History and Lore
The Emergence of May’s Birthstones
The tradition of assigning gemstones to specific months has roots in ancient civilizations. While the exact origins of May’s birthstone tradition are unclear, there are references in both biblical and classical sources that provide insight into how these gemstones came to be associated with the month.
According to some interpretations, the Hebrew tradition linked agate with May, while the Arabic tradition favored emerald. By the 19th century, the emerald had gained widespread recognition as the primary May birthstone. In 1870, Tiffany & Co. published a pamphlet titled “Gregorian Birthstone Poems,” which helped formalize the modern birthstone list. The poem for May read:
“Who first beholds the light of day
In spring’s sweet, flower month of May
And wears an Emerald all her life
Shall be a loved and a loved and a loving wife.”
In 1912, the National Association of Jewellers (now known as Jewellers of America) officially listed emerald as the May birthstone, cementing its place in modern tradition.
The month of May itself has a rich etymology and cultural history. In ancient times, it was referred to as Maius, possibly named after the Roman goddess Maia, associated with growth and fertility. The Romans also celebrated the festival of Floralia in May, a celebration of the goddess Flora, the personification of flowers and spring.
The May birthstone tradition has evolved over time, with alternative gemstones such as chrysoprase and sapphire also being recognized in some cultural and mystical traditions. Chrysoprase, a variety of chalcedony, is known as the “Stone of Joy” and is sometimes listed as an alternative May birthstone. In Tibetan astrology, sapphire is considered the May birthstone, reflecting the diversity of beliefs surrounding these gems.
Emerald in Ancient and Royal History
Emeralds have long been revered by royalty and the elite. Ancient Egyptian pharaohs prized emeralds for their beauty and believed in their protective powers. Cleopatra, one of history’s most iconic figures, was particularly fond of emeralds and incorporated them into her royal adornments.
In South America, the Inca and Spanish empires also held emeralds in high esteem. The legendary Crown of the Andes, a colonial-era piece of jewelry, featured the Atahualpa emerald, a gemstone taken from the last Inca emperor by Spanish conquistador Francisco Pizarro. Emeralds recovered from the sunken Spanish galleon Nuestra Señora de Atocha are among the many treasures that highlight the gem’s historical and economic significance.
Emeralds were also valued for their supposed medicinal properties. In medieval times, it was believed that emeralds could cure diseases such as cholera and malaria. Today, emeralds continue to be associated with youth, intelligence, and good fortune, making them a fitting symbol for the month of May.
Geological Formation and Sources
The Formation of Emerald
Emerald is a variety of the mineral beryl, with its vivid green color derived from trace amounts of chromium or vanadium. It forms in metamorphic rocks under high-pressure and high-temperature conditions. The gem is typically found in hydrothermal deposits, where mineral-rich fluids interact with surrounding rock to form crystals.
The most famous emerald deposits are located in Colombia, where the gem has been mined for centuries. The Muzo and Chivor mines in Colombia are particularly renowned for producing high-quality emeralds. Other notable sources include Brazil, Zambia, Afghanistan, and Egypt. Each region produces emeralds with unique color variations and inclusions, influenced by the geological conditions in which they formed.
Emeralds are often found with inclusions, which are natural imperfections within the stone. These inclusions are not considered flaws but rather evidence of the gem’s natural formation. In fact, the presence of certain inclusions can be used to determine the origin of an emerald, a technique employed by gemologists.
The Formation of Agate
Agate is a microcrystalline variety of quartz, formed through the slow deposition of silica-rich solutions in cavities within volcanic and metamorphic rocks. Over time, these solutions cool and harden, forming bands of color that give agate its distinctive patterns.
Agate is found in many parts of the world, including Brazil, Uruguay, India, and the United States. Different types of agate, such as moss agate and carnelian, are distinguished by their color and banding. Agate is generally more affordable than emerald and is known for its durability and versatility in jewelry design.
Gemological Properties
Emerald’s Scientific Characteristics
Emeralds are known for their rich green color, which is caused by the presence of chromium or vanadium. The gem has a hardness of 7.5 to 8 on the Mohs scale, making it relatively durable but still requiring care to avoid scratches. Its refractive index ranges from 1.577 to 1.583, and it has a specific gravity of 2.67 to 2.78.
Emeralds are typically cut in a rectangular or emerald shape to highlight their clarity and color. The gem can vary in transparency, with the most valuable stones being those with a deep green hue and minimal inclusions. However, as mentioned earlier, inclusions are common in emeralds and are often accepted as part of the gem’s character.
Agate’s Scientific Characteristics
Agate is a form of chalcedony, which is a microcrystalline quartz. It has a hardness of 6.5 to 7 on the Mohs scale, making it more durable than emerald. Agate is often translucent to opaque and is known for its unique banding patterns, which form during its slow crystallization process.
Agate is available in a wide range of colors, including white, gray, brown, and green. Chrysoprase, a green variety of agate, is sometimes used as an alternative May birthstone. Agate is typically cut into cabochons or beads for use in jewelry and decorative objects.
Symbolism and Metaphysical Beliefs
Emerald: A Symbol of Rebirth and Vitality
Emeralds have long been associated with themes of renewal, growth, and vitality. In ancient times, it was believed that emeralds could enhance intelligence, foresight, and youthfulness. The gem was also thought to have healing properties, particularly for diseases of the digestive system.
In modern times, emeralds continue to be linked with love, harmony, and abundance. They are often given as gifts for the 20th and 35th wedding anniversaries, symbolizing enduring love and commitment. Emeralds are also believed to bring good fortune to those who wear them, making them a popular choice for those born in May.
Agate: A Stone of Balance and Protection
Agate is known for its grounding and stabilizing properties. In metaphysical traditions, it is believed to promote emotional balance, enhance courage, and provide protection from negative energies. Agate is also associated with the heart chakra, making it a popular stone for those seeking emotional healing and inner peace.
In some cultures, agate is used to ward off illness and misfortune. It is also believed to enhance communication and foster strong relationships. The variety of colors and patterns in agate makes it a versatile gemstone, with each type carrying its own unique meaning.
Care and Cleaning
Caring for Emeralds
Emeralds require careful handling due to their relative softness and susceptibility to fractures. The gem should be protected from sharp impacts and extreme temperatures. It is also important to avoid exposure to harsh chemicals, which can damage the stone’s surface.
To clean an emerald, it is best to use warm, soapy water and a soft brush. Ultrasonic and steam cleaners are generally not recommended, as they can cause damage to the gem. Emeralds should be stored separately from harder gemstones to prevent scratches.
Caring for Agate
Agate is more durable than emerald and can be cleaned using similar methods. A mild soap and water solution is effective for removing dirt and grime. Agate can also be cleaned with an ultrasonic cleaner, though it is always advisable to check with a professional jeweler before using such methods.
Agate should be stored in a dry, cool place to prevent any changes in color or structure. While agate is generally stable, prolonged exposure to direct sunlight can cause fading in some varieties.
Modern Relevance and Styling
Emerald in Contemporary Jewelry
Emeralds remain a popular choice in modern jewelry, particularly for engagement rings, pendants, and earrings. Their vibrant green color adds a touch of elegance and sophistication to any design. High-quality emeralds are often set in platinum or white gold to enhance their brilliance.
Emeralds are also featured in vintage and antique jewelry collections, where their rich history and craftsmanship add to their allure. Custom-designed pieces that incorporate emeralds allow for creative expression and personalization, making them a meaningful and timeless choice.
Agate in Contemporary Jewelry
Agate is a versatile gemstone that can be styled in a variety of ways. Its affordability and durability make it a popular choice for everyday wear. Agate is often used in beads, pendants, and bracelets, where its natural patterns and colors can be showcased.
Chrysoprase, a green variety of agate, is particularly popular for May-born individuals. Its bright green color symbolizes joy and vitality, making it a fitting alternative to emerald. Agate is also used in combination with other gemstones to create unique and colorful designs.
