March, often seen as a bridge between the cold of winter and the warmth of spring, is uniquely associated with two birthstones—aquamarine and bloodstone. These gemstones, while distinct in appearance, share a rich tapestry of history, symbolism, and gemological significance. Together, they reflect the dual nature of the month: one of transition and renewal. This duality makes March’s birthstones not only beautiful but deeply meaningful, especially for those born during this time of year.
This article explores the historical roots of birthstones, the geological and cultural significance of aquamarine and bloodstone, and their roles in jewelry and healing. It delves into the symbolic meanings and practical aspects of these two gems, offering a comprehensive view of their importance in both the gemological world and human culture.
History and Lore
The tradition of birthstones is ancient, with one of the earliest known references found in the Old Testament. According to the Book of Exodus, the High Priest’s Breastplate was adorned with 12 gemstones representing the 12 tribes of Israel. While the exact identification of these stones is debated, the tradition of associating gemstones with months and their symbolic meanings has persisted through the ages.
For March, the tradition of two birthstones is a relatively modern addition. While bloodstone has a longer history and was recognized as an alternative gemstone, aquamarine became the more prominent modern choice. The dual designation for March reflects the evolving nature of gemstone traditions, as well as the diverse qualities and meanings these stones embody.
Aquamarine, with its calming blue hues, has long been associated with the sea. Ancient sailors carried aquamarine as a talisman for protection against the dangers of the ocean. This gemstone was also thought to bring happiness in marriage and to quicken the intellect, making it a symbol of both emotional and intellectual strength.
Bloodstone, on the other hand, has a more earthy and grounded symbolism. Known for its deep green base and vivid red spots, bloodstone is believed to bring vitality and courage. Its name comes from the red spots of iron oxide, which resemble drops of blood, symbolizing life and strength.
Together, aquamarine and bloodstone represent both the tranquility and the strength associated with the month of March, making them fitting birthstones for those born during this time.
Geological Formation and Sources
Aquamarine
Aquamarine is a member of the beryl family, which also includes emerald. Its chemical composition is beryllium aluminum silicate, with the formula Be₃Al₂(SiO₃)₆. The gemstone’s color, ranging from pale blue to deep greenish-blue, is due to trace amounts of iron within the crystal structure. The finest aquamarines are those with a deep, intense blue color and excellent clarity.
Aquamarine is typically found in granite pegmatites and metamorphic rocks. The most notable sources of aquamarine are found in Brazil, particularly in the states of Minas Gerais and Bahia. Other significant sources include Nigeria, Madagascar, Pakistan, and Afghanistan. Brazil, however, remains the most prominent supplier of high-quality aquamarine.
Aquamarine is a relatively durable gemstone, with a hardness of 7.5–8 on the Mohs scale, making it suitable for a variety of jewelry pieces, including engagement rings, necklaces, and earrings. Its excellent clarity and vitreous luster contribute to its popularity in the jewelry market.
Bloodstone
Bloodstone, also known as heliotrope, is a type of jade that consists of chrysoprase (a green variety of chalcedony) with inclusions of hematite, which appear as red spots or flecks. The red spots are due to iron oxide, and the green base is caused by chromium or nickel.
Bloodstone is typically found in volcanic rock, where it forms in cavities and veins. The most significant source of bloodstone is India, particularly in the state of Madhya Pradesh. Other sources include Nepal, Brazil, and the United States. India has long been the primary supplier of bloodstone, with historical trade routes dating back centuries.
Bloodstone has a hardness of 6.5–7 on the Mohs scale, making it suitable for cabochons and pendants, though it is less commonly used in rings due to its relative softness. Its durability and unique appearance make it a popular choice for spiritual and healing jewelry.
Gemological Properties
Aquamarine
Aquamarine is prized not only for its beauty but also for its gemological properties. As a member of the beryl family, it is known for its excellent clarity and brilliance. The gemstone is typically colorless to pale green in its pure form, but the presence of iron gives it its characteristic blue to blue-green hues.
Aquamarine is transparent to translucent, and its refractive index ranges from 1.56 to 1.60. It has a specific gravity of 2.67–2.83, which is relatively light for a gemstone. The cleavage of aquamarine is basal (pinacoidal), meaning it can split along one direction, which can make it vulnerable to damage if not properly set in jewelry.
Aquamarine is often heated to enhance its color, a common and stable treatment in the gem trade. Heat treatment can deepen the blue color and remove any yellow or greenish tinge. This treatment is generally undetectable without specialized equipment and is widely accepted in the industry.
Bloodstone
Bloodstone is a microcrystalline quartz, and its gemological properties reflect its composition. It is translucent to opaque, with a vitreous to waxy luster. Its refractive index is approximately 1.55–1.57, and its specific gravity is 2.60–2.80, making it slightly heavier than aquamarine.
One of the most notable properties of bloodstone is its chatoyancy, or the cat's-eye effect, which can occur when the hematite inclusions are aligned in a single direction. This effect is rare but highly valued in certain markets.
Bloodstone is also known for its durability, though it is more prone to scratching than aquamarine. It is non-fluorescent and does not typically require treatment to enhance its appearance.
Symbolism and Metaphysical Beliefs
Aquamarine
Aquamarine has long been associated with the sea, and its calming blue color has made it a symbol of tranquility and serenity. Ancient sailors believed that aquamarine could protect them from the dangers of the ocean, and it was often carried as a talisman for safe passage. This belief has persisted into modern times, with aquamarine being used in jewelry for those seeking protection and calm in their daily lives.
In addition to its protective qualities, aquamarine is believed to bring clarity of thought and emotional balance. It is often used in crystal healing to help reduce stress, enhance communication, and bring inner peace. The gemstone is also associated with courage and loyalty, making it a fitting birthstone for those born in March.
Aquamarine is also linked to the zodiac signs Pisces and Aries, reflecting its dual nature of calm and courage. It is believed to help Pisces individuals connect with their emotions and express themselves more freely, while helping Aries individuals find balance and control.
Bloodstone
Bloodstone, with its deep green base and red speckles, has long been associated with strength, vitality, and courage. The red spots of iron oxide, which resemble drops of blood, have led to its use in healing and protection. In ancient times, bloodstone was believed to have the power to heal wounds and prevent disease. It was also used in amulets and talismans to ward off evil and bring good fortune.
In the Middle Ages, bloodstone was believed to have purifying properties, and it was used in medicinal practices to treat blood-related ailments. It was also used in religious ceremonies, particularly in the Christian tradition, where it was associated with the Passion of Christ.
Modern metaphysical beliefs continue to associate bloodstone with physical and emotional strength. It is believed to help those who struggle with anxiety, fear, and self-doubt, and it is often used in healing practices to promote courage and resilience. Bloodstone is also believed to enhance the immune system and improve circulation, making it a popular gemstone in the wellness and healing communities.
Care and Cleaning
Aquamarine
Due to its hardness of 7.5–8 on the Mohs scale, aquamarine is relatively durable and can be cleaned with mild soap and warm water. It is non-reactive to most household chemicals, so it can be safely cleaned using a soft brush and a gentle cleanser.
Aquamarine should be stored separately from harder gemstones to prevent scratches. It is also advisable to avoid exposure to extreme heat, as this can cause the gemstone to fade or become discolored. Aquamarine is not typically sensitive to light, but it should be stored in a cool, dark place when not in use to preserve its color and clarity.
Bloodstone
Bloodstone has a hardness of 6.5–7 on the Mohs scale, making it less durable than aquamarine. It should be cleaned with mild soap and warm water, using a soft cloth or brush to avoid scratching the surface. Bloodstone is susceptible to scratches and abrasions, so it should be stored separately from harder gemstones.
Bloodstone is also non-reactive to most household chemicals, but it should be avoided to use harsh cleaners or ultrasonic cleaners, as these can damage the gemstone. Bloodstone should be stored in a cool, dry place to prevent dulling or discoloration.
