Ranieri, the world’s premier laboratory of experimentation with lava, collaborates with architects, designers, project managers, and other professionals to allow them to imagine new cutting-edge designs in lava exploring fresh territories of cut, color, and form, with a mastery of the volcanic stone, and a wider palette of Vietri-style glazes than is possible with other materials — an unrivaled ability with lava that’s made Ranieri the choice for extraordinary projects for the artist Olafur Eliasson, the Four Seasons Miami, Massimo Bottura’s Ristorante Francescana, and many others.

With extensive customization and contract services as well, Ranieri offers its acumen and experience to further foster creative design and an array of capabilities unique to lava stone — new techniques that enable lava stone to convey its singular volcanic characteristics, using novel cuts, edges and profile applications, and exalting the material’s mineral-flecked and elementally varied composition. A philosophy that prizes nature guides Ranieri’s aesthetic and technical innovations, as well as its ecological treatment of this precious volcanic resource.

to complete the product, Ranieri offers six different types of edges to frame the surfaces

in particular: Sharp, a cutting and precise edge; Round, with softer and organic curves; Cut, an artistic and elegant interpretation of imprecision; Bevelled, raising the surface into an even more three-dimensional effect; Tapered, pointed towards the top; 45°, ending in a dynamic angle.


The edges can also be kept Cover-Less or treated in Covered-Up, giving life to different finishes and treatments.
