Crafting lava at its workshop at the foot of Vesuvius, Ranieri brings together the supreme artisanship of Naples’ centuries-long volcanic stone tradition with a contemporary vision of design that exalts the material’s natural form.
Expert in project and contract design as well as installation, Ranieri provides the most thorough and visionary bespoke service to help clients create environments using lava as it’s never been seen before, harnessing the power of its natural beauty to design distinctive tiles and wall claddings, bars, reception desks, bathroom fixtures, furniture, and more.
With its acumen in building, Ranieri goes beyond design to construct and execute projects, ensuring that every collaboration is skillfully and properly completed by artisans of the highest caliber.

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.
