The month of March is symbolically rich, marking the transition from winter to spring and the beginning of new cycles of growth and renewal. In the world of gemstones, March is represented by two official birthstones: aquamarine and bloodstone. These two gemstones, though vastly different in appearance and origin, share a long and storied history that spans centuries of cultural, spiritual, and symbolic significance.
This article delves into the world of the March birthstones, exploring their geological properties, historical and mythological associations, and their modern-day relevance in jewelry and gemology. We will examine the scientific formation and characteristics of each gem, their traditional uses and meanings, and the reasons behind their dual designation as March birthstones.
History and Lore
The tradition of birthstones dates back to ancient times, with roots in biblical and early cultural practices. According to one of the earliest known references, the 12 gemstones of the Breastplate of Aaron in the Old Testament were believed to represent the 12 tribes of Israel and were later linked to the 12 months of the year and zodiac signs. This connection formed the foundation of modern birthstone traditions.
For March, bloodstone was originally the sole representative gemstone. This deep green chalcedony, speckled with red spots resembling blood, was revered in ancient times for its protective and healing properties. It was believed to be formed from the blood of Christ, a belief that contributed to its widespread use in medieval Europe for talismans and religious artifacts.
However, the modern era has introduced aquamarine as an official birthstone for March, alongside bloodstone. The inclusion of aquamarine in this list reflects both a refinement in gem identification and a shift in cultural preferences over time. The term "aquamarine" is derived from the Latin aqua marina, meaning "water of the sea," a fitting name for a gemstone that captures the essence of the ocean in its color and clarity.
Aquamarine has been cherished since antiquity, with evidence of its use in jewelry and decorative arts found in ancient Egypt, Greece, and Rome. The Romans believed it to be a protective talisman for sailors, who would carry aquamarine to ward off storms and ensure safe passage across the seas. This belief in the gem’s connection to water and navigation has persisted through the ages, contributing to its enduring appeal.
The dual designation of aquamarine and bloodstone as March birthstones is a reflection of evolving gemological knowledge and cultural practices. In the 15th and 16th centuries, as European jewelers began to market birthstone jewelry, the selection of stones became more refined and standardized. By the 19th century, with the influence of companies like Tiffany & Co., who popularized birthstone jewelry through poetry and marketing, the modern list of birthstones was largely established. Aquamarine, with its vibrant blue color and gemological qualities, rose to prominence as the primary March birthstone, while bloodstone remained as an alternative, preserving its historical roots.
Both stones are now widely accepted as symbols of March, representing not only the month itself but also the zodiac signs of Pisces and Aries. Aquamarine is associated with Pisces, the water sign known for its intuition and sensitivity, while bloodstone is linked to Aries, the fiery and determined first sign of the zodiac.
Geological Formation and Sources
Understanding the geological origins and sources of aquamarine and bloodstone provides insight into their rarity, beauty, and value in the gemstone world.
Aquamarine
Aquamarine is a variety of beryl, a mineral that forms in igneous rock environments, particularly in granite pegmatites. Beryl crystals grow slowly over long periods, often resulting in large and well-formed specimens. The blue color of aquamarine is due to the presence of iron impurities within the crystal structure. The intensity of the blue can vary, with lighter shades being more common than deeper, saturated blues.
The largest aquamarine crystals in the world have been found in Brazil, where the gem is most commonly mined. Brazil is responsible for the majority of the world’s aquamarine supply, with major deposits in the states of Minas Gerais and Bahia. Other notable sources include:
- Madagascar
- Kenya
- Nigeria
- Mozambique
- Angola
- Russia
- Zambia
- Pakistan
- Tanzania
- Colorado, USA
Aquamarine is often found in massive deposits and can be cut into large faceted stones or used for carving. Its clarity and transparency make it ideal for jewelry, and it is frequently set in rings, pendants, and earrings. The gem is also known for its durability, with a Mohs hardness of 7.5 to 8, making it resistant to scratches and suitable for everyday wear.
Bloodstone
Bloodstone, also known as heliotrope, is a type of chalcedony, a microcrystalline variety of quartz. It is characterized by a dark green background with small red spots that resemble drops of blood. These red inclusions are typically due to iron oxide (hematite) embedded within the stone.
The formation of bloodstone occurs in sedimentary rock environments, where chalcedony is deposited and later impregnated with iron oxide. The process can take millions of years, resulting in the distinctive appearance of the gem.
Historically, bloodstone was mined in India, particularly in the state of Jabalpur, which is still a significant source today. Other sources include:
- Russia
- Germany
- Australia
- United States
Bloodstone is usually cut into cabochons rather than being faceted, as its opaque nature and inclusions make it unsuitable for faceting. It is commonly used in rings, pendants, and beads, and its deep green color makes it a striking contrast to gold or silver settings.
With a Mohs hardness of 6.5 to 7, bloodstone is relatively durable but requires more care than aquamarine due to its porous nature and susceptibility to acid and heat.
Gemological Properties
To fully appreciate the beauty and value of aquamarine and bloodstone, it is essential to understand their gemological properties, including color, clarity, hardness, and chemical composition.
