Duna Ring
Duna Ring
Couldn't load pickup availability
The Duna Ring is inspired by the organic shapes of the Murcia desert, where the sand dunes form endless curves in the wind. A timeless, sculptural piece that envelops the finger like a small silver wave.
It belongs to the Pangea collection , born from a fascination with what lies hidden underground: minerals, fossils, and textures created in silence over millions of years. They are hidden treasures, accessible only to those who wish to observe and discover beauty in the invisible. Each piece is a fragment of that subterranean universe, transformed into a handcrafted jewel.

CARE
We handcraft all our pieces in Murcia, which means no two pieces are exactly alike. Each piece has its own personality and, in many cases, textures that are part of its design. We only work with precious metals : 18-karat gold, sterling silver, and 18-karat gold plating. With proper care, your jewelry should last a lifetime.
To keep them in perfect condition, we recommend:
- Sterling silver : With wear, silver stays clean and shiny. However, it's best to remove it when washing your hands and avoid contact with colognes, creams, or chemicals.
- Jewelry with stones : These are delicate pieces; try not to hit them to protect both the stone and the setting.
- Gold-plated jewelry : Remember that gold plating wears off over time. These pieces are designed to be worn with care, avoiding showers, baths, and constant daily use. It's best to keep them protected and wear them on special occasions.
- Storage : Store your jewelry in a dry place, preferably in its original box or in individual bags, avoiding contact with costume jewelry metals that could damage it.
And, of course, you can always contact us to clean and service your pieces . We want your jewelry to continue shining like new.
