Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.

The actual extraction of limestone is made by separating the rock in quarry ledges and dividing it into blocks. Here is an overview of Vetter’s Stones extraction process: The overburden, or the material above the stone that is set to be harvested, is lightly blasted and removed. The majority of that debris (backfill) is temporarily removed
