When we were young, most of us had one group of women that we looked up to when it came to royalty: the Disney Princesses. These women stood in the face of adversity, defended what they felt was right, righted any wrongs (usually wrongs they caused, but we digress), and looked amazing while doing it. Many of our princesses kept their crowns in the vault for special occasions only, but Jasmine from "Aladdin" kept her crown on throughout the film, helping Aladdin whenever she desired.
Let's say you become a queen, through magic, marriage, or what have you. What kind of land would you want to rule? Will the people there be happy with your ruling or will they get nervous every time you open your mouth? Will your country be a political powerhouse or will it be more subtle in its representation to the world? A lot of these perceptions will lie in you: after all, you're the face of the country to the rest of the world. As a diplomat for your country to the world, your appearance will be surprisingly important.
When it comes to a queen's accessories, the crown is one of the most important things they can use to say about their country. Do you want to have it be more subtle with only a few gems to say that material things aren't as important to your country than others or do you want it to blind people with the amount of bling you have on it? It's up to you! Let's see what side of the spectrum you fall, your majesty!
