While celebrities tend to go for lavish weddings, topped off with rings adorned with diamonds to rival the bling of their engagement rings, British royals – from the Duchess of Cambridge to the Duchess of Sussex – normally opt for more understated traditions . They may have their pick of ancient chapels and rituals, but for nearly 100 years Britain’s senior royals have worn plain yellow gold wedding rings, made from regal metal derived from Wales – the rarest, most expensive in the world, with Welsh gold bullion worth up to five times the spot price.

That same nugget was used to craft wedding bands for Queen Elizabeth, Princess Margaret, Princess Anne and Princess Diana.

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.

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.” View this post on Instagram A post shared by Wartski (@wartski1865) on Jun 8, 2020 at 2:46am PDT 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.

A spokesperson for Cleave says they were asked to produce “a classic 18-carat gold wedding band” for the duchess. The ring appears to be daintily slim, in keeping with Meghan’s apparent fondness for delicate jewellery.

So there could be a new Welsh gold rush on the way which would ensure the royals’ wedding ring tradition continues for some years yet. Want more stories like this? Sign up here .
