Arizona Blue Turquoise Slab Natural Loose 23X20X18mm Mineral Crafting Jewelry. The image shows a polished piece of blue turquoise, likely from Arizona, characterized by its light blue color and dark veining. Arizona is well-known for its turquoise mines, including the Kingman Mine, which produces stones with a range of colors and matrix patterns. Turquoise is valued as a gemstone and is often used in jewelry and decorative objects. It is considered a symbol of good fortune and protection. The black veins seen in the stone are matrix, which are remnants of the host rock in which the turquoise formed. This particular piece has been tumbled or polished, giving it a smooth surface and enhancing its color and pattern. Turquoise is a mineral, specifically a hydrous phosphate of copper and aluminum. It is a naturally occurring, inorganic solid with a definite chemical composition. While turquoise can be found in rocks and is often part of rock formations, the term "rock" refers to a broader category of naturally occurring solid aggregates of minerals.
