May is a month rich in symbolism and celebration, often associated with rebirth, growth, and renewal. As such, the birthstones linked to this month carry meanings that reflect these themes. The traditional May birthstone is the emerald, a gemstone of deep green color and long-standing significance in both cultural and gemological contexts. However, over the centuries, alternative birthstones have also emerged, including agate and chrysoprase, each with its own unique history and symbolism. This article explores the traditional and alternative May birthstones in detail, covering their geological properties, historical and cultural significance, and their roles in modern jewelry and metaphysical practices.
Introduction
For those born in May, the emerald is the most well-known and widely accepted birthstone. Its vibrant green hue and historical associations with love, wisdom, and fertility make it a fitting symbol for the springtime month. However, the concept of birthstones is not fixed and has evolved over time. Alternative May birthstones, such as agate and chrysoprase, have gained popularity due to their symbolic resonance with the characteristics of May-born individuals. These stones are often considered to enhance creativity, emotional balance, and spiritual clarity. This article will examine the properties, history, and cultural significance of these gemstones, offering a comprehensive overview of the May birthstone tradition and its evolution.
History and Lore
The tradition of birthstones dates back thousands of years, with early references found in biblical texts and ancient civilizations. In the Bible, the Breastplate of Aaron (Exodus 28:15–30) lists twelve gemstones, each associated with a tribe of Israel, though the exact identification of these stones remains debated. By the 1st century AD, the Roman scholar Pliny the Elder referenced 12 gems in his Naturalis Historia, which were later linked to the zodiac signs. These early systems formed the foundation for the modern birthstone lists, which were standardized in the 20th century by organizations such as the National Association of Jewelers (now Jewelers of America).
The May birthstone has had multiple variations over time. The traditional May birthstone is the emerald, a gemstone that has been treasured for millennia. In ancient Greece and Rome, emeralds were believed to possess healing properties and were associated with the goddess Venus, symbolizing love and beauty. Emeralds were also used in royal courts, particularly in Mughal India and by Spanish conquistadors who brought large emeralds from South America.
Agate, on the other hand, has a more recent emergence as an alternative May birthstone. It is sometimes linked with the zodiac sign Gemini, which spans May 21 to June 20. Agate is a type of chalcedony, a microcrystalline quartz known for its wide range of colors and patterns. The alternative May birthstone chrysoprase, a variety of chalcedony with a green color, is also associated with May and is known as the "Stone of Joy."
The inclusion of alternative May birthstones reflects the evolving nature of the birthstone tradition. While emerald has remained the dominant choice, agate and chrysoprase offer additional symbolic meanings and gemological properties that resonate with the characteristics of May-born individuals.
Geological Formation and Sources
Emerald
Emerald is a variety of beryl, a mineral composed of beryllium aluminum silicate. Its signature green color is due to the presence of trace amounts of chromium or vanadium. Emeralds are typically found in metamorphic rocks, particularly in areas where hydrothermal fluids have interacted with the host rock. These conditions are ideal for the formation of emeralds, which require specific geological settings to develop their color and clarity.
The most famous sources of emeralds are in South America, particularly in Colombia, which is widely regarded as the premier producer of fine emeralds. Colombian emeralds are known for their vivid green color and high quality. Other notable sources include Brazil,赞比亚 (Zambia), and Afghanistan. The mining of emeralds is often a labor-intensive process, as the gemstone is fragile and prone to cracking during extraction.
Emeralds are typically cut in a step or emerald cut to maximize their clarity and brilliance. Due to their inclusions, emeralds are often referred to as "garden" stones, as the visible inclusions resemble the appearance of a garden. These inclusions are not considered flaws but rather part of the gemstone's natural character.
Agate
Agate is a type of chalcedony, which is a member of the quartz family. It forms when silica-rich water percolates through rock cavities and deposits layers of chalcedony over time. The result is a gemstone with distinct bands or patterns, often in a range of colors. Agate is found in many parts of the world, including Brazil, India, Africa, and the United States.
The most common varieties of agate used as birthstones include the blue lace agate and the moss agate. Blue lace agate is known for its delicate blue and white patterns, while moss agate features green inclusions that resemble plant life. Both types are highly valued for their aesthetic appeal and metaphysical properties.
Agate is a relatively hard gemstone, ranking at 6.5–7 on the Mohs scale, making it durable and suitable for everyday wear. It is often used in a variety of jewelry forms, including rings, bracelets, and pendants. Agate is also popular in spiritual and metaphysical practices due to its grounding and calming properties.
Chrysoprase
Chrysoprase is another variety of chalcedony, distinguished by its vibrant green color, which is caused by the presence of nickel. Like other chalcedony varieties, chrysoprase forms when silica-rich water deposits layers of mineral over time. It is often found in serpentinite rock, a type of metamorphic rock that is common in areas with volcanic activity.
The primary source of chrysoprase is Australia, particularly in the state of Queensland. Other sources include Brazil, Russia, and the United States. Chrysoprase is known for its smooth, waxy luster and is often cut in cabochon or domed shapes to enhance its color and texture.
Chrysoprase is a popular alternative May birthstone due to its association with joy and positivity. It is believed to promote emotional healing and encourage a sense of optimism. The gemstone is also valued for its affordability and versatility, making it a popular choice for jewelry and decorative objects.

Emerald
Emerald is one of the most valuable gemstones in the world, largely due to its rarity and the difficulty in mining and cutting the stone. Its hardness on the Mohs scale is 7.5–8, which makes it relatively durable but still susceptible to damage if not handled carefully. The chemical formula of emerald is Be₃Al₂(SiO₃)₆, and it has a refractive index of 1.57–1.58, giving it a brilliant sparkle. The specific gravity of emeralds ranges from 2.67 to 2.80, making them slightly heavier than other gemstones of similar size.
Emeralds are often treated with oils or resins to enhance their color and clarity. This is a common practice in the gem trade, as untreated emeralds are extremely rare. However, it is important for consumers to be aware of these treatments, as they can affect the gemstone's value and durability.
Agate
Agate is a more affordable and accessible gemstone compared to emerald, making it a popular choice for jewelry and decorative items. Its hardness on the Mohs scale is 6.5–7, which means it is durable and suitable for everyday wear. The chemical formula of agate is SiO₂, with varying amounts of water and other impurities that give it its distinct colors and patterns.
Agate has a refractive index of 1.48–1.53 and a specific gravity of 2.58–2.64. These properties contribute to its smooth and waxy luster, which is highly valued in gemstone aesthetics. Agate is also known for its piezoelectric properties, which means it can generate a small electric charge when subjected to pressure. This property is not typically used in jewelry but is of interest in scientific and technological applications.
Chrysoprase
Chrysoprase is a relatively soft gemstone compared to emerald, with a hardness of 6.5–7 on the Mohs scale. Its chemical formula is SiO₂ with trace amounts of nickel, which gives it its green color. The refractive index of chrysoprase ranges from 1.50 to 1.60, and its specific gravity is 2.30–2.60. These properties make chrysoprase a versatile gemstone that can be used in a variety of jewelry designs.
Chrysoprase is often cut in cabochon form to showcase its smooth, waxy luster and vibrant green color. It is also popular in carvings and decorative objects due to its ease of workability. Unlike emeralds, chrysoprase is not commonly treated, as it naturally has a beautiful color and luster. This makes it a desirable choice for those who prefer untreated gemstones.
