THE OXYGEN COLLECTION

The Oxygen Collection explores connection, movement and the precision of construction. Designed in Copenhagen by architect and founder Sarah Emilie Müllertz, the collection takes inspiration from Japanese joinery, where individual elements are carefully constructed to connect without compromising the clarity of the overall form. 

Like the air we breathe, each link flows into the next, creating jewellery that comes to life through movement. The apparent simplicity of the forms conceals a technically complex construction, reflecting KINRADEN’s architectural approach to jewellery, where structure and function become an integral part of the expression.

The collection is crafted in recycled 18K gold and recycled sterling silver, with selected pieces bringing the two precious metals together within a single construction. Across rings, earrings, bracelets and necklaces, repeated links create rhythm and continuity around the body. The collection currently spans gold, silver and mixed-metal designs. 

The BREEZE Ring distils this idea into four interconnected links, drawing directly on the precision and logic of Japanese joinery. The BLAST Bracelet extends the structure around the wrist, while INHALING HIM and EXHALING HER explore connection through articulated forms that respond naturally to movement. THE GASP and THE SIGH Earrings translate the same language into smaller sculptural compositions. 

Throughout Oxygen, construction is not hidden but made visible. Links, joints and connections become defining elements of the jewellery, bringing together engineering precision and sculptural form.
