WALL SCONCE | TETHYS

$359 $399
-10%

TETHYS hangs a full disc of natural alabaster from a single black steel arm, the stone held at one point and lit from the front so the light passes through it.

Alabaster is translucent, and every slab carries its own clouding and its own veins. No two discs light up the same way, and the one that arrives is yours alone.

A full moon caught on a hook.

An Ornament That Happens to Light

Hung above a sofa or beside a console, the disc reads first as a piece of stone on the wall, and only then as a lamp.

Alabaster does not bounce light back at you, it lets it through. The glow rises from inside the material instead of off its surface, so it stays soft and never glares.

Switched off, the pale circle still holds the wall, and the veins keep their drawing in daylight.

Cut and Polished with Diamond

The disc starts as a raw block of alabaster. A diamond blade cuts it under a constant flood of water, because the stone splits the moment it heats or the tool runs dry.

The circle is then worked down and polished with diamond discs, a little at a time, until the face is even and the edge is clean. Alabaster is soft and brittle at once, so anything faster breaks it.

Every block carries its own clouding, so every disc that comes out of one is different from the last.

How a Galaxy light comes to life

A good drawing is not enough: the material still has to accept becoming it. Before a shape is approved, we go through it with the workshops that will make it, to find out what can genuinely be machined. Here is how one of our pieces came to be.

The style

It all starts with a trend. Our team follows what is circulating on Pinterest, Instagram and the interior blogs, and picks up the styles that are rising. When one of them keeps coming back and there is something worth inventing around it, we go to the workshops with a direction: here is where we want to go, what can you do in that style? This one was wabi-sabi, with its raw materials, imperfect surfaces and muted colours.

At the same time we look at the rooms the light will have to live in. Most of ours are deliberately versatile: this one sits as easily in a bedroom as in a hallway or a low-ceilinged living room. Only a few pieces are tied to one spot, like a sconce made for a headboard or a pendant sized for a kitchen island.

Choosing the material

Wabi-sabi calls for stone, but not any stone. Marble is too polished for it, slate too cold. Travertine has open pores that hold the light instead of bouncing it away, and a warm beige that turns golden once lit from within. Its natural pitting means no two pieces come out identical, which is exactly the point of this style. And because stone on its own reads cold, it needs a counterpart: a visible wood grain in a dark tone, deep enough to anchor the centre without weighing the piece down.

What can actually be made

This is where a lot of pretty drawings die. Wood is forgiving: it bends, it sands, it takes a stain, and a mistake can be fixed. Stone does not. Travertine is hard, brittle, riddled with cavities, and it forgives nothing: let the blade overheat and the piece cracks. So before going any further, we check with the workshop that the shape can actually be cut, from the diameter to the thickness of the rim and the hollow in the middle, and that they have the tooling for it.

Drawing and prototyping

Two offset circles: a wide stone disc that washes the ceiling with light, and a narrower band holding the diffuser. Those proportions get drawn and redrawn, since a stone rim that is too thin looks cheap and too thick turns heavy. Then a real piece is built and switched on, and we watch the halo on the ceiling, the warmth of the tone and the way the pores of the stone catch the glow.

From block to piece

Travertine leaves the quarry in blocks, sliced into slabs with a diamond wire. Far from all of it is kept: we look for an area with enough pitting to stay alive, but no cavity wide enough to weaken the cut. A good part of the block ends up as offcut, and that is the price of this stone. The piece that makes the cut is shaped with a diamond blade under water, the water keeping it from overheating and chipping, then hollowed out, sanded in finer and finer passes and consolidated where the cavities run deep.

Packed and shipped

Once the light is right, the workshop runs the series. The pieces reach the warehouse, where they are packed one by one before being shipped, on their way to light up a new home.
