noble metal
Gold or platinum
A noble metal resists corrosion and oxidation, remaining chemically stable under ordinary conditions.
Gold, platinum, and silver are the classic examples—they don't rust or tarnish readily.
The term contrasts with base metals like iron or copper.
In chemistry and jewelry, nobility indicates durability and resistance to chemical attack: Gold's status as a noble metal makes it ideal for heirloom pieces.
