Two of a kind

A timeless classic reinterpreted by the Maison, the Toi & Moi ring embodies two stones that, while distinct, are in perfect harmony. They meet, intertwine, and merge in a perfect balance of uniqueness and unity. Each piece is an invitation to write your own story, celebrating both connection and self-expression.
