Black travertine and walnut —
cosmic unknown, grounded beauty.
Unveil a new dimension of lighting with the Cosma Ring Pendant. A cylindrical black travertine body with a subtly rugged surface is encircled by a warm, richly toned walnut wood band — a natural embrace that softens the stone’s industrial edge. Suspended on a sleek black cord, it emits a soft, inviting glow ideal for kitchen islands, dining tables, or sophisticated commercial spaces.
Travertine notices
About the black travertine — genuine natural stone with a matte black surface finish
The body of this pendant is made from genuine travertine stone. To create a deep, even black aesthetic, the stone surface is finished with a matte black coating — rather than left in its natural off-white state. This is an intentional design choice: the weight, density, and natural pore structure of genuine travertine are preserved, while the surface colour is controlled. The entire stone presents a consistent matte black — this is exactly as it was designed to be.
Natural travertine — formed by geological processes
Travertine is formed in the natural environment through thousands of years of complex physical and chemical processes. Even beneath the black surface, the pore distribution and stone characteristics of each piece remain entirely unique.

What bulb base does this pendant use?
— not E26/E27. Please purchase GX53 bulbs specifically, as standard Edison-base bulbs are not compatible.
Is the travertine naturally black?
No — travertine is naturally off-white. The matte black finish is a surface coating applied to the genuine stone as an intentional design choice. The natural pore structure, weight, and density are fully preserved beneath.
Can the cable length be extended?

Yes. Compatible with North America, Saudi Arabia, Europe, and Australia. AC 110–240V.
