There was a lot of jewels, tiaras, and brooches left by Queen Elizabeth.
The items will be displayed at the Tower of London.
The new Princess of Wales is expected to be passed down to King Charles and his family.
Upon the death of his mother, Queen Elizabeth II, King Charles III likely acquired her extensive jewelry collection.
The Crown Jewels are a collection of royal ceremonial objects on display at the Tower of London. The Queen's private collection is worth millions of dollars and consists of family heirlooms, gifts, and items purchased by the monarch herself.
Josh Rom told the New York Post that she would probably want to pass on items from her private collection. The majority of the collection will go to Charles and then Kate, so they may not be left much in the will.
The royal collection began when Queen Victoria began collecting jewels as the British empire expanded. During the reign of Queen Mary, the collection continued to grow due to her connections with jewelers and world leaders.
Queen Mary gave many of her jewels to Queen Elizabeth II, who then lent them out. The tiara was worn by Kate at her wedding. The New York Post reported that the bride wore a diamond bandeau during her wedding.
If the crowns were left in the Queen's will, the recipients would have to pay a 40% inheritance tax, according to the Post.
He said it would be best for the family to leave the items in the royal collection.
