History and Lore
Bloodstone has a long and storied history that dates back to ancient times. It was widely regarded as a protective and empowering stone, often worn by warriors, athletes, and leaders for courage and strength. The gemstone's name is derived from its appearance: the deep green chalcedony base is often speckled with red inclusions, which were believed to resemble drops of blood. This visual motif inspired many of the legends and beliefs associated with bloodstone.
In ancient civilizations, bloodstone was considered a powerful talisman. The Greeks and Romans used it in amulets and seals, believing it could enhance physical stamina and ward off danger. The gemstone was also associated with the zodiac signs Aries and Pisces, both of which have roots in the month of March, further cementing its connection to this time of year.
One of the most notable references to bloodstone comes from the "Gregorian birthstone poem," a piece of verse that dates back to the 19th century and was popularized by the jewelry company Tiffany & Co. in 1870. The poem reads:
"Who in this world of ours their eyes
In March first open shall be wise,
In days of peril firm and brave,
And wear a bloodstone to their grave."
This poetic tribute reflects the deep reverence for bloodstone and its perceived role in granting wisdom, courage, and protection to those born in March.
Historically, bloodstone was also the March birthstone in the ancient Roman, Polish, Arabic, Hebrew, and old Hindu calendars. Before becoming associated with the month of March, bloodstone was the zodiac stone for Aries and Pisces, both of which are partially aligned with March. This connection to the zodiac further underscores the gemstone's symbolic importance and its longstanding cultural significance.
In the ancient world, bloodstone was often used by warriors and athletes, who believed it could enhance their physical strength and endurance. Its association with bravery and vitality made it a popular choice for those engaged in combat or physical endeavors. The gemstone was also believed to have purifying properties, making it a favored tool in holistic and healing practices.
By the 1950s, bloodstone was officially recognized as one of the modern birthstones for March, alongside aquamarine. However, bloodstone's traditional status as the primary March birthstone in many ancient calendars and cultures has not been diminished. Its rich history and enduring symbolism continue to make it a cherished gemstone for those born in March and for collectors and enthusiasts of historical jewelry and gemstones.
Geological Formation and Sources
Bloodstone is a variety of chalcedony, a microcrystalline form of quartz. Its deep green color is primarily due to the presence of iron, while the red inclusions are typically composed of red jasper or iron oxide. The red specks are what give bloodstone its distinctive appearance and are often interpreted as symbolic of blood, which is central to many of the gemstone's legends and beliefs.
The formation of bloodstone occurs in sedimentary rocks, where chalcedony is deposited in layers. Over time, these layers can become infused with iron and other minerals, resulting in the characteristic green and red hues. The process of geological transformation that creates bloodstone is slow and complex, making high-quality specimens relatively rare.
Bloodstone is found in several parts of the world, including India, Australia, and Brazil—three of the primary sources for this gemstone. India is particularly well-known for producing some of the finest bloodstone, with the red inclusions often being especially vivid and well-distributed. Australian and Brazilian deposits also yield high-quality bloodstone, though the color and clarity can vary depending on the specific location and geological conditions.
Once extracted, bloodstone is typically cut into cabochons or beads, as its opaque nature and unique patterns make it ideal for these styles. Faceting is less common for bloodstone due to its lack of transparency, but in some cases, it may be used to highlight specific features or to create a more polished appearance.
The rarity of high-quality bloodstone, especially those with a high concentration of red inclusions, contributes to its value and desirability among collectors and jewelers. While bloodstone is not as expensive as precious gemstones like diamonds or rubies, its historical significance and symbolic associations make it a prized gemstone in its own right.
Gemological Properties
Bloodstone is a type of chalcedony, which is a microcrystalline form of quartz. Its gemological properties are defined by its composition, color, and physical characteristics. Below is a detailed overview of its key gemological features:
| Property | Detail |
|---|---|
| Chemical Formula | SiO₂ (silicon dioxide) |
| Color | Deep green with red inclusions (often iron oxide or red jasper) |
| Hardness (Mohs Scale) | 6.5–7 |
| Luster | Waxy to vitreous |
| Transparency | Opaque |
| Crystal System | Trigonal (as chalcedony) |
| Cleavage | No cleavage; conchoidal fracture |
| Density (specific gravity) | 2.58–2.64 g/cm³ |
| Refractive Index | 1.53–1.54 |
| Common Cuts | Cabochon, beads, and sometimes faceted |
| Common Uses | Jewelry (rings, pendants, bracelets), amulets, and seals |
Bloodstone is not as hard as some other gemstones like diamonds or sapphires, but its hardness of 6.5–7 on the Mohs scale makes it suitable for many types of jewelry. Its lack of cleavage is an advantage, as it makes the gemstone less prone to chipping or breaking. The conchoidal fracture, however, means that it can be somewhat fragile if struck at the wrong angle.
Due to its opaque nature, bloodstone is typically cut into cabochons or beads, which help to showcase its unique color and pattern. The waxy to vitreous luster of bloodstone gives it a smooth and polished appearance, making it an attractive choice for jewelry and decorative objects.
One of the most distinctive features of bloodstone is its color. The deep green base is caused by the presence of iron, while the red inclusions are usually iron oxide or red jasper. These red specks are what give bloodstone its name and are often interpreted as symbolic of blood, which is central to many of the gemstone's legends and beliefs.
Bloodstone is also relatively dense, with a specific gravity of 2.58–2.64 g/cm³. Its refractive index ranges from 1.53 to 1.54, which is relatively low compared to other gemstones. This low refractive index means that bloodstone does not exhibit the same level of brilliance as more refractive gemstones like diamonds or zircons.
Despite these characteristics, bloodstone remains a popular gemstone for its unique appearance and historical significance. Its combination of green and red hues, along with its symbolic associations, makes it a distinctive and meaningful choice for those born in March.
Symbolism and Metaphysical Beliefs
Bloodstone has been associated with a wide range of symbolic and metaphysical properties throughout history. Its deep green base and red inclusions have inspired many beliefs about its healing, protective, and empowering qualities. In many cultures, bloodstone has been regarded as a powerful amulet that can enhance strength, courage, and vitality.

However, the gemstone's historical significance and enduring popularity suggest that it has played an important role in many cultures and traditions.
Care and Cleaning
Bloodstone, like all gemstones, requires proper care to maintain its beauty and longevity. Due to its relatively low hardness (6.5–7 on the Mohs scale), bloodstone is not as durable as some other gemstones, and it can be sensitive to certain types of damage. However, with the right care and handling, bloodstone jewelry can remain beautiful and intact for many years.
One of the most important aspects of caring for bloodstone is avoiding exposure to extreme heat or direct sunlight for prolonged periods. Bloodstone can lose its color or become discolored if exposed to strong light or heat, especially if it contains red inclusions. It is best to store bloodstone jewelry in a cool, dark place when not in use, and to avoid leaving it in direct sunlight or near heat sources.
Bloodstone should also be protected from harsh chemicals, which can damage the surface or alter its color. It is advisable to remove bloodstone jewelry before using household cleaners, perfumes, or other chemical products. If bloodstone jewelry becomes dirty, it should be cleaned gently using a soft cloth and mild soap and water. It is important to avoid using abrasive cleaners or ultrasonic cleaners, as these can damage the gemstone's surface or cause it to become discolored.
When storing bloodstone jewelry, it is best to keep it in a soft cloth or jewelry box to prevent it from coming into contact with harder gemstones or metal surfaces. This helps to prevent scratches or other types of damage that can occur from friction or impact.
Bloodstone is also sensitive to physical impacts and should be handled with care to avoid chipping or breaking. While it does not have cleavage, it can still be damaged if struck at the wrong angle or subjected to excessive force. It is advisable to avoid wearing bloodstone jewelry during activities that involve heavy physical contact or the risk of impact.
Bloodstone jewelry can be polished and cleaned professionally if necessary, but it is important to choose a jeweler who is experienced in handling this type of gemstone. Professional cleaning should be done with care to avoid using any harsh chemicals or abrasive materials that could damage the gemstone.
By following these care and cleaning guidelines, bloodstone jewelry can be preserved for many years, allowing its beauty and symbolism to be enjoyed by future generations.
