Mount Montagnola, stretched over Siena city in central Italy, is clad in sunflowers, hollies, castanea mollissimas and honeysuckles. In Triassic Era over 250 million years ago, the golden breccias buried in the metamorphic stratum of Mount Apennine gave birth to the splendid sunflower-looking marble—Giallo Siena. In 301 AD, Roman Emperor Diocles claimed Giallo Siena as the royal special marble. Nowadays we can still perceive the elegance of Giallo Siena in Florence Duomo Cathedral and Florence Library. GANI Giallo Siena, produced with giallo ores and GANI unique craftsmanship, revives the magnificence and grandeur of royal marble.
