Zinc is a shiny, naturally-occuring, bluish-white metal that is often used as an alloy for jewelry. It is rarely used in its pure form. Brass is the most common zinc alloy, but it is also a component of the nickel-copper alloy known as nickel silver. It is lead free, versatile and low cost so it is frequently used in jewelry components. Zinc alloy is also sometimes referred to as Tibetan silver.
