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.
bracelet size guide
Use the method below to visualise how each bracelet length sits on the wrist. Whether you prefer a close daily fit or a looser, layered feel, this will help you choose.
- Wrap a soft measuring tape, ribbon, or string just below your wrist bone, where your bracelet would naturally rest
- 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
If you are unsure, we are here to help. Send us your wrist length and how you would like it to sit.
ring size guide
all our sizes are eu sizes. the eu size is the inside circumference of the ring in millimetres, the same number our ring sizer shows.
with our ring sizer: slip it over the base of your finger, pull until it sits snug but still slides over the knuckle, and read the number in the window. that number is your size. if you fall between two, choose the larger.
with a ring you own: measure the inside diameter and find the closest match below. an inside diameter of 17.2 mm is size 54.
