Diamond Black

Diamond Black Acoustic Cork Wall Panels

Deep black diamonds in sculpted natural cork, 30 mm of acoustic depth that turns a flat wall into a feature.

Diamond Black is the boldest expression of this 3D panel collection: a faceted diamond relief pressed from compressed agglomerated cork and finished in a dramatic black. Light rakes across the peaks and valleys of each panel, so the wall shifts in tone through the day instead of sitting flat like paint or wallpaper.

At 30 mm (1-3/16 in.) thick, this is the deepest profile in the range, which runs from 5 mm up to 30 mm. That extra depth is not just visual. Cork's natural cell structure gives the panel real acoustic and thermal mass, diffusing sound and adding warmth to the room it faces.

Each diamond-shaped panel covers 0.052 m² (0.56 sq. ft.) and ships three to a package. The panels are lightweight, so installation is straightforward and DIY-friendly on both walls and ceilings, in homes or commercial spaces. Because cork is a natural, biodegradable material with hypoallergenic properties, you get the statement wall without compromising indoor air quality.
