Natural mineral stone bracelet

Minerals (from the medieval Latin mineral, derived from the old French mining, "mine") are inorganic and natural bodies, with a well-defined or variable chemical composition within a narrow range; ils make up the earth's crust and other celestial bodies. Ils are all solids (except native mercury). Ils have constant physical and chemical properties, which allow them to be identified and distinguished from each other. In the historical context, the expression mineral kingdom referred to all inanimate objects, mainly minerals and rocks, according to Systema Naturae by Linnaeus.

Today's term, properly understood in a scientific sense, is more restrictive and refers to chemical compounds of natural origin, that is, bodies which have a definite or variable chemical composition within very precise limits imposed by stoichiometry; ils are almost always in crystalline form, are solid at room temperature (except native mercury and ice), and mostly inorganic.
