George Hall's magazine article took a swipe at the Clogau company's claim to have produced gold for royal wedding rings, pointing out, that the original gold provided came from Gwynfynydd, with Princess Marina's ring in the 1930s having come from a small amount from Gwynfynydd, some from Bedd y Coediwr across the valley from Gwynfynydd, and the remainder from Prince Edward mine, nearer Trawsfynydd. He reminded people also that the kilogram bar presented to the royal family in 1983 which has provided more recent rings came from Gwynfynydd when he reopened it for Sir Mark Wienberg. His final comment was that as far as he knew, Clogau had never produced any Welsh gold for the wedding rings.
