OM D'EON  is a contemporary jewellery brand based in Portugal since 2014.

The chosen name OM D'EON translates to resonance of eternity, serving as a tribute statement to ancient crystals which we have the honor of working with.

The conceptual design is based in different realms of object categorisation: beauty, decoration, symbolism and function. This minimalist dual-use jewellery is both an expression of one's identity as it is of utility

Most crystals are used in their original morphology, preserving the highest molecular frequency which optimises the performance of transmuting the electromagnetic fields and adds the attribute of exclusivity to the piece. 

The combination of an architecture background and a strong attraction to mineral species was the starting point for the first collection. 

All pieces are designed and handmade at OM D'EON studio in Lisbon.

As a brand, our mission is to create personal objects that blend Art & Science with the final purpose of serving the wearer's highest intentions.
