History and Lore
The tradition of birthstones is ancient, with roots in biblical texts and historical gemology. However, the specific association of gemstones with zodiac signs, as opposed to calendar months, is a more modern interpretation that blends astrology with mineral lore. For Aquarius, the gemstones are chosen to complement the sign's elemental association with air and its ruling planet, Uranus, which is linked to innovation, rebellion, and higher consciousness.
Amethyst, as the February birthstone, has a long history of use. Historically, it was considered a stone of royalty and was used by the ancient Greeks and Romans to ward off intoxication and maintain a clear mind—a property that aligns with the Aquarian pursuit of clarity and intellectual focus. The stone's purple hue, ranging from light lavender to deep violet, was also associated with spirituality and piety in various cultures. In the context of Aquarius, amethyst is believed to enhance the sign's natural intuition and spiritual insight, helping to calm the sometimes nervous or abrupt energy associated with Uranus.
Aquamarine, derived from the Latin words for "sea water," has been cherished since antiquity. Sailors and travelers carried it as a talisman for protection and good luck. Its connection to water and the sea resonates with the humanitarian and compassionate nature of Aquarius, symbolizing the flow of emotions and the adaptability of the sign. The stone's lore emphasizes courage and clarity, making it a fitting gem for the progressive and forward-thinking Aquarian.
Blue Sapphire has been a stone of wisdom and royalty for centuries. In ancient Persia, it was believed to be a celestial stone that reflected the sky and held the power of divine favor. Its deep blue color is associated with mental clarity and truth, qualities that are highly valued by the intellectually driven Aquarius. The stone's historical use in royal jewelry underscores its symbolism of authority and insight, traits that many Aquarians embody in their quest for knowledge and social reform.
Turquoise, one of the oldest known gemstones, has been used by civilizations across the globe, from ancient Egypt to the Native American tribes of the Southwest. It is traditionally a stone of protection, healing, and communication. For Aquarius, turquoise is thought to enhance self-expression and personal growth, supporting the sign's desire to share innovative ideas and connect with others on a deeper level.
Garnet, while typically red, comes in a variety of colors, including blue, which is specifically mentioned in the sources as an alternative for Aquarius. Historically, garnet has been a symbol of passion, energy, and vitality. For the typically detached and humanitarian Aquarius, garnet is believed to provide a boost of motivation and drive, helping to ground their visionary ideas into tangible action.
Geological Formation and Sources
The gemstones associated with Aquarius are sourced from various geological environments around the world, each contributing to their unique properties and availability.
Amethyst is a variety of quartz, with its purple color resulting from trace amounts of iron and natural irradiation. Major sources include Brazil, Uruguay, and Zambia. Brazilian amethyst is often found in large geodes and can produce deep, saturated colors, while Uruguayan amethyst is known for its intense dark purple with flashes of red. The geological conditions for amethyst formation typically involve hydrothermal activity in volcanic or metamorphic rocks.
Aquamarine is a variety of beryl, the same mineral family as emerald and morganite. Its blue color comes from trace amounts of iron. Significant deposits are found in Brazil, Nigeria, Madagascar, and Pakistan. The largest and most valuable aquamarine crystals often come from Brazil, particularly from the Minas Gerais region. Aquamarine forms in pegmatites, which are coarse-grained igneous rocks that allow for the growth of large, well-formed crystals.
Blue Sapphire is a variety of corundum, with its blue color primarily due to trace amounts of titanium and iron. The most prized sapphires come from Kashmir, Sri Lanka, and Myanmar (Burma). Kashmir sapphires are renowned for their velvety blue hue, while Sri Lankan sapphires are known for their clarity and range of blue shades. Sapphires form in metamorphic rocks, such as marble and aluminous gneiss, and are also found in alluvial deposits.
Turquoise is a hydrated phosphate of copper and aluminum. Its blue-to-green color is determined by the amount of copper (blue) and iron (green) present. Major sources include Iran (historically the most prized), the southwestern United States (Arizona, New Mexico), and China. Turquoise forms in arid regions where acidic water percolates through rocks rich in copper and aluminum, depositing the mineral in fractures and voids.
Garnet is a group of silicate minerals that share a similar crystal structure but have different chemical compositions. Blue garnet is extremely rare and is typically a variety of andradite or grossular garnet that displays a color change from blue-green to purple under different lighting conditions. Sources for blue garnet are limited, with notable occurrences in Madagascar and Sri Lanka. Garnets form in metamorphic and igneous rocks, and their varied compositions lead to a wide range of colors and properties.
Blue Topaz is a silicate mineral, with its blue color usually achieved through irradiation and heat treatment of colorless topaz. Natural blue topaz is rare; most commercial blue topaz is treated. Major sources include Brazil, Nigeria, and Sri Lanka. Topaz forms in pegmatites and vapor cavities in igneous rocks.
Blue Lace Agate is a variety of banded chalcedony, a microcrystalline form of quartz. Its delicate blue and white bands are formed by silica deposits in volcanic rock cavities. Sources include Brazil, India, and the United States (Oregon).
Labradorite is a plagioclase feldspar known for its labradorescence—a play of iridescent colors. Its primary source is Labrador, Canada, but it is also found in Madagascar, Finland, and Russia. Labradorite forms in basaltic and other igneous rocks.
Aquamarine (as a birthstone for March) and Amethyst (for February) are the traditional monthly birthstones that fall within the Aquarius period, making them the most widely recognized gemstones for this sign.

Color: The dominant color for Aquarius birthstones is blue, ranging from the pale sky blue of aquamarine and blue lace agate to the deep indigo of sapphire. Amethyst introduces a purple hue, which is also considered complementary. The color in these gems is caused by trace elements: iron in aquamarine and sapphire, copper in turquoise, and various transition metals in garnet. The unique iridescence of labradorite is due to its internal structure, which splits light into its spectral colors.
Clarity: Clarity varies significantly among these gemstones. Aquamarine and blue topaz are typically found with good clarity, often with inclusions that are acceptable in gem-quality material. Sapphires can contain various inclusions, such as silk (rutile needles), which can affect transparency but also contribute to the stone's character. Amethyst may have color zoning or inclusions like mineral needles. Turquoise is often opaque or translucent and is frequently treated or stabilized to improve its appearance and durability. Garnets are generally clean, while labradorite's value is often tied to the quality of its labradorescence rather than absolute clarity.
Cut: These gemstones are cut into a variety of shapes to maximize color, brilliance, and the display of special optical effects. Amethyst, aquamarine, and topaz are often cut into standard brilliant cuts or step cuts. Sapphires are commonly cut into oval, cushion, or emerald cuts. Turquoise is frequently cut into cabochons to showcase its color and matrix. Labradorite is typically cut en cabochon to best display its labradorescence. Garnets are cut in many shapes, with color-change varieties often cut to optimize the color shift.
Carat Weight: All these gemstones are available in a wide range of sizes. Large, fine-quality sapphires and aquamarines are particularly valuable. Amethyst can be found in large sizes at relatively affordable prices. Turquoise is often used in larger pieces for jewelry and carvings. Blue topaz is commonly available in larger sizes due to its affordability and treatment process.
Hardness: On the Mohs scale of hardness, corundum (sapphire) and topaz are among the hardest, with sapphire at 9 and topaz at 8. Aquamarine and amethyst (quartz) are also durable, with hardness of 7.5-8 and 7, respectively. Garnets range from 6.5 to 7.5. Labradorite is slightly softer at 6-6.5. Turquoise is the softest of this group, with a hardness of 5-6, making it more susceptible to scratching and requiring careful handling.
Chemical Stability: Most of these silicate minerals are chemically stable and resistant to common chemicals. However, turquoise is sensitive to acids, heat, and prolonged exposure to lotions, perfumes, and sweat, which can damage its surface. Sapphires and rubies are highly stable, while amethyst can fade with prolonged exposure to strong light or heat.
