"Natural Stone" refers to a number of products quarried from the earth, used over many thousands of years as building materials and decorative enhancements. These products include Granite, Marble, Limestone, Travertine, Slate, Quartzite, Sandstone, Adoquin, Onyx, and others. They are more than just rocks – natural stone is hand selected from the best, most consistent sources for durability and beauty. Natural stone products differ in composition, color, and texture even among pieces from the same source. This is usually considered a benefit, lending itself to one of a kind designs and distinctive, dramatic applications.
Natural Stone has mainly been used for large-scale construction and in formal applications such as House,Landscaping, big and small commercial and residential projects, government buildings. It has also been used for road construction and monuments. For residential construction, wood and brick have been the traditional choice. However, there has been a growing trend in recent years to use Natural Stone in residential construction for both structural and decorative use. Popular applications include entryways, atriums, bathrooms, fireplaces, floors, countertops, and many other surfaces.
Natural stone is prized its distinctive beauty and the sense of peaceful tranquility it creates, but there are also many practical benefits to using Natural Stone in your home. Natural Stone products are more durable than many artificial products, often lasting for decades with very little maintenance. With Natural Stone there are no worries about exposure to harmful chemicals in the home or released into the environment during production or disposal. Why invest time and money into a look-alike? Natural Stone is the real thing that the artificial products try to emulate.
For maintenance-free elegance and durability, granite is unmatched. Its incredible strength and density makes granite the perfect choice for massive structural work – walls, monuments and supports. Though it is the hardest of structural stones, the amazing variety of mineral-rich colors and natural patterns gives it ornamental value as well. Granite products are ideal for flooring, countertops, vanities and decorative exterior applications.
With a uniform texture, an appealing variety of colors and finishes, and weather resistant durability, it's easy to see why sandstone products have been used for thousands of years for walls, floors, and pavers. As with other types of rock, its variations result from differing mineral composition – there's a sandstone product to match any décor.
Prized for its timeless style, texture and high-gloss polish along with a rich palette of beautiful colors, marble has a place anywhere in the home. Available in solids or dramatic veined varieties, marble may be carved or sculpted in many ways, making it one of the most versatile decorative stones. Often seen as a symbol of luxury, modern technology brings beautiful marble products even to budget-conscious homeowners.
Formed over thousands of years of sedimentary deposit and compression, slate splits naturally into beautifully textured layers. The various shades of slate products – brown, yellow, dark gray, pink, lavender and more – may even occur within the same piece of stone. Durable and stain-resistant, slate products are often used for flooring, cladding and landscaping.
Shimmering and sparkling with tiny quartz crystals, Quartz is a rock similar to slate with a medium grained texture and incredible durability. Differing mineral content creates many color variations, from the sedate white, gray or beige to more adventurous shades of purple and pink. Quartzite is widely used for wall veneers and decorative tiles. A naturally non-skid texture makes it a perfect candidate for flooring indoors and out, including areas with heavy traffic and exposure to the elements.

The muted, soft tones of limestone are perfect for today's casual and comfortable lifestyles. Available in hues of soft beige and tan, either polished or honed, limestone products are ideal for bathrooms, fireplaces, countertops and flooring in low-traffic, informal areas.
Valued for its banded, pitted "distressed" appearance, travertine adds rich, distinctive character to a variety of indoor and outdoor building projects. Its patterns and veining effects were formed by hot spring water percolating through underground limestone. When used for interior applications, travertine is often filled with cement, grout or resin and sealed to create a smooth, stain-resistant surface.
A translucent stone with a glossy, polished surface, onyx is composed of crystalline silica and closely related to agate, a semi-precious stone. Often found in caves, onyx is formed by the slow flow of cold, carbonated spring water. Onyx is available in pastel shades of yellow, brown, green, orange, and white.
The most important difference is this – Natural Stone is a product of nature, and Ceramics are man-made. Most man-made materials cannot compare in durability to natural ones. While damaged ceramic tiles usually need replacing, natural stone usually needs minimal restoration if stained or scratched. Other differences are explained below:
Natural Stone can be used on nearly every surface both inside and outside the home, including floors, kitchen countertops, vanity tops, bathrooms, patios, walkways, fireplaces, facades, wall cladding, and garden landscaping.
Countertops in kitchens and bar areas are often exposed to acidic substances such as lemon, vinegar, alcohol, and tomato sauce. Knives, dishes, pots and pans, and other implements may cause scratching of lesser materials. Granite is the hardest and densest of all natural stones – the feldspar content keeps it water resistant, and the silicates it contains won't react with acid. These properties help Granite resist staining and retain its fine luster over a longer period of time than ceramic tiles or other stones.
Although Marble is commonly requested for countertops in bars and kitchens, marble's high carbonate content makes it vulnerable to acidic substances.
The earth tones and rustic look of slate create a comfortable, natural look that is right at home with exterior landscaping and interior garden designs. Slate is naturally slip resistant, even when wet, and is much less likely to show dust and dirt than polished granite or marble. It's also relatively low priced, which makes it a great choice for large, informal areas.
Natural stones are quarried directly from the earth's crust, and every piece is unique. The only processing they need is shaping into various forms, sizes and finishes.
Sources of natural stone with desirable qualities in many different locations in India. Indian stones better than others due to the stones' appearance, hardness, and other qualities.Mostly stone quarried in India.
Cost of processing is also a factor. Since natural stone has been used as a building material for thousands of years in many locations , those areas have a long-established system for quarrying and processing these stones which is efficient and economical.
Natural stone from different areas contains a varying mix of mineral deposits and rock formations. For example, the mineral Mica may be found more frequently in some areas, which means that the rock from that location will contain bigger shiny crystals than we would find in places where less Mica is found. Some countries quarry more limestone than granite. Therefore, stone from certain places may be better suited for one application than another. Natural stone qualities and characteristics differ due to geological formations, not geographical boundaries.
Some types of stone are better suited for interior applications than exterior because they cannot withstand harsh weather extremes and may crack, crumble, or fade. Also, stones with naturally slip-resistant surfaces are better for outdoor walkways or patios than those with smooth, polished surfaces. Some multicolored slates bleed color upon contact with water.
Natural stones tiles and slabs for commercial and residential applications do not emit harmful radiation. becoz of natural stone made naturally
Stones that are harder and denser are more difficult and expensive to quarry and process. Quarrying methods vary as well; stones may be quarried below ground, which is more expensive than above ground. Also, since natural stone is quarried all over the India, long distance shipping factors into the price.
The larger the stone, the more difficult it is to process, handle, pack, and transport. Larger sizes also tend to have a higher amount of waste compared to the part that is used, which makes them more expensive.
The availability of a particular stone is the most important factor in determining price. However, handling and transportation cost does drop slightly for a larger quantity.
| Natural Cleft | Grinding, sanding, and buffing produces a high gloss, mirror-like surface. |
| Polished | Grinding, sanding, and buffing produces a high gloss, mirror-like surface. |
| Honed | Grinding and sanding produces a smooth, yet not glossy finish. This is best for low maintenance, high traffic applications. |
| Flamed | A flamed surface is achieved by subjecting the stone to the high temperature flame of a torch and burning most of the carbon content, leaving textured quartzites with gentle coloration. |
| Sandblasted | This is a rough, but tidy look created by applying a high pressure blast of sand to the stone's surface. |
| Rivar Wash | This finish is often given to granites, and provides a non-slippery surface while retaining the coloration and grain structure of the stone. |
| Leather | Available only in Melange marble, this finish gives the stone a suede look and feel. This texture is smooth and slip-resistant. |
| Tumbled | Tumbling stones in a solution of sand, water and mild acid creates an old world, weathered look. |
| Split Face | Mainly used for cladding, this is achieved by splitting stone either by hand or by machine so that the surface exhibits a natural quarry texture. It has a flat back and uneven front surface, and creates the uneven look of protruding bricks. |
| Fleuri Cut | This is achieved by cutting quarried marble or stone parallel to the natural bedding plane. |
| Cross-Cut | The cross-cut method involves end-cutting blocks of travertine to display a less linear, more rounded "wavy" pattern. |
| Vein Cut | Opposite of cross-cutting, the veining of the stone is shown as a linear pattern. |
| Veneer Stone | Any stone used as a decorative facing material as wall cladding which is not meant to be load-bearing. Veneer may be made from different finishes, such as split face, cleft, honed, polished, flamed or tumbled. |
Natural stones is cleft out of blocks to form tiles. When it is cleft by machine or saw, it is Machine cut because a uniform thickness is formed. Natural Cleft stone is hand-cleft and its thickness may vary up to 5/8 of an inch.
"Natural stone is considered one of the softer natural stones. Bullnose stone tiles are rounded tiles used for corners and edges. It is advised that stone bullnose tiles be fabricated by a professional using a grinder and bugging pad.
Edge Finishes Various edge finishes include chipped, pillowed, bull-nosed, beveled, chamfered, and others.
There are three important reasons for choosing one finish over another in certain applications.
When choosing flooring, it's important to choose a slip-resistant surface for outdoor applications where the floor may become wet. Highly polished surfaces should only be used for interior floors. Also, highly clefted, uneven surfaces may cause a tripping hazard when used for flooring.
Softer, less dense stones such as marble or limestone are unsuitable for high traffic areas because they will quickly become dull and will need frequent restoration to maintain their finish.
The application should be consistent with the type of finish selected. A rough finish such as flamed would be a poor choice for countertops, due to the difficulty in cleaning it. Clefted material should not be used for tabletops, because it would present an uneven surface.
Polished flooring may be used in a commercial application if the floor is unlikely to become wet and slippery. It is advisable to have the floor material professionally tested prior to installation. Sealers are available that can improve the slip resistance of the surface without removing its gloss.
A honed finish creates a soft, matte, appearance that is more suited to casual, comfortable environments than a formal, polished surface.
Slate with a heavily cleft finish may create a tripping hazard. Most slates are lightly clefted and suitable for flooring in kitchens, bathrooms and on patios. A pallet of slate may contain a few pieces with heavy clefting, but these are generally not used for the flooring installation.
Polished stone surfaces may become slippery when wet, and tend to lose their shine in a short time due to weathering.
The thermal, or flamed finish is achieved by subjecting the stone to the high-temperature flame of a torch. This burns off most of the carbon content, creating textured quartzites with gentle coloration. Only granite is tough enough to withstand this treatment, and the piece must be fairly thick or it may crack or break under heat and pressure. This is a popular finish for commercial wall and flooring applications.
Tumbling stones in a solution of sand, water and mild acid creates an old world, weathered look. Typically sizes of 5/8" X 5/8" to 6"X 6" and sometimes even 8"X 8" are true tumbled pieces. Larger sizes are given a "Tumbled" finish, manually. Very small pieces like 5/8" X 5/8" & 1" X 1" are usually, mounted on 12" X 12" meshes for ease of installation. Most commonly used size is 4" X 4" and it is used in straight & diamond patterns, or as accent pieces. When mixing different size tumbled pieces, the look may vary.
Tumbled stone pieces are intended to produce a rustic, old-world look. Therefore, they are not created with precision and may vary slightly in size. Some pieces may have large chips on the edges or may have a corner missing. Care must be taken to ensure an even surface when installing tumbled stone flooring.
Stone Installation Can I specify that there be no grout joints? Creating an installation without visible grout joints is difficult, but if the surface of the floor is straight and the tiles are perfectly cut, very little grout should be seen. A professional, experienced installer should be chosen to create this look.
The tightest grout joint that you may request is 1/16".
Because stone is a natural product, there is always some variation within a selection. By sorting out the stone tiles before installing, it is possible to place the tiles on the surface before installing, blending the varying colors, grain, and veining as desired.
Open all boxes and mix up all of the pieces before installation. This will help to create a visually pleasing distribution of stone variation.
A good installer knows that some other stones require water-free epoxy thin-set.
When stone is installed on a concrete slab at ground level, ensure that a proper moisture barrier is in place prior to installation.
Grout is an important design element. Because it is used to fill the spaces between each tile, the grout must be selected carefully. A wide variety of grout colors is available to enhance the beauty of the tile installation and may be chosen to contrast with, match, or accent the tile.
Contrast Grout: emphasizes a pattern created by the tile.
Matching Grout: blends seamlessly with the tile.
Accent Grout: a shade slightly different from the tile, gives them an appearance of depth.
A water saw with a diamond blade is recommended for cutting all marble tiles.
No. It is not recommended that marble tiles be installed directly on wood flooring or any other flooring that moves. The movement can cause tile to crack. The best solution is to have cement board installed by a professional installer over the surface to be tiled.
Depending on the installation pattern, experts recommend adding 10%-15% of the total square feet of the project to ensure you have enough natural stone tile. It is advisable to add another 5%-10% for future fixes in the event of breakage.
It is recommended that porcelain tiles be installed with a minimum of 1/8" lines for grout.
Mosaic tiles can crumple under normal cutting conditions. It is important to secure the tiles between wood or other solid tiles to firmly hold them while using a wet saw fitted with a diamond blade.
It's recommended by professional installer to use modified thin set, according to the manufacturer's instructions on the package.
Non-sanded grout is recommended for glass mosaic tiles. Sanded grouts will dull the finish.
Generally, 1x16" or 3/16" V notched trowels are recommended depending on the size and thickness of the mosaic tile.
Yes. There are self-adhesive sheets available on the market to install mosaic tiles on vertical surfaces and walls. Follow the instructions provided by the manufacturers.
Mesh-backed landscaping tiles can be installed on solid level surfaces including concrete.
1/2" quare notch trowels are recommended for spreading mortar on landscaping tiles.
Pavers can be set in sand with the proper installation procedure and materials.
0.5" of mortar is recommended for the intallation of landscaping tiles.
Natural stone is available in a nearly endless variation of colors, patterns and veining. These may include shades of beige, gray, gold, red, pink, blue, and green.many more
Granite, Marble,Sandstone,Limestone and slate may be available in nearly any color, so it may be possible to specify stone color, with some tolerance for shade differences. Not all stones are available in all colors, however. Travertines, for example, are only found in shades of beige, yellow, and gold.
The criteria for selecting stone color will depend on the application. Color choice can make a room appear larger or smaller, formal or warm and inviting. Consider the following characteristics:
Lighter colors tend to make a smaller room seem larger.
Dark colors tend to make a room more intimate and cozy.
Solid colors, smooth and polished tiles show more dirt and require more maintenance.
Patterned material, usually in a honed finish, is one of the easiest to maintain.
Dramatic patterns can help highlight and accent portions of the room, including architectural features.
Softer, less dense stones such as marbleEach stone is unique, and some types of stone display more variation between the pieces than others. Granites show little variation in color, but may have differing patterns and grain density. Slates tend to show a wide variation in color, even within the same pallet of stone. or limestone are unsuitable for high traffic areas because they will quickly become dull and will need frequent restoration to maintain their finish.
The neutral tones found in natural stone include beige, tan, and cream. Most people enjoy these colors, and find that they complement all types of furniture and fixtures.
Any color may become an accent color, contrasting with the main color in the room. For example, a white stone border can accent a black floor.
The grain structure in a piece of stone was formed during an igneous stone's cooling process. The slower the stone cooled, the larger the grains. "Grain" refers to the crystalline and flowery patterns visible on the stone's surface. Some stones, particularly marble and granite, have a great amount of veining, which is caused by the distribution of various minerals within the stone.
Many popular items are readily available from current stock. Others may take 90 to 120 days for delivery.
Since stone is a natural product, it is not possible to order a specific stone.
Standard stone tile sizes include squares of 4", 6", 8", 12", 16", 18", and 24".
Standard thickness for 12" square tiles is 3/8".
Standard thickness for 16"-24" square tiles varies from 0.5" - 0.75".
Slab sizes vary from 104"x70" to 125"x80". Smaller sizes are available as well.
Thickness of slabs is generally ---------------
Slates and Quartzites are produced in nominal sizes, not exact sizes - a 12" square tile may actually measure 11.87" square.
Tile size is a personal choice, but should be proportionate to the size of the room. Smaller spaces should use smaller tiles in order to make the most of the stone's color and other qualities.
The thickness of a kitchen countertop is generally either 0.75" or 1.25". the larger thickness is preferred, and western consumers prefer the thinner.
Granite is a natural stone, and composite stone is a man-made material. As a plastic-based material, composite stone is more prone to scratching, deformation and loss of finish due to heat. Granite is more durable, easy to maintain, resistant to scratches and stains – and much more appealing to the eye. Granite is available in a wider range of colors than composite stone, and costs less as well.
Thickness tolerance varies from stone to stone. Slates generally have a tolerance of 0.38", and granite tiles have a tolerance of 0.06".
A combination of different sizes may be placed together to create a pattern, which adds to the beauty and uniqueness of the stone installation - and is very trendy!
Stone surfaces are very easy to maintain. Clean stone floors with warm water and a mild liquid soap. Never use acid cleansers or abrasive chemicals on stone. Natural stone should be sealed after installation and every one to two years thereafter, depending on its application.
All natural stone including marble and granite, must be properly sealed to protect againt staining. Without proper and regular sealing, granite and other natural stones are pourous and can absorb spilled substances and leave unsightly stains and marks.
A sealer that penetrates and protects natural stone and tile can be purchased at any home improvement or hardware store.
If your marble tiles, travertine tiles or granite countertops have a stain, consult a restoration professional. A Poultice kit is another stain removal option, this product can be found at most home improvement stores.
Neutral cleaners are needed to clean natural stone tiles. Acidic or alkaline cleaners should be avoided as they can open the pours of the natural stone and change the color of the surface.
