Gold is one of the most precious metals, and I love working in all its shades. My gold range keeps growing, in yellow gold, white gold and rose gold, in solid 9ct, 18ct and 22ct, and in some pieces a rich gold plating. There's a shade for every taste. I design every piece, and we make them in our Llandeilo workshop.

In truth, much of my gold work is commissioned, made especially for one person. So if you have something in your mind's eye, I'd love to help you create it. Talk to me about a commission.
