A stone store is worth choosing only when it can connect the material on display to the material you will receive, install, and maintain. Use the checks below to compare suppliers on stock, stone performance, fabrication, delivery, and accountability before you pay a deposit.
Key takeaways
- Ask which stones are in stock and what services the store handles.
- Inspect the actual slabs and record their origin, type and identification details.
- Choose stone for the room’s use, moisture and maintenance demands.
- Compare fabrication, installation, delivery and after-sales terms in writing.
Start With a Store-Selection Checklist Before You Visit
A credible natural stone store should answer basic questions before you make a showroom visit: what it keeps in stock, where its stone comes from, and which services it handles. Use this checklist by phone or email.
1. Confirm that the store carries the material you need. Ask a marble supplier or granite dealer for current stock, available colours, slab or tile sizes, thicknesses, finishes, and expected replenishment dates.
2. Ask for the stone’s commercial name, quarry or source, and supplier identification. Treat “granite,” “marble,” and “Kota stone” as categories, not performance grades; two lots with the same name can differ in absorption, strength, porosity, and stain resistance.
3. Request photographs of full slabs from the current lot, not only small display pieces. Ask whether the photographs show actual stock and whether you can inspect the slabs before cutting.
4. Ask for test reports tied to the quarry, block, or production lot being supplied. A certificate for another source or batch does not prove your stone’s performance.
5. Confirm fabrication capability before requesting a quote: cutting, sink and hob cut-outs, edge profiles, stair nosing, skirting, polishing, sealing, transport, lifting, and installation.
6. Require the quotation to separate stone rate, thickness, finish, usable area, wastage, labour, delivery, GST, and installation. If the store cannot define these items, its low square-foot rate is not a reliable comparison.
Inspect the Actual Slabs and Prove Their Identity
A small sample cannot prove that the delivered stone will look the same. Arrange a full slab inspection before cutting, preferably viewing slabs from the same lot, because stone colour variation, veining, fossil content, open grains and background shade can change across one slab.
Before approving the material, record these identifiers and conditions:
- Slab tag, bundle number, quarry or source, lot number and measured length, width and thickness
- Clear photographs of each slab, including the tag, full face and close-ups of veining, cracks, repaired fissures and resin-filled pits
- Dry, well-lit inspection results for edge damage, bowing, shade mismatch and inconsistent polish or other finish
- The actual nominal thickness and permitted variation stated on the quotation or invoice, not merely “premium slab”
Match the tag and photographs with the slabs loaded for dispatch. A test certificate for another quarry, block or production lot does not prove the delivered material; ask for a report linked to the supplied batch and stone variety. Inspect again before accepting delivery, while the slabs remain dry and uncut.
After cutting or installation, a pre-existing fissure can be mistaken for fabrication or site damage, making responsibility difficult to establish.
Match Stone Performance to the Room, Not Just the Look
Choose the stone by the room’s stresses: water, abrasion, acids, impact, sunlight, and load—not by showroom colour alone. “Marble,” “granite,” and “Kota stone” are commercial categories, not performance grades; compare absorption, flexural strength, hardness, and stain or weathering resistance for the actual quarry and supplied lot.
| Material or alternative | Strengths | Check before choosing |
|---|---|---|
| Marble | Veining and a polished finish suit living areas, walls, and low-abrasion floors | Acid etching, scratches, staining, absorption, and maintenance; marble vs granite is not a simple quality ranking |
| Granite | Hard surface for kitchen counters, stairs, entrances, and heavy traffic | Water absorption, resin-filled pits, slab thickness, edge support, and the report for the delivered lot |
| Kota stone | Limestone with green, blue, brown, and related shades; practical for floors and steps | Quarry and lot variation, porosity, finish, thickness, and slip performance |
| Slate or sandstone | Textured surfaces for floors, walls, balconies, and landscape features | Flaking, uneven thickness, water absorption, salt weathering, and cleaning method |
| Decorative stone or alternative tile | Useful where appearance, weight, or budget matters more than solid-stone performance | Confirm UV stability, wet slip rating, impact resistance, repairs, and replacement availability |
For bathrooms, balconies, and entrances, assess the complete floor system: waterproofing, slope to the drain, joints, grout, and wet slip resistance. A rough surface will not fix ponding water or failed waterproofing.
Treat sealing as spill-response time, not stain-proofing. Put the actual nominal thickness and permitted variation on the invoice; an 18–20 mm slab, thin tile, and stair piece require different support and edge details. Ask for test data tied to the supplied batch, not another quarry or block.
Compare the Complete Quote, Fabrication and Installation Plan
A lower per-square-foot rate can still produce a higher installed bill. Ask each stone store to quote the same measured area and disclose these items separately.
| Comparison point | What to verify | Why it changes the result |
|---|---|---|
| Stone and wastage | Stone name, lot, quantity, unit rate, and wastage allowance | Veined slabs and complex layouts create more cutting waste |
| Stone thickness | Actual nominal thickness and permitted variation | A 18–20 mm slab, thin tile, and thick stair piece need different support and handling |
| Stone finish | Polished, honed, leathered, flamed, or another named finish | Finish affects appearance, maintenance, and wet slip performance |
| Stone fabrication | Cutting, sink and hob cut-outs, joints, drilling, and polishing | Unpriced work appears later as fabrication charges |
| Edge profiles | Bullnose, pencil, bevel, ogee, or square edge, with running length | Detailed edges take more machining and alter the finished dimensions |
| Installation | Substrate preparation, adhesive or mortar, full bedding, levelling, joints, and labour | Spot-bonding large pieces leaves voids that increase cracking risk |
| Extras | Transport, lifting, skirting, stair nosing, sealer or sealant, GST, and site protection | Omissions make two apparently similar quotes incomparable |
For bathrooms, balconies, and entrances, require the installation plan to show slope to drain, waterproofing, grout, movement or perimeter joints, and the wet-area slip requirement. A rough finish cannot correct ponding water or failed waterproofing.
Ask Nakoda Marble, or any competing store, to attach the slab layout, fabrication drawing, and installation exclusions to the quotation before you pay an advance.

Check Delivery, Acceptance and After-Sales Responsibility
Before stone delivery, record the approved slab or bundle numbers, dimensions, nominal thickness, stone source, finish, and photographs of the actual material. Take these photographs while the slabs are dry, clean, and well lit, before cutting or installation hides defects.
- Match every delivered slab or bundle to the recorded tag and invoice. The invoice must state the actual nominal thickness and permitted variation, not simply “premium slab.”
- Inspect for cracks, repaired fissures, resin-filled pits, open grains, edge damage, bowing, shade mismatch, and inconsistent polishing. Note each defect on the delivery receipt before signing.
- Confirm that any test report identifies the same stone variety, quarry or source, and production lot. A certificate from another block or batch does not prove the delivered material.
- Ask the store to state its breakage responsibility in writing, including who pays for damage found during unloading and how quickly replacement availability will be confirmed.
- Keep the delivery receipt, photographs, slab tags, approved layout, and complaint contact together. Once cutting begins, separating a pre-existing defect from fabrication or site damage becomes difficult.
Reliable after-sales support includes a named contact, a defined inspection period, prompt site assessment, and a written decision on repair, replacement, or credit. Confirm whether replacement material will match the original shade and lot; a different batch can look visibly different even under the same stone name.
