The rich, sky-blue to verdant-green hues of turquoise have captivated humanity for millennia. As one of the oldest known gemstones in human history, it carries a legacy woven through ancient civilizations, royal adornments, and modern jewelry collections. Recognized universally as the primary birthstone for the month of December, turquoise holds a special place in the hearts of those born in the final month of the year. Its distinctive color, often mimicking the clear winter skies or the deep waters of the tropics, makes it a gem of profound symbolic and aesthetic value.
This article explores the multifaceted nature of turquoise, delving into its historical journey, geological origins, gemological characteristics, and its enduring symbolism. Furthermore, within the contemporary jewelry landscape, brands like Pandora have played a significant role in popularizing this ancient stone through modern design. We will specifically examine the turquoise birthstone's expression within Pandora's December birthstone charms, analyzing how this historic gem is presented to a global audience of enthusiasts and collectors.
History and Lore of Turquoise
Turquoise is arguably one of the most culturally significant gemstones, with a history that spans across continents and epochs. The name "turquoise" is derived from the French phrase pierre turquoise, meaning "Turkish stone." This nomenclature reflects the gem's historical trade route, originating in Persia (modern-day Iran) and passing through Turkish markets before reaching Europe. However, the stone's origins and usage predate these trade routes by thousands of years.
Ancient civilizations, particularly in the Americas, held turquoise in the highest regard. For the ancient Egyptians, turquoise was a symbol of protection and rebirth. It was extensively used in the funerary adornments of pharaohs, most notably Tutankhamun, whose burial mask was inlaid with significant quantities of the gem. The Egyptians mined turquoise from the Sinai Peninsula as early as 3000 B.C., establishing one of the earliest known turquoise mining operations.
In the American Southwest, turquoise became the cornerstone of spiritual and artistic expression for Indigenous peoples, including the Navajo, Zuni, and Pueblo tribes. For these cultures, turquoise was not merely a decorative stone but a living entity—a piece of the sky fallen to earth. It was used in ceremonial objects, jewelry, and as an offering to the gods. The stone was believed to be a conduit between the earthly and spiritual realms, offering protection during travel and ensuring health and safety.
The journey of turquoise from an ancient talisman to a modern birthstone is a relatively recent development. The standardization of birthstones is largely attributed to the National Association of Jewelers (now Jewelers of America), which published a definitive list in 1912. This list designated turquoise as the birthstone for December, a designation that has remained consistent in the United States and has been adopted by many other cultures worldwide. This formal recognition cemented turquoise's status, ensuring its continued relevance in the jewelry market and its association with those born in the winter month.
Geological Formation and Mining Sources
Understanding the formation of turquoise provides insight into its unique characteristics and variations. Turquoise is a hydrous phosphate mineral containing copper and aluminum. Its formation is a geological anomaly, occurring in arid regions where acidic waters percolate through rocks rich in aluminum and copper, depositing the minerals into cracks and voids. Over geological time, these deposits solidify into the nodular or vein-like forms of turquoise.
The gemstone is rarely found as a single, flawless crystal. Instead, it typically occurs in massive, botryoidal, or reniform habits. The presence of the host rock, often sandstone or limestone, can become incorporated into the turquoise during formation, resulting in the matrix patterns seen in many specimens. The "spiderweb" matrix, where the host rock creates a web-like pattern within the blue-green gem, is a highly prized characteristic, particularly in American turquoise.
Geographically, turquoise sources are scattered across the globe, each producing stones with distinct color palettes and matrix patterns.
- Iran (Persia): Historically the most significant source, Persian turquoise is renowned for its "sky blue" or "robin's egg blue" color, often with little to no matrix. The Nishapur district remains the primary mining area, producing some of the finest quality turquoise in the world.
- United States: The American Southwest is home to some of the most famous turquoise mines, including those in Nevada, Arizona, and New Mexico. Nevada mines such as Lander Blue, Royston, and Turquoise Mountain produce a wide spectrum of colors, from light blue to deep green, often with striking black or brown matrix patterns. Arizona's Kingman mine is known for its distinctive blue with a black matrix.
- China: In recent decades, China has become a major producer of turquoise, primarily from the Hubei province. Chinese turquoise ranges from light blue to green and is often treated to enhance its color and durability.
- Other Sources: Significant deposits are also found in Afghanistan, Chile, and Australia.
The color of turquoise is directly linked to its copper content; higher copper levels yield a vibrant blue, while higher iron content results in a greenish hue. The geological environment determines these trace element concentrations, leading to the vast color diversity observed in the gemstone.
Gemological Properties
Turquoise possesses a unique set of gemological properties that define its appearance, durability, and value. While it is a relatively soft and porous gem compared to diamonds or sapphires, its distinct color and rarity make it a favorite for jewelry, particularly in cabochon cuts.
The following table outlines the key gemological properties of turquoise:
| Property | Description |
|---|---|
| Chemical Formula | CuAl₆(PO₄)₄(OH)₈·4H₂O (Hydrated Copper Aluminum Phosphate) |
| Crystal System | Triclinic (though rarely seen in distinct crystals) |
| Color | Sky blue, green-blue, apple green; often banded or mottled with a brown or black matrix. |
| Hardness (Mohs Scale) | 5 to 6 (can vary due to porosity and water content) |
| Refractive Index | 1.610 to 1.650 |
| Luster | Waxy to subvitreous (when polished) |
| Transparency | Opaque |
| Toughness | Fair to good (susceptible to cracking if subjected to thermal shock) |
Color and Clarity: The most prized color for turquoise is a uniform, intense sky blue, free from mottling or matrix. However, many collectors value the matrix patterns, considering them an integral part of the stone's character. Because turquoise is almost always opaque, clarity is not graded in the same manner as transparent gems. Inclusions, particularly the host rock matrix, are expected.
Durability and Care: With a Mohs hardness of 5 to 6, turquoise is relatively soft. It is susceptible to scratching by materials harder than itself and can be damaged by acids, cosmetics, and even skin oils. It is also porous, meaning it can absorb liquids, leading to discoloration. Consequently, turquoise jewelry requires careful handling and regular maintenance.
Treatments and Stabilization: It is common practice in the gem trade to treat turquoise to enhance its color and durability. Stabilization involves impregnating the porous stone with a clear resin or wax, which locks in color and reduces porosity. This process makes the stone more suitable for jewelry and less prone to discoloration. Many commercial-grade turquoise, including that used in mass-market jewelry, is stabilized. Dyed and reconstituted turquoise (made from powdered turquoise mixed with a binder) are also common treatments but are generally less valuable than natural or stabilized stones.
Symbolism and Metaphysical Beliefs
Beyond its physical beauty, turquoise is imbued with a rich tapestry of symbolic meanings and metaphysical beliefs. These attributes have evolved over centuries, drawing from diverse cultural traditions.
Protection and Healing: Historically, turquoise is foremost a protective stone. Ancient warriors would attach turquoise to their weaponry or wear it as an amulet to deflect injury. In Persian and Turkish lore, it was believed to ward off the "evil eye" and protect the wearer from unnatural death. It was also widely used as a healing stone, thought to cure ailments of the head, neck, and chest, and to regulate the body's chemistry.
Communication and Serenity: In metaphysical circles, turquoise is associated with the Throat Chakra, governing communication and self-expression. It is believed to foster honest and clear communication, helping the wearer articulate their thoughts and feelings. Furthermore, the stone is said to possess a calming energy, promoting inner peace, tranquility, and emotional balance. It is often recommended for those who suffer from anxiety or excessive nervous energy.
December Birthstone Significance: For those born in December, turquoise is said to bring luck, prosperity, and protection. It is considered a stone of friendship and love, often gifted to signify affection and trust. Its connection to the winter month aligns with themes of clarity, purity (like a clear winter sky), and renewal as the year closes.

Care and Cleaning
Due to its physical properties, turquoise requires specific care to maintain its beauty and integrity. It is not a gemstone that can be treated with the same harsh methods used for harder stones.
- Avoid Chemicals: Turquoise is highly susceptible to damage from chemicals, including acids, alkalis, perfumes, lotions, and hairspray. These substances can erode the stone's surface and cause permanent discoloration. Jewelry should be the last item put on and the first taken off.
- Gentle Cleaning: The best method for cleaning turquoise is warm, soapy water and a soft brush. Rinse thoroughly to remove any soap residue. Avoid ultrasonic cleaners and steam cleaners, as the heat and vibrations can cause cracking or crazing (a fine network of surface cracks), especially in untreated or porous stones.
- Storage: Store turquoise jewelry separately from other gems and metals to prevent scratching. It is best kept in a soft cloth pouch or a lined jewelry box. Because turquoise can dry out and lose its color over time, some collectors recommend storing it with a small, damp piece of cotton in a sealed container to maintain humidity, though this is less necessary for stabilized stones.
- Stabilized vs. Natural: It is important to know if the turquoise is stabilized. Stabilized turquoise is more resistant to color change and absorbing liquids, making it slightly easier to care for. However, all turquoise should be handled with care to avoid scratches and physical damage.
Conclusion
Turquoise stands as a testament to the enduring power of gemstones to connect us to history, nature, and personal identity. As the birthstone of December, it carries a legacy of protection, communication, and serenity that has been cherished for thousands of years. Its journey from the ancient mines of Persia and the American Southwest to the display cases of modern jewelers highlights its universal appeal.
While its gemological properties—a moderate hardness and porous nature—demand careful handling, they also contribute to its unique character, often displaying intricate matrix patterns that tell the story of its geological formation. The gemstone's symbolism remains potent, offering a sense of calm and protection to its wearer.
