Our jewelry is made of 925 sterling silver and recycled bronze with double plating of 18 and 24 carat gold. Each design is hand-finished to ensure its durability and comfort.

Our pieces are made with high-quality gold plating and vermeil, giving them a luminous finish. We do not currently offer solid gold designs.

With proper care, your pieces will retain their beauty. Gold plating naturally wears over time, while sterling silver may develop a soft patina.

Avoid contact with water, chemicals, and abrasive products. Clean them carefully with a soft cloth and store each piece in its pouch or box when not in use.

We recommend removing your jewelry before showering, swimming or washing your hands to prolong the finish and prevent tarnishing.

At the moment, we do not offer sizing services, but we do offer professional cleaning and minor repair services. Please contact our team for more information.
