March, the third month of the year, is marked by the dual presence of two distinct yet equally significant birthstones: aquamarine and bloodstone. These gemstones, though different in appearance, share a rich history, deep symbolism, and a long-standing association with human culture. Aquamarine, with its serene blue hues and translucent beauty, evokes the calm of the sea, while bloodstone, with its vivid green base and red inclusions, symbolizes vitality and strength. Together, they represent the multifaceted character of March, a month of transition, renewal, and new beginnings.
This article delves into the historical and geological origins of these two birthstones, their gemological properties, the cultural and metaphysical beliefs surrounding them, and their significance in jewelry and modern gemology. By exploring the duality of March’s birthstones, we uncover a deeper understanding of their enduring appeal and the roles they have played across time.
The Historical Origins of March Birthstones
The tradition of birthstones is deeply rooted in ancient history, with references dating back to the 1st century AD. One of the earliest connections between gemstones and the calendar months is found in the Biblical account of the 12 stones of Aaron’s Breastplate, as described in the Book of Exodus. These stones were believed to represent the 12 tribes of Israel and were carried by the high priest during religious ceremonies. Over time, these stones were matched with the 12 zodiac signs and the 12 months of the year, forming the basis of the modern birthstone tradition.
In early historical records, bloodstone was the only gemstone associated with March. Bloodstone, a type of chalcedony, was known for its vivid green color and red specks of iron oxide, which were interpreted as drops of blood. It was considered a symbol of courage and healing and was often used in protective amulets. However, due to the limitations of gem identification in ancient times, the exact identities of the stones mentioned in historical texts remain a topic of debate among gemologists.
The practice of wearing birthstones corresponding to one's birth month became more widespread in the 15th and 16th centuries, particularly in Germany and Poland, where jewelers began crafting and selling birthstone jewelry. The standardized list of birthstones, as recognized today, began to take shape in the 19th century. A significant milestone in this process was the publication of birthstone poems by Tiffany & Co. in 1870, which helped to popularize the concept of birthstones as personal adornments and gifts.
Interestingly, the name "March" itself is derived from the Roman god Mars, the deity of war. The month was originally the first in the Roman calendar before the addition of January and February. March was a time when Roman soldiers resumed their campaigns after the winter pause, and it was also a period of agricultural and seasonal renewal. These associations with strength, renewal, and the changing of the seasons are reflected in the symbolic meanings of the two March birthstones.
Geological Formation and Sources of March Birthstones
Aquamarine and bloodstone differ significantly in their geological formation and the locations where they are found. Understanding these differences provides insight into the rarity, availability, and physical properties of each gemstone.
Aquamarine
Aquamarine is a variety of the mineral beryl, a beryllium aluminum silicate. The blue color of aquamarine is caused by the presence of iron (Fe) in its crystal structure. The most highly prized aquamarine stones are those with a clear blue or blue-green color, as these are the most visually striking and representative of the gem’s namesake. Aquamarine is generally transparent to translucent, allowing light to pass through and enhancing its brilliance.
Aquamarine is found in pegmatite deposits, which are coarse-grained igneous rocks formed from the slow cooling of magma. These conditions allow for the formation of large, well-developed crystals, which is one reason why aquamarine can grow to considerable sizes—sometimes weighing several kilograms. The finest aquamarine is sourced from Brazil, particularly from the states of Minas Gerais and Bahia. Other notable sources include Nigeria, Zambia, and Madagascar.
Aquamarine is known for its durability, with a Mohs hardness of 7.5 to 8, making it suitable for a wide range of jewelry applications, including rings, necklaces, and bracelets. Its high luster and cleavage-resistant structure also contribute to its popularity in fine jewelry.
Bloodstone
Bloodstone, in contrast, is a type of chalcedony, a microcrystalline quartz. Its name comes from its green base with red inclusions, which resemble drops of blood. These red spots are iron oxide, and the green color is due to the presence of chromite or other iron-bearing minerals. Bloodstone is typically opaque, and it is often cut into cabochons rather than faceted stones, as its surface is best appreciated in its natural, smooth form.
Bloodstone is found in sedimentary rocks, particularly in quartz-rich deposits. The most notable sources of bloodstone are India, Brazil, and the United States. Indian bloodstone, in particular, is highly regarded for its deep green color and well-defined red spots, making it the most valuable and sought-after variety.
Bloodstone has a Mohs hardness of 6.5 to 7, which is slightly lower than aquamarine, making it more prone to scratches and damage. As a result, bloodstone is often used in pendants, earrings, and other jewelry pieces that are less likely to experience frequent wear and impact. Despite its lower hardness, bloodstone is still a durable gemstone when handled with care.
Gemological Properties of March Birthstones
The gemological properties of aquamarine and bloodstone highlight the differences in their physical characteristics, making them suitable for different types of jewelry and purposes.
Aquamarine
Aquamarine has the following key gemological properties:
- Chemical Formula: Be₃Al₂(SiO₃)₆
- Hardness (Mohs Scale): 7.5 to 8
- Color: Blue to blue-green, caused by iron
- Clarity: Generally transparent to translucent
- Cut: Typically faceted, often in oval or emerald cuts
- Luster: Vitreous (glassy)
- Specific Gravity: 2.66 to 2.83
- Refractive Index: 1.56 to 1.60
- Cleavage: Perfect in one direction, making it sensitive to impact
Aquamarine is prized for its clarity and color, with the most valuable stones being those that are free of inclusions and have a consistent, even color. Because of its high hardness and excellent luster, aquamarine is ideal for everyday wear, particularly in rings and pendants.
Bloodstone
Bloodstone, while a different type of gemstone, also has distinct gemological properties:
- Chemical Formula: SiO₂ (Silica)
- Hardness (Mohs Scale): 6.5 to 7
- Color: Green with red inclusions (iron oxide)
- Clarity: Opaque
- Cut: Typically cabochon
- Luster: Waxy to vitreous
- Specific Gravity: 2.60 to 2.61
- Refractive Index: 1.53 to 1.54
- Cleavage: No cleavage; fracture is conchoidal
Bloodstone is best appreciated in cabochon cuts, which showcase the contrast between its green body and the red "blood" spots. The opacity of bloodstone means that it is not as luminous as aquamarine, but its bold color and unique pattern make it a distinctive and meaningful gemstone. Bloodstone is often used in pendants and earrings, where its visual impact can be fully appreciated.
Symbolism and Metaphysical Beliefs
Both aquamarine and bloodstone carry a wealth of symbolism and metaphysical beliefs, many of which have been passed down through generations and cultures.
Aquamarine
Aquamarine has long been associated with the sea and the calming influence of water. Ancient mariners believed that aquamarine could calm the waves and protect sailors from the dangers of the sea. In some cultures, it was also believed to bring good fortune and safe passage on voyages. The gemstone's name, derived from the Latin words aqua (water) and mare (sea), reinforces its connection to water and the ocean.
In modern metaphysical beliefs, aquamarine is considered a stone of serenity, courage, and communication. It is believed to help reduce anxiety and promote a sense of peace and clarity. Aquamarine is also thought to enhance self-expression and encourage honest communication, making it a popular stone for those in need of confidence and clarity in their personal and professional lives.
Bloodstone
Bloodstone is one of the oldest known gemstones used for its healing and protective properties. In ancient times, it was believed that bloodstone could heal wounds and stop bleeding, which is why it was often carried by warriors and healers. The red inclusions in bloodstone were interpreted as drops of blood, and the stone was thought to imbue the wearer with vitality, strength, and courage.
In modern metaphysical practices, bloodstone is considered a stone of vitality and grounding. It is believed to help with decision-making, increase confidence, and promote a sense of justice and truth. Bloodstone is also associated with physical healing, particularly in the digestive and circulatory systems. It is thought to stimulate the immune system and support the body’s natural healing processes.
Both aquamarine and bloodstone are believed to enhance spiritual awareness and intuition, making them popular choices for meditation, healing, and spiritual growth. Their contrasting properties—aquamarine’s calming influence and bloodstone’s energizing effect—make them a complementary pair, representing the balance of serenity and strength.
Care and Cleaning of March Birthstones
Proper care and cleaning are essential to maintaining the beauty and longevity of aquamarine and bloodstone. While both gemstones are relatively durable, they do require specific handling and cleaning methods to prevent damage and maintain their appearance.
Aquamarine
Aquamarine is a hard and durable gemstone, but it can still be damaged by harsh chemicals and sudden temperature changes. To clean aquamarine jewelry, use a mild soap solution and a soft cloth or brush. Avoid using ammonia, bleach, or other strong chemicals, as these can damage the gemstone or its setting. After cleaning, rinse the stone thoroughly with lukewarm water and dry it with a soft cloth.
Aquamarine should be stored separately from other gemstones to prevent scratches, especially from harder stones like diamonds or sapphires. It is also advisable to avoid exposing aquamarine to direct sunlight for extended periods, as this can cause fading or discoloration over time.
Bloodstone
Bloodstone is slightly more sensitive than aquamarine, with a lower hardness and no cleavage, but it is still a relatively durable gemstone. To clean bloodstone, use a soft cloth and a mild soap solution, and avoid using ultrasonic or steam cleaners, as these can damage the stone or loosen its setting.
Because bloodstone is opaque and often set in cabochons, it is best to clean it with a soft cloth rather than a brush, as a brush may scratch the surface or remove the polish. After cleaning, rinse the stone with lukewarm water and dry it with a soft cloth.
Bloodstone should be stored in a cool, dry place, away from direct sunlight and heat sources, which can alter the color of the stone or cause it to lose its luster. It is also recommended to store bloodstone separately from other gemstones, particularly harder stones like diamonds, to prevent scratches and abrasions.
