CORE Honeycomb — Lume Pendant
Structured geometry. Integrated light.
The CORE Honeycomb Lume Pendant is precision-machined from solid forged carbon fiber and defined by a deep hexagonal structure inspired by engineered form.
By day, it remains restrained — matte black carbon with dimensional depth. By night, the engraved honeycomb channels emit a controlled glow when charged by sunlight or UV.
Each channel is filled with high-performance strontium aluminate luminous compound, integrated directly into the structure — not surface paint or coating.
Every pendant is carved and finished entirely in-house. The natural forged carbon marbling ensures each piece is one-of-one.
Architectural depth. Controlled illumination. Engineered clarity.
Glow Options
Green — high-visibility output with long duration
Aqua — cooler tone with refined contrast

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.
