Unique jewellery with Welsh gold
Nestled deep within the mountains of Snowdonia is a treasure trove of the world's rarest and most sought-after gold - Welsh gold from the Clogau St. David's gold mine.
A touch of this Welsh gold, as used by Royalty for over 100 years, goes into every Clogau item.

Since 1911 the mine has been re-opened several times for smaller-scale operations. It last closed in 1998. In 1999 the mine was taken over and held by a local exploration company.
In November 2010 the mine was acquired by a new exploration company, Midas Exploration, who hope to restore the mine to production.
So it is not even open to produce any gold!!!!
