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. Platinum, one of the world's rarest metals, is naturally found in the earth's crust, courtesy of shattered meteorites from two billion years ago. Today, platinum is considered the crème de la crème of precious metals, worth a whopping $1,620 an ounce.
