AguaDeOro

AguaDeOro is based in Zurich, with a second shop in Geneva, and works in 18-carat Fairtrade gold across several colour tones as well as 950 platinum. The range runs from solitaire, trilogy, pavé, and halo engagement rings to wedding bands with or without diamonds, and the studio also makes earrings, necklaces, and bracelets under named collections. Nothing is mass-produced. Each piece is designed with the customer and then made in a Swiss workshop, so the route from sketch to finished ring stays short.

Beyond new commissions, the studio handles resizing, cleaning, polishing, and engraving, and it offers white, coloured, and lab-grown diamonds along with other gemstones for couples who want a particular look. A three-year warranty comes as standard, with a lifetime option available on request.
