This article explores the origins, geological formation, scientific properties, and enduring symbolism of amethyst and aquamarine, drawing on historical and gemological data to provide a comprehensive guide for enthusiasts and collectors.
History and Lore
Amethyst: The Stone of Sobriety and Clarity
Amethyst, the primary birthstone for February, boasts a history that spans millennia. Its name is derived from the Greek word amethystos, meaning "not drunk." This etymology reflects a central ancient belief: that wearing amethyst could prevent intoxication. Historical accounts note that ancient Greeks and Romans often drank wine from amethyst goblets, convinced the gemstone would protect them from alcohol's effects. Beyond its association with sobriety, amethyst was also believed to ward off evil and promote mental clarity and calmness.
The gemstone’s popularity surged during the Roman Empire, where it was frequently used in signet rings and cameos. By the Middle Ages, amethyst was considered a sacred stone and was closely associated with the Catholic Church, often appearing in ecclesiastical jewelry. Greek mythology further enriched its lore, suggesting that amethyst was created when the god Dionysus wept over a young maiden turned to quartz; his tears stained the stone purple, giving birth to the gem. In medieval times, February’s birthstone was worn by royalty as a symbol of power, purity, and divine connection. Across various cultures, amethyst was believed to possess the power to ward off evil, enhance intelligence, and bring a sense of tranquility.
Aquamarine and Bloodstone: The Dual March Birthstones
March is unique in having two traditional birthstones: aquamarine and bloodstone. The month itself is named after Mars, the Roman god of war, reflecting a time when soldiers resumed campaigns after winter. This period also marked the return to farming and travel, with festivals celebrating the new year and the spring equinox. Today, March symbolizes new beginnings, rebirth, and hope.
Aquamarine derives its name from the Latin aqua marina, meaning "sea water," a direct reference to its captivating blue color, which ranges from pale to deep blue. Historically, aquamarine was associated with the sea and was believed to be the treasure of mermaids. Sailors carried the stone as a talisman for good luck, protection against drowning, and safe passage. Ancient Greeks and Romans also valued aquamarine for its purported ability to soothe the mind and reduce stress, making it a stone of peace and clarity.
Bloodstone, the alternative March birthstone, is a dark green chalcedony speckled with red iron oxide inclusions, resembling drops of blood. Its lore is deeply rooted in religious and warrior traditions. Early Christians believed it was formed from the blood of Christ falling on the green earth at the crucifixion, giving it the name "martyr's stone." It was used in the Middle Ages to carve scenes of the crucifixion. For ancient warriors, bloodstone was a symbol of courage and was worn or carried into battle to staunch bleeding and ensure victory. Its association with Mars, the Roman god of war, further cemented its reputation as a protective and empowering stone.
Geological Formation and Sources
Amethyst: A Variety of Quartz
Amethyst is a variety of quartz, a mineral composed of silicon dioxide (SiO₂). Its distinctive purple color is due to the presence of iron impurities and natural irradiation during its formation. Amethyst is found in geodes and volcanic rocks, often in large crystalline formations. Major sources include Brazil, which is the world's leading producer of amethyst, as well as Uruguay, Bolivia, and parts of Africa (notably Zambia and Namibia). The quality and color intensity of amethyst can vary significantly based on its geographic origin. For instance, Uruguayan amethyst is often prized for its deep, rich purple hue, while Brazilian amethyst may be lighter in color.
Aquamarine: A Beryl Variety
Aquamarine is a member of the beryl family, which also includes emerald and morganite. Its chemical formula is Be₃Al₂(SiO₃)₆, and its blue color is attributed to trace amounts of iron within the crystal structure. Aquamarine forms in pegmatites and granite veins, often in large, well-formed crystals suitable for gem cutting. The most significant deposits are found in Brazil, particularly in the state of Minas Gerais. Other notable sources include Pakistan, Madagascar, and Nigeria. Brazilian aquamarine is renowned for its exceptional clarity and vibrant blue color, making it a favorite among gemologists and jewelers.
Bloodstone: A Form of Chalcedony
Bloodstone is a variety of chalcedony, a microcrystalline form of quartz. It is composed of silicon dioxide (SiO₂) with iron oxide inclusions that create its characteristic red spots. Bloodstone is typically found in volcanic or metamorphic rocks. Key sources include India, Brazil, Australia, and the United States (notably in California and Oregon). The stone is often cut into cabochons to highlight its unique pattern, as faceting can obscure the blood-like inclusions.
Gemological Properties
The gemological properties of amethyst, aquamarine, and bloodstone differ significantly, reflecting their distinct mineral compositions and structures. These properties influence their durability, appearance, and suitability for various types of jewelry.

| Amethyst | Quartz (Silica) | SiO₂ | 7 | 1.544–1.553 | 2.65 | Heat treatment to lighten or remove color zones; irradiation to enhance purple |
| Aquamarine | Beryl | Be₃Al₂(SiO₃)₆ | 7.5–8 | 1.577–1.583 | 2.68–2.70 | Heat treatment to improve blue color; irradiation to remove yellow/green tones |
| Bloodstone | Chalcedony (Quartz) | SiO₂ | 6.5–7 | 1.535–1.539 | 2.58–2.64 | Generally not treated; polishing to enhance luster |
Amethyst
Amethyst has a hardness of 7 on the Mohs scale, making it durable enough for everyday wear in rings, earrings, and pendants. It has a vitreous luster and is often found with excellent clarity, though some specimens may contain inclusions like needles or zoning. Amethyst is sensitive to heat and prolonged exposure to strong light, which can cause fading. It is typically cut into faceted shapes such as rounds, ovals, and emerald cuts to maximize its brilliance.
Aquamarine
Aquamarine is harder than amethyst, with a Mohs hardness of 7.5 to 8, making it one of the more durable gemstones for jewelry. It exhibits a vitreous luster and is prized for its exceptional clarity, often being nearly inclusion-free. Aquamarine is also heat-treated to enhance its blue color, a common and stable practice in the gem trade. The stone is typically cut into faceted shapes to highlight its clarity and color, with popular cuts including emerald, oval, and pear shapes.
Bloodstone
Bloodstone has a Mohs hardness of 6.5 to 7, slightly lower than aquamarine but still suitable for jewelry, particularly in pieces less prone to impact, such as pendants and brooches. It is usually cut as a cabochon to showcase its distinctive red inclusions against the green background. Bloodstone is rarely treated, as its value lies in its natural pattern. It has a waxy to vitreous luster and can contain minor inclusions.
Symbolism and Metaphysical Beliefs
Amethyst: Spiritual Clarity and Protection
Amethyst is deeply intertwined with spiritual and metaphysical beliefs. It is associated with the crown chakra, which governs intuition, higher awareness, and spiritual connection.
