History and Lore
Turquoise has been cherished for millennia, with its earliest known use dating back to ancient Egypt. The stone was so valued that it was often referred to as "the stone of the gods." In ancient Egypt, turquoise was used in jewelry, amulets, and even in the adornment of mummies. It was believed to have protective properties and was associated with the gods, particularly the sky gods. The vibrant blue-green color of turquoise was thought to represent the heavens, and it was often used in religious and ceremonial contexts.
The use of turquoise extended beyond Egypt to other ancient civilizations, including the Persians, who were known for their intricate metalwork and inlay techniques. In the Americas, the Pueblo, Zuni, and Navajo peoples also held turquoise in high regard. It was used in jewelry, ceremonial regalia, and even as a form of currency. These Native American cultures believed that turquoise was a sacred stone that bridged the gap between the physical and spiritual worlds. It was often used in rituals and was thought to bring good fortune and protection.
In medieval Europe, turquoise was introduced through trade with the East. It became a symbol of nobility and was often used in royal jewelry. During the Renaissance, the stone gained popularity among the European aristocracy, who were fascinated by its exotic origins and vibrant color. The 18th and 19th centuries saw an increase in the production of turquoise jewelry, particularly in France and Britain, where it was incorporated into elaborate designs.
In the 20th century, turquoise experienced a revival, particularly in the American Southwest. The stone became a staple in Native American jewelry, where it continues to be used in traditional and contemporary designs. Today, turquoise is a popular gemstone in the jewelry industry, especially as a December birthstone. Its historical and cultural significance adds depth to its use in jewelry, making it a meaningful and timeless choice for those born in December.
Geological Formation and Sources
Turquoise is a hydrated phosphate of aluminum and copper, with the chemical formula CuAl₆(PO₄)₄(OH)₈·4H₂O. It is a relatively soft gemstone, with a hardness of 5 to 6 on the Mohs scale, which means it can be scratched by harder materials. The color of turquoise is primarily determined by the presence of copper, which gives it its characteristic blue to green hues. The intensity of the color can vary depending on the concentration of copper and the amount of hydration in the stone.
Turquoise is typically found in arid regions, where it forms in the oxidation zones of copper deposits. It is often found in association with other minerals such as quartz, calcite, and pyrite. The formation of turquoise is a slow process that occurs over thousands of years. It is usually found in veins or pockets within the host rock and is often mined using traditional methods due to its delicate nature.
Some of the most well-known sources of turquoise include:
- Iran (Persia): Known for producing some of the finest and most highly valued turquoise in the world. Persian turquoise is often a deep blue with minimal matrix (the dark veins that run through the stone).
- Mexico: Mexican turquoise is known for its vibrant blue color and often has a more pronounced matrix. It is a popular choice for jewelry and is widely used in the American Southwest.
- China: Chinese turquoise, also known as "Feitui," is another significant source. It is typically a greenish-blue and is often used in traditional Chinese jewelry.
- United States: The American Southwest, particularly in Arizona, Nevada, and New Mexico, is a major source of turquoise. The stone is often used in Native American jewelry and is highly prized for its quality and color.
The mining of turquoise is often a labor-intensive process, as the stone is brittle and can easily crack or chip. Artisans and jewelers often work with turquoise that has been stabilized to enhance its durability. Stabilization involves treating the stone with resins or other substances to improve its hardness and reduce porosity. This process allows turquoise to be used in a wider range of jewelry designs, including rings and bracelets, which would otherwise be impractical due to the stone’s softness.
Gemological Properties
Turquoise is a unique gemstone that stands out for its distinctive color and properties. Its color range typically spans from a deep, rich blue to a lighter greenish-blue. The most sought-after turquoise is a vivid blue with minimal matrix, while stones with a more pronounced matrix are also valued for their unique patterns. The color of turquoise can also be influenced by the presence of other minerals and the amount of hydration in the stone.
The stone is relatively soft, with a hardness of 5 to 6 on the Mohs scale. This makes it susceptible to scratches and abrasions, so it is important to handle turquoise jewelry with care. Turquoise is also porous, which means it can absorb oils and other substances, potentially affecting its color and appearance. To preserve the stone's beauty, it is recommended to keep it away from harsh chemicals and excessive moisture.
Turquoise has a refractive index of approximately 1.61 to 1.65, which means it does not have the same level of brilliance as harder gemstones like diamonds or sapphires. Instead, its beauty lies in its color and the patterns created by the matrix. The matrix, or the dark veins that run through the stone, adds character and individuality to each piece of turquoise. These patterns can vary widely, making each stone unique.
In terms of transparency, turquoise is typically opaque, meaning that it does not allow light to pass through it. This is in contrast to transparent gemstones like diamonds or sapphires, which allow light to pass through and create a sparkle. The opacity of turquoise gives it a solid, earthy appearance that is often described as calming and soothing.
The carat weight of turquoise is not typically used to determine its value, as the stone is usually cut into cabochons rather than faceted gemstones. Cabochons are smooth, rounded stones that are often used in jewelry to display the stone's natural color and patterns. The size of the cabochon can vary, but it is usually chosen based on the design of the jewelry piece.
The cut of turquoise is an important factor in its appearance. Artisans often use traditional techniques to shape and polish the stone, ensuring that it retains its natural beauty while enhancing its color and luster. The polishing process is particularly important for turquoise, as it helps to bring out the stone's vibrant color and smooth surface.
Symbolism and Metaphysical Beliefs
Turquoise has long been associated with a wide range of symbolic and metaphysical properties. In many ancient cultures, it was considered a stone of protection, believed to ward off evil and bring good fortune. It was also associated with the heavens and the divine, often used in religious and ceremonial contexts. In ancient Egypt, turquoise was thought to connect the wearer to the gods, particularly the sky gods. It was used in amulets and jewelry to provide protection and to ensure a safe passage to the afterlife.
In Native American cultures, turquoise is considered a sacred stone. It is believed to bring good luck, protection, and healing. The stone is often used in rituals and ceremonies, where it is worn as a talisman to connect with the spiritual world. The Navajo, in particular, use turquoise in their jewelry and regalia, believing it to be a powerful symbol of life and vitality. It is also associated with the earth and the sky, representing the bridge between the physical and spiritual realms.
In medieval Europe, turquoise was believed to have protective properties and was often used in royal jewelry. It was thought to bring wisdom, truth, and clarity of thought. During the Renaissance, it was also associated with nobility and was used in elaborate designs to symbolize status and wealth.
In modern times, turquoise continues to be valued for its symbolic meaning. It is often associated with tranquility, calmness, and emotional balance. It is believed to help reduce stress and promote a sense of peace and well-being. It is also associated with communication and self-expression, making it a popular choice for those who seek to improve their ability to express themselves.
In the context of jewelry, turquoise is often used in pieces that are designed to be worn close to the heart. Locket necklaces, in particular, are a meaningful choice, as they can hold a personal memento such as a photograph or a lock of hair. The stone's association with protection and healing makes it a fitting choice for such a piece, as it is believed to offer emotional support and comfort to the wearer.
The metaphysical properties of turquoise have also made it a popular choice in crystal healing and alternative medicine. It is believed to have a calming effect on the body and mind, helping to reduce anxiety and promote relaxation. It is also used in meditation practices to enhance focus and clarity of thought.
In summary, turquoise is a gemstone that carries a rich history of symbolic and metaphysical significance. Its association with protection, healing, and emotional balance makes it a meaningful choice for jewelry, particularly in the form of a locket necklace. Whether worn for its beauty, its history, or its symbolic meaning, turquoise continues to be a treasured gemstone that holds a special place in the world of jewelry and gemology.
Care and Cleaning
Given its relatively soft nature and porosity, turquoise requires special care to maintain its appearance and durability. To protect the stone from damage, it is important to avoid exposure to harsh chemicals, such as household cleaners, perfumes, and lotions. These substances can cause the stone to become discolored or lose its luster over time. It is also advisable to remove turquoise jewelry before engaging in activities that may expose it to physical impact or abrasion, such as sports or manual labor.
Turquoise should be stored in a cool, dry place, away from direct sunlight and sources of heat. Exposure to excessive heat can cause the stone to dry out and become brittle, increasing the risk of cracking or chipping. When storing turquoise jewelry, it is best to wrap the pieces in a soft cloth or place them in a jewelry box with individual compartments to prevent scratches and abrasions.
Cleaning turquoise should be done with care to avoid damaging the stone. A gentle approach is recommended, using a soft, lint-free cloth to wipe the surface of the stone. If the stone requires a more thorough cleaning, a mild solution of warm water and a small amount of dish soap can be used. The jewelry should be soaked in the solution for a few minutes, then gently wiped with a soft cloth. It is important to avoid using ultrasonic cleaners or steam cleaners, as these can cause the stone to become dry and lose its color.
After cleaning, turquoise should be dried thoroughly with a soft cloth to prevent moisture from being trapped in the stone. This is particularly important for stabilized turquoise, as the resins used in the stabilization process can be affected by prolonged exposure to water.
In the case of locket necklaces, it is important to ensure that the mechanism of the locket is functioning properly and that the stone is securely set. If the locket is opened and closed frequently, it is advisable to do so gently to avoid putting stress on the setting. If the locket becomes loose or damaged, it should be taken to a professional jeweler for repair.
Overall, proper care and maintenance are essential for preserving the beauty and longevity of turquoise jewelry. By following these guidelines, wearers can ensure that their turquoise pieces remain in excellent condition, retaining their vibrant color and luster for years to come.
