The Color of March Birthstones: Aquamarine and Bloodstone

March is uniquely associated with two birthstones—aquamarine and bloodstone—each with its own striking color, historical significance, and symbolic meaning. While these gemstones differ dramatically in appearance and composition, both have long been revered for their beauty and their roles in cultural traditions. The color of the March birthstones is not only a defining feature of their visual appeal but also a key factor in their historical and metaphysical associations.

This article delves into the color properties, origins, and symbolism of aquamarine and bloodstone, the two birthstones of March. We will explore how their colors have influenced their uses in jewelry, their roles in ancient traditions, and what makes them stand out in the world of gemstones.


History and Lore

The tradition of birthstones dates back to the 1st century AD, when early historians linked the 12 stones mentioned in the biblical Breastplate of Aaron to the 12 months of the year and the 12 zodiac signs. Initially, bloodstone was the sole birthstone associated with March. However, as gem identification and jewelry craftsmanship evolved over centuries, aquamarine was added to the list, reflecting a broader and more nuanced understanding of gemstones and their properties.

The bloodstone, with its deep forest green color and distinctive red flecks of iron oxide, was believed to symbolize life and vitality. Ancient cultures, including the Greeks and Romans, associated the red inclusions with the blood of Christ, believing the gemstone could promote courage and strength. It was also thought to have healing properties and was often used in amulets and talismans.

In contrast, aquamarine, named from the Latin aqua marina (meaning “sea water”), has long been connected to the ocean. Ancient mariners carried aquamarine with them on long voyages, believing it would calm the seas and protect them from the wrath of Poseidon. The gem was also considered a symbol of happiness in marriage and was thought to bestow clarity of thought and bravery upon the wearer.

The addition of aquamarine to the March birthstone tradition is also linked to its growing popularity in the 19th century. As mining techniques improved and larger, clearer specimens became available, aquamarine gained favor among jewelers and collectors. By the late 1800s, it had become a widely recognized and accepted birthstone for March, often worn alongside bloodstone.


Geological Formation and Sources

Both aquamarine and bloodstone are formed through different geological processes, which influence their colors and physical properties.

Aquamarine

Aquamarine is a variety of beryl, a mineral composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆). Its signature blue or blue-green color is caused by trace amounts of iron within the crystal structure. In its purest form, beryl is colorless, but the presence of different trace elements can produce a range of colors, including the green of emerald, the yellow of heliodor, and the pink of morganite.

Aquamarine is typically found in pegmatite rock formations, which are coarse-grained igneous rocks that form from the slow cooling of magma. These environments allow for the growth of large, well-formed crystals, which is why aquamarine is often found in substantial sizes.

The most important sources of aquamarine include:

  • Brazil – The largest and highest-quality aquamarine is mined in Brazil, particularly in the states of Minas Gerais, Bahia, and Espírito Santo.
  • Colombia – Known for producing high-quality aquamarine with vibrant blue tones.
  • Russia (Ural Mountains) – A historical source of aquamarine, though production is now limited.
  • Madagascar – Produces stones with a wide range of colors, from pale blue to deep greenish-blue.
  • United States – States like Colorado, Maine, and North Carolina have notable aquamarine deposits.
  • India – A significant producer of aquamarine, particularly in the state of Rajasthan.

Aquamarine is generally transparent to translucent, with a Mohs hardness of 7.5 to 8, making it durable enough for everyday wear. It is also pleochroic, meaning it can display different colors depending on the angle from which it is viewed. This phenomenon is due to the crystal structure of beryl and can cause the stone to appear more green, blue, or even colorless at different angles.

Bloodstone

Bloodstone, also known as heliotrope, is a chalcedony—a form of microcrystalline quartz—characterized by its deep green background with red spots or flecks of iron oxide. The green color is typically caused by chlorite or other iron-bearing minerals embedded within the stone, while the red inclusions are iron oxide, which resembles blood.

Bloodstone is often found in sedimentary rocks, particularly in basalt and volcanic rock formations. These environments provide the necessary conditions for the development of chalcedony with iron oxide inclusions.

Key sources of bloodstone include:

  • India – One of the largest and most consistent producers of bloodstone, particularly in the state of Rajasthan.
  • Nepal – Known for producing high-quality bloodstone with vivid red inclusions.
  • United States – Bloodstone is found in states like California and Oregon, though not as prominently as in India or Nepal.
  • France and Germany – Historically important sources, though production has declined in recent years.

Bloodstone is typically opaque to translucent, with a Mohs hardness of 6.5 to 7, making it suitable for jewelry, particularly as cabochons (smooth, domed stones). It is often used in rings, pendants, and beads, where its vibrant color and symbolic meaning are highlighted.


Symbolism and Metaphysical Beliefs

Both aquamarine and bloodstone have long been associated with powerful symbolic and metaphysical properties, many of which are rooted in ancient traditions and folklore.

Aquamarine

Aquamarine has been revered for its calming and protective qualities. Ancient mariners believed that carrying aquamarine would calm the seas and protect them from storms and shipwrecks. The gemstone was also associated with happiness in marriage, and it was thought to promote clarity of thought and courage.

In modern metaphysical beliefs, aquamarine is considered a stone of serenity and peace. It is believed to help reduce anxiety, ease stress, and promote emotional healing. Some also believe it enhances communication and truth, making it a popular choice for those seeking to improve their verbal and written expression.

Aquamarine is also linked to physical healing, particularly in relation to the thyroid, throat, and respiratory system. It is believed to help with allergies, asthma, and other throat-related ailments, though these claims are not supported by scientific evidence.

Bloodstone

Bloodstone is known for its energetic and protective properties. In ancient times, it was believed to promote strength, courage, and vitality, and it was often used as a healing amulet. The red inclusions were thought to symbolize blood, and the gemstone was believed to help replenish blood and improve circulation.

In modern metaphysical practices, bloodstone is considered a stone of vitality and grounding. It is believed to help increase energy, stamina, and endurance, making it a popular choice for athletes and those seeking to improve their physical health. It is also associated with emotional balance, particularly in helping to reduce anger, aggression, and impatience.

Bloodstone is also used in spiritual practices, particularly in rituals involving protection, purification, and strength. It is often worn during times of change or challenge, as it is believed to provide stability and support during difficult transitions.


Care and Cleaning

Proper care and cleaning are essential to maintaining the beauty and longevity of aquamarine and bloodstone.

Aquamarine

Aquamarine is relatively durable, with a Mohs hardness of 7.5 to 8, making it suitable for daily wear. However, it is not resistant to fractures or cleavage, so it should be handled with care to avoid damage.

  • Cleaning: Aquamarine can be cleaned with mild soap and warm water or with a professional ultrasonic cleaner. Avoid using harsh chemicals or abrasive materials, as they can scratch the surface of the stone.
  • Storage: Store aquamarine separately from harder gemstones to prevent scratches. It is best to wrap the stone in a soft cloth or place it in a jewelry box with individual compartments.
  • Avoid exposure: Prolonged exposure to direct sunlight or heat can cause the color of aquamarine to fade or become uneven. It is best to store it in a cool, dark place when not in use.

Bloodstone

Bloodstone is slightly less durable than aquamarine, with a Mohs hardness of 6.5 to 7. It is also opaque and porous, which makes it more susceptible to staining and absorption of oils.

  • Cleaning: Bloodstone can be cleaned with mild soap and warm water or with a soft cloth and a gentle jewelry cleaner. Avoid using harsh chemicals, abrasive materials, or ultrasonic cleaners, as they can damage the surface of the stone.
  • Storage: Store bloodstone separately from harder gemstones to avoid scratches. It is best to wrap it in a soft cloth or place it in a jewelry box with individual compartments.
  • Avoid exposure: Bloodstone is porous, so it should be kept away from oils, lotions, and perfumes, which can stain the stone. It is also best to avoid prolonged exposure to direct sunlight, as it can cause the color to fade.
