Brass · Spanish alabaster

Exuding the essence of quiet luxury and organic modern design, the Chelsea Alabaster Flush Mount Ceiling Light pairs a clean-lined, square brass backplate with a hand-carved natural alabaster dome shade. Casting a soft-diffused, atmospheric glow that highlights the stone’s intricate natural veining, this architectural low-profile ceiling fixture adds warmth, texture, and understated elegance to low-ceiling spaces. Perfectly suited for transitional, mid-century modern, and contemporary American interiors, it serves as an ideal hallway flush mount, entryway ceiling light, stylish walk-in closet accent fixture, or moody powder room overhead light that anchors any space with timeless sophistication.

Please Note: Each piece features unique natural veining.

The alabaster story

Quarried in Spain, glowing from within

Spanish alabaster is a soft, translucent stone. Cut into shades a few millimetres thick, it turns an LED into a warm, even glow with the veining floating inside. Each shade is cut from its own block, so tone and pattern differ slightly from piece to piece — that is the material, not a fault.

Placing a flush or semi-flush light

Ceiling height decides the mount; room size decides the diameter.

Ceiling heightUnder 8 ft use a flush mount; 8–9 ft a semi-flush hanging 6–12″; keep 7 ft clear below in walkways.

Room sizeLength + width in feet ≈ diameter in inches — a 12 × 14 ft room takes a fixture around 26″.

LightFor a main light aim for about 20 lumens per square foot; warm white (2700–3000K) reads best on brass and stone.
