It is the greyer selection of the Invisible collection. The Invisible, or otherwise known as Iceberg, quarry is located in Balikesir. Ionic Stone is proud to be the only manufacturer that has mastered the technique to process the blocks of this stone into tiles. We apply high-quality UV-resistant epoxy onto the front, and epoxy & mesh onto the back of tiles. Epoxy strengthens the structure of marble. All our tiles are chip-bevelled and carton-boxed to prevent breakages during handling.
