Gold futures on the COMEX division of the New York Mercantile Exchange rallied on Tuesday, sending gold prices to a new high, after the US Federal Reserve said it will keep interest rates low "at least through mid-2013," which lowers the opportunity cost for gold investors.

The most active gold contract for December delivery added $29.80, or 1.7 percent, to $1,743 per ounce, the highest closing in history.

Here are some unexpected things made of gold:
