Fashion jewelry refers to any jewelry that is not made from precious metals. Fashion jewelry is sometimes called “costume jewelry,” and costume jewelry in bulk is often made from base metals, such as, brass, copper, or aluminum. Custom fashion jewelry can also be made with textiles or leather, or base metals that are plated with precious metals. If a piece of fashion jewelry is made with a gemstone, it is almost always simulated, which means the “gemstone” might be plastic, glass, or crystal (among others).
