Being a part of the royal family comes with a ton of protocol that must be followed. Meghan Markle, being from the United States, has had to learn all of the rules at breakneck speed. According to royal etiquette expert Myka Meier, "there's allegedly a daytime diamond ban. Meaning royals can't break out their fanciest jewelry before 6 PM." The royal rule was put into place as to not seem too flashy in public, however, you will catch the royal ladies wearing pearls, sapphires, gemstone, and metallics before 6 PM. If you're Meghan Markle, you will wear toned-down versions of diamond jewelry, she's such a rule-breaker!
