inspired by the cobogó | a defining element of brazilian modernist architecture, where repeated openings allow light, air and shadow to move through a structure.

the ring follows the same principle through a continuous rhythm of circular forms. emerald and green tourmaline alternate around the hand, each stone carrying its own depth and variation of green.

how it's made
your piece is built after you order it, not before. each stone is selected individually for its colour, character and relationship to the stones around it, so production typically takes four to six weeks from payment confirmation.

each ring is handcrafted individually in our haarlem studio. you'll receive a note when your order enters production, and again once it's dispatched.

choose your stone
this piece is shown in emerald and green tourmaline, creating subtle shifts in colour across its repeating structure. the design may be realised with your chosen stones, allowing the rhythm and character of the ring to change through material.

Mark where the end meets the loop
Lay it flat and measure it with a ruler in cm or mm
Choose your fit:
- Snug — add 1 to 1.5 cm
- Standard — add 1.5 to 2 cm
- Loose — add 2.5 cm or more

precious metals are made to be worn. with time, their surfaces will naturally change, carrying subtle marks and traces of wear.

clean gently with warm water and a soft cloth, store your piece separately, and keep it away from perfume, creams and household chemicals.

each piece is made in 18ct gold, platinum or argentium silver, chosen for how it holds form, catches light and takes on wear.

no single metal is right for every design, only the one built for yours.
