Brief.

CITREA is a sculptural floor lamp with a rough, stone-like body split by an irregular vertical crack, and amber light comes out of it.

Concept and name

CITREA is a sculptural floor lamp inspired by fractured rock. Light comes out of a broken, monolithic form and reads as atmosphere before it reads as function.

The name comes from citrine, the golden gemstone known for its warmth and light. The dark textured surface against warm amber is meant to feel intimate, with a bit of tension.

Inspiration board. Broken rock and a golden stone.

Fractured rock, amber light, citrine crystals and three colour swatches.

Inspiration board: fractured rock, amber light, citrine crystals and warm interiors

What the board collects

The board gathers fractured rock formations, volcanic textures, geological erosion and warm interiors, plus citrine crystals and a palette of three swatches.

Idea sketches. Five pages in blue pen.

Five pages of preliminary sketches, one sheet each, before a concept was picked.

Preliminary sketches

The first page hangs a looping lamp over a dining table, with notes on transparent 3D filament, PVC tube and hidden cables. The next pages test other forms and ways of letting the light out.

Final concept. A cylinder with a glowing crack.

One sheet fixes the form, the parts and the details.

From loose ideas to one drawing

The final sketch is a standing cylinder with a crack down one side. It splits the lamp into three shell parts, a base and a light source, and shows the cable running to the wall outlet.
