Why Princess Eugenie's wedding ring will be exactly like Meghan and Kate's

Princess Eugenie will soon tie the knot with fiancé Jack Brooksbank in the second royal wedding of the year.

Like Meghan Markle before her, Princess Eugenie's wedding ring will be crafted in the same Welsh gold used all members of the Royal Family for nearly 100 years.

All royal brides wear wedding bands from a lump of gold taken from the Clogau St David mine in Wales.

Kate Middleton wears her band of yellow Welsh gold alongside her sapphire and diamond engagement ring, set in 18 karat white gold and made by jewellery house Garrard. It was originally owned by Princess Diana.

The Duchess of Cambridge chose to have her wedding band crafted by Welsh jewellers Wartski, while the Duchess of Sussex went with London-based Cleave and Company.

With 19 fine jewellery companies holding a Royal Warrant, Princess Eugenie has plenty of options as to who will turn her piece of Welsh gold into a wedding ring. She'll wear the band alongside her pink padparadscha sapphire engagement ring.

The same lump of Welsh gold from the Clogau St David mine has been used to make wedding bands for the royal family since 1923.

However, due to a halt of gold mining in Wales, supplies are running low, meaning the metal is now more precious than ever.

"With no gold mining taking place in Wales today, Welsh gold supplies may eventually run out, making it possibly the rarest gold in the world," Ben Roberts, the managing director of Clogau, told the Evening Standard.

"On November 28, 2017, 10 lots of Clogau gold, mined under government lease between 1979 and 1981, were expected to fetch about £9,000 ($15,000 AUD) at auction."

But the lots went on to sell for far more than expected, fetching $77,000 AUD.

Thankfully, the mine gifted Queen Elizabeth with another lump of the gold for her 60^th birthday so supplies aren’t expected to run out for the Royal Family just yet.
