Essential Information
We hope you feel inspired to choose our stones. Please read on for more information regarding the unique characteristics of stone and finally advice on how to place an order with us.
Stone... A Natural Phenomenon
The journey begins from the earth to your home when blocks of stone are extracted from huge quarry beds by large cutting machines. These blocks are then transported to a factory where they are cut into slabs by water-cooled gang saws. The slabs are then machined to give a honed or polished finish to the surface and cut into various size tile formats. Further specialist finishing methods can then be employed to produce a variety of ‘antiqued’ surfaces and edges. The geological complexity of stone results in natural variation from tile to tile; this is why all natural products exhibit their own individual characteristics. Whilst we work closely with suppliers to select our stone and take great care to show representative displays, images and samples, a degree of natural variation is beyond our control and will inevitably occur. This is part of the beauty of natural stone, to help appreciate the extent of any variation, it is important that you view as much stone as possible before placing your order and ensure enough stone is ordered initially, including extra, as batch variation may occur between orders. On a final note you must ensure your stone installer blends the tiles prior to fixing, so that the spectrum of shades are distributed evenly. Many of our stones are available in a variety of finishes, each of which will alter the appearance and shade of an individual stone type; a polished finish will intensify the colour and any markings within the tile, whereas a tumbled material will appear more muted and subtle. Shade variation can occur between different sizes of tile in the same stone, therefore we would usually advise against mixing individual tile sizes, unless they are purchased as a set pattern. Fissures, minor blemishes and edge chipping are characteristics of many of our stones. These are to be expected and are not deemed as defects, once fitted and grouted such characteristics are virtually unnoticeable. Stone tiles are often packed wet and do not dry out until they are unpacked, therefore some of your stone may appear darker in shade until thoroughly dry. Stone tiles may vary slightly in thickness and overall dimensions. This may be due to their rustic nature or the edge finish of the stone but also because of wear on the cutting machinery and blades during the finishing process. Therefore all sizes listed within this brochure are nominal. Most of our stone, slate and terracotta tiles are supplied in their raw and natural state. Once fitted and sealed your tiles will have a far more finished appearance. For more information on fixing, sealing and maintenance please refer to the relevant section.

Geological rock types
Limestone
Limestone is a sedimentary rock formed by the consolidation of sediments, seashells and other organic matter. This calcareous stone forms our largest product range. Each limestone exhibits its own characteristic colours and markings. Some degree of edge chipping can be expected together with occasional surface pitting, fossilised shells, fissures and mineral striations.
Travertine
Travertine is created by hot mineral springs. The result of this method of formation is a honey-combed structure which when finished has visible surface pitting and voids. Our travertine is available in either ‘filled’ or ‘unfilled’ finishes. With an unfilled travertine the surface voids will be filled with grout during the installation process. Filled travertine has had these pits and voids filled at source with a colour matched stone resin. Whilst this gives a smoother surface, through general usage, some small areas of fill may dislodge or previously unexposed holes may become visible. This is not unusual and the holes should be re-filled with a suitable resin or grout.
Marble
Marble is a metamorphic rock historically used in ancient buildings. Marble encompasses a vast spectrum of colours with mineral veining generally contrasting to the base stone colour. Some marble tiles or slabs may have a meshed backing or resin on the rear to help strengthen the tiles when the veins are particularly predominant. Marble is a very dense stone that readily lends itself to a polished finish.
Slate
A fine-grained metamorphic rock that is characterised by its ability to be split into broad sheets. Slate is a durable stone which presents a diverse range of colours and textures. We offer ‘riven’ slate, which has a naturally cleft surface and is rustic by its nature, with chips and chisel marks present on some surfaces. Some of our ‘riven’ slate varies in thickness or is ‘uncalibrated’ and therefore requires ‘bedding up’ with the appropriate thick bed adhesive during installation. We also offer ‘honed’ slates that are machined to create a smooth, even surface. Some of the dark honed slate can be prone to scratch marks.
Sandstone
A coarse-grained sedimentary rock formed by compressed sand deposited by water or wind. It is commonly characterised by a granular surface. Sandstone is a hard yet very porous stone that requires thorough impregnation and surface sealing when used internally. Sandstone in its large flag format is a very popular external choice.
Schist
A dense metamorphic crystalline rock that offers considerable shade variation, ranging from light pearl grey to dark gold, with an undulose, riven surface texture.
Terracotta
Terracotta is made from natural clay which has been moulded and then kiln fired to bake the clay and produce rigid tiles. The clay is either moulded by hand, these tiles offer a more rustic feel, or machine-moulded for a more consistent finish. All Terracotta tiles will be subject to edge chipping and variation which is part of the finished look of an authentic Terracotta floor. Terracotta when untreated is very porous and as such any unsealed tiles will look very different from your finished floor.
Granite
A hard igneous rock originating from the slow crystallisation of molten magma cooling deep beneath the earth’s surface, this is the hardest stone in our range. Available in a polished finish this shows off the ornate crystals which serve to make up Granite.
Basalt
A fine grained, dark coloured igneous rock generally formed from volcanic lava flows, it is made up of minute crystals barely visible to the naked eye.
Questions and Answers: Give your home the finish it deserves
Mandarin Stone have been helping people to choose the right stone for their projects for more than seventeen years. We have a wealth of knowledge and experience to share with our customers – here are some of the questions we are often asked:
Where can I use stone tiles?
Stone tiles can be potentially used for any residential or commercial project, but do check your substrate prior to fixing to enable us to advise you on installation procedures. Taking the inside out, driveways, terraces and gardens can also be paved or cobbled.
Which tiles can be used on the floors and which on the walls?
Many of our stone tiles can be installed on both floors and walls. The underlying substrates should be checked prior to installation for their suitability. Bear in mind most of our stone becomes thicker and heavier when the tile sizes are larger.
Which size tile should I choose?
The choice is yours! Mandarin Stone offer stone from the smallest mosaics to very large slabs, so there are no limits to your choice. Please note that large tiles often make an area look bigger and rectangular format tiles tend to give a room a direction whereas a square format tiles will not. Also consider laying square tiles ‘on the diagonal’ to make a room space look larger.
Is a certain type of stone better for an intended area than others?
There are often misconceptions that certain types of stone are ‘better’ or ‘more hardwearing’ than others. This is generally not the case. The look of the stone you want is essentially more important than the type.
What type of finish should I choose?
The style of the property or the 'look' you are trying to create should reflect your decision here. A smooth ‘honed’ stone or a ‘polished’ stone can create a modern or classic feel. Whereas a ‘riven’ slate or an ‘antique’ stone will give a more traditional or rustic look.
What colour should I choose?
Natural stone offers a wide spectrum of colour shades so the choice is endless! From stones that are reasonably plain and uniform to others that offer extensive tonal variation. Like any other material the lighter, plainer stones tend to be less forgiving for cleaning purposes than those that are a slightly darker and more mottled in shade.
Will my tiles need sealing?
Yes, all natural stones are porous to varying degrees and therefore need to be thoroughly sealed during the fixing process to prevent staining etc. Please go to the Installation & Sealing information for more details.
Glossary of Stone Finishes and Terminology
Alea
A finish which offers a gently softened edge to the tile and a very light surface texture.
Antique
A term which encompasses various ageing/distressing methods which achieves a worn look to the stone. Please note that where stones originate from different countries, antiquing methods will vary, and therefore ultimately the look of the stone will vary.
Brushed
A form of antique stone, which has only slight surface texture and a softly rounded edge.
Calibrated
Where the stone has been finished to a uniform thickness.
Cerato
Virtually the same as ‘brushing’. A finish which is used by the Italians in our Renaissance range, leaving the stone with a silky texture.
Chipped
Where the edge of the stone has been worked to give a hand-chipped appearance.
Chiselled
Where the edge of the stone has been chiselled by hand to recreate a traditional looking floor.
Cobble
Generally a smaller stone of greater thickness. Normally used externally.
Cross-Cut
Relates to travertine where the blocks are cut horizontally to achieve its well known mottled appearance.
Fabrication
A term used to describe the process in which large stone slabs are made into bespoke worktops, vanity tops, bath surrounds etc.
Filled
This term is related primarily to travertine. Travertine is characterised by surface pits and holes, these can be pre-filled at source by a stone resin which is as similar as possible to the colour of the stone. Not every single pit/hole may be completely filled, and therefore even a pre-filled stone may require some filling by grout during the fixing process.
Fissure
This is thin mineral veining which can be mistaken for a crack in the stone.
Flag
Generally a larger stone of a thicker depth for use externally or internally.
Fossils
Fossils are remnants of past animals or plants. Fossils can exist in many different types of mineral.
Free Lengths
A laying format for tiles, where the width of the stone is static i.e. 400mm or 600mm and the length of the tiles vary randomly. Offers a look which is reminiscent of traditional stone floors. Please see Stone Layouts on page 142.
Honed
The stone is run through a machine to give a smooth surface to the face of the stone.
Minerals
One, two or more minerals combine to form rock. They are non-living solids that are found in nature. Quartz and calcite are commonly found in stone.
Nominal
A small variation from stated sizes and thicknesses.
Opus
Where the stone is laid in a repeated pattern which gives a random effect. There are various Opus patterns depending on the stone. Please note you cannot choose a stone to come in a particular Opus, a stone will come in an Opus specified by us, please see pricing tables throughout the site.
Pillowed
A form of antique stone, where the edges have a soft, but almost pronounced ‘pillowed’ edge.
Polished
Where the stone is worked to achieve a high reflective gloss to the surface of the tile.
Provence
A finish where each piece of stone is finished by hand. Some pieces will have a soft stippled surface, whereas others will have smooth undulations. These combine to recreate the effect of an original antique stone floor.
Riven
A naturally cleft or riven face simply achieved by splitting blocks of stone. This term usually relates to slate or sandstone, giving a fairly rustic feel.
Slab
A large piece of stone which can be fabricated into worktops, vanity tops, bath surrounds etc.
Tatami
A decorative linear border tile in the marble range.
Tumbled
A form of antique stone, where the stone has been ‘tumbled’ which gives a rounded edge to the tile and the surface may be slightly textured.
Uncalibrated
Where the thickness of the tile varies to a greater or lesser degree.
Unfilled
This term is primarily related to travertine. Travertine is characterised by surface pits and holes, and an unfilled finish leaves the travertine in its natural state. This then requires the surface of the stone to be filled with grout during the fixing process.
Veining
This is the term describing the natural, irregular mineral lines found in stone.
Vein-Cut
This term relates to travertine, where the stone is cut in such a way which shows the natural striations, giving a banded appearance to the stone.

Placing your Order and Stock Availability
All materials featured in this brochure are normally stocked to a high level in our UK warehousing in Monmouth. If a product is out of stock we can normally give estimated lead times. Mandarin Stone can generally obtain any stone, size and finish, so please let us know if there is something specific you require that you have not seen in our range. These items can normally be made available in 4-10 weeks. Unfortunately Mandarin Stone cannot be held responsible for delays caused by ocean shipping, a short supply of raw materials or severe weather conditions, or any other circumstances beyond our control. We reserve the right to discontinue items as and when circumstances necessitate. New stones, together with new finishing techniques are constantly being sourced and added to our range. All prices in this brochure are ex-warehouse Monmouth UK and are subject to VAT at the current rate. Prices can change without prior notice. Our quotations and invoices normally show individual tile prices and details, therefore, the calculated square metre prices are intended as a guide only. In order to quote on a selected stone we require the square meterage, plans or dimensions. A wastage factor should be taken into account for each project prior to ordering. This is normally 10% which should allow for cuts to walls and any minor tile imperfections. We would advise the use of our recommended ancillary products such as adhesives, grouts, water-proofing systems and sealants. We know that these products work with our stones and can ultimately advise on their use and any problems which may arise. If a quotation is required for ancillary products please let us know the substrates you are fixing onto, if under-floor heating is being used and any other information which may affect the installation. We can quote on the correct products for the application. Please go to the Installation & Sealing section for more detailed information.
We operate a ‘no returns policy’ and cannot be held responsible for surplus goods, as quantities are estimates only. Therefore, please check your quotation carefully before your order is placed. At the point of order, availability of goods should be checked to help coincide with your delivery date requirements. In order to reserve your stone, full payment is required with your order. We accept all forms of payment but require cleared funds before your goods are dispatched.
Deliveries and Collections
Our nationwide delivery service is competitively priced, fast and reliable and we can arrange an export service on request. All deliveries are chargeable and are based on the weight of your order. Once an order has been placed goods can normally be dispatched within seven working days. A specific delivery date will be arranged to suit you. Most deliveries are between the hours of 9.00 am and 5.00 pm, Monday – Friday except Bank Holidays. An additional charge will be made for a specific morning, afternoon or timed delivery. Most orders are packed in either wooden crates or pallets. They will be delivered on a large lorry so it is important that any restricted access details are advised prior to your delivery. The stone will be placed, at the driver’s discretion, to the nearest safest point to the property; this may be on the drive or kerbside. The delivery driver cannot help handle the goods, so it is essential for you to arrange for a responsible individual to be present. All orders must be examined on delivery and any shortages, damages or other discrepancies must be noted on the delivery note and reported within the specified time period (see Terms and Conditions). Your delivery may have extra or broken tiles which are additional to your ordered quantity. These are normally left in to brace the other tiles and will be noted on your delivery note. Care needs to be taken when unpacking all stone tiles as spacers may need to be removed from the packaging before the tiles are lifted out. Tiles should always be stacked and stored vertically (on edge) but not on a hard surface as this causes unnecessary edge chipping. Collections can be made from our Monmouth warehouse by prior arrangement. Please ensure that a suitable vehicle is used whereby goods can be mechanically loaded. Collected goods are transported at the individual’s own risk.
