This ring is beautifully crafted in rare Welsh 9ct yellow and rose gold and makes the perfect addition to any jewellery collection. The Clogau brand was first brought to life when a local Welshman named William Roberts made an exciting discovery in the rural mountains of Snowdonia. Roberts was able to extract a stockpile of rare Welsh gold that was then used exclusively to create the jewellery that founded the Clogau brand. Since then, Clogau jewellery has become renowned around the world not just for their striking designs but for being worn by members of the Royal family including Her Majesty the Queen and the late Princess Diana of Wales. All of our Clogau jewellery is delivered in elegant Clogau packaging. 9ct Yellow and Rose Gold, Shank Thickness: 1.1mm, Weight; 5.13g
