The gemstone associated with the month of March is Aquamarine, a gem celebrated for its tranquil, sea-blue hues and remarkable clarity. As the primary modern birthstone for March, Aquamarine captures the essence of the ocean, embodying qualities of calmness, purity, and courage. Its name, derived from the Latin words aqua (water) and marina (sea), perfectly describes its signature color, which ranges from the palest sky blue to deep, saturated azure. While Aquamarine stands as the contemporary choice, the month also honors the traditional birthstone, Bloodstone, a dark green chalcedony speckled with red, representing a different but equally powerful form of March-born vitality.
This article provides a comprehensive exploration of Aquamarine, delving into its historical lore, geological origins, distinct gemological properties, and the metaphysical beliefs that have surrounded it for centuries. We will also examine the traditional significance of Bloodstone and offer practical guidance on the care and maintenance of these precious stones. For the gemstone enthusiast, the jewelry buyer, and the student of gemology, understanding Aquamarine is to appreciate a gem that is as scientifically fascinating as it is culturally rich.
History and Lore
The history of Aquamarine is deeply intertwined with humanity's relationship with the sea. Ancient civilizations revered this gem not merely for its beauty but for the protective powers they believed it held. Roman fishermen and sailors were among its earliest devotees, carrying Aquamarine talismans on their voyages. They believed the gem could calm stormy seas, ensure a safe passage, and protect them from drowning. This belief was so pervasive that Aquamarine was often inscribed with the image of Neptune, the Roman god of the sea, to amplify its protective qualities.
The lore surrounding Aquamarine extends beyond maritime protection. In ancient times, it was believed to be a treasure of mermaids and was used by sailors as a lucky charm and an antidote to seasickness. The gem was also associated with the element of water and was thought to possess purifying properties, capable of cleansing the spirit and promoting clarity of thought. Ancient healers and mystics used Aquamarine in rituals intended to reawaken love, foster marital happiness, and inspire trust and fidelity.
The journey of Aquamarine from a humble sailor's stone to a prized gem in royal and aristocratic collections is a testament to its enduring appeal. As cutting and polishing techniques improved, the gem's inherent brilliance and clarity could be fully showcased, elevating its status from a folk charm to a jewel of significant value. Its association with the zodiac sign of Pisces (February 19 - March 20) further solidified its cosmic connection to the watery realm, aligning its calming energies with the intuitive and empathetic nature of this sign.
Bloodstone, the traditional March birthstone, carries a history just as potent, though markedly different in character. Also known as Heliotrope, this cryptocrystalline quartz was revered by ancient Greeks and Romans, who associated it with the god of the sun, Helios. Its most famous legend stems from the crucifixion of Christ, where it was said that the blood from his wounds dripped onto the dark green stone at the foot of the cross, imbuing it with sacred power. This story led to its use in the Middle Ages for carving scenes of the crucifixion. Bloodstone was not a gem of tranquility but one of strength, courage, and vitality—a warrior's stone. It was believed to heal wounds, stop bleeding, and bring victory in battle, making it a powerful amulet for soldiers and a symbol of resilience.
Geological Formation and Sources
Aquamarine is a member of the beryl mineral family, making it a cousin to other well-known gems like emerald (green beryl), morganite (pink beryl), and heliodor (yellow beryl). Its beautiful blue color is the result of trace amounts of iron within its crystal structure. The specific shade of blue is determined by the oxidation state of the iron ions present during its formation.
This gemstone forms in large, hexagonal crystals within igneous and metamorphic rocks, particularly in pegmatites—coarse-grained rocks that allow for the growth of exceptionally large and well-formed crystals. The geological conditions must be just right: a slow cooling process and the presence of water-rich fluids carrying beryllium, aluminum, silicon, and the necessary trace elements. These fluids seep into cavities and fractures in the host rock, where, over millions of years, they crystallize into the magnificent hexagonal pillars of beryl.
While Aquamarine can be found in various locations around the world, certain regions are renowned for producing the highest quality stones. Brazil is the world's leading source of Aquamarine, particularly from the states of Minas Gerais and Bahia, where massive crystals are frequently unearthed. Other significant sources include Madagascar, Nigeria, Zambia, and Pakistan, with the latter country known for producing intensely colored, deep blue crystals from the Skardu region. The United States also has a notable source in the state of Maine, which designated Aquamarine as its official state gemstone in 1971.
Bloodstone, on the other hand, is a variety of chalcedony, which is a microcrystalline form of quartz (silicon dioxide). It is composed of dark green jasper (an impure form of chalcedony) with inclusions of iron oxides, typically red hematite, which give the stone its characteristic "blood-like" spots. Bloodstone is found in various locations, including India, Brazil, Australia, and parts of Africa and Europe. It forms in volcanic or metamorphic rocks under conditions that allow for the deposition of silica-rich fluids.
Gemological Properties
Understanding the physical and chemical properties of a gemstone is crucial for both identification and appreciation. Aquamarine and Bloodstone, while both associated with March, belong to different mineral families and possess distinct characteristics.
Aquamarine (Beryl)
As a member of the beryl family, Aquamarine is prized for its hardness and excellent clarity.
- Chemical Composition: Be₃Al₂Si₆O₁₈ (Beryllium Aluminum Silicate) with traces of Iron (Fe)
- Crystal System: Hexagonal
- Hardness (Mohs Scale): 7.5 - 8. Aquamarine is a durable gemstone, making it suitable for all types of jewelry, including rings that are worn daily. It is harder than most other blue gemstones like topaz (8) and significantly harder than stones like lapis lazuli (5-6).
- Refractive Index: 1.577 - 1.583
- Specific Gravity: 2.68 - 2.70
- Luster: Vitreous (glass-like)
- Clarity: Aquamarine is known for its "eye-clean" clarity, meaning high-quality stones are typically free of visible inclusions to the naked eye. Inclusions, when present, can sometimes resemble liquid "fingerprints" or fine needles.
- Color: Ranges from very light blue to a deep, saturated blue. The most valued color is a deep, pure blue with a slight hint of green, often referred to as "Santa Maria" color, named after a famous Brazilian mine. Most commercially available Aquamarine is a light blue, as larger, darker stones are rarer and command higher prices.
Bloodstone (Heliotrope)
Bloodstone is a variety of chalcedony, a member of the quartz family. Its properties are different from those of Aquamarine.
- Chemical Composition: SiO₂ (Silicon Dioxide) with inclusions of Iron Oxide (Hematite)
- Crystal System: Trigonal (microcrystalline)
- Hardness (Mohs Scale): 6.5 - 7. While still relatively durable, it is slightly less hard than Aquamarine.
- Refractive Index: 1.530 - 1.540
- Specific Gravity: 2.58 - 2.64
- Luster: Waxy to vitreous when polished.
- Clarity: Opaque. Transparency is not a characteristic of Bloodstone; its appeal lies in its rich color and the contrast between the dark green base and the red inclusions.
- Color: Dark, earthy green with distinct red spots.

Symbolism and Metaphysical Beliefs
The symbolic meanings attached to Aquamarine and Bloodstone are as distinct as their physical appearances, offering March-born individuals a choice between two powerful archetypes: the serene healer and the courageous warrior.
Aquamarine is overwhelmingly associated with tranquility, clarity, and emotional balance. Its connection to the sea lends it an aura of fluidity and purification. In modern metaphysical beliefs, it is known as a "Stone of Courage," but its courage is not of the battlefield; it is the courage to speak one's truth, to navigate emotional turmoil with calm, and to connect with one's innermost feelings. It is believed to soothe the mind, reduce stress, and quiet scattered thoughts, making it an excellent aid for meditation. For those born under the sign of Pisces, it is said to enhance their natural intuition and empathy while providing a protective barrier against emotional overwhelm. Aquamarine is also considered a stone of eternal youth and happiness, and it is often given as a gift to symbolize love, commitment, and trust.
Bloodstone, in contrast, is a talisman of strength, vitality, and practical action. Its symbolism is rooted in the earth and the physical body. It is known as the "Stone of the Martyr" for its legendary association with Christ's blood, but it is also a "Warrior's Stone," believed to instill courage, enhance endurance, and provide protection from physical harm and negative energies. Where Aquamarine calms, Bloodstone energizes. It is associated with the root chakra, grounding the wearer and connecting them to the life force of the planet. Metaphysical practitioners use Bloodstone to purify the blood, boost the immune system, and overcome feelings of lethargy or victimhood. It is a stone for those who need to take charge, make decisive choices, and persevere through adversity.
Care and Cleaning
Proper care is essential to maintain the beauty and longevity of any gemstone jewelry. The different hardness levels and chemical compositions of Aquamarine and Bloodstone dictate specific cleaning and storage guidelines.
Caring for Aquamarine
With a hardness of 7.5 to 8, Aquamarine is quite durable and resistant to scratching by most everyday materials. However, it can be damaged by sharp blows or extreme temperature changes.
- Cleaning: The safest method for cleaning Aquamarine is warm, soapy water with a soft brush (like a toothbrush). Gently scrub the back and sides of the stone to remove any accumulated oils or dirt. Rinse thoroughly with clean water. Avoid ultrasonic cleaners, as the vibrations can potentially damage the stone if it has liquid inclusions. Steam cleaning is also not recommended. For a quick refresh, a simple wipe with a soft, lint-free cloth can be effective.
- Storage: When storing Aquamarine jewelry, keep it in a soft pouch or a separate compartment in a jewelry box. While Aquamarine is hard, it can be scratched by other gemstones with a higher or similar hardness, such as diamonds, sapphires, and rubies. It is best to store it away from direct sunlight for prolonged periods, as intense heat and light can cause some lighter-colored stones to fade slightly, although this effect is generally minimal.
Caring for Bloodstone
Bloodstone, at 6.5 to 7 on the Mohs scale, is still reasonably durable but requires slightly more care than Aquamarine. Its main vulnerability is its potential for chipping along cleavage planes and its reaction to harsh chemicals.
- Cleaning: Like Aquamarine, Bloodstone should be cleaned using warm, soapy water and a soft brush. It is crucial to avoid any harsh chemicals, including household cleaners, bleach, and strong acids, which can damage the stone's surface and dull its polish. Ultrasonic and steam cleaners should be avoided, as they can cause damage.
- Storage: Store Bloodstone pieces separately in a soft cloth or padded jewelry box to prevent them from being scratched by harder stones or from chipping if knocked against a hard surface.
