Turquoise is a fascinating mineral that has captivated people for thousands of years. It is a blue-green colour that is often associated with the sky and the ocean. Turquoise has been used for ornamental and decorative purposes since ancient times and it remains a popular gemstone today.
The Chemical Properties of Turquoise.
Turquoise is a hydrated phosphate of copper and aluminium. Its chemical formula is CuAl6(PO4)4(OH)8·4H2O, which means it contains copper, aluminium, phosphorus, oxygen and water. The water in turquoise is what gives it its distinctive colour. The exact shade of turquoise can vary from pale blue-green to deep greenish-blue, depending on the amount of copper in the mineral. Turquoise can also contain other minerals such as iron and zinc which can affect its colour.
Where is Turquoise Found?
Turquoise is found in many parts of the world including Iran, the United States, China, Mexico and Egypt. The finest turquoise comes from Iran where it has been mined for over 5,000 years. In the United States, turquoise is found primarily in the Southwest where it has been a significant part of Native American culture for centuries. In Mexico, turquoise is often found in association with silver and it has been used to make jewellery and other decorative items since pre-Columbian times.
Turquoise is formed in arid regions, where groundwater containing copper and aluminium seeps through rocks and forms veins. Over time, these veins can solidify and form the turquoise mineral. Turquoise can be found in a variety of host rocks including shale, limestone and sandstone. The host rock can affect the colour and quality of the turquoise.
Turquoise Has Many Purposes.
Turquoise has been used for many purposes throughout history. In ancient Egypt, it was used to make jewellery and it was also used in burial ceremonies to protect the deceased from harm. In Persia, turquoise was used to make tiles and mosaics, and it was also used in the construction of mosques and other buildings. In the Americas, turquoise was used by Native American tribes for ornamental and ceremonial purposes.
Today, turquoise remains a popular gemstone. It is often used to make jewellery such as rings, necklaces and earrings. Turquoise is also used in home decor such as vases and decorative bowls. Turquoise is valued for its unique colour, as well as its rarity and durability. However, because of its popularity, there is a significant amount of synthetic turquoise on the market. Synthetic turquoise is made by adding dyes and resins to other minerals, such as howlite or magnesite, to create a material that looks like turquoise.
In addition to its decorative uses, turquoise has also been studied for its potential health benefits. In traditional medicine, turquoise was believed to have healing properties and was used to treat a variety of ailments. Today, researchers are studying the potential anti-inflammatory and anti-cancer properties of turquoise. Some studies have suggested that the copper in turquoise may have anti-inflammatory effects while other studies have found that turquoise may have anti-cancer properties.
