Turquoise is not one of the main minerals such as iron, copper, silver, etc. of the basic elements, instead it is one of the secondary elements that were formed over time as a result of minerals that accumulate on the crust of the planet through two processes They are the process of weathering and oxidation . Usually turquoise stone is formed as a crust in cracks or as veins , or as a solid mass . As the water moves through the porous rock, minerals dissolve, such as copper, aluminum, and iron. These minerals often come from other minor elements; For example: copper may come from the mineral azurite. Over time, these minerals accumulate in pores, cracks, and cavities to form deposits known as turquoise stones. Oxidation of other minerals present also contribute to the formation of this stone.
The color of turquoise can vary depending on the amount of iron and other minerals present. Since turquoise formed in the rocks, it is often veined with other minerals to form a beautiful mineral mold. Most turquoises form in a drier climate. It often forms in rock formations that arose from volcanic activity. It is such formations that lead to the formation of turquoise because they have high levels of iron oxides.
in addition to; The process of forming turquoise stone differs from one region to another, so that it varies from one location to another in the same region, which led to the emergence of unique forms of turquoise stone. For this reason, turquoise stones do not get their name immediately after their extraction, because they need a period of time to name them after verifying what they are and that they belong to turquoise. For example: the “Sleeping Beauty” turquoise stone is extracted from the “Sleeping Beauty” mine near Globe, Arizona.
chemically; The mineral turquoise is a basic water phosphate of copper and aluminum. It forms when chemical water drips through the host stone for centuries, leaving turquoise deposits behind. For the sweaty turquoise; It is deposited in cracks and open voids caused by small faults or other movement of rocks. It may or may not have a matrix pattern, but most turquoises are primarily vein shaped. These range from very thin outer layers less than 1/965 an inch thick to very wide veins of 5 inches or more. In terms of thickness. And the formation of wide veins tends to be more porous than low-grade turquoise. The delicate pieces of veined turquoise are difficult to cut on their own, so they are cut in two ways. Either they are backed with man-made materials such as epoxy or hard plastic, or they are left with a stiff tissue material between cells that sticks to that thin piece and they are cut into a single piece. In both cases; The backing method strengthens the stone, making it less likely to break and easier to cut. Without the use of a thicker form of support, these thinner pieces will be unusable. Sometimes turquoise stones are formed by surrounding them and mixing with the broken parts of the rocks, and this is called turquoise breccia. Another popular form of turquoise gemstone is its formation as a single nugget. These blocks consist of assemblies of turquoise pieces in the holes that are filled with mud.
The relationship between the colors of the turquoise stone And the process of formation 965
The colors of the turquoise stone cover a much wider range than is believed Most people. The colors vary and in fact vary greatly in different locations of the same mine from which the turquoise stones are mined. If the copper element is the most concentrated element in the turquoise mixture, the stone will be colored blue, while the iron element will add shades of green. But if the percentage of aluminum is more than the normal percentage, in this case the stone will acquire a degree from green to white. The addition of zinc produces a greenish-yellow color, in addition, it increases the hardness of the stone. Turquoise stones come from Nevada in shades of blue and green to blue and vice versa beside green, and all of these shades are popular with people. Nevada turquoise also produces some unique shades of bright mint to apple to neon yellow green that are unmatched anywhere else on earth. Large amounts of zinc and iron are the reason for the beautiful, bright green to yellowish green tones. Large quantities of greenish-yellow turquoise were found in Lander County. In some cases, stones from one mine are so similar to stones from other mines that even a gemologist can hardly tell the difference between them. No one can say that the stones extracted from the same mine have the same color as there is always difference, but in general the greater part of these stones share some common characteristics and characteristics.
