Midnight Sky is volcanic andesite from Indonesia, hand-cut into calibrated tiles and honed to a smooth matte finish.
Its charcoal-gray base is scattered with fine mineral inclusions that catch the light, bringing depth and contrast to the surface. It is chosen for spaces where subtle details define the character.

Installation & Care
For best results, installation should be carried out by qualified professionals using materials suited to each application.
A properly prepared substrate—level, stable, and clean—is essential. Adhesives should be selected according to the environment, particularly in wet or exterior areas.
Grout and sealers should be selected according to the intended use.
For ongoing care, regular cleaning with products suitable for natural stone is sufficient. Acidic or abrasive cleaners should be avoided.

Softens the day
The honed surface diffuses sunlight instead of reflecting it. Palm Shade reads warm at noon, gold at sunset, and quiet under cloud; without glaring back.
- No harsh reflection
- Reads as fabric in low light
- Photographs warm at every hour
Cool, then warm
A natural limestone, slow to absorb and slow to release heat. The surface stays comfortable underfoot in sun, and under hand on a wall. Honed to a fine matte; close to the skin, never abrasive.
- Comfortable barefoot in summer
- Smooth matte, never abrasive
- Naturally slip-resistant when wet
Patinas, doesn't fade
The tone deepens slightly with use and exposure. Variations that were quiet at install become more present as the stone settles into the room. The patina is the point.
- Ages into the project, not against it
- Variations become richer with use
- Sealed once, easy to maintain for decades
