Satin or polished finish

The smaller the grain, the more gloss is obtained. Depending on the number of steps realized, the desired gloss obtained will be a satin or polished.

Polishing of the stone will enhance its natural color but the different treatments can still be applied. Grinding opens the stone and reveals the structure.

We often speak about crystallization of polished stone. This term (very large and often overused) basically covers additional treatments to polish stones to obtain a high gloss mirror effect. More info…
