The name “quartz” was introduced by Georgius Agricola (1494/1555) in 1529, a 16th century scholar considered the father of mineralogy.
Smoky quartz is one of the colored variants of mineral quartz, it is a macrocrystalline quartz, which owes its color to the natural or artificial irradiation of the aluminum salts it contains and its color can vary from brown to black.
Very pretty fine stone that can be mounted in jewelry.
