Camargo is quarried from a bedrock quarry in Chihuahua, Mexico. Formed in hot springs, this sedimentary stone is composed mainly of calcite calcium carbonate. Over millions of years, water has penetrated deep into the stone through small cracks and fissures, causing the iron oxide and other minerals to oxidize. It is this process that produces the slight rust veining that can be visible in this limestone. Arizona Tile stocks Camargo in a honed finish as well as a tumbled finish to enhance any design. Due to the nature of the tumbled finish, a stone enhancer will accentuate the natural colors in Camargo that may be subdued after going through the tumbling process. This limestone is filled with a colored cement three days before the honing process, allowing time for the cement to dry. During the dry summer months, the cement will cure faster, and in the more humid parts of the year, the cement will dry much slower. This variation in curing can alter the overall tone of the fill.
