D-25-kuarsaITS–Smoky Quartz is a precious metal that results from hexagonal minerals forming silicondioxide (SiO2). Such a mineral is also called amorphous quartz or cryptocrystalline because it occurs either in transparent hexagonal crystals or in crystalline. Having a natural pigmentation, smoky quartz has a light brown color.

Quartz is the commonest gangue mineral of ore deposits, and forms the major proportion of most sands and has a widespread distribution in igneous (especially granitic), metamorphic, and sedimentary rocks.

It has a vitreous to greasy luster, a conchoidal fracture, an absence of cleavage, a hardness of 7 on the Mohsscale, and imperme ability relative of 2.65. Quartz is important because it has electrical traits such as Piro and Pizo, and it can conduct ultraviolet rays.

The distribution of silicon dioxide in Indonesia is widespread throughout the country as a result of the number of volcanoes. Some locations for this mineral are along the west coast of Sumatera, south coast of West Java, East Java, West Kalimantan, South Kalimantan (Martapura), South Sulawesi (Maliki) and so on.
