Introduction
March is one of only two months in the traditional birthstone calendar to be represented by two official gemstones. Aquamarine, with its serene blue hues reminiscent of the sea, and bloodstone, known for its deep green base with distinctive red flecks, each offer a distinct aesthetic and symbolic identity. Both have a long history of use in jewelry and spiritual traditions, and each has its own unique set of physical and metaphysical properties. Whether chosen for personal connection, spiritual significance, or simply for their beauty, aquamarine and bloodstone are cherished by many.
This article will explore the history and lore of these gemstones, their geological formation and sources, their gemological properties such as hardness and chemical composition, their symbolic meanings across cultures, and practical advice on how to care for these precious stones. By the end, readers will have a comprehensive understanding of the dual birthstones of March and their enduring appeal.
History and Lore
The tradition of birthstones dates back to biblical times, with roots in the 1st century AD. The earliest references to birthstones come from the High Priest Aaron’s breastplate, as described in the Book of Exodus. This breastplate was adorned with 12 gemstones, each representing one of the twelve tribes of Israel. Over time, these stones were linked to the 12 months of the year and the zodiac signs. By the 1500s, jewelers in Germany and Poland began selling birthstone jewelry, making these stones accessible to the general public. The standardized lists of birthstones that are familiar today began to take shape in the 19th century, with the publication of birthstone poems by Tiffany & Co. in 1870.
For March, bloodstone was originally the sole birthstone. However, the addition of aquamarine to the list reflects the evolution of gemological knowledge and the growing appreciation for its beauty and properties. Both stones have been revered across different cultures and historical periods, often associated with protection, healing, and spiritual clarity.
Bloodstone, also known as heliotrope, is a type of chalcedony that displays a deep green color with red spots, often interpreted as symbolic of the blood of Christ. It was highly valued in medieval Europe for its perceived healing properties and protective powers. Bloodstone was commonly used in amulets and talismans, and it was believed to stop bleeding and promote physical and emotional strength. Its historical use in religious and medicinal contexts contributed to its enduring symbolism as a stone of courage and vitality.
Aquamarine, on the other hand, has long been associated with the sea. Derived from the Latin phrase aqua marina, meaning "water of the sea," this gemstone was believed to protect sailors and ensure safe passage across the oceans. Ancient mariners carried aquamarine stones to ward off tempests and calm turbulent waters. It was also considered a symbol of youth, hope, and fidelity, making it a popular choice for wedding rings and anniversary gifts.
Both aquamarine and bloodstone have made their way into modern birthstone traditions, where they continue to be celebrated for their beauty, symbolism, and historical significance.
Geological Formation and Sources
Aquamarine
Aquamarine is a variety of beryl, a mineral composed of beryllium, aluminum, silicon, and oxygen. It forms in igneous rocks, particularly in granitic pegmatites and metamorphic rocks, where it crystallizes in six-sided structures. The blue color of aquamarine is due to trace amounts of iron within the crystal lattice. The intensity of the blue hue varies depending on the concentration of iron and the presence of other trace elements.
Naturally occurring deep blue aquamarines are the most highly prized due to their rarity and vibrant color. However, lighter or yellowish beryl can sometimes be heated to produce a blue aquamarine, a process that is well-documented in gemological literature. This treatment is stable and does not alter the gemstone’s physical properties.
The primary sources of aquamarine are in Brazil, where large deposits yield high-quality stones. Other notable sources include Colombia, the Ural Mountains in Russia, Madagascar, and India. In the United States, aquamarine can be found in Colorado, Maine, and North Carolina, though the stones from these locations are generally smaller and less intensely colored than those from Brazil.
Bloodstone
Bloodstone is a chalcedony, a type of microcrystalline quartz, that is distinguished by its deep green color and the presence of red spots or flecks. The green color comes from chromite or iron oxide, while the red flecks are caused by iron oxide inclusions or tiny hematite crystals. This combination gives bloodstone its distinctive appearance and has contributed to its historical association with blood and vitality.
Bloodstone is most commonly found in India, where it has been mined for centuries. Other significant sources include Brazil, Australia, and the United States, particularly in California and Arizona. Despite the availability of bloodstone in various regions, the finest specimens—those with a deep green base and well-distributed red flecks—remain highly sought after in the jewelry trade.
Gemological Properties
Aquamarine
Aquamarine is known for its clarity and brilliance, making it a popular choice for faceted jewelry. It has a Mohs hardness of 7.5 to 8, which means it is relatively durable and suitable for daily wear. However, due to its potential for cleavage (a tendency to split along certain planes), it should be handled with care, especially in settings that may cause impact or stress to the stone.
The chemical composition of aquamarine is Be₃Al₂(SiO₃)₆, and it has a refractive index ranging from 1.56 to 1.60. Its specific gravity is between 2.67 and 2.83, which is relatively high for a beryl. Aquamarine is typically transparent to translucent and can be found in a range of colors from light blue to deep sea blue, with occasional greenish undertones.
Aquamarine is often cut into faceted gems, which enhance its brilliance and color. The emerald cut, oval cut, and round brilliant cut are among the most popular choices for aquamarine jewelry.
Bloodstone
Bloodstone, as a form of chalcedony, is a silica-based mineral with a chemical composition of SiO₂. It has a Mohs hardness of 6.5 to 7, making it slightly less durable than aquamarine. Due to its opaque nature and the presence of inclusions, bloodstone is typically cut into cabochons rather than faceted gems. This helps to showcase the stone’s unique pattern of green and red and enhances its luster.
The specific gravity of bloodstone is approximately 2.60, and it has a refractive index of around 1.54 to 1.55. Bloodstone is generally translucent to opaque and is known for its chatoyancy (a cat’s eye effect) in some specimens, though this is not common. The deep green color and red flecks give bloodstone a striking and distinctive appearance, making it a popular choice for pendants, rings, and beads.
Symbolism and Metaphysical Beliefs
Both aquamarine and bloodstone have long been associated with symbolic and metaphysical properties, many of which have persisted across different cultures and historical periods.
Aquamarine
Aquamarine is often regarded as a stone of calm and serenity. Its connection to the sea has led to beliefs in its ability to promote emotional stability, soothe anxiety, and enhance communication. In ancient times, it was believed that aquamarine could calm the waters and protect sailors from storms. This protective power has extended into modern interpretations, where aquamarine is considered a stone of courage, helping individuals face fears and overcome obstacles.
Aquamarine is also associated with youth and vitality, making it a popular choice for those seeking to maintain a sense of energy and optimism. It is believed to support the throat chakra, enhancing the ability to express oneself clearly and truthfully. In some traditions, aquamarine is thought to promote fidelity and love, making it an ideal gemstone for romantic partnerships.
Bloodstone
Bloodstone has a strong association with physical strength and vitality. Its name and appearance have led to its use as a protective stone, particularly in times of illness or injury. In medieval Europe, bloodstone was believed to stop bleeding and accelerate the healing of wounds. It was also used to strengthen the circulatory system and promote overall health.
In addition to its physical benefits, bloodstone is considered a stone of courage and determination. It is believed to help individuals stay grounded and focused, especially in times of stress or conflict. Bloodstone is also associated with truth and integrity, making it a valuable tool for those seeking to maintain honesty and clarity in their lives.
Both aquamarine and bloodstone are often used in metaphysical healing practices, either as standalone gemstones or in combination with other stones. Their contrasting energies—calm and grounding—make them complementary in certain spiritual practices.
Care and Cleaning
Proper care is essential to maintaining the beauty and longevity of both aquamarine and bloodstone. Due to their differing physical properties, each stone requires slightly different handling and cleaning methods.
Aquamarine
Aquamarine, with its relatively high hardness (7.5 to 8) and good toughness, can be cleaned with warm, soapy water using a soft brush. It should be rinsed thoroughly and dried with a soft cloth. Ultrasonic and steam cleaners are generally safe for aquamarine, though caution should be exercised if the stone has been filled or treated with any inclusions or fractures.
Aquamarine should be stored separately from harder gemstones to prevent scratches. It is also advisable to avoid exposure to extreme temperatures or sudden temperature changes, as this can cause thermal shock and damage the stone.
Bloodstone
Bloodstone is slightly softer (6.5 to 7) and more opaque than aquamarine, which means it requires a bit more care. While it can also be cleaned with warm, soapy water and a soft brush, it is best to avoid ultrasonic and steam cleaners, as these can potentially damage the stone’s inclusions or cause micro-fractures.
Bloodstone should be stored in a soft pouch or individually wrapped to prevent scratches from other gemstones. It is also important to avoid exposure to harsh chemicals or acids, as these can dull the stone’s luster.
Both aquamarine and bloodstone benefit from periodic inspections by a professional jeweler, especially if they are set in rings or other jewelry that may experience frequent wear. Any signs of loosening settings, surface damage, or discoloration should be addressed promptly to ensure the longevity of the gemstone.
