Natural Stone
Granite: A visibly granular, igneous rock generally ranging in color from near-white through the spectrum of golds, pinks, greens and blues, to grays and blacks. Granite consists primarily of quartz and feldspars.

Limestone: A sedimentary rock composed principally of the mineral calcite (calcium carbonate), the mineral dolomite (double carbonate of calcium and magnesium), or some combination of the two.

Marble: Carbonate rock possessing a distinctive crystalline texture, composed principally of the
carbonate minerals calcite and dolomite, singly or in combination.

Slate: A microcrystalline metamorphic rock commonly derived from shale, primarily composed of mica, chlorite and quartz.

Travertine: A type of crystalline or microcrystalline limestone with a distinctive layered structure. Some layers contain pores and cavities which create an open texture.

Quartzite: A highly hardened, typically metamorphosed member of the sandstone group that
contains a minimum of 95% free silica.

Sandstone: A sedimentary rock composed mostly of mineral and rock fragments, containing a minimum of 60% free silica.

Shell Stone: A sedimentary stone found in Florida and Central America, sharing characteristics of limestone, with fossils and shells imbedded in its body.

Tumbled Stone: Marble and travertine tumbled in a solution of water, sand and mild acid, producing tiles with an old-world, weathered look.

Cantera Stone: A sedimentary rock found in riverbeds of certain regions of Mexico. Predominantly of five colors, it is used extensively in the Southwest United States for Architectural columns and moldings, and for paver tiles.

Agglomerate Marble: A man-made product usually consisting of marble or quartz chips in a resin body.
