In this article, we explore the geological properties of turquoise, its historical and cultural associations, and its enduring place in the world of birthstone jewelry.
Introduction
Turquoise is more than just a gemstone—it is a symbol of protection, wisdom, and spiritual connection. Its name comes from the French word turquoise, meaning "Turkish," as the gem was historically brought to Europe through Turkey. This December birthstone is also the traditional gemstone for the 11th wedding anniversary, adding to its significance in personal and cultural traditions.
The following sections will delve into the geological formation of turquoise, its sources around the world, its historical use in different cultures, and its symbolic and metaphysical meanings. We will also cover how to care for turquoise jewelry and its role in modern birthstone traditions.
History and Lore
Turquoise has a long and storied history, with its use dating back thousands of years. In ancient Egypt, it was highly prized and used in jewelry, amulets, and even in the funerary mask of Pharaoh Tutankhamun. The Egyptians believed that turquoise had protective powers and used it to ward off evil and bring good fortune.
The gemstone also played a significant role in Native American cultures. The Apache tribe believed that turquoise could be found at the end of a rainbow, and they also thought that attaching the stone to a bow or firearm would improve a hunter’s aim. The Pueblo people believed that turquoise got its color from the sky, while the Hopi tribe associated it with lizards scurrying over the earth. These diverse beliefs highlight the stone’s spiritual and symbolic importance in indigenous traditions.
In Europe, turquoise has been associated with love and remembrance. The tradition of giving a turquoise ring as a symbol of "forget me not" dates back centuries. The gem also became popular among royalty in the 20th century, with Wallis Simpson, the Duchess of Windsor, wearing a famous amethyst and turquoise necklace designed by Cartier. This association with European nobility further cemented turquoise’s status as a gemstone of elegance and prestige.
Geological Formation and Sources
Turquoise is a hydrated phosphate of aluminum and copper. Its chemical formula is CuAl₆(PO₄)₄(OH)₈·4H₂O. The presence of copper gives turquoise its characteristic blue color, while iron imparts green tones. The intensity of the color can vary depending on the ratio of these elements and the presence of other minerals in the surrounding rock.
Turquoise forms in the oxidized zones of copper deposits, typically in arid regions. It is often found in association with other minerals such as quartz, calcite, and limonite. The stone is relatively soft, with a hardness of 5 to 6 on the Mohs scale. This makes it more susceptible to scratches and damage compared to other gemstones like diamond or sapphire.
Historically, one of the most important sources of turquoise was the Nishapur district of Iran, where it has been mined for over a thousand years. The turquoise from this region is known for its intense blue color and is often referred to as "Persian blue." Today, the term "Persian blue" is used to describe any turquoise of that color, regardless of its origin.
In the United States, turquoise is found in states like Arizona, New Mexico, and Nevada. These deposits have produced some of the most famous turquoise in the world, often featuring distinctive matrix patterns that add to the stone’s beauty. The matrix consists of the surrounding rock material that is left in the turquoise, creating intricate patterns that are unique to each piece.
Other notable sources of turquoise include China, Australia, and Mexico. Each region produces turquoise with its own color variations and matrix characteristics. The demand for turquoise has led to the development of various treatments, such as dyeing and stabilization with resins, to enhance the color and durability of the stone.
Symbolism and Metaphysical Beliefs
Throughout history, turquoise has been associated with a wide range of symbolic and metaphysical properties. In ancient times, it was believed to have protective powers and was used in amulets and talismans. The stone was also thought to bring good fortune, enhance wisdom, and promote spiritual growth.
In Tibet, turquoise is considered a national treasure and is believed to grant health, good fortune, and protection from evil. It is often used in religious artifacts and is worn as a symbol of spiritual connection. The gem is also associated with peace and calm, making it a popular choice for meditation and healing practices.
Modern metaphysical beliefs continue to attribute positive qualities to turquoise. It is believed to promote communication, self-expression, and emotional healing. Some practitioners use turquoise to open the throat chakra, enhancing the ability to speak one’s truth and express emotions freely.
Despite these beliefs, it is important to note that metaphysical properties are not scientifically proven. The significance of turquoise in these contexts is largely cultural and symbolic. However, its enduring popularity in jewelry and personal adornment speaks to its lasting appeal.
Care and Cleaning
Due to its relatively low hardness and porous nature, turquoise requires special care to maintain its beauty and longevity. Exposure to harsh chemicals, excessive heat, and prolonged sunlight can cause the stone to fade or become discolored. It is also susceptible to damage from oils and acids, which can affect its appearance.
When cleaning turquoise jewelry, it is best to use a soft cloth and mild soap with warm water. Avoid using ultrasonic cleaners or steam cleaners, as these can cause the stone to crack or lose its color. After cleaning, gently pat the stone dry with a soft cloth.
To protect turquoise jewelry, store it in a cool, dry place away from direct sunlight and other gemstones that might scratch it. It is also advisable to remove turquoise jewelry before engaging in activities that involve physical contact or exposure to chemicals, such as swimming or using household cleaners.
If turquoise is treated or stabilized with resins, it may be more fragile and require even more careful handling. It is always a good idea to consult with a professional jeweler or gemologist when caring for turquoise, especially if it is an heirloom or valuable piece.

Turquoise is a gemstone with a rich history, cultural significance, and enduring appeal. As the December birthstone, it represents a connection to the past and a symbol of protection, wisdom, and spiritual connection.
