Backlit stone is theatre. With the right material and the right light layer, a wall stops being a surface and becomes a glowing geological cross section.
Onyx is the canonical backlit stone. Cristallo quartzite, certain white marbles, and a small group of translucent exotics also read well when cut to one centimetre.
We engineer the LED panel, the diffuser, and the thermal management as one system. The stone is only half the result.
