How to Get a Granite Sample from an Indian Supplier — What to Ask For and What to Expect
Most UK masons and French marbriers who are serious about getting a granite sample from an Indian supplier know they should request one before placing a production order. What stops them is not scepticism — it is uncertainty. They are not sure exactly what to ask for, what the sample will cost, how long it takes to arrive, or what they are supposed to evaluate when it gets there. This blog removes every one of those uncertainties. The sample process with an Indian granite supplier is straightforward when you know the protocol: what to specify, what to ask alongside the physical piece, what a legitimate supplier provides for free, and what to do if the sample does not meet your standard. By the end of this guide, you will know exactly how to initiate the process and what to expect at each stage.
Quick Answer
Request a polished sample of approximately 30×20 cm, in the specific granite variety and grade you intend to order — premium grade, mirror polish, engraving-ready surface. A serious supplier provides the sample free of charge; you pay shipping only, typically £15–£40 from India to the UK by international courier. Allow 7–14 days from despatch. Ask for written confirmation of grade, origin, and polishing process alongside the physical piece — not just the stone itself.
What Exactly to Ask For
The most common mistake in a first sample request is being too vague. “Can you send me a sample?” gives the supplier nothing to work with. They will send whatever they have to hand — which may be a rough offcut, an unpolished slab piece, or a tile-grade sample that tells you nothing about the quality of a production headstone blank. Your sample request needs to be a specification, not a question.
The physical specification
Ask for a polished piece, approximately 30 cm × 20 cm. This size matters. A piece smaller than 20 × 15 cm does not give you enough surface area to assess tonal uniformity, check for inclusions at the edges, or run a meaningful engraving test. Thirty by twenty centimetres is the minimum at which you can do all three properly. Larger is fine — up to 30 × 30 cm is common — but 30 × 20 cm is the practical floor.
Specify the thickness. For an Absolute Black headstone blank evaluation, ask for the sample to be cut to 20–30 mm thickness — thin enough to be shipped economically, thick enough that the polish depth on the face is representative of a production piece. A sample cut too thin may not accurately represent how the mirror finish behaves on a 100 mm headstone blank.
Grade and finish
State explicitly: premium grade, mirror polish, laser engraving-ready surface. These three descriptors communicate the production standard you intend to order to. A supplier who sends a standard-grade or commercial-grade sample — whether deliberately or through misunderstanding — has given you no useful information about their premium output. If the sample arrives and the polish is uneven or the grade is visibly lower than premium, that is itself a piece of information. But make sure you asked for the right thing first.
Variety and origin
Name the variety precisely — Absolute Black (Karnataka, Hassan district) or Tan Brown (Andhra Pradesh), not “black granite” or “brown granite.” The origin specification matters because the same variety name can cover stone from different quarry zones with different quality profiles.

What a Legitimate Supplier Provides for Free
A serious, established Indian granite exporter provides the sample piece itself at no charge. This is standard practice across the export industry. The supplier’s cost to cut and polish a 30 × 20 cm piece is minimal — it is a cost of doing business and an investment in the relationship. If a supplier quotes you a charge for the sample piece itself, it is a signal either that they are not export-oriented or that they are filtering out buyers who are not serious. You should not pay for the stone.
What you do pay is the international courier shipping cost — typically £15 to £40 from India to a UK address, depending on the size and weight of the piece and the courier service used. DHL, FedEx, and UPS all operate direct India-to-UK express services. Your supplier will either invoice you for the shipping cost or ask you to provide your courier account number if you have one. A 30 × 20 × 2 cm granite piece weighs approximately 3–4 kg — light enough to ship economically by courier without customs complications.
How Long It Takes
Once your supplier has despatched the sample by international express courier, allow 7 to 14 working days for delivery to a UK address. In practice, DHL and FedEx from major Indian cities to UK destinations typically deliver in 5–7 working days. The variability comes from customs clearance — stone samples are subject to standard import procedures, and occasional delays at UK customs are possible, though rare for small courier shipments.
The timeline before despatch depends on the supplier. If they have polished samples already prepared — as most established exporters do — they can ship within two to three working days of your request. If they need to cut and polish a piece specifically for you, add a week. Ask your supplier when they expect to despatch and request a tracking number when they do. A supplier who cannot provide a tracking number for a courier shipment is not operating at a professional export level.
What to Ask Alongside the Physical Sample
The sample stone is only half of what you need. The other half is written documentation. Request the following in writing at the time you ask for the sample — not as an afterthought after it arrives.
Written confirmation of grade and origin
Ask for a written statement confirming: the granite variety and commercial name, the quarry district and state of origin, and the quality grade classification used by their factory (Premium / Grade A, or equivalent). A supplier who cannot or will not put these in writing is a supplier you should be cautious about. The written statement becomes part of your supplier evaluation file and the basis against which you compare the physical sample.
Polishing process details
Ask how many polishing steps the sample has gone through. For a mirror polish to laser engraving standard, the answer should be a minimum of eight to ten progressive abrasive steps. A supplier who cannot tell you their polishing stage count is either not producing to that standard or does not manage their process closely enough to know. Neither is reassuring.
Block reference locking process
Ask the supplier to explain their process for block reference locking on a production order. This means: how do they ensure that the production pieces you receive match the sample you approved in terms of colour, grain, and tonal depth? The answer should be that they identify the specific block or quarry run used for your sample, reserve material from the same extraction for your production order, and confirm this in writing when you place the order. If their answer is vague — “we always use the same grade” — ask specifically how they control this. Tonal consistency between the sample and the production delivery is one of the most common failure points in Indian granite supply.
What to Do When the Sample Arrives
When the sample lands, resist the temptation to form an immediate impression from a quick look. Evaluate it systematically. Our complete granite sample evaluation checklist covers every test you should run — colour assessment under different lighting conditions, surface haze detection, polish depth verification, edge quality, and a small-area engraving test if you have the equipment. Work through that checklist before forming your view.
Two specific checks that often reveal a supplier’s actual production standard: examine the edges of the sample under raking light — any micro-chipping or roughness at the arris indicates the finishing stage was not completed properly. And photograph the face under direct overhead light as well as under angled light at approximately 30 degrees. A surface haze that is invisible under direct light often shows clearly under raking light. A production mirror polish at engraving quality should be clean under both.
What to Do After Evaluation — Pass or Fail
If the sample passes your evaluation on all criteria, the next step is a formal quotation request. Send the supplier your complete written specification — dimensions, grade, finish, quantities, packing requirements — and ask for a Proforma Invoice. Do not place an order on a verbal quote. The written Proforma is your price lock and specification confirmation.
If the sample does not pass
Give specific, technical feedback rather than a general “not good enough.” For example: “The face shows a light haze under raking light that would be visible after laser engraving — the polish needs to be deeper” or “The stone has a slight blue undertone under daylight — please confirm this is consistent with your premium grade, as our expectation is neutral black.” Specific feedback gives the supplier something to act on and shows that you know what you are looking for — which in itself improves the quality of what they send next. Most established exporters will offer to send a second, corrected sample at no additional charge if the first sample was genuinely below the requested standard.
Frequently Asked Questions
Will every Indian granite supplier send a free sample?
Established exporters who work regularly with UK and European trade buyers will provide the sample piece free of charge as standard practice. Smaller domestic-market suppliers or newer-to-export operations may charge for the sample stone itself. As a general rule, if a supplier quotes a fee for a polished sample piece — as distinct from the courier shipping cost — they are not operating at the export standard you need. The shipping cost is always the buyer’s responsibility.
Can I request samples of more than one variety at the same time?
Yes, and for a first evaluation it is often sensible to request Absolute Black and Tan Brown in the same courier shipment if you work with both varieties. Two 30 × 20 cm pieces can be shipped together in a single box, keeping the shipping cost close to what a single piece would cost. Ask your supplier explicitly — “Can you include a sample of both varieties in the same shipment?” — rather than placing two separate requests, which may result in two separate courier charges.
What if the sample arrives damaged?
A polished granite sample shipped in a properly padded courier box very rarely arrives broken, but it does happen. Photograph the packaging before opening it, and photograph any damage to the piece immediately. Notify the supplier in writing with photographs the same day. A professional supplier will arrange a replacement sample at their cost for a shipment that arrived damaged through inadequate packing. If the damage is clearly caused by the courier rather than the packaging, raise a claim with the courier directly — most express courier services include basic damage insurance on international shipments.
Should I test the sample for laser engraving before placing a production order?
Yes, if you have access to a laser engraving machine — or a colleague who does. A small test engrave on a corner of the sample is the most reliable way to confirm that the polish depth and surface homogeneity meet your engraving standard. Run a simple text line or motif at your normal engraving settings. The engraved area should produce a clean, consistent white contrast against the black surface without ghost marks or uneven burn depth. If the engraving result is inconsistent, it points to either polish quality or surface mineral variation — both of which need to be resolved before you place a production order.
