NATURAL STONE

Granite refers to an igneous rock formed as magma cools slowly. Usually, it has a pink or white color, and black spots are visible with a little bit of biotite or amphibole.

1) Coarse-grained: The size of the constituent mineral is large. It usually refers to the degree to which minerals can be distinguished by the eye.

2) Igneous rock: Made by hardening magma.

3) Essential mineral: It should be quartz, plagioclase, alkali feldspar, and the content of alkali feldspar should be higher than that of plagioclase.

Granite features

1. It is a rock composed mainly of quartz and feldspar. It is a rock formed by gradually cooling down in magma state without erupting out of the surface of the material made by volcanic activity.

2. It is hard, has high durability and strength, and is very resistant to abrasion by weathering.

3. It has the advantage of being able to produce large plates because the spacing of goldin joints created by external force applied to rocks with relatively beautiful color is larger than that of other rocks.

4. Production of domestic products is large, and most of domestic granite contains black or gray spots on a neutral gray and milky background.

5. Imported granite has a variety of colors and has small spots on the background, making it the most used stone type for interior and exterior construction.

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.

Natural marble is processed by natural marble, and it can create a luxurious atmosphere with only the material that has a unique luster and pattern.

The use of marble enhances the overall atmosphere, and because it is a natural material, there are no identical patterns or colors, creating a unique interior.

Travertine is a form of limestone deposited by mineral springs, especially hot springs. Travertine often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems. It is frequently used in Italy and elsewhere as a building material.

Travertine is a terrestrial sedimentary rock, formed by the precipitation of carbonate minerals from solution in ground and surface waters, or geothermally heated hot-springs.

Travertine is often used as a building material. The Romans mined deposits of travertine for building temples, aqueducts, monuments, bath complexes, and amphitheaters such as the Colosseum, the largest building in the world constructed mostly of travertine. The Shroud of Turin, when examined by Joseph Kohlbeck from the Hercules Aerospace Company in Utah and Richard Levi-Setti of the Enrico Fermi Institute, was found to contain particles of travertine aragonite limestone.

Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals.

Quartzite is a decorative stone and may be used to cover walls, as roofing tiles, as flooring, and stair steps. Its use for countertops in kitchens is expanding rapidly. It is harder and more resistant to stains than granite.

Limestone is a common type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more important for the last 540 million years. Limestone often contains fossils, and these provide scientists with information on ancient environments and on the evolution of life.

Limestone is very common in architecture, especially in Europe and North America. Many landmarks across the world, including the Great Pyramid and its associated complex in Giza, Egypt, were made of limestone. So many buildings in Kingston, Ontario, Canada were, and continue to be, constructed from it that it is nicknamed the 'Limestone City'. On the island of Malta, a variety of limestone called Globigerina limestone was, for a long time, the only building material available, and is still very frequently used on all types of buildings and sculptures.

Limestone is readily available and relatively easy to cut into blocks or more elaborate carving.

Popular uses include flooring, interior and exterior wall cladding, fireplaces and backsplashes. The static coloring among slabs makes it a popular choice for both current and future projects that contain expansion plans.

Onyx is an easily identifiable stone due to its bands of alternating colors from the intergrowths of the quartz and moganite. It forms in a wide variety of colors: red, yellow, brown, green and the most famous, black.

It is predominantly used as a statement piece, light accent, or as a backsplash in bathrooms and kitchens.
