When it comes to jewelry, royals don't play around. And when you have heirloom pieces that include Cartier tiaras and sapphire rings, who wouldn't want to accessorize their outfit with an item that represents years of family history? From duchesses to princesses, gorgeous gems have been worn for special occasions such as weddings, galas, and even red carpet premieres. 

But that doesn't mean being decked out in diamonds doesn't come without rules. According to Grant Harrold, a royal etiquette expert in the U.K., members of the British monarchy like Meghan Markle, Kate Middleton, and Princess Eugenie have to follow strict rules when it comes to their dazzling accessories, like how they can't wear their tiaras before 6 p.m. Though events such as their weddings are one exception to the rule. Oh, and did you know tiaras are reserved for married women?

From Princess Diana's iconic Spencer tiara to Meghan Markle's bespoke engagement ring and Queen Letizia of Spain's mesmerizing headpieces, you won't want to miss this roundup of royal jewels.
