3. State Diadem of George IV

Wearer: Elizabeth II, the Queen Since 1821, the owner Value Estimate: $600,000 The George IV State Diadem is one of those items that simply gets better with age. The amazing headdress was custom-made for King George IV's coronation in 1821. More than 1,333 diamonds are put into the diadem's base, which is encircled by two strings of pearls. As such, it weighs a ton.

Even though Her Majesty would rather not wear it the other 364 days of the year, Liz still makes use of it when she dusts it off for the yearly State Opening of Parliament.

4. Grand Duchess Vladimir Tiara

Wearer: Elizabeth II, the Queen Since 1921, the owner Value Estimate: $470,000 The Grand Duchess Vladimir Tiara was not at all created by the English. Actually, Grand Duchess Elena Vladimirovna was the owner of it before she was able to secretly remove the diadem from Russia during the revolution. In 1921, the Duchess sold the tiara to Queen Mary.

That puts its current value above $470,000 after accounting for inflation, but that is only a starting point. It's probably far more valuable than that because of its fascinating history.
