Fabergé Easter Eggs are ornaments covered in gold, silver, diamonds, and jewels. Fifty of these original eggs were made for the Russian royal Romanov family between 1885 and 1917 after Czar Alexander III wanted an extravagant gift for his wife. Today, seven eggs remain missing and could be anywhere in the world. One egg, which was covered in sapphires and diamonds, was sold at a flea market in the United States in 2010 for just over $13,000, even though it's actually worth over $30 million (the dealer valued it incorrectly)!
