers. Brazilian and Australian sources also produce high-quality bloodstone, though it is generally less intense in color than its Indian counterpart.
Bloodstone is often mined in alluvial deposits, where it is found loose in riverbeds or along the banks of streams. This makes it relatively easy to extract, though finding high-quality specimens can be challenging. Once extracted, bloodstone is typically cut and polished to enhance its natural beauty and bring out the contrast between the green base and the red flecks.
Gemological Properties
Aquamarine: A Durable and Radiant Gem
Aquamarine is known for its durability and brilliance, making it an excellent choice for jewelry. On the Mohs scale of hardness, it ranks at 7.5 to 8, which means it is relatively resistant to scratches and abrasions. This hardness, combined with its toughness, makes aquamarine a suitable gemstone for everyday wear, though it can be vulnerable to sudden impacts or heat.
The refractive index of aquamarine ranges from 1.56 to 1.58, which gives it a bright and lively appearance. It is also a doubly refractive gemstone, meaning that light is bent in two different directions as it passes through the crystal. This property can sometimes cause doubling or a slight "flicker" effect in the stone, especially in larger sizes.
Aquamarine is typically transparent to translucent, and it is often cut into a range of shapes, including emerald cuts, round brilliant cuts, and pear-shaped cuts. The most valuable aquamarines are those with a deep blue color, as these are the rarest and most sought after. Lighter blue or blue-green stones are more common and tend to be less expensive.
One interesting property of aquamarine is its color stability. Unlike some other gemstones that can fade or change color over time, aquamarine is generally stable under normal conditions. However, exposure to high heat can cause color changes, and some stones may be heat-treated to enhance their color. This treatment is not permanent and can fade over time if the stone is exposed to prolonged heat.
Bloodstone: A Stone of Strength and Contrast
Bloodstone is a relatively hard gemstone, with a Mohs hardness of 6.5 to 7. This makes it suitable for use in jewelry, though it is not as durable as aquamarine. Like aquamarine, bloodstone is also a doubly refractive gemstone, but its refractive index is slightly lower, ranging from 1.53 to 1.54. This gives it a slightly different optical character than aquamarine, with a more subdued brilliance.
Bloodstone is typically opaque to translucent, and it is often cut into cabochons or beads. Its most distinguishing feature is the contrast between the green base and the red flecks, which are caused by iron oxide inclusions. These inclusions can vary in size and distribution, giving each bloodstone a unique appearance. The finest bloodstones have a deep green color and well-distributed red spots that resemble drops of blood.
Bloodstone is also known for its toughness. While it is not as hard as aquamarine, it is relatively resistant to breaking or chipping. However, it is more susceptible to scratches, especially from harder gemstones or materials. This means that bloodstone jewelry should be handled with care, and it is best stored separately from other gemstones to prevent scratches.
One unique property of bloodstone is its historical use in carvings and engravings. Due to its fine-grained texture and relative softness, it is well-suited for detailed work. This has made it a popular choice for religious carvings, amulets, and other decorative items throughout history.

Care and Cleaning
Aquamarine: Gentle Handling for Long-Lasting Beauty
Aquamarine is a relatively durable gemstone, but it still requires proper care to maintain its beauty and integrity. Because it has a hardness of 7.5 to 8, it is resistant to scratches and abrasions, but it can be damaged by sudden impacts or exposure to high heat.
To clean aquamarine, use a soft cloth and warm, soapy water. Avoid using ultrasonic cleaners or steam cleaners, as these can cause damage to the stone. It is also important to avoid exposing aquamarine to harsh chemicals or solvents, as these can cause the stone to lose its luster or change color.
When storing aquamarine jewelry, keep it in a separate compartment or pouch to prevent it from coming into contact with other gemstones. This will help prevent scratches and damage. Avoid exposing aquamarine to prolonged heat or direct sunlight, as this can cause the color to fade over time.
Bloodstone: Care for Strength and Clarity
