Valuable metals are some of the most sought-after investments in the world. Rare, beautiful and timeless, these inconspicuous elements on the period table are worth quite a bit to your wallet. Take gold for example—one metric ton of it is so dense it could be contained in 37 cubic centimeters and be worth more than $12 million.

Today, platinum is considered the crème de la crème of precious metals, worth a whopping $1,620 an ounce.
