Bloodstone, a gemstone of striking contrast and deep symbolism, stands as one of the two traditional birthstones for the month of March. Characterized by its dark green base color splashed with vivid red spots resembling droplets of blood, this opaque chalcedony variety has captivated humanity for millennia. Its journey from an ancient talisman to a modern birthstone is a narrative woven from geological processes, historical significance, and enduring metaphysical beliefs. This article explores the multifaceted nature of bloodstone, delving into its geological origins, its physical properties, its rich tapestry of symbolism, and its practical care, all based on the information provided by authoritative gemological and historical sources.
History and Lore
The history of bloodstone is as vivid as its appearance, stretching back at least two thousand years. Its use as a popular gemstone is well-documented, with its reputation for protection and power established long before its designation as a modern birthstone in 1912. The stone's very name is rooted in ancient beliefs and observations. The alternate name, heliotrope, derives from the ancient Greek words meaning "to turn the sun." An ancient belief held that placing these March birthstones in water would turn the sun red, a testament to the stone's perceived connection to solar and elemental forces.
The primary name, bloodstone, stems from the stone's distinctive appearance and the symbolic interpretations that followed. In the Middle Ages, Christians popularly associated the gem's blood-red spots with the crucifixion of Christ, viewing it as a powerful symbol of martyrdom and sacrifice. This religious significance added a layer of sacred meaning to the stone's existing lore.
Beyond Christian symbolism, bloodstone has been consistently linked to themes of vitality, courage, and protection across various cultures. Its association with blood naturally led to beliefs about its ability to staunch hemorrhages, a folkloric property noted by mineralogist and folklorist George F. Kunz. This sympathetic magic—where a stone resembling blood is believed to control it—was a common thread in ancient healing practices.
Furthermore, bloodstone's connection to the Roman god Mars, the god of war, cemented its status as a symbol of bravery and strength. This link is particularly fitting, as March is named after Mars. The stone was often worn as a talisman by soldiers and warriors, believed to offer protection in battle and to bolster courage. This ancient association persists in modern times, where bloodstone is prized by athletes and individuals seeking to enhance their physical strength and endurance. Even today, in some cultural practices, fine bloodstones may be crushed into a powder and used as an aphrodisiac, highlighting its enduring reputation for vitality and power.
Geological Formation and Sources
Bloodstone is a variety of chalcedony, which is a cryptocrystalline form of quartz (silicon dioxide, SiO2). Its formation is a geological process that involves the infiltration of silica-rich fluids into fractures or cavities of host rocks. Over time, these fluids solidify, creating the dense, microcrystalline structure characteristic of chalcedony. The green base color of bloodstone is attributed to tiny inclusions of minerals such as chlorite, amphibole, and pyroxene. The striking red spots, which give the stone its name, are concentrations of iron oxide minerals, most likely hematite. This combination of green and red minerals creates the stone's signature appearance.
The most highly regarded bloodstones exhibit a solid, deep forest green base color with a light, sharp spatter of clearly visible blood-red dots. While the ideal is a dark green with bright red, some specimens may show yellow inclusions; these are sometimes specifically referred to as plasma, though the term is also used more broadly for bloodstone in general.
Regarding global sources, bloodstone can be found in several countries. Major deposits exist in India, Brazil, Australia, Germany, and the United States. India is particularly notable, as it is the source of most bloodstone found in the modern marketplace, and its finest specimens are traditionally considered the highest quality. Bloodstone can be discovered filling fractures or cavities in other rocks or as pebbles in riverbeds, a common occurrence for many chalcedony varieties.
Gemological Properties
Understanding the physical and gemological properties of bloodstone is essential for its identification, valuation, and care. As a member of the chalcedony family, it shares many characteristics with other quartz varieties but has distinct features.
Hardness and Durability: On the Mohs hardness scale, bloodstone has a hardness of approximately 6.5 to 7. This makes it a relatively durable gemstone, suitable for various types of jewelry. It possesses no cleavage and has a tough tenacity, meaning it is resistant to breaking and chipping. These properties contribute to its suitability for everyday wear, though, like all gemstones, it can be scratched by materials harder than itself.
Color and Appearance: The classic bloodstone is an opaque, dark green variety of chalcedony adorned with splashes of bright red. The opacity is due to the included mineral matter, which constitutes at least several percent of its weight. The stone's luster is typically waxy to vitreous when polished.
Chemical Composition and Structure: Bloodstone is composed of silicon dioxide (SiO2) and has a trigonal crystal structure. It is cryptocrystalline, meaning its crystals are too small to be seen with the naked eye, which contributes to its opacity and smooth texture when cut.
Cut and Form: Bloodstone is typically cut and polished as a cabochon to best display its opaque color and distinctive spots. Faceted cuts are less common but can be found in striking examples. Due to its relative hardness and lack of cleavage, it is a versatile gem for lapidary work.

Symbolism and Metaphysical Beliefs
The symbolism of bloodstone is deeply intertwined with its visual characteristics and historical narrative. Its primary association is with courage and strength, stemming from its connection to blood and the Roman god Mars. This has made it a perennial favorite for those embarking on challenging endeavors or seeking to bolster their inner resolve.
Protection is another cornerstone of its metaphysical lore. From ancient talismans worn by soldiers to modern amulets, bloodstone has been believed to create a shield against physical and spiritual harm. Its reputation for warding off the "evil eye" and negative energies is a common thread in various cultural traditions.
The stone's link to vitality and health is perhaps its most enduring belief. The "blood" in bloodstone is not merely a visual trait; it is symbolically tied to life force and circulation. Historically, it was thought to be effective in staunching bleeding and treating blood-related ailments. This symbolism extends to preserving health and youth, making it a stone of renewal and longevity.
In modern metaphysical circles, bloodstone is considered a powerful lucky charm, particularly for athletes and those in competitive fields. It is believed to enhance physical performance, increase stamina, and provide the mental fortitude needed to overcome obstacles. Its association with the month of March and the zodiac signs of Pisces and Aries further personalizes its symbolic power for those born under these signs.
Care and Cleaning
Proper care is necessary to maintain the beauty and integrity of a bloodstone gemstone. Fortunately, its durable nature makes it relatively easy to care for.
Cleaning: Bloodstone can be safely cleaned at home using warm, soapy water and a soft brush. Gently scrub the stone to remove any dirt or oils, paying special attention to any crevices where debris might accumulate. After cleaning, rinse the stone thoroughly with clean water and dry it completely with a soft, lint-free cloth.
Precautions: To protect the stone, it is important to keep it away from harsh chemicals, such as household cleaners, bleach, or strong acids, as these can damage its surface. While bloodstone is heat-resistant, it is advisable to avoid exposing it to extremely high temperatures, such as those found in a kiln or during jewelry repair involving direct heat.
Storage: To prevent scratches, store your bloodstone jewelry separately from other pieces. The best practice is to keep it in a soft fabric pouch or a lined jewelry box. Although bloodstone has a hardness of 6.5 to 7, it can be scratched by harder materials like corundum (ruby, sapphire) or diamond. Keeping it in a dedicated compartment will ensure its polished surface remains smooth and its red spots vibrant.
