The prince is set to exchange vows with his fiancée Meghan Markle on May 19, so he has until then to decide, but the groom-to-be may opt out of wearing a band. A number of married male royals in his family have chosen not to, including his older brother William and his grandfather Prince Philip.
The reason is simple: it's all a matter of taste.
William doesn't like to wear jewelry of any kind, and so decided to remain ringless following his marriage to Kate in 2011. His decision was announced shortly before their Westminster Abbey wedding ceremony, with a statement from St James' Palace confirming the news. "It was something the couple discussed but Prince William isn't one for jewelry – he doesn't even wear a signet ring – and decided he didn't want to," an aide said, explaining: "It really is just down to personal preference. Catherine will wear a ring fashioned from a lump of Welsh gold owned by the Royal Family that has been smelted down."
Despite being married to the Queen for nearly 70 years, Prince Philip has also never worn a wedding ring. William's father Prince Charles, meanwhile, does wear one, next to a signet ring on the little finger of his left hand.
Harry, however, may choose to wear a wedding ring as a symbol of his love for Meghan. Since meeting his soulmate, the romantic prince has continued to wear a beaded blue, white and black "love bracelet" that he is believed to have bought with Meghan or received from her; his fiancée also has a matching bracelet.
Royal watchers will have to wait until the big day to see Harry and Meghan's wedding bands. In keeping with tradition, the couple will likely use pure Welsh gold to create their rings. It is a near 100-year-old tradition that the royals have followed; the gold in question is particularly rare and originates from the Clogau St. David Gold Mine in Dolgellau, Wales, which is no longer in operation.
Members of the royal family have used the gold to create their weddings bands since the Queen Mother married the Duke of York on April 26, 1923.
