Bejeweled headwear is a term used to describe a type of headwear that is adorned with jewels. The two most common types of bejeweled headwear are tiaras and TIARA, which both have five and six letters respectively. Tiaras are traditionally worn by royalty and are often made of precious metals and decorated with diamonds, rubies, and other gemstones. TIARA is a more general term for any type of headpiece that is adorned with jewels. Both tiaras and TIARA can be worn for special occasions such as weddings or proms.
