Turquoise is an opaque mineral that occurs in beautiful shades of blue, bluish green, green, and yellowish green. It has been treasured as a gemstone for thousands of years. Isolated from one another, the ancient people of Africa, Asia, South America and North America independently made turquoise one of their preferred materials for producing gemstones, inlay, and small sculptures. It is a secondary mineral deposited from circulating waters, and it occurs chiefly in arid environments as blue to greenish, waxy veinlets in alumina-rich, weathered, volcanic, or sedimentary rocks.
Chemically, turquoise is a hydrous phosphate of copper and aluminum (CuAl6 (PO4)4 (OH)8·4H2O). Its only important use is in the manufacture of jewelry and ornamental objects. However, in that use it is extremely popular - so popular that the English language uses the word \"turquoise\" as the name of a slightly greenish blue color that is typical for high-quality turquoise. Very few minerals have a color that is so well known, so characteristic, and so impressive that the name of the mineral becomes so commonly used. Only three other minerals - gold, silver, and copper - have a color that is used more often in common language than turquoise.
Turquoise is a hydrous phosphate mineral that belongs to the family of phosphates, specifically the copper-aluminum phosphate mineral group. Its chemical formula is CuAl₆(PO₄)₄(OH)₈·4H₂O.

Chrysocolla, variscite, amazonite, howlite, and African turquoise are notable alternatives to genuine turquoise, each exhibiting vibrant blue and green hues. Chrysocolla is a hydrated copper silicate mineral often found alongside turquoise deposits and is prized for its intricate patterns. Variscite, a phosphate mineral, can be mistaken for turquoise due to its similar color range. Amazonite, a feldspar mineral, displays a soothing blue-green color reminiscent of turquoise. Howlite is frequently dyed to mimic turquoise"s appearance and serves as an affordable substitute in jewelry. African turquoise, while not true turquoise but rather a type of jasper or chalcedony, has gained popularity for its unique beauty. Dyed howlite and magnesite are commonly used in mass-produced jewelry but can mislead buyers into thinking they are purchasing genuine turquoise. The market has seen confusion due to these dyed stones, leading some consumers to avoid authentic turquoise altogether.
Understanding the geological formation of these minerals reveals that many share similar elements like copper and aluminum that contribute to their colors. Hydrothermal alteration processes also play a role in creating minerals with comparable properties to turquoise. Buyers should exercise caution when selecting stones that appear too uniform in color, as they may not be genuine. "

Turquoise formation is primarily linked to hydrothermal activity, where mineral-rich fluids circulate through the Earth"s crust. These fluids, rich in copper, aluminum, and phosphates, interact with host rocks like igneous and sedimentary types. The chemical reactions between the dissolved minerals and surrounding rock materials lead to the deposition of turquoise within fractures or cavities. The presence of copper is essential for turquoise"s formation, as it combines with other elements to create the mineral. Over time, geological processes such as weathering can alter its appearance and color, resulting in characteristic blue and green hues. Turquoise typically forms in arid climates and is found in regions like the southwestern United States, China, Egypt, Iran, and Mexico. Notably, the most exquisite turquoise comes from northern Iran due to its unique geological conditions. The stone often appears as an aggregate of microcrystals rather than well-formed crystals, leading to a lower porosity and higher durability.
The matrix pattern within turquoise stones varies based on the host rock material and can create unique designs. Turquoise deposits are often associated with specific geological structures that facilitate hydrothermal fluid movement, enhancing mineralization chances. Overall, understanding these processes provides valuable insights into turquoise"s formation and distribution across various regions. "
