March is a month of transition, bridging the last days of winter with the first stirrings of spring. This duality is reflected in its birthstones—Aquamarine and Bloodstone—each carrying a distinct color and meaning that captures the essence of the season. The primary birthstone, Aquamarine, is known for its tranquil blue hues, reminiscent of the sea and sky, while Bloodstone, its traditional alternative, brings an earthy, bold presence with its deep green and red flecks. Together, these gemstones offer a rich visual and symbolic palette, making March one of the most interesting and diverse months in the birthstone calendar.
This article explores the color characteristics of March’s birthstones in detail, drawing from the latest gemological insights and historical lore. From their geological formation and global sources to their spiritual significance and practical use in jewelry, we examine how these stones have come to represent the essence of March. The discussion will include their symbolic meanings, how to care for them, and their role in both modern and traditional jewelry design.
History and Lore
The practice of associating gemstones with specific months of the year dates back centuries, with roots in ancient civilizations that believed in the mystical and protective powers of stones. The March birthstones, Aquamarine and Bloodstone, have been part of this tradition for a long time, though their roles have evolved over the centuries.
Aquamarine, with its calming blue tones, is believed to have been known to ancient civilizations as early as the Greeks and Romans. The name "Aquamarine" is derived from the Latin phrase aqua marina, meaning "water of the sea," a name that perfectly encapsulates its color and the legends associated with it. Sailors often carried Aquamarine as a talisman to protect them from the perils of the sea, believing it brought them luck and safety. This connection to the sea and protection has carried through to modern times, where Aquamarine is still seen as a stone of calm and courage.
Bloodstone, the alternative birthstone for March, has a more ancient and martial history. It has been used for thousands of years and is one of the oldest known gemstones in human history. Bloodstone is a type of chalcedony, a cryptocrystalline form of quartz, and its deep green color is often flecked with red spots that resemble drops of blood—hence its name. In ancient times, Bloodstone was believed to promote courage and strength, especially in battle. Warriors would carry it into combat, and it was also used in early medicine for its supposed detoxifying properties. Some historical texts suggest that Bloodstone was even considered to have life-giving properties, which may have contributed to its name.
The transition of Aquamarine from a sailor’s charm to a modern birthstone is a more recent development. While Bloodstone has long been recognized as a March birthstone, Aquamarine was added to the list in the 20th century. This addition was likely influenced by the popularity of beryl gemstones, including emerald, and the growing interest in birthstones as symbols of personal identity and meaning. Today, both Aquamarine and Bloodstone are considered official March birthstones, with Aquamarine serving as the primary choice and Bloodstone as the traditional alternative.
Geological Formation and Sources
Understanding the color of March birthstones requires an understanding of the geological processes that form them. Each gemstone has its own unique formation history, mineral composition, and geographical sources, all of which influence its color and availability.
Aquamarine
Aquamarine is a member of the beryl family, a group of minerals that includes emerald and morganite. Beryl is a silicate mineral with the chemical formula Be₃Al₂(SiO₃)₆. The blue color of Aquamarine is due to the presence of trace amounts of iron (Fe²⁺), which gives it its characteristic hue. The intensity of the blue can vary depending on the concentration of iron and other trace elements.
Aquamarine typically forms in granitic pegmatites, which are coarse-grained igneous rocks that form as magma cools. These environments allow for the slow crystallization of minerals, including beryl, resulting in large, well-formed crystals. The most significant sources of Aquamarine are found in Brazil, particularly in the states of Minas Gerais and Bahia. Other notable sources include Nigeria, Madagascar, Pakistan, and India.
Aquamarine is relatively hard, with a Mohs hardness of 7.5 to 8, making it durable enough for use in jewelry. Its clarity is often excellent, and the most valuable specimens are those with a deep, intense blue color and minimal inclusions. The availability of Aquamarine has increased over the years due to advancements in mining and cutting techniques, making it more accessible to the general public.
Bloodstone
Bloodstone, also known as Heliotrope, is a type of chalcedony, a cryptocrystalline form of quartz. Chalcedony is composed of microcrystalline silica and is typically translucent to opaque. The green color of Bloodstone is due to the presence of iron in the chalcedony matrix, while the red flecks are caused by inclusions of iron oxide, specifically hematite. These red spots give Bloodstone its distinctive appearance and are the reason for its name.
Bloodstone forms in sedimentary rocks and volcanic deposits, often in association with other chalcedony and quartz varieties. The most significant sources of Bloodstone include India, Brazil, Australia, and the United States. Indian Bloodstone, in particular, is highly prized for its deep green color and vibrant red flecks.
Bloodstone has a slightly lower hardness than Aquamarine, with a Mohs rating of 6.5 to 7. This means that it is more susceptible to scratches and damage than Aquamarine, so it requires more careful handling and cleaning. Despite its lower hardness, Bloodstone is still a popular gemstone, especially in cabochon form, which showcases its unique color pattern and minimizes the risk of damage.
Gemological Properties
The color and appearance of a gemstone are not just aesthetic qualities—they are also important indicators of its gemological properties. These properties include hardness, refractive index, chemical composition, and optical characteristics, all of which influence how a gemstone is used and valued.
Aquamarine
Aquamarine has a chemical composition of Be₃Al₂(SiO₃)₆, as mentioned earlier. It has a refractive index of 1.57 to 1.58, which gives it a vitreous or glassy luster. This refractive index is relatively low compared to other gemstones, but it is still sufficient to produce a clear, bright appearance.
The hardness of Aquamarine (7.5 to 8 on the Mohs scale) makes it suitable for a wide range of jewelry applications, including rings, earrings, and pendants. Its toughness is also relatively good, although it can be affected by sudden temperature changes or impact. Because of its durability and clarity, Aquamarine is often cut into brilliant or emerald cuts to enhance its color and sparkle.
The most desirable Aquamarine stones have a deep, even blue color with minimal greenish undertones. Stones with too much green are often referred to as "green beryl" and are less valuable than true Aquamarine. The intensity of the color can also affect the price, with the most vivid and transparent stones commanding the highest prices.
Bloodstone
Bloodstone, being a chalcedony, has a chemical composition of SiO₂ (silicon dioxide), with trace amounts of iron oxide. Its refractive index is between 1.48 and 1.53, which is lower than that of Aquamarine. This gives Bloodstone a more subdued luster, and it is often cut into cabochons rather than faceted cuts to emphasize its color pattern.
The hardness of Bloodstone (6.5 to 7 on the Mohs scale) is lower than that of Aquamarine, making it more prone to scratches and wear. This means that Bloodstone is best suited for jewelry that is worn less frequently, such as pendants or brooches. It is also important to avoid exposing Bloodstone to harsh chemicals or extreme temperatures, as this can cause discoloration or damage.
The most valuable Bloodstone stones are those with a rich green color and well-defined red flecks. The size and distribution of the red spots can vary, and this can affect the stone’s appearance and value. Stones with too many red flecks may appear mottled or unattractive, while those with too few may lack the characteristic "blood-like" appearance that gives the stone its name.
Symbolism and Metaphysical Beliefs
The colors of March birthstones are not only visually striking but also carry deep symbolic and metaphysical meanings. These meanings have been passed down through generations and continue to influence how people perceive and use these gemstones today.
