Queen Elizabeth's Wedding Ring Has a Secret Engraving & Three People Know What It Is!

A new book, “Prince Philip: A Portrait of the Duke of Edinburgh,” has been released and features a fun fact about Queen Elizabeth‘s wedding ring that we never knew before.

“At least [Prince] Philip didn’t have the expense of a wedding ring, as the people of Wales supplied a nugget of Welsh gold from which the ring is made,” the book reads (via People). “She never takes it off and inside the ring is an inscription. No one knows what it says, other than the engraver, the Queen and her husband.”

You can check out some photos of Queen Elizabeth‘s wedding ring in the gallery of this post.
