Meghan Markle, Kate Middleton, Princess Diana, Queen Elizabeth – for British royal family wedding rings, only the world’s most expensive gold, from Wales, will do

Diamond wedding rings? Not for us – gold nuggets gifted to the British royal family established a century-long custom for simple wedding bands – in contrast to more showy celebrities
The custom started with the queen mother in 1923 when a nugget of pure gold from the Clogau St David’s mine in North Wales was gifted to the royal family, a piece of which was used to make the then-Lady Elizabeth Bowes-Lyon’s wedding ring for her marriage to the future King George VI. That same nugget was used to craft wedding bands for Queen Elizabeth, Princess Margaret, Princess Anne and Princess Diana.
Handily, in the 1980s the queen was gifted more gold from Wales; 36kg was presented by the Royal British Legion, part of which was used to make Sarah, Duchess of York and, it is thought, Sophie, Countess of Wessex’s wedding rings. A further 1kg was gifted from Gwynfynydd Gold Mine in celebration of the queen’s 60th birthday. This is likely the source of Catherine and Meghan’s wedding rings.
Ahead of the Duke and Duchess of Cambridge’s nuptials, St James’s Palace made the statement: “The wedding ring that Catherine Middleton will wear will be made of Welsh gold. The gold was given to Prince William by the queen shortly after the couple were engaged. It has been in the family's possession for some years and has been in the care of the royal jewellers. There are no further details on which mine the gold was mined from.”
Sitting half-hidden by her huge sapphire engagement ring, Catherine’s slim yellow gold wedding band was made by royal warrant holders, Wartski. Fittingly, the jeweller was founded in North Wales and has a store in St James’, just around the corner from Prince William’s London home at the time.
