The Geological History of Giallo Siena Marble
Marble is a metamorphic rock, which means it began as something else. Giallo Siena Marble started as limestone or dolomite, deposited as sediment in ancient seas. Over millions of years, heat and pressure from tectonic activity recrystallized the calcium carbonate, creating the dense, crystalline stone we quarry today.
The Giallo Siena Marble we use today was quarried in Siena, Tuscany, Italy. It formed during the Jurassic period. At 3.5 on the Mohs scale, it is a softer stone, prized for its workability and aesthetic qualities rather than extreme durability. Its density of 2.71 g/cm3 puts it in the heavy and dense category for natural stone.
