While the provided chunks do not specify these ancient origins, the gem’s historical significance is implied by its continued reverence and its designation as a birthstone.
The path to its modern status as a May birthstone is more clearly defined. The contemporary list of birthstones, which assigns emerald to May, is largely derived from the standards set by the National Association of Jewellers (now the British Jewellers' Association) in 1912, and later adopted by the American Gem Trade Association (AGTA). This list standardized the gemstones associated with each month, bringing a level of consistency to the tradition. The provided source material from costarimports.com explicitly lists "May - Emerald" under its "Birthstone Bands" section, confirming its official status. This modern codification has solidified the emerald’s role, ensuring its place in the jewelry collections of those born in the spring month.
Beyond its official designation, emerald has been steeped in lore across various cultures. It has been associated with the goddess Venus, the planet Mercury, and the element of earth. The stone is often linked to themes of fertility, rebirth, and immortality, making it a powerful symbol in many ancient societies. While the provided sources do not elaborate on these specific myths, the gemstone’s enduring popularity in jewelry design, as evidenced by the numerous emerald-centered pieces in the catalogs, speaks to its lasting symbolic power and cultural resonance.
Geological Formation and Sources
Emerald is a variety of the mineral beryl (Be₃Al₂(SiO₃)₆), and its characteristic green color is primarily caused by trace amounts of chromium and, in some cases, vanadium. The formation of emerald is a complex geological process that requires specific conditions: the presence of beryllium and aluminum, along with chromium or vanadium, and the right temperature and pressure, often in tectonic plate boundaries where these elements can interact.
The provided materials do not specify the geological formation process, but they do hint at the gemstone's origins through its market presence. The sources listed for the "Emerald Bands" and other jewelry pieces are commercial retailers like costarimports.com and thelordofgemrings.com. These companies likely source their emeralds from the major mining regions of the world. The most significant sources of emeralds today include Colombia, which is famed for its high-quality, deeply saturated green stones with a characteristic "jardin" (French for garden), referring to the natural inclusions that are often seen as a hallmark of authenticity. Other important sources include Zambia, Brazil, and Zimbabwe.
While the provided chunks do not name specific mining countries, the global trade in emeralds is well-documented. The gemstone's value is heavily influenced by its origin, with Colombian emeralds typically commanding the highest prices due to their superior color and clarity. The commercial listings in the sources, such as the "Emerald & Diamond Birthstone Band" priced at $1,750 and the more elaborate "Channel Set Emerald Baguette & Round Diamonds Border Band" at $4,250, reflect the market's valuation of the stone. The inclusion of emerald in multi-gemstone bands, like the "Birthstone Multicolor Fashion Band," further illustrates its versatility and desirability in the jewelry market, regardless of its specific geographic origin.
Gemological Properties
Emerald possesses a distinct set of physical and optical properties that define its identity as a gemstone. Understanding these properties is crucial for both gemologists and consumers.
Hardness and Durability: On the Mohs scale of mineral hardness, beryl, the parent mineral of emerald, has a hardness of 7.5 to 8. This makes emerald a relatively durable gemstone, suitable for various types of jewelry. However, its durability is tempered by its "cleavage" – a tendency to break along specific planes. Emerald has imperfect cleavage, which means it is more susceptible to chipping or cracking if subjected to a sharp blow. This is a critical consideration in jewelry design and setting. The provided product listings from costarimports.com feature emeralds in bands that are often set with diamonds. For example, the "Emerald & Diamond Birthstone Band" and the "Alternating Emerald Diamond Pave Band" ($3,000) use protective settings like milgrain and pave to secure the stones, which is a common practice to mitigate the risk of damage.
Color and Clarity: The most prized color for an emerald is a vivid, intense green with a slightly bluish undertone, free from overly dominant yellow or brown hues. The clarity of emeralds is typically evaluated differently from other gemstones like diamonds. Inclusions are common and are often accepted as a natural characteristic of the stone. These inclusions, sometimes forming patterns resembling foliage, are referred to as the "jardin." The provided materials do not specify the clarity or color grading of the emeralds used in their products, but the pricing and descriptions suggest a range of qualities. The "Channel Set Emerald Baguette & Round Diamonds Border Band" at $4,250 likely features higher-quality emeralds compared to more affordable pieces.
Cut and Carat Weight: Emeralds are frequently cut into rectangular step cuts, such as the emerald cut or Asscher cut, which are designed to enhance the stone's color and protect its edges. The provided sources list "Emerald Bands" and "Asscher Bands" as categories, indicating that these cuts are popular for emeralds in band designs. Carat weight is a significant factor in pricing; larger emeralds are rarer and more valuable. The product listings show emeralds used as accent stones in bands, often alongside diamonds, suggesting a focus on designs that incorporate emeralds of various carat weights to fit different price points.
Chemical and Optical Properties: As a variety of beryl, emerald has the chemical formula Be₃Al₂(SiO₃)₆. Its refractive index typically ranges from 1.577 to 1.583, and its birefringence is from 0.006 to 0.008. These properties contribute to its brilliance and luster. While the provided sources do not list these specific scientific details, they are fundamental to the gemological identification of emerald.
