A natural turquoise specimen of intense sky-blue color with characteristic zoning, originating from the Zhilandy deposit (Kazakhstan), which is renowned for producing high-quality turquoise.
The specimen is partially polished, retaining elements of its natural surface, which reveals both smooth, glossy areas and naturally textured zones. The structure contains numerous brownish inclusions, presumably composed of goethite, limonite, or other iron-bearing oxides and hydroxides. Additionally, microinclusions of manganese and copper compounds may be present, typical of supergene (secondary) oxidation zones.
