Beauty pageant crowns are typically made of tiaras, which are 6-letter headpieces made of precious metals and jewels. Tiaras are usually worn by royalty or those of high social status, but they are also used in beauty pageants to signify the winner. The tiaras used in beauty pageants are often decorated with rhinestones, crystals, and other sparkly materials. They are a symbol of beauty and success for the pageant winner.
