Choose your stone supply path before you request a quote
A first visit to a full-category stone supplier usually starts with one of three questions: which material, which use, or which process. This page routes each buyer to the right section and lists what to include so a written reply can cover the whole requirement.
Current stock, dimensions and test data are provided on request against source documents.
Most visitors arrive with a picture in mind, but the choice that actually unlocks this site is earlier and simpler than picking a stone: it is deciding which door to walk through. A full-range supplier can be entered from the material you already want, from the job the surface has to do, or from the stage of work you are planning, and each door leads to a different set of pages. Pick the wrong one and you will read a detailed answer to a question you are not yet asking. This opening map is here to prevent that. It describes the three entry routes, explains how the fixed sections divide the decisions among themselves, and sets out the handful of named details that let a single written note cover an entire mixed requirement. Think of it as a switchboard rather than a product pitch; the material comes later, once the route is chosen.
Three ways in: by material family, by application, or by process stage
Three doors stand at the front of this site, and each suits a different state of mind. The material door is for a buyer who already knows the family, perhaps from a sample or a specification, and wants that family's own decisions: how the slabs are chosen, how the finish is set, what goes into its brief. The application door is for someone who knows the room but not the stone, a wet terrace or a lobby floor, and needs the use case to narrow the shortlist first. The process door is for a buyer worried about how an order is actually made, inspected, packed or documented, and who wants the sequence of work explained. None of these is a ranking of importance. They are simply three different starting questions, and the site is arranged so that whichever one you hold points to a coherent chain of pages rather than dropping you into a catalogue.
When to start from a material and when to start from the use case
Start from the material when the appearance is already fixed and the remaining risk is about that stone's behaviour: a designer who has signed off a veined slab needs its vein matching, its sample rule and its panel sequence, not a lecture on where stone can be used. Start from the use case when the constraints are known but the material is not: an exposed stair, a busy entrance or a wet room each eliminate some families before colour is discussed, and the application guides exist to apply those filters. The awkward case is a buyer holding both a fixed stone and a punishing location; there the two routes have to be read against each other, because a favourite block can be exactly wrong for the conditions. If you cannot tell which situation you are in, describe the room and the stone together in the opening message and we will say which door to take first.
Why a mixed-material project is routed as a single written brief
A scheme that calls for a feature marble, an exterior granite and a manufactured worktop is not three small orders; it is one schedule with three material lines, and splitting it into three conversations is where mixed projects go wrong. Separate enquiries produce separate sample approvals, separate interpretations of the same drawing and separate dispatch dates that someone on the buyer's side has to reconcile. They also hide the places where two materials meet: an edge profile or a finish that must line up where the marble stops and the bound surface begins. Routing the whole family list through one written brief keeps a single scope, a single round of sign-offs and one load to plan. It also lets the transitions be designed rather than discovered on site. The brief does not have to be final at this point; it only has to name every family and every surface so nothing is quoted in isolation.
How the stable section pages divide the decision between them
The sections of this site are deliberately stable, and each owns a different kind of question so that no two pages compete to answer the same thing. The material pages settle what is particular to one family: how that stone is selected, what its surface or structure demands, and which sample rule applies. The application pages begin from the use case and carry the constraints that narrow a family shortlist, such as water, exposure and fixing. The capability pages describe work in the order it happens, from an approved drawing through finishing, inspection and packing. The glossary fixes the meaning of a word; the enquiry index routes a short question to the page that owns the full answer. Because every section has one job, a reader can move from a room to a material to a process stage without rereading the same general description at each stop.
Turning a reference image into a shortlist of available blocks
A photograph of a stone you liked is a better first input than a trade name, and not for sentimental reasons. A commercial label gathers material from many blocks quarried at different times, so the name that described a showroom piece last season may point somewhere else now; an image, by contrast, shows the tone, the direction of the veins and the strength of the figure you are actually reacting to. We read those features against the blocks currently on hand and pull a small group of candidates that are genuinely close, then offer physical pieces for approval. The picture is a direction, not a specification, and we will not claim an exact reproduction of natural variation. What it does is compress the search: instead of working through a long list of names, the shortlist starts from the appearance already chosen and narrows by what can be allocated today.
The named fields that make a first enquiry answerable in one reply
A first message is answerable in a single note when it carries a short, fixed set of fields. Name the material or attach the reference image that stands in for it. Say where the surface goes and what it has to withstand, because a floor and a vertical feature are judged differently. State the face you have in mind, or leave it open for us to propose. Say whether the job draws on off-the-shelf formats or a dimensioned drawing, give an approximate sense of volume rather than an exact count, and name the destination, since that decides which records will matter later. Add any document the project will expect at handover. With those lines in front of us the reply can restate the scope, comment on what is available and list what remains to be agreed, instead of opening with a round of questions you have already answered in your head.
When a supply-path decision is declared in a dated routing note
A supply-path decision made over the phone tends to dissolve once a second person joins the project. If an architect picks the material route while an importer later assumes the application route, two briefs can sit in the same inbox, each missing the other's constraints, and nobody has actually contradicted anyone. Request a short routing note naming which door the order entered by, who declared it, and when. That single line settles later arguments when a finish or a drawing shows up belonging to the other path. Without it a supplier can only guess which brief is current, and anything cut from a guess is hard to defend. Put in writing that one contact owns additions, so a corridor remark never becomes scope.
What the echoed scope note must contain before any later document
An entry brief is only useful if the receiving side can prove what it received. Buyers often attach a reference image, a mood board and a typed list, then assume all three were read together; a reply that answers only the typed list leaves the image effectively unacknowledged. Have the scope re-stated back in the supplier's own words, item by item, with each attachment named. Where an item is unclear, it should be listed as open rather than silently dropped. That returned scope becomes the baseline for every later document, including the drawing and the sample register, so a discrepancy is judged against something both sides hold. A brief that was never echoed cannot be appealed to when a crate arrives and the stone reads differently.
Sequencing a mixed brief before workshop instructions are issued
Routing a mixed order works in a fixed order, and reversing it causes avoidable rework. First the family list is written down with the surface each family serves. Next the junctions between those families are named, because a material change at a doorway or a counter edge is where two approvals collide. Then drawings, samples and documents are attached to that same list, so each belongs to a line nobody can disown. Only after the returned scope is signed does cutting get discussed. Designers sometimes release a drawing before the family list is settled, and panels get sized for a stone that is later swapped. Insist the written scope is dated before any workshop instruction, and that a later change gets a fresh date, not the earlier one.
Which records settle a disputed finish after delivery
An entry-route log is worth keeping precisely because most disputes are about memory, not material. When a delivered finish differs from what a buyer recalls approving, the useful question is not who is right but which dated record both sides accepted. A routing note, the echoed scope, and any later revision, kept together, show whether the change was ever declared or simply assumed. Phone calls and site remarks leave no such trail, so they should never be the reference for a re-make. Ask that every amendment be appended rather than edited in place, with the superseded version retained. That habit costs nothing at the start and decides the outcome when a crate is opened and somebody has to say, on paper, what was actually ordered.

Common questions
Questions buyers ask
Do I need to know the exact stone name before I browse this site?
You do not. The site is arranged so that a use case, a process stage or even a rough photograph can be the first input. A room description such as a wet exterior terrace narrows the field through the application pages, and a reference image lets us shortlist available blocks by tone and figure rather than by a label. The exact name usually emerges after that, once a sample set is reviewed. Insisting on a name before you have looked simply delays the step that actually helps, which is finding out what can be allocated.
If my order covers marble, granite and quartz, do I contact three departments?
One contact handles the lot, and that is the whole point of arranging the site this way. A mixed requirement is folded into a single schedule with a distinct line for marble, granite and the manufactured top, all read against one drawing. Run as separate threads, each would generate its own sample round, its own interpretation of a joint detail and its own departure date for the buyer to reconcile later. Worse, the places where two stones meet, a shared edge or a step in level, tend to fall between the threads and get decided by whoever arrives on site first. Keeping everything on one thread lets those hand-offs be drawn deliberately. List every material and every surface in the first note, even if the quantities are still rough; from there the scope is confirmed in one written exchange rather than three.
What belongs in a first message so the reply is complete?
Include the material or a reference image, the application and what it must withstand, the face under consideration, whether pieces come from stock formats or a drawing, an approximate volume, the destination and any record the project will require at handover. Precise counts and final dimensions can follow later. With those fields the opening note can restate the scope, comment on what is currently available and list the decisions still open, so the exchange moves forward instead of circling back to questions already settled.
Who should sign off the first scope note when several people are involved?
One named contact should own the scope on the buyer's side, and the supplier should return a re-stated copy that this contact confirms. When architects, importers and installers each add remarks separately, the written brief stops describing a single order. Ask for the owner's name to be recorded on the note, and for any later addition to arrive through that same contact. A dated confirmation from one person is far easier to trace than several overlapping messages.
Can a phone conversation change what was agreed in the written brief?
A phone call can raise a change, but it should not stand as the record of one. Until the amended point appears in a dated written note that both sides hold, the earlier scope remains the reference. Ask that each amendment be appended with its own date and that the superseded wording be kept, so nobody has to reconstruct a conversation months later. Verbal agreement is quick, but a poor basis for a disputed finish.
