![](cache/black-galaxy.jpg) | Marble is a metamorphic rock resulting from the metamorphism of limestone, composed mostly of calcite (a crystalline form of calcium carbonate, CaCO3). It is extensively used for sculpture, as a building material, and in many other applications. The word 'marble' is colloquially used to refer to many other stones that are capable of taking a high polish . ...view marbles | ![](cache/bidasar-brown-marble.jpg) | Granites are usually a white, black or buff color and are medium to coarse grained, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy. Outcrops of granite tend to form tors, rounded massifs, and terrains of rounded boulders cropping out of flat, sandy soils. ...view granites | ![](cache/fossil-flagstone.jpg) | Sandstone is a sedimentary rock composed mainly of sand-size mineral or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in earth's crust. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, gray and white. ...view sandstones | ![](cache/deoli-green-natural.jpg) | Slate is a fine-grained, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low grade regional metamorphism. The result is a foliated rock in which the foliation may not correspond to the original sedimentary layering. ..view Slate | ![](cache/kota-brown-limestone-t.jpg) | Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). Limestones often contain variable amounts of silica in the form of chert or flint, as well as varying amounts of clay, silt and sand as disseminations, nodules, or layers within the rock. ...view Limestone | ![](cache/mosaics.jpg) | Mosaic is the art of decoration with small pieces of colored glass, stone or other material. It may be a technique of decorative art, an aspect of interior decoration or of cultural significance as in a cathedral. Small tiles or fragments of pottery (known as tesserae, diminutive tessellae) or of colored glass or clear glass backed with metal foils, are used to create a pattern or picture. ...view Mosaics | ![](cache/stone-handicrafts.jpg) | Stone carving is an ancient activity where pieces of rough natural stone are shaped by the controlled removal of stone. Owing to the permanence of the material, evidence can be found that even the earliest societies indulged in some form of stone work. ...view handicrafts |
