The underlying value of a precious metal is determined by its rarity and the unique demand for utilizing the metal. The price of precious metals fluctuates depending on public sentiment; for example, the price of silver surged in April 2011, because when investors are uncertain about the economy, they turn to assets perceived as safest. Investors can purchase precious metals through precious metals dealers and through exchange-traded funds.
