History and Lore of the May 16th Birthstone
The emerald has long been revered for its vivid color and symbolic power. Its deep green hue has inspired admiration and reverence across cultures and eras, often linked to themes of life, fertility, and renewal. The history of emerald as a birthstone for May is intertwined with ancient traditions and evolving cultural practices.
The association of emerald with May dates back to ancient times. The month of May was known as Maius in Latin, possibly named after the Roman goddess Maia, a deity of growth and nurturing. Another theory suggests it was named for the Greek goddess Maia, who was also associated with motherhood and the nurturing of life. These early connections to growth and fertility laid the foundation for emerald’s role as a symbol of rebirth and renewal.
In ancient Rome, May was also a time of celebration. The Romans held the Feriales and the Festival of Flora, honoring the goddess of flowers and spring. These celebrations underscored the season's significance as a time of blooming nature and fresh beginnings, reinforcing the symbolic link between emerald and the rejuvenation of life.
The emerald’s historical status as a birthstone has varied depending on the source. According to biblical interpretations, the birthstone for May was agate, while in Arabic traditions, emerald was the preferred gem. However, the modern standardized list of birthstones, formalized by the National Association of Jewelers (now known as the Jewelers of America) in 1912, designated emerald as the official May birthstone. This decision was influenced by the growing popularity of emerald in jewelry and its strong cultural associations with springtime and vitality.
The role of jewelry houses and retailers in popularizing the emerald as a birthstone cannot be overlooked. In the 19th century, Tiffany & Co. played a significant role in promoting the concept of birthstones through their publication of "Gregorian Birthstone Poems" in 1870. Their poem for May, for instance, reads:
"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 loving wife."
This poetic endorsement helped cement the emerald's place in the hearts of those born in May, associating it with themes of love, loyalty, and domestic happiness.
By the early 20th century, the emerald had firmly established itself as the quintessential May birthstone. Its allure continued to grow with the rise of the Art Deco period, when jewelers began incorporating emeralds into intricate designs that highlighted their brilliance and color. Today, the emerald remains a cherished symbol for May birthdays, representing not only the vibrancy of spring but also the enduring power of renewal and transformation.
Geological Formation and Sources of Emerald
Emerald, the May 16th birthstone, is a remarkable gemstone formed under specific geological conditions that give it its signature vibrant green color and extraordinary clarity. As a beryl mineral, emerald is composed of beryllium, aluminum, silicon, and oxygen, with its striking color derived from the presence of trace amounts of chromium or vanadium. This unique chemical composition sets emerald apart from other gemstones and contributes to its enduring appeal.
Emerald forms deep within the Earth’s crust through a process involving the interaction of hydrothermal fluids with igneous and metamorphic rocks. These fluids, rich in dissolved minerals, move through fractures and cavities in the rock, where they cool and deposit the elements necessary for emerald’s crystallization. The presence of chromium or vanadium in these fluids is crucial, as it determines the intensity of the emerald’s green color. Emeralds with higher concentrations of chromium tend to exhibit a richer, more saturated green, while those with vanadium may have a slightly bluish-green hue.
The formation of emerald is often associated with regions where pegmatite and mica schist rocks are present. Pegmatites are coarse-grained igneous rocks that form from the slow cooling of magma, and they are a primary source of emeralds. Mica schist, a metamorphic rock, also provides an ideal environment for emerald formation due to its high mineral content and the presence of fluid-rich fractures. These geological conditions are found in specific parts of the world, making emerald a relatively rare gemstone compared to others.
The primary sources of emerald today are concentrated in a few key regions, each known for producing emeralds with distinct characteristics. Colombia, the most renowned source of emeralds, is famous for its high-quality stones, which are often referred to as "Colombian emeralds." These emeralds are typically found in the Muzo and Chivor mines, where the geological conditions have produced some of the finest emeralds in the world. The emeralds from Colombia are prized for their deep green color, clarity, and brilliance.
Other significant sources of emeralds include Brazil, which is the largest producer of emeralds in the world. Brazilian emeralds are often found in the states of Minas Gerais, Bahia, and Goiás, and while they are generally less valuable than Colombian emeralds, they are still highly regarded for their quality. Zambia is another major source of emeralds, with the Kipushi and Kitwe mines producing stones of exceptional color and clarity. Zambian emeralds are known for their intense green hue, which is attributed to the presence of chromium.
In addition to these primary sources, emeralds have also been found in other parts of the world, including Afghanistan, Pakistan, Nigeria, and the United States. However, these regions typically produce smaller quantities of emeralds, and the stones from these locations are less well known in the global market. The rarity of emerald and the specific geological conditions required for its formation contribute to its value and desirability as a gemstone.
The process of extracting emeralds from the Earth is both complex and labor-intensive. Miners must carefully excavate emerald-bearing rocks, as emeralds are often found in narrow veins and are fragile due to their inclusions. These inclusions, while sometimes considered imperfections, are a natural part of emerald’s formation and can add to its character and uniqueness. Once extracted, emeralds undergo a series of treatments to enhance their appearance. These treatments may include oiling or resin infusion, which help to fill in surface fractures and improve the gemstone’s clarity and brilliance.
The geological rarity of emerald, combined with its historical and cultural significance, makes it a gemstone of enduring value. Whether found in the rich deposits of Colombia, the vast mines of Brazil, or the unique geology of Zambia, emeralds continue to captivate gemstone enthusiasts with their vibrant color and natural beauty.
Gemological Properties of the May 16th Birthstone
Emerald, the May 16th birthstone, is distinguished by its unique gemological properties, which contribute to its enduring appeal and value. As a member of the beryl family, emerald is composed of beryllium, aluminum, silicon, and oxygen, with its signature green color resulting from trace amounts of chromium or vanadium. This chemical composition gives emerald its remarkable optical properties and sets it apart from other gemstones.
One of the most defining characteristics of emerald is its color. The gemstone’s vibrant green hue ranges from a deep, rich green to a more delicate, bluish-green tone, depending on the concentration of chromium or vanadium. Chromium-rich emeralds typically display a more intense and saturated green color, while those with vanadium tend to have a slightly bluish tint. This variation in color makes emerald a versatile gemstone, suitable for a wide range of jewelry designs.
Emerald has a hardness of 7.5 to 8 on the Mohs scale, which means it is relatively durable but not as hard as diamonds, sapphires, or rubies. While this hardness level allows emeralds to be worn in various types of jewelry, it also means that they can be susceptible to scratches and chips if not handled with care. Additionally, emeralds often contain inclusions—internal flaws that are a natural result of their formation. These inclusions, often referred to as "jardin," are not considered flaws but rather a testament to the gemstone’s natural origin and authenticity.
The refractive index of emerald typically ranges from 1.57 to 1.58, which contributes to its brilliance and luster. When cut properly, emeralds can display a beautiful dispersion of light, enhancing their visual appeal. The most common cut for emeralds is the emerald cut, a rectangular step-cut that emphasizes the gemstone’s clarity and color. This cut is designed to protect the emerald’s fragile structure while showcasing its brilliance.
Emeralds are also known for their birefringence, a property that causes light to split into two rays as it passes through the gemstone. This optical effect can sometimes be observed as a slight doubling of facets or a hazy appearance, particularly in stones with high inclusions. However, this characteristic is not considered a flaw but rather a natural feature of emeralds.
The carat weight of emeralds varies depending on their size and quality. While small emeralds are often used in earrings and pendants, larger stones are highly prized for their rarity and beauty. Emeralds over 5 carats are considered particularly valuable, as they are relatively rare in the market.
Emeralds are typically found in a range of transparency levels, from transparent to translucent. Transparent emeralds are the most valuable, as they allow for maximum light penetration and brilliance. Translucent emeralds, while still beautiful, tend to have a more opaque appearance and are often used in more decorative applications.
The specific gravity of emerald ranges from 2.67 to 2.78, which is relatively high compared to other gemstones. This density contributes to the gemstone’s weight and gives it a solid, substantial feel when held. The combination of these gemological properties makes emerald a unique and highly sought-after gemstone, cherished for its color, clarity, and durability.
Emeralds are often treated to enhance their appearance and stability. The most common treatment involves the use of oils, resins, or waxes to fill surface fractures and improve clarity. These treatments are generally stable and do not significantly affect the gemstone’s overall appearance. However, it is important for buyers to be aware of any treatments applied to an emerald, as this can impact its value and care requirements.
The combination of emerald’s color, hardness, refractive properties, and inclusions makes it a gemstone of remarkable beauty and complexity. Whether set in a classic solitaire ring or incorporated into an intricate piece of jewelry, emeralds continue to captivate gemstone enthusiasts with their natural elegance and enduring appeal.

Care and Cleaning of the May 16th Birthstone
Proper care and maintenance are essential for preserving the beauty and longevity of emerald jewelry. Due to its unique gemological properties, emeralds require careful handling to prevent damage and ensure their brilliance remains undiminished. Understanding the best practices for cleaning, storing, and wearing emerald jewelry can help gemstone owners protect their investment and enjoy the gemstone’s vibrant beauty for years to come.
Emerald has a hardness of 7.5 to 8 on the Mohs scale, which means it is relatively durable but not as hard as diamonds, sapphires, or rubies. While this hardness allows emeralds to be worn in various types of jewelry, it also means that they can be susceptible to scratches and chips if not handled with care. Additionally, emeralds often contain inclusions—internal flaws that are a natural result of their formation. These inclusions, often referred to as "jardin," can make emeralds more fragile and prone to cracking if subjected to rough handling or sudden impacts.
When it comes to cleaning emeralds, it is important to use gentle methods that will not compromise the gemstone’s integrity. One of the most recommended cleaning techniques is using warm, soapy water and a soft-bristled brush. This method is effective for removing dirt and debris without damaging the emerald or its setting. To clean an emerald, mix a small amount of mild dish soap with warm water, then use a soft brush to gently scrub the gemstone and its surrounding metal. After scrubbing, rinse the emerald under warm water to remove any soap residue and dry it with a soft, lint-free cloth.
It is important to avoid using harsh chemicals or abrasive cleaners when cleaning emeralds, as these can damage the gemstone or its setting. Ultrasonic cleaners, which use high-frequency sound waves to remove dirt and debris, are generally not recommended for emeralds. The vibrations from these cleaners can potentially loosen the inclusions within the gemstone or cause micro-fractures to expand, leading to further damage. Steam cleaners should also be avoided for the same reason.
Emeralds are often treated with oils, resins, or waxes to enhance their appearance and stability.

However, it is important to be aware that excessive exposure to water or heat can cause these treatments to dissolve or evaporate, potentially affecting the gemstone’s appearance. To maintain the integrity of treated emeralds, it is best to avoid prolonged exposure to water or high temperatures.
When storing emerald jewelry, it is important to protect the gemstone from potential damage. Emeralds should be stored separately from harder gemstones such as diamonds, sapphires, and rubies to prevent scratches. A soft pouch or a lined jewelry box is an ideal storage solution for emeralds, as it provides a protective barrier against dust and physical contact. Additionally, it is a good idea to store emeralds in a cool, dry place to prevent exposure to excessive moisture or heat, which can affect the gemstone’s stability.
When wearing emerald jewelry, it is important to be mindful of activities that may pose a risk to the gemstone. Emeralds should be removed before engaging in physical activities such as sports, cleaning, or manual labor, as these can increase the likelihood of impact or abrasion. Additionally, it is advisable to avoid wearing emerald jewelry in environments with extreme temperatures or excessive humidity, as these conditions can affect the gemstone’s stability and appearance.
Regular inspection of emerald jewelry is also recommended to ensure that the gemstone and its setting remain in good condition. Over time, the prongs or settings that secure the emerald can become loose or damaged, increasing the risk of the gemstone becoming dislodged. If any signs of wear or damage are noticed, it is best to have the jewelry inspected and repaired by a professional jeweler.
By following these care and cleaning guidelines, emerald owners can ensure that their gemstone remains beautiful and intact for generations to come. Proper handling, cleaning, and storage are essential for preserving the gemstone’s natural beauty and value, allowing it to be enjoyed as a cherished heirloom.
