Giallo Siena marble is a marble characterized by an intense yellow background with veining that ranges from ivory white to ochre yellow or reddish tones. It has been appreciated since antiquity for its brightness and uniqueness, and is used in claddings, flooring, and ornaments, including in famous works such as the mosaics of Siena Cathedral.
It is quarried in the Sienese hills, in Tuscany, and is used for flooring, wall coverings, decorative objects, and architectural elements, both for interiors and exteriors.
