The Lava stone may be subject to variations in shade and occasional “aesthetic imperfections” that are just peculiar characteristic of both natural stone and handcrafted finishing.

The understanding of the gray and enameled lava stone features is a crucial step, through which our partners and our customers will fulfill their expectations as regards quality and beauty.

Buying a lava stone product, you should be aware that the product may, on occasions, include: pinhole cavities, darker spots, green spots, mineral spots, for which there is a tolerance parameter as shown in the photos.

Another peculiarity of the lava product is the possible slight variation in the size, in the range of +/- 1.5 mm, due to the dilatation during the firing.

The enameling process itself may cause a variation in the thickness of the piece, in the range of +/- 0.5 mm.

It is also possible that the pieces bend slightly (2/4mm approximately).
