The concept of a birthstone for a specific day, such as December 8th, is a modern interpretation of an ancient tradition. Unlike the traditional monthly birthstones, which have been standardized over centuries, daily birthstones are a more recent development, often linked to the birthstone chart published by the American Gem Society (AGS) in 2016. For those born on December 8th, the designated birthstone is Turquoise. This vibrant, sky-blue to greenish-blue gem has been cherished for millennia, embodying themes of protection, wisdom, and tranquility. Its selection for this date connects individuals to a rich tapestry of geological rarity, historical significance, and metaphysical lore. This article explores the multifaceted nature of the December 8th birthstone, delving into its geological origins, gemological properties, historical journey, and the symbolism that makes it a timeless emblem of personal identity.
The December 8th birthstone, Turquoise, is part of a broader family of December gems. The month of December is uniquely associated with five traditional birthstones: Zircon, Topaz, Tanzanite, Lapis Lazuli, and Turquoise. This diversity offers a palette of choices, from the fiery brilliance of Zircon to the deep celestial blue of Lapis Lazuli. However, Turquoise stands out for its distinctive opaque to semi-translucent quality and its long-standing association with ancient civilizations. Understanding the December 8th birthstone requires appreciating its place within this larger group, recognizing its unique characteristics, and exploring the cultural narratives that have elevated it from a simple mineral to a symbol of enduring appeal and individuality.
History and Lore
The historical journey of Turquoise is as complex and layered as the stone itself. As the designated birthstone for December 8th, it inherits a legacy that spans continents and millennia. While the specific association of Turquoise with December 8th is a modern convention, the gem’s own history is ancient and profound. Sources indicate that Turquoise has been mined and revered for over 6,000 years. The earliest known evidence of Turquoise mining dates to ancient Egypt, where the stone was extracted from the Sinai Peninsula. It was prized by Egyptian pharaohs and artisans, who carved it into protective amulets, intricate beads, and elaborate inlays for jewelry and funerary objects, such as Tutankhamun’s famous burial mask, which featured extensive Turquoise inlay.
The name “Turquoise” itself is derived from the French phrase pierre turquoise, meaning “Turkish stone,” reflecting the historical trade routes through which the gem reached Europe. The primary source for this trade was the mines in Persia (modern-day Iran), which have been producing high-quality Turquoise for centuries. Persian Turquoise, particularly from the Nishapur region, is renowned for its robin’s-egg blue color and is often considered the benchmark for quality. In ancient Persia, Turquoise was a sacred stone, believed to ensure divine favor and protection. It was inlaid into domes, mosques, and royal objects, symbolizing paradise and heaven.
Beyond the Middle East and North Africa, Turquoise was independently discovered and highly valued by indigenous cultures in the Americas. In the Southwestern United States, the Anasazi, Hohokam, and Pueblo peoples mined and worked with Turquoise as early as 200 B.C. For these cultures, the stone was not merely decorative but deeply spiritual, often used in ceremonies, as a medium of exchange, and as a protective talisman. The Zuni and Navajo tribes, in particular, are famous for their intricate Turquoise and silver jewelry, a tradition that began in the 19th century after the arrival of Spanish silversmiths. This art form has become a defining element of Native American jewelry and a significant part of the gem’s modern identity.
The association of gemstones with specific months and dates has its roots in ancient traditions, often linked to astrological beliefs and the perceived influence of celestial bodies. While the precise origins of this tradition are debated, it is clear that gemstones were considered to hold symbolic power and were believed to impact the wearer’s life. The December 8th birthstone, therefore, inherits this legacy of meaning and significance. It is not merely a decorative object but a connection to centuries of human experience and belief. The specific designation for December 8th is a contemporary interpretation, allowing individuals to forge a personal connection with a gemstone that has been universally admired for its beauty and perceived virtues.
Geological Formation and Sources
Turquoise is a phosphate mineral with the chemical formula CuAl₆(PO₄)₄(OH)₈·4H₂O. Its formation is a geological rarity, requiring a specific and unusual combination of elements and conditions. Turquoise is a secondary mineral, meaning it forms through the alteration of pre-existing rocks. It typically occurs in arid or semi-arid regions where acidic, copper-rich water percolates through aluminum-rich rocks, such as feldspar-rich porphyry. Over millions of years, this process leads to the deposition of Turquoise in veins, nodules, or as a matrix replacement in the host rock.
The color of Turquoise, which ranges from sky blue to apple green, is primarily determined by the presence of copper (which produces blue hues) and iron (which produces green hues). The level of iron content and the presence of other trace elements create the wide spectrum of colors found in natural Turquoise. The stone’s opacity is due to the presence of microscopic inclusions and its porous, often waxy, texture.
The world’s most significant Turquoise deposits are found in a handful of locations, each producing stones with distinct characteristics:
- Iran (Persia): The Nishapur region in northeastern Iran has been the source of the finest, most highly prized Turquoise for centuries. Persian Turquoise is celebrated for its even, sky-blue to robin’s-egg blue color, often with a subtle waxy luster. It is typically found in veins within a dark, host rock matrix.
- United States: The Southwestern states, particularly Arizona, New Mexico, and Nevada, are major producers of Turquoise. The region is home to hundreds of historical and active mines, each yielding stones with unique colors and matrix patterns. Famous mines include the Sleeping Beauty mine in Arizona (known for its pure, sky-blue, matrix-free stone), the Morenci mine (characterized by a dark, spiderweb matrix), and the Carico Lake mine in Nevada (producing a rare, greenish-blue to blue-green color). American Turquoise is highly diverse, with each mine’s output possessing a distinct "fingerprint" that is cherished by collectors and artisans.
- China: China is a significant producer of Turquoise, with deposits primarily in the Hubei province. Chinese Turquoise varies in color and quality, with some mines producing material that can rival Persian and American stones in color and texture.
- Other Sources: Smaller deposits exist in Afghanistan, Chile, Egypt, and Mexico, each contributing to the global supply of this beloved gem.
The matrix—the host rock that remains attached to the Turquoise—plays a crucial role in the stone’s appearance and value. Some Turquoise is "matrix-free," appearing as solid, uniform color. Other specimens feature a "spiderweb" or "chunky" matrix, where the host rock creates intricate, web-like patterns within the blue or green stone. The appreciation for matrix is a matter of personal taste, with some preferring the clean look of solid color and others valuing the unique, natural patterns of matrix-included stones.
Gemological Properties
Understanding the gemological properties of Turquoise is essential for appreciating its durability, care requirements, and value. While the provided sources do not offer a detailed gemological report for the December 8th birthstone specifically, they provide insights into the properties of the broader December birthstones, which include Turquoise. The following properties are well-established in gemological literature and are consistent with the general descriptions found in the sources.
Color: Turquoise is prized for its unique blue to greenish-blue color. The most valued hues are a vivid, medium blue, often described as "robin's-egg blue" or "sky blue." Greenish tones, resulting from higher iron content, are also common and can be highly desirable, especially in specimens from specific mines like those in Nevada.
Luster: Turquoise has a waxy to subvitreous (glass-like) luster. When polished, it can achieve a high shine, but its luster is typically softer than that of transparent gemstones.
Transparency: Turquoise is almost always opaque, meaning light does not pass through it. Some very high-quality, thin specimens may exhibit slight translucency, but this is rare.
Hardness: On the Mohs scale of mineral hardness, Turquoise ranges from 5 to 6. This makes it a relatively soft gemstone compared to others like quartz (hardness 7) or diamond (hardness 10). Its moderate hardness means it can be scratched or abraded with improper handling, making it essential to store it separately from harder jewelry pieces.
Durability and Treatments: Turquoise is a porous gemstone, which makes it susceptible to absorbing oils, chemicals, and even skin oils, which can alter its color over time. To enhance its durability, color, and stability, most commercial Turquoise undergoes some form of treatment. Common treatments include: * Waxing or Oiling: Applying a colorless wax or oil to fill surface pores and enhance luster and color. * Stabilization: Impregnating the stone with a clear resin or polymer under pressure to increase hardness, reduce porosity, and lock in color. Stabilized Turquoise is more durable and less likely to change color with wear, and it is widely used in jewelry today. * Dyeing: Some lower-quality, porous stones are dyed to achieve a more uniform or desirable color. This treatment is less stable and can fade over time.
The sources mention that the December birthstones, including Turquoise, are "suitable for jewelry and personal adornment, potentially exhibiting brilliance, clarity, and a range of colors." While Turquoise is not known for brilliance or clarity in the same way as transparent gems like Zircon or Topaz, its opaque beauty and unique color make it highly suitable for jewelry. Its value is determined by color, uniformity, hardness (which affects durability), the quality of the matrix (if present), and the size of the specimen.
Symbolism and Metaphysical Beliefs
The December 8th birthstone is imbued with a range of symbolic meanings and metaphysical beliefs, drawing upon the traditions associated with the broader December birthstones. While specific references to December 8th are limited, the symbolism of Turquoise offers profound insight into the potential meanings of the gem chosen for this date.
Turquoise has long been associated with protection, wisdom, and serenity. In many cultures, it is considered a talisman that wards off negative energy and harm. Ancient Egyptian warriors wore Turquoise amulets into battle for protection, and it was believed to change color to warn its owner of impending danger. This protective quality is a cornerstone of its lore.
Metaphysically, Turquoise is often linked to communication and emotional balance. It is believed to promote honest self-expression and clarity of thought, helping the wearer to speak their truth with confidence. This aligns with the symbolic meanings of other December birthstones, such as Zircon (associated with wisdom and spiritual insight) and Topaz (linked to calmness and serenity). The calming, blue-green hues of Turquoise are thought to have a soothing effect on the mind and spirit, reducing stress and promoting inner peace.
In many Native American cultures, Turquoise is revered as a sacred stone, a piece of the sky that fell to earth. It is believed to connect the wearer to the spiritual world and to the natural elements, particularly water and sky. The stone is often used in ceremonies and is thought to bring good fortune and health.
The symbolism of Turquoise extends to concepts of friendship and love. It is often given as a token of affection and is believed to strengthen bonds between people. Its association with the heart chakra in some spiritual traditions suggests it promotes compassion and unconditional love.
For the individual born on December 8th, the Turquoise birthstone can be seen as a symbol of their unique identity. Its vibrant, yet calming color reflects a personality that is both expressive and serene. Its historical legacy of protection and wisdom can be interpreted as a source of strength and guidance. The stone’s connection to the natural world serves as a reminder of the importance of balance and harmony in one’s life.
Care and Cleaning
