Aquamarine, a member of the beryl family, is known for its durability and ethereal color, often found in jewelry that emphasizes purity and emotional clarity. Bloodstone, a type of chalcedony, is distinguished by its inclusions of hematite that resemble drops of blood, lending it a powerful presence in both historical and contemporary contexts.
This article explores the geological, cultural, and symbolic dimensions of both aquamarine and bloodstone. It covers their formation, properties, historical uses, and the meanings ascribed to them across time. Additionally, it addresses care and maintenance tips for each stone, ensuring they remain beautiful and meaningful for generations.
History and Lore
The Ancient Roots of March Birthstones
The origins of birthstones are intertwined with ancient beliefs and practices that connected gemstones to celestial bodies, human traits, and natural forces. For March, both aquamarine and bloodstone have been valued across different cultures for centuries.
Aquamarine’s name is derived from the Latin words aqua (water) and marina (of the sea), a fitting description for a gemstone that evokes the ocean. Ancient mariners and sailors believed that carrying aquamarine would protect them from the perils of the sea, calming the waves and ensuring safe passage. This belief was reinforced by the stone’s clear, watery appearance. The ancient Romans also associated aquamarine with Bellerophon, a mythological hero who tamed the winged horse Pegasus while holding an aquamarine.
Bloodstone, on the other hand, has a more terrestrial symbolism. The red inclusions in bloodstone were historically interpreted as drops of blood, and the stone was believed to promote vitality, courage, and even the healing of physical wounds. In medieval Europe, it was often used in rings and pendants as a protective charm for warriors and knights. The stone’s association with blood and life force made it a powerful symbol of strength and endurance.
Both gemstones have been used in jewelry and amulets since ancient times, and their meanings have evolved alongside human history. In the 19th century, aquamarine became a popular choice for engagement rings and was also designated as a commemorative stone for the 19th wedding anniversary. Bloodstone, meanwhile, was often worn by those seeking protection during battle or illness, and it was believed to help the wearer remain steadfast in difficult times.
The Modern Recognition of March Birthstones
The modern standardized list of birthstones was established in the early 20th century. In 1912, the National Association of Jewellers (now known as the Jewelers of America) created a formalized list to help consumers understand the symbolic and historical significance of gemstones associated with each month. March was assigned both aquamarine and bloodstone, recognizing the historical importance of both stones.
In 1952, the list was updated by the Jewelry Industry Council of America, which continued to include both aquamarine and bloodstone for March. While some variations exist in different countries and cultures, the British and American lists prioritize aquamarine as the primary March birthstone, with bloodstone as a secondary or traditional option.
The dual designation of March’s birthstone reflects the diverse ways in which people have connected with these gemstones over time. Aquamarine is often favored in contemporary jewelry for its vibrant yet calming color and its association with emotional balance and clarity. Bloodstone, while less commonly used in modern fashion, still holds a place in alternative and historical jewelry traditions, particularly in pieces that emphasize strength and resilience.
Geological Formation and Sources
Aquamarine: A Beryl of the Sea
Aquamarine is a variety of the mineral beryl, which also includes the famous gemstone emerald. It is composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆) and owes its blue and blue-green coloration to trace amounts of iron. The presence of iron in different oxidation states can result in a range of hues, from pale sea green to deep ocean blue.
Aquamarine is typically found in granite pegmatites, which are igneous rocks that form under high temperature and pressure conditions. The formation process involves the slow crystallization of magma, allowing for the growth of large, high-quality crystals. Inclusions of other minerals or gases can lead to interesting visual effects, such as chatoyancy (a cat’s eye effect) or asterism (a star-like pattern), though these are rare in aquamarine.
Some of the most notable sources of aquamarine include Brazil, Nigeria, and Madagascar. Brazil, in particular, is known for producing high-quality aquamarine with excellent clarity and color. The Santa Maria mine in Brazil is famous for its rich deposits of aquamarine, especially the highly prized "Santa Maria" variety, which features a medium-dark, high-saturation blue color.
Aquamarine is a relatively durable gemstone, ranking between 7.5 and 8 on the Mohs hardness scale. This makes it suitable for use in various types of jewelry, including rings, earrings, and pendants. Its transparency and lack of inclusions also make it ideal for faceting, allowing for maximum light return and brilliance.
Bloodstone: The Stone of Vitality
Bloodstone is a type of chalcedony, a microcrystalline variety of quartz. It is composed primarily of silicon dioxide (SiO₂), with inclusions of hematite (iron oxide), which give the stone its distinctive red spots. The name "bloodstone" comes from the appearance of these inclusions, which resemble drops of blood scattered across the dark green matrix.
The formation of bloodstone occurs through sedimentary processes, where chalcedony deposits are enriched with iron. Over time, the iron oxidizes, creating the red inclusions that define the stone. Bloodstone is typically opaque, meaning it is not transparent like aquamarine, and it is most commonly cut as a cabochon rather than being faceted.
India is the primary source of high-quality bloodstone, particularly the state of Rajasthan, which has been a major producer for centuries. Other notable sources include Brazil, the United States, and parts of Europe. Bloodstone is generally more accessible and affordable than aquamarine, making it a popular choice for those seeking a meaningful and symbolic gemstone at a lower cost.
On the Mohs scale, bloodstone ranks between 6.5 and 7, making it slightly less durable than aquamarine. It is best suited for jewelry that is worn occasionally rather than daily, as it can be more prone to scratches and abrasions.
Gemological Properties
Aquamarine
| Property | Description |
|---|---|
| Chemical Formula | Be₃Al₂(SiO₃)₆ |
| Hardness (Mohs) | 7.5–8 |
| Color | Blue to blue-green |
| Transparency | Transparent to slightly included |
| Refractive Index | 1.57–1.58 |
| Luster | Vitreous |
| Crystal System | Hexagonal |
| Common Cuts | Faceted (especially emerald, round, oval) |
| Common Inclusions | Negative crystals, gas bubbles, or iron-rich inclusions |
Aquamarine’s most notable gemological feature is its range of blue hues, which are caused by the presence of iron. The most highly valued aquamarines are those with a pure blue color and minimal inclusions. The presence of inclusions can actually enhance the stone’s character, especially if they contribute to a chatoyant or asteriated effect.
The refractive index of aquamarine is relatively low compared to other colored gemstones, which gives it a subtle, gentle sparkle. This makes it ideal for those who prefer a more understated gemstone with a soft, oceanic glow. Aquamarine is also heat-sensitive, so it should not be exposed to high temperatures during jewelry manufacturing or repair.
Bloodstone
| Property | Description |
|---|---|
| Chemical Formula | SiO₂ (with inclusions of hematite) |
| Hardness (Mohs) | 6.5–7 |
| Color | Dark green with red inclusions |
| Transparency | Opaque |
| Refractive Index | 1.48–1.53 |
| Luster | Waxy to vitreous |
| Crystal System | Trigonal |
| Common Cuts | Cabochon |
| Common Inclusions | Hematite (iron oxide) |
Bloodstone is a microcrystalline quartz with a waxy to vitreous luster. The red inclusions are typically in the form of small, rounded spots or flecks, which are actually tiny crystals of hematite. These inclusions are not only responsible for the stone’s name but also contribute to its unique visual character.
Because bloodstone is opaque, it is not faceted but instead cut as a cabochon, which enhances its smooth, even surface and allows for the full display of its inclusions. The refractive index is lower than that of aquamarine, and the stone does not exhibit any optical effects like chatoyancy or asterism.
Bloodstone is relatively stable under normal conditions but should be protected from harsh chemicals and extreme temperatures. It is also sensitive to ultrasonic cleaners, which can damage the stone’s surface or remove its polish.
Symbolism and Metaphysical Beliefs
Aquamarine: The Stone of Clarity and Calm
Aquamarine has long been associated with emotional and mental clarity. In many cultures, it is believed to promote tranquility, helping the wearer to remain calm and composed in times of stress. This makes it a popular stone for those seeking peace of mind or emotional balance.
In medieval Europe, aquamarine was believed to protect against poisoning and to enhance the health of the eyes. Sailors carried it to ward off the dangers of the sea, and it was also used in amulets to bring good fortune and safe travel.
In modern metaphysical practices, aquamarine is thought to open the throat chakra, enhancing communication and self-expression. It is also associated with the water sign Pisces and is believed to help those with sensitive or artistic natures to navigate their emotions with grace and understanding.
Bloodstone: The Stone of Vitality and Courage
Bloodstone has been traditionally used as a protective stone, particularly for warriors and those in battle. It was believed to strengthen the body and mind, giving the wearer the courage to face challenges and overcome adversity. In medieval Europe, bloodstone was often worn by knights and soldiers as a symbol of bravery and strength.
The red inclusions in bloodstone were seen as symbolic of life force and vitality. Some cultures believed that the stone could help in the healing of wounds and the recovery from illness. It was also used in rings and pendants as a talisman to promote physical and mental resilience.
In modern metaphysical practices, bloodstone is associated with the root chakra and is believed to ground the wearer, promoting a sense of stability and connection to the earth. It is also used to support those undergoing physical or emotional healing and is considered a powerful stone for those seeking strength and endurance.
