March, the first month of spring, is symbolized by two distinct yet equally compelling birthstones: aquamarine and bloodstone. While aquamarine, with its serene blue hues, evokes the calm of the sea and has become the more widely recognized of the two in modern times, bloodstone, with its deep green and crimson speckles, carries a rich historical tradition as the original March gemstone. Together, these stones reflect the transition from winter to spring, embodying themes of renewal, protection, and spiritual strength.
This article explores the origins, properties, symbolism, and care of both March birthstones, drawing on centuries of lore and scientific understanding to present a comprehensive view of these remarkable gems. Whether you are a gemstone enthusiast, a jewelry buyer, or a student of gemology, the story of aquamarine and bloodstone offers a fascinating window into the interplay between nature, culture, and human history.
History and Lore
The tradition of associating gemstones with the months of the year can be traced back to ancient times, with roots in biblical and classical sources. By the 1st century AD, the practice of assigning gemstones to each month—and by extension, to zodiac signs—began to take shape. Early records, such as the High Priest’s breastplate described in the Book of Exodus, list 12 stones that may have influenced later birthstone traditions.
In the case of March, bloodstone was originally the sole representative in many ancient and medieval birthstone lists. This opaque, deep green gemstone, flecked with red iron oxide, was believed to possess protective and healing properties. Bloodstone was revered in various cultures for its ability to strengthen the body and purify the mind. The red spots in the stone were thought to symbolize the blood of Christ, and in medieval times, bloodstone was often used in Christian amulets.
Aquamarine, by contrast, did not emerge as a birthstone until later in history. The name “aquamarine” comes from the Latin words aqua, meaning “water,” and mare, meaning “sea,” a reference to its blue-green color. This gemstone was historically known as “the sailor’s gem,” and ancient Greeks and Romans believed that carrying aquamarine would protect them from the dangers of the sea. It was also thought to bring happiness in marriage and to offer protection during battles and legal disputes.
The inclusion of aquamarine as a March birthstone is a relatively modern development. By the 1800s, standardized birthstone lists began to emerge, and aquamarine was added as an alternative to bloodstone. In 1912, the National Association of Jewellers (now known as the Jewellers of America) published a list that officially recognized both aquamarine and bloodstone as March birthstones. This dual designation reflects the evolving nature of birthstone traditions, which are shaped by cultural shifts, gemological discoveries, and commercial influences.
Today, aquamarine is often considered the primary birthstone for March, particularly in the United States and the United Kingdom. However, bloodstone remains an important and respected alternative, preserving the older traditions that have endured for centuries.
Geological Formation and Sources
Both aquamarine and bloodstone are formed through natural geological processes, but they originate from different mineral families and environments.
Aquamarine
Aquamarine is a member of the beryl family, a group of beryllium aluminum silicate minerals. In its pure form, beryl is colorless, but trace elements can cause it to take on a range of colors. Aquamarine, in particular, owes its blue-green hue to the presence of iron (Fe). The stone is typically found in granitic pegmatites and metamorphic rocks, where it forms under high-temperature and high-pressure conditions.
The most significant sources of aquamarine today include:
- Brazil, especially in the states of Minas Gerais and Bahia, which are among the world’s leading producers of high-quality aquamarine.
- Nigeria, where aquamarine is also mined in large quantities.
- Madagascar, a growing source of aquamarine, particularly for lighter-colored varieties.
- Zambia, which produces aquamarine with a more intense blue hue.
- Russia and Afghanistan, which were historically important sources but are now less prominent.
Aquamarine is often faceted to highlight its clarity and color. High-quality specimens are typically free from inclusions and have a glassy, transparent appearance. Its Mohs hardness of 7.5 to 8 makes it durable enough for use in jewelry, though it should still be handled with care to avoid scratches or chipping.
Bloodstone
Bloodstone, also known as heliotrope, is a type of jasp—a translucent to opaque quartz-based mineral. It is composed primarily of chert or chalcedony, with flecks of hematite or iron oxide that give it its characteristic red spots. The red inclusions are believed to form when iron-rich fluids seep into the quartz and oxidize over time.
Bloodstone is most commonly found in:
- India, which is the largest modern source of bloodstone.
- Brazil, where it is also mined in significant quantities.
- Germany and the Czech Republic, which were historically important sources during the Renaissance and Baroque periods.
Bloodstone is typically cut into cabochons rather than being faceted, as its opaque nature and the presence of inclusions make faceting less effective. It has a Mohs hardness of 6.5 to 7, which is slightly lower than aquamarine, making it more susceptible to scratches and damage.
Gemological Properties
The gemological properties of aquamarine and bloodstone reflect their distinct mineral compositions and origins. Below is a detailed comparison of their key characteristics:
| Property | Aquamarine | Bloodstone |
|---|---|---|
| Mineral Class | Beryl (Beryllium aluminum silicate) | Chalcedony (Silica-based mineral) |
| Chemical Formula | Be₃Al₂(SiO₃)₆ | SiO₂ (Silicon dioxide) with iron oxide inclusions |
| Color | Blue to blue-green, with a range from light to deep shades | Deep green with red spots (iron oxide) |
| Transparency | Transparent to translucent | Opaque |
| Luster | Vitreous (glassy) | Waxy to dull |
| Hardness (Mohs) | 7.5 to 8 | 6.5 to 7 |
| Cleavage | None or poor | None or poor |
| Luminescence | Fluorescent in some cases | None |
| Common Cuts | Faceted (brilliant, emerald, etc.) | Cabochon |
| Origin | Brazil, Nigeria, Madagascar, Zambia | India, Brazil, Germany, Czech Republic |
Aquamarine’s high clarity and transparency make it ideal for faceting, while bloodstone’s opacity and inclusions make it better suited for cabochon cuts. Both gemstones are relatively durable due to their hardness, but they require careful handling to avoid scratches and damage.
Aquamarine is also known for a unique optical property called pleochroism, which means it can display different colors when viewed from different angles. This effect is most noticeable in certain lighting conditions and is one of the reasons aquamarine is so captivating to gemstone collectors.
Bloodstone, while lacking the same optical effects as aquamarine, is prized for its rich color and historical significance. Its deep green and red spots give it a dramatic, eye-catching appearance that has been valued in jewelry and amulets for centuries.
