Prince Harry is breaking tradition and will wear a wedding ring.
His will be a platinum band with a textured finish, while his bride, Meghan Markle, will wear a ring fashioned from a piece of Welsh gold given to the couple by the Queen.
Both rings, crafted by Cleave and Company, will be carried to St George's Chapel by best man, Prince William.
Wedding rings worn by royal brides are traditionally made from Welsh gold but very few men in the monarchy have chosen to put on a wedding band.
When the Duke of Cambridge married, he followed in the footsteps of his grandfather the Duke of Edinburgh and uncle the Duke of York, who both chose not to wear the symbol of marriage.
During the Giving of the Rings part of the ceremony in St George's Chapel, Harry and Markle will exchange bands after hearing the Archbishop of Canterbury describe the jewellery as "a symbol of unending love and faithfulness" and a reminder of their vows.
Markle first receives her ring from Harry, who will say: "Meghan, I give you this ring as a sign of our marriage.
"With my body I honour you, all that I am I give to you, and all that I have I share with you, within the love of God, Father, Son and Holy Spirit."
When Harry receives his ring from Markle, she will place the band on the fourth finger of his left hand before addressing him with the same words.
