The most valuable of all precious metals is rhodium. This silver-colored metal is extremely rare and is commonly used for its reflecting properties. A long-time favorite of precious metals investors, gold has been used as a store of value for thousands of years. Gold is known as an investment that tends to maintain its value well during economic downturns and that can overcome major recessions quite well.
Gold is also an excellent hedge during periods of high inflation compared to cash investments. While gold is a big investment, the cost of buying significant amounts of gold can be a bit prohibitive for some newer investors.
