King Charles and Queen Camilla are celebrating their 21st wedding anniversary on Thursday, April 9, and although they’re not marking the occasion in Italy like they did for their 20th, the pair will no doubt be enjoying a special day closer to home. The traditional gemstone gift for a 20th anniversary is emeralds, but for a 21st anniversary celebration, a gemstone that’s not quite as well known reigns.
Justin Daughters, managing director at Berganza, tells Marie Claire that “21st anniversaries can be celebrated with the help of iolites, known as 'water sapphires' because of their color that changes from blue to violet.”
