“Crown jewels” is a term that refers to all the jeweled finery owned by royalty. It includes their crowns, but it can also consist of royal robes, scepters, and jewelry collections. Some regal items are only worn at special ceremonies and others are used any time they wish to dress up.
When many people refer to the “Crown Jewels,” they are often talking specifically about the British crown jewels.
Many items belong in a country’s crown jewels: from scepters and orbs to robes and mantles, from gems and jewels to actual crowns. Royal regalia are rich in history and value.
