MATRIX Hex Ring — Forged Carbon
Structured geometry. Defined depth.
The MATRIX Hex Ring is precision-machined from solid forged carbon fiber and defined by a deep honeycomb structure inspired by engineered form.
Each hex element is carved directly into the carbon, creating dimensional shadow and controlled surface texture across the band.
No metal. No coating. No added elements. Only forged carbon shaped through geometry.
Finished entirely in-house, every ring reveals a distinct marble pattern formed during forging. No two pieces are identical.
Architectural structure. Material clarity. Engineered restraint.

How to Measure Your Wrist
- Measure your wrist just above the wrist bone.
- Use a flexible measuring tape. If you don’t have one, use a string and measure it against a ruler.
- Keep it snug — not loose, not tight.
- Do not add extra space. We include a comfort allowance in the bracelet design.
