The third month of the year holds a unique distinction in the world of birthstones, offering not one, but two distinct gems for those born in March. This duality provides a fascinating study in contrast: one stone captures the ethereal, tranquil essence of the sky and sea, while the other embodies the deep, vital force of the earth. Aquamarine and bloodstone are the designated birthstones for March, each possessing a rich history, unique gemological properties, and a legacy of symbolism that has captivated humanity for centuries. This article delves into the comprehensive world of these two remarkable stones, exploring their geological origins, their journey through history and lore, their scientific characteristics, and the practical considerations for those who wear them.
While modern lists, such as the one provided by the American Gem Society and adopted by the jewelry industry, formally recognize both, the story of March’s birthstones is one of evolving tradition. Understanding both gems allows for a deeper appreciation of the month’s character, offering a choice between serene clarity and robust strength. For the gemstone enthusiast, jewelry buyer, or student of gemology, examining aquamarine and bloodstone side-by-side reveals the incredible diversity found within our planet’s mineral kingdom.
History and Lore: From Ancient Talismans to Modern Birthstones
The tradition of associating specific gemstones with birth months is a practice with ancient roots, believed to have originated with the Breastplate of Aaron, a religious garment described in the Book of Exodus. This breastplate was set with twelve stones, each representing one of the twelve tribes of Israel. Over time, these stones became linked to the twelve signs of the zodiac and, eventually, to the twelve months of the year. The specific assignment of stones to months has fluctuated over the centuries, but the core belief in the stones' unique powers and significance has remained a constant thread through history.
Aquamarine: The Sailor's Stone
Aquamarine’s history is deeply intertwined with the sea. Its name is derived from the Latin words aqua (water) and marina (sea), a direct and fitting description of its characteristic blue-to-blue-green hue. Ancient mariners believed that this gem was a treasure of mermaids and that it would protect them from peril on the ocean waves. They carried aquamarine amulets engraved with the image of Neptune, the Roman god of the sea, as talismans for safe passage and to ensure a safe return from long voyages. This lore established aquamarine as a stone of courage, safety, and good fortune, particularly for those who traveled over water.
Beyond its connection to sailors, aquamarine was also believed to be a stone of eternal youth. In ancient times, it was thought to be an effective antidote for the effects of poison and to cure ailments of the jaws, throat, and stomach. Its calming blue color was associated with tranquility and was believed to calm the mind and reduce stress. This association with peace and clarity has persisted into modern times, where aquamarine is often seen as a symbol of serenity and clear communication.
Bloodstone: The Martyr's Stone
Bloodstone, also known as heliotrope, carries a much darker and more intense history. This opaque, deep-green variety of chalcedony is characterized by striking red specks of iron oxide, which are responsible for its evocative name. In the Middle Ages, bloodstone was closely associated with the crucifixion of Christ. Legend holds that the stone was formed when the blood of Jesus dripped from the cross onto the dark green earth below, staining the stones forever. This powerful narrative transformed bloodstone into a potent Christian symbol, and it was often carved with scenes of the crucifixion and used as a devotional tool.
The stone’s reputation as a bringer of strength and protection grew from this association. It was believed to have the power to stop bleeding, to heal wounds, and to preserve health and life. Warriors in ancient times carried bloodstone into battle, believing it would staunch wounds and grant them victory. Its symbolism extended beyond physical protection; it was also thought to grant the wearer invisibility in times of danger and to control the rising of the sun and tides, linking it to powerful natural forces. This legacy makes bloodstone a gem of profound resilience, courage, and vitality.
Geological Formation and Sources
The origins of these two stones are as different as their appearances, one born of immense heat and pressure deep within the earth's crust, the other formed through volcanic activity and silica-rich fluids.
The Beryl Family: Aquamarine's Origins
Aquamarine is a member of the beryl family, making it a cousin to other well-known gems like emerald (green beryl), morganite (pink beryl), and goshenite (colorless beryl). Its beautiful blue color is the result of trace amounts of iron within its chemical structure. The most prized aquamarines exhibit a deep, saturated blue with a slight greenish tint, reminiscent of a tropical ocean.
This gemstone forms in large, hexagonal crystals that can grow to impressive sizes, sometimes weighing hundreds of pounds. These crystals are typically found in pegmatites—coarse-grained igneous rocks formed from the slow cooling of magma rich in water and other volatile compounds. As the magma cools, mineral-rich fluids circulate through fractures, depositing large crystals of minerals like beryl.
Historically, aquamarine was primarily sourced from Brazil, which remains a leading producer of high-quality material. However, significant deposits have also been found in other locations, including Pakistan, Madagascar, and several African nations. The discovery of large, flawless crystals in Brazil in the 20th century made aquamarine more accessible to the jewelry market, solidifying its place as a popular and beloved gemstone.
The Chalcedony Family: Bloodstone's Formation
Bloodstone is a variety of chalcedony, which is itself a microcrystalline form of quartz (silicon dioxide, SiO₂). Its distinctive appearance—a dark green base with red inclusions of iron oxide (specifically, jasper)—is the result of a unique geological process. The stone forms in areas where silica-rich fluids, often from volcanic activity, flowed into cavities of existing rock. These fluids, carrying dissolved iron, settled and solidified into layers of chalcedony and jasper, creating the characteristic red spots within the green matrix.
Unlike the large, faceted crystals of aquamarine, bloodstone is typically found in massive, opaque forms, which are then cut and polished into cabochons, beads, or carved intaglios. Its sources are more widespread. While India is a traditional and significant source for high-quality bloodstone, it is also found in Brazil, Australia, China, and parts of Europe. The relative abundance of chalcedony has historically made bloodstone a more affordable and widely available gem, contributing to its use not only in fine jewelry but also in cameos, seals, and other decorative objects.
Gemological Properties: A Scientific Comparison
For gemologists and discerning buyers, the physical and chemical properties of a gemstone are paramount. Aquamarine and bloodstone differ fundamentally in almost every gemological characteristic, from their crystal structure and transparency to their hardness and value.
Aquamarine: A Crystalline Classic
As a member of the beryl family, aquamarine has a chemical formula of Be₃Al₂(SiO₃)₆. Its defining characteristic is its transparency and vitreous (glass-like) luster. It is prized for its clarity, with high-quality stones being "eye-clean," meaning they lack visible inclusions.
- Hardness: On the Mohs scale of hardness, aquamarine ranks an 8. This makes it a durable gemstone suitable for all types of jewelry, including rings, which are subject to daily wear.
- Clarity and Treatments: Aquamarine is typically free of visible inclusions. The vast majority of aquamarine on the market has been heat-treated to remove greenish tones and produce a more desirable pure blue color. This treatment is stable, permanent, and widely accepted in the gem trade.
- Value: The value of aquamarine is determined by the depth and saturation of its color, its clarity, and its size. Deep, saturated blue stones command the highest prices.
Bloodstone: An Opaque Wonder
Bloodstone, as a variety of chalcedony, has a chemical formula of SiO₂ (the same as quartz). Its appearance is entirely different; it is opaque, with a waxy to vitreous luster when polished.
- Hardness: On the Mohs scale, bloodstone also ranks between 6.5 and 7, making it reasonably durable, though slightly less hard than aquamarine. It is suitable for jewelry, especially for pieces like pendants and earrings that are less prone to impact.
- Clarity and Treatments: The term "clarity" is not typically applied to opaque stones like bloodstone. Its value is based on the richness of its green color and the sharpness, distribution, and contrast of its red specks. Bloodstone is not typically treated.
- Value: Bloodstone is generally much more affordable than aquamarine. Its value is influenced by the artistic quality of any carving or the uniformity of the material for beads and cabochons.
The following table provides a direct comparison of the key gemological properties of these two March birthstones:
| Property | Aquamarine | Bloodstone (Heliotrope) |

Its proponents believe that wearing aquamarine can soothe fears, calm anxieties, and enhance clear, articulate communication. It is associated with the throat chakra, making it a popular stone for public speakers, performers, and anyone who wishes to speak their truth with confidence and clarity.
Beyond courage, aquamarine is also considered a stone of eternal youth and happiness. It is believed to reawaken love in married couples and to provide protection for travelers, a direct link to its ancient maritime lore. In modern crystal healing, aquamarine is used to treat ailments of the throat, jaw, and teeth and is thought to have a cooling and anti-inflammatory effect on the body.
Bloodstone: The Stone of Strength and Vitality
Bloodstone’s symbolism is rooted in its appearance and its history as a healer’s stone. It is known as the "stone of strength" and "stone of courage," believed to imbue the wearer with fortitude, endurance, and resilience. Its connection to blood and life force makes it a powerful talisman for vitality, physical health, and regeneration.
Bloodstone was historically used to stop bleeding and was believed to purify the blood and detoxify the liver and kidneys. In metaphysical circles, it is used to ground and stabilize energy, making it a stone for those who feel scattered or disconnected. It is also believed to enhance intuition and provide guidance in decision-making. For those born in March who are facing challenges, bloodstone is said to be a powerful ally, providing the inner strength needed to overcome obstacles.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone. Due to their different properties, aquamarine and bloodstone require slightly different approaches to cleaning and handling.
Caring for Aquamarine
With a hardness of 8, aquamarine is a relatively tough and resilient gemstone. It is durable enough for everyday wear in rings, bracelets, and other jewelry.
- Cleaning: Aquamarine can be safely cleaned using warm water, a mild soap (like dish soap), and a soft brush. Be sure to rinse it thoroughly to remove any soap residue. Avoid using harsh chemicals or household cleaners, as they could damage the stone or any metal settings it may be in. Ultrasonic cleaners are generally safe for aquamarine, but steam cleaning is not recommended, as the stone should not be subjected to rapid temperature changes.
- Storage: Store aquamarine separately from other jewelry to prevent it from being scratched by harder stones like diamonds or softer stones that it could scratch.
Caring for Bloodstone
Bloodstone, at 6.5 to 7 on the Mohs scale, is slightly softer than aquamarine and requires more gentle care. Its opaque nature also means that scratches can be more noticeable as they affect the surface luster.
- Cleaning: The safest method for cleaning bloodstone is with a soft, damp cloth. For a more thorough cleaning, use lukewarm water with a small amount of mild soap and a very soft brush. Gently scrub the surface and rinse well. As with aquamarine, avoid harsh chemicals. Ultrasonic cleaners should be used with caution, if at all, as the vibrations could potentially damage the stone, especially if it has any fractures. Steam cleaning is not recommended.
- Storage: Store bloodstone pieces in a soft cloth or padded jewelry box, away from harder stones that could scratch their polished surface.
