Turquoise, the December birthstone, is a captivating gemstone known for its distinctive blue-green hues and intricate matrix patterns. With a history that spans millennia, it has been revered across civilizations for its aesthetic appeal and symbolic meanings. This semi-translucent to opaque gemstone has been cherished by ancient Egyptians, Native American tribes, and Persian artisans, among others. Turquoise is not only admired for its beauty but also for its rich associations with health, protection, and spiritual growth. In this article, we delve into the geological properties, historical significance, metaphysical beliefs, and practical care of this timeless gemstone.
History and Lore
Turquoise has a storied history that reflects its widespread cultural importance. It was first mined in ancient Egypt and used in jewelry and decorative objects. The word "turquoise" itself is derived from the French term for "Turkish," as the gemstone was introduced to Europe via Turkey from Persian mines. The gemstone's journey into European awareness in the 13th century marked the beginning of its global recognition.
In ancient Egypt, turquoise was considered a sacred stone. Pharaohs and other rulers adorned themselves with it, believing it to guarantee health, good fortune, and protection. The gemstone was also used in funerary art and amulets, symbolizing life and immortality. Egyptian artisans carved turquoise into various forms, and it was often combined with gold and lapis lazuli to create intricate jewelry and ceremonial objects.
The Aztecs and other indigenous peoples of Mesoamerica also valued turquoise highly. They used it in everything from ceremonial objects to weaponry, attributing spiritual and protective qualities to the stone. In the American Southwest, turquoise played an essential role in the art and culture of Native American tribes. The Apache believed that following a rainbow to its end would lead to the location of turquoise. They also believed that attaching the stone to a bow or firearm improved one's aim. The Pueblo people maintained that turquoise derived its color from the sky, while the Hopi believed the gem was produced by lizards scurrying over the earth.
Turquoise was added to the list of modern birthstones in the early 20th century. Prior to 1912, December was associated with bloodstone. The American National Association of Jewelers adopted the modern list of birthstones in 1912, which included turquoise as the December birthstone. This decision reflected the gemstone’s growing popularity and its longstanding cultural significance.
Geological Formation and Sources
Turquoise is a phosphated aluminum mineral with the chemical formula Al₂(OH)₃PO₄. It forms in the oxidized zones of copper deposits through the interaction of water, copper, aluminum, and phosphorus minerals over millions of years. This process results in a semi-translucent to opaque gemstone with a wide range of colors, from deep blue to pale green. The color variation is influenced by the presence of different minerals and the amount of water in the stone.
The matrix patterns in turquoise refer to the veins and flecks of the host rock in which it formed. These patterns can range from white to black, with black matrix patterns often being highly sought after for their dramatic contrast. The most prized turquoise is known for its vivid blue color and distinct matrix patterns. The term "Persian Blue" is used to describe the most valuable and vibrant turquoise, traditionally mined in Persia (modern-day Iran).
Turquoise is found in various parts of the world, including the United States, Iran, China, Egypt, and Mexico. The American Southwest, particularly Arizona and New Mexico, is known for producing high-quality turquoise. These regions have been significant sources of turquoise for centuries, with Native American artisans playing a crucial role in its cultural and artistic use.
Gemological Properties
Turquoise has a hardness of 5 to 6 on the Mohs scale, making it relatively soft compared to other gemstones. This hardness level means that turquoise is susceptible to scratches and requires careful handling and storage. The gemstone is also porous, which allows it to absorb oils and chemicals easily. This characteristic can lead to changes in color over time, especially when exposed to sunlight, oils, or treated water.
Turquoise is typically cut into cabochons, beads, or other shapes to enhance its natural beauty and minimize the risk of damage. The unique matrix patterns and color variations make each piece of turquoise distinctive. When cut and polished, turquoise exhibits a waxy to greasy luster, adding to its visual appeal.
The gemstone's chemical composition and formation process contribute to its physical properties. Turquoise is a hydrous mineral, meaning it contains water within its structure. This water content affects the stone's stability and color. Natural turquoise may darken when exposed to oils, sunlight, or chemicals, while stabilized turquoise, which has been treated to enhance its durability and color, retains its appearance better.
Symbolism and Metaphysical Beliefs
Turquoise has been attributed with numerous symbolic and metaphysical properties across different cultures. In ancient times, it was believed to possess protective and healing qualities. The 13th century saw the belief that turquoise could protect the wearer from falling, especially off horses, and would break into several pieces at the approach of disaster. Hindu mystics maintained that seeing turquoise after beholding the new moon ensured fantastic wealth.
In modern times, turquoise is considered a powerful stone with metaphysical properties. It is believed to balance and align the chakras, enhance spiritual growth and self-expression, and provide protection against negative energy. Turquoise is also associated with wisdom, luck, and good fortune. In astrology, it is linked to the zodiac sign Sagittarius and is considered a birthstone for the month of December. It is believed to encourage enthusiasm, attract prosperity, and bring success and understanding.
From a spiritual perspective, turquoise is associated with the throat and heart chakras, promoting communication and emotional healing. It is thought to enhance one's ability to express thoughts and feelings clearly, making it a popular choice for those seeking to improve their communication skills. Additionally, turquoise is believed to promote self-acceptance and reduce emotional burdens, making it a valuable tool for emotional healing.
In practical terms, turquoise is often used in jewelry and decorative objects. It is believed to bring good fortune and protection to the wearer. The ancient Egyptians, Persians, and Native Americans, among others, wore turquoise as an amulet to ward off evil and bring good luck. Today, turquoise continues to be valued for its spiritual and symbolic meanings, making it a meaningful choice for jewelry and personal adornment.
Care and Cleaning
Due to its softness and porosity, turquoise requires special care to maintain its beauty and longevity. Exposure to oils, sunlight, and chemicals can cause the gemstone to darken or change color over time. To protect turquoise, it should be stored in a cool, dry place away from direct sunlight and other gemstones that may cause scratches.
When cleaning turquoise, it is essential to avoid using harsh chemicals or ultrasonic cleaners. Instead, gently wipe the stone with a soft, damp cloth to remove any dirt or dust. If necessary, a mild soap solution can be used, but the stone should be rinsed thoroughly and dried immediately with a soft cloth. It is best to avoid exposing turquoise to treated water, such as chlorinated water from swimming pools, as it can damage or alter the color of the stone.
For those who believe in the metaphysical properties of turquoise, there are also methods for cleansing and recharging the stone. Some practices involve placing the stone in moonlight or using sage smoke to purify its energy. However, it is important to note that these methods are based on spiritual beliefs and may not be scientifically proven.
