COLLECTION
Maternidade
The collection portrays motherhood as a plural and timeless experience.
Each piece represents a stage of this journey, highlighting unique virtues, challenges, and lessons. Rose quartz, present in all pieces, symbolizes the guiding thread of unconditional love — yet in each phase it is cut differently, just as a woman reinvents and (re)discovers herself in her relationship with herself and her children.
COLLECTION
Transformação
How special do you truly know you are?
The Transformação collection celebrates the changes and discoveries brought by the self-knowledge journey.
The square, a symbol of stability and inner growth, is the shape that guided the design of these pieces made in rose gold, amethysts, and white diamonds.





COLLECTION
Separatio
The Separatio collection celebrates the harmony between mindful self-reflection and the simplicity of living in the present.
Inspired by Jungian psychology, Separatio represents the separation between the conscious and the unconscious — a process of distinguishing light from shadow within each of us.
