March is a month of transition, marking the beginning of spring in the Northern Hemisphere and the return of life and renewal. For those born in this dynamic month, the tradition of birthstones offers a symbolic connection to the world around them. March is unique in that it is associated with two primary birthstones: aquamarine and bloodstone. These gemstones, though differing in appearance and properties, share a common theme of protection and well-being, making them both deeply meaningful to those who choose to wear them.
This article delves into the rich history, gemological properties, cultural significance, and practical care of aquamarine and bloodstone. Drawing from authoritative and historical sources, we explore how these gems have been valued across centuries, and why they remain cherished today.
Introduction
March-born individuals are indeed spoiled for choice, as their birthstone options extend beyond the traditional pair of aquamarine and bloodstone. Other stones like ruby, emerald, jade, and crystal are also linked to March in various birthstone traditions, including those related to zodiac signs and spiritual guardians. However, aquamarine and bloodstone remain the most widely recognized and historically significant.
The duality of these two gemstones reflects the multifaceted nature of March itself: aquamarine, with its tranquil blue hues and association with the sea, and bloodstone, with its deep green and red flecks, symbolizing strength and vitality. This article will explore the origins and legends surrounding both gemstones, their physical and chemical characteristics, and their enduring presence in jewelry and cultural traditions.
History and Lore
The Origins of March Birthstones
The tradition of associating gemstones with the months of the year has ancient roots, dating back to the 1st century AD. Early scholars linked the 12 gemstones of the High Priest’s breastplate from the Old Testament to the 12 zodiac signs and the 12 months of the year. This connection laid the foundation for the birthstone traditions that persist today.
In early versions of these lists, bloodstone was the only designated birthstone for March. Bloodstone, a form of chalcedony, was valued for its deep green color and red iron oxide flecks, which were believed to symbolize the blood of Christ in Christian lore. The gem was thought to bring courage and vitality to the wearer.
However, as gemology advanced and more accurate identification methods became available, the list of birthstones expanded. By the 18th and 19th centuries, aquamarine—a member of the beryl family—was added to the March birthstone list. Aquamarine’s calming blue color and transparent quality made it a natural complement to bloodstone, and both were eventually recognized as the official March birthstones.
The modern standardized list of birthstones is often credited to jewelers in Germany and Poland in the 1500s, who began selling jewelry set with gemstones corresponding to the wearer’s birth month. By the 1800s, the tradition had gained widespread popularity, and in 1870, Tiffany & Co. published a list of birthstone poems, further cementing these associations in the public consciousness.
Cultural Significance
Both aquamarine and bloodstone have been revered for their protective qualities. Aquamarine was believed by ancient mariners to calm the seas and protect sailors on long voyages. It was also seen as a symbol of purity and was often used in engagement rings to represent constancy in love.
Bloodstone, on the other hand, was associated with physical strength and endurance. In medieval Europe, it was worn by knights and warriors to increase their courage and protect them in battle. The gemstone’s name is derived from the Greek word heliotrope, meaning “turning with the sun,” and was thought to bring vitality and healing to the wearer.
In more recent times, both aquamarine and bloodstone have been incorporated into modern jewelry design, often used as center stones in rings, pendants, and bracelets. Their contrasting colors and properties make them versatile options for both casual and formal wear.
Geological Formation and Sources
Aquamarine
Aquamarine is a variety of the mineral beryl, a beryllium aluminum silicate with the chemical formula Be₃Al₂(SiO₃)₆. Its color ranges from a pale blue to a deep blue-green, caused by trace amounts of iron in the crystal structure. Aquamarine is relatively hard, ranking 7.5 to 8 on the Mohs scale, making it durable enough for everyday wear, though it should still be protected from impacts.
Aquamarine forms in igneous rocks, particularly in granite pegmatites and metamorphic rocks. It is typically found in large, well-formed crystals, which can be cut into faceted gems or used as collector's specimens. The largest aquamarine crystals ever discovered were found in Brazil, where the gemstone is still one of the most important sources today.
Significant sources of aquamarine include:
- Brazil – The most important and prolific source, with large, high-quality stones found in the states of Minas Gerais and Bahia.
- Nigeria and Madagascar – These countries produce high-quality aquamarine with excellent clarity.
- Afghanistan and Pakistan – Smaller but notable sources of aquamarine with unique colors.
Aquamarine is often heat-treated to enhance its color, particularly to remove any greenish tinge and intensify the blue. This treatment is generally stable and does not affect the gemstone's durability.
Bloodstone
Bloodstone, also known as heliotrope, is a type of chalcedony, a microcrystalline variety of quartz. Its base color is a deep green, and it is distinguished by the presence of red iron oxide flecks, which resemble drops of blood. These flecks are responsible for the gemstone's name and its historical association with healing and vitality.
Bloodstone is relatively soft compared to aquamarine, with a Mohs hardness of 6.5 to 7, and is usually cut as a cabochon (a smooth, rounded surface without facets). This cut enhances the stone’s chatoyancy and the visibility of the red flecks.
The formation of bloodstone occurs in sedimentary and metamorphic rocks, often in association with other chalcedony varieties like agate and jasper. The presence of iron oxide is what gives the stone its characteristic red spots.
Significant sources of bloodstone include:
- India – Known for producing high-quality bloodstone with vivid red flecks.
- Nepal and Pakistan – These countries also yield excellent bloodstone, often used in traditional jewelry and carvings.
- Brazil and the United States – Bloodstone is found in these countries as well, though it is less commonly exported in large quantities.
Bloodstone is not typically treated, as its natural coloration is stable and attractive. However, some lower-quality stones may be dyed to enhance the red spots or to deepen the green color.

Both aquamarine and bloodstone have long been associated with various spiritual and metaphysical properties, though these beliefs vary across cultures and historical periods.
Aquamarine
Aquamarine has been regarded as a stone of calmness and clarity. Ancient mariners believed it could protect them from the dangers of the sea, and it was often carried on long voyages to ensure safe passage. In medieval times, it was thought to bring intellectual clarity and was worn by scholars and students to enhance their focus and understanding.
Modern metaphysical traditions continue to associate aquamarine with emotional balance and communication. It is said to help the wearer overcome fear and anxiety, and to encourage honesty and self-expression. Aquamarine is also believed to promote harmony in relationships, making it a popular choice for engagement rings and wedding jewelry.
From a spiritual perspective, aquamarine is linked to the Throat Chakra, which governs communication and self-expression. Wearing aquamarine is believed to support the wearer in expressing their thoughts and emotions clearly and with confidence.

It was also thought to increase the wearer’s endurance and courage, making it a popular choice for warriors and athletes.
Bloodstone is considered a grounding stone, helping to stabilize emotions and promote a sense of inner strength. It is often used in meditation to enhance focus and mental clarity. In some traditions, it is believed to help the wearer overcome addictions and unhealthy habits by strengthening willpower and determination.
Spiritually, bloodstone is linked to the Root Chakra, which is associated with physical strength, survival, and a strong connection to the earth. It is also connected to the Heart Chakra, symbolizing compassion, love, and the ability to forgive.
Care and Cleaning
Proper care and cleaning are essential for preserving the beauty and longevity of both aquamarine and bloodstone. While both gemstones are relatively durable, they do have different requirements due to their varying hardness and structure.
Aquamarine Care
Aquamarine is a hard and durable gemstone, but it should still be protected from sudden impacts and exposure to harsh chemicals. To clean aquamarine jewelry, use a soft cloth and warm, soapy water. A soft-bristled brush can be used to gently remove dirt from the gemstone and surrounding metal settings.
Aquamarine should be stored separately from other gemstones to prevent scratches. It can be exposed to light, but prolonged exposure to direct sunlight may cause the color to fade slightly over time.
Bloodstone Care
Bloodstone is softer than aquamarine and should be handled with more care. It is not recommended to use ultrasonic cleaners or steam cleaners on bloodstone, as these can cause damage to the stone or the surrounding metal.
To clean bloodstone, use a soft cloth and warm, soapy water. Avoid using abrasive cleaners or harsh chemicals, as these can dull the stone’s surface. Bloodstone should be stored in a soft pouch or box to prevent scratches from harder gemstones.
Both gemstones should be inspected regularly for loose settings and cleaned as needed to maintain their appearance.
