When sourcing natural stone for your projects, the difference between a successful partnership and a costly mistake often comes down to asking the right questions upfront. After years of working with architects, contractors, and distributors across the globe, we’ve identified the most critical areas that deserve your attention before placing an order.
1. How Do Youe Natural Stone Suppliers Verify Quality and Consistency?
Natural stone varies significantly from quarry to quarry, and even within the same quarry. Before committing to a supplier, understand their quality control process:
- Do they provide sample batches from the actual blocks designated for your project? Generic samples may not reflect what you’ll receive.
- What tolerances do they maintain for color variation, veining patterns, and finish quality?
- Can they provide third-party testing certificates for mechanical properties like compressive strength, water absorption, and abrasion resistance?
At Sarhan for Marble & Granite, we maintain rigorous selection standards at the quarry level and provide detailed documentation for every shipment when needed, ensuring what you see is what you get.
2. What’s Included in Pricing from Your Natural Stone Suppliers—and What Isn’t?
Transparent pricing prevents unwelcome surprises. When requested, a righteous supplier will provide pricing differences based on:
- Raw material per square meter
- Finishing and processing (polishing, honing, custom cuts)
- Packaging and crating for international transport
- Shipping logistics, such as Incoterms (FOB, CIF, DDP)
- Import duties and customs clearance (if applicable)
3. What Are Lead Times and Logistics Capabilities of Your Stone Suppliers?
Project timelines depend on reliable delivery. Key questions include:
- What’s the realistic production timeline from deposit payment to containers packing?
- Do you maintain inventory, or is everything made to order?
- What is the trip duration for shipping?
- What happens if there are delays—do you have contingency plans?
Sarhan’s logistics network spans from Egyptian quarries to worldwide ports, with partnerships that ensure smooth customs clearance and on-time delivery to France, Belgium, and beyond.
4. How Do Reputable Natural Stone Suppliers Handle Quality Issues?
Even with the best suppliers, occasional issues arise. Establish clear terms beforehand:
- What’s your inspection and claims process?
- What timeframe do clients have to report problems?
- How do you resolve discrepancies—through replacements, credits, or refunds?
A supplier’s willingness to stand behind their product speaks volumes about their integrity and long-term reliability.
5. Are Your Natural Stone Suppliers Trusted? Can They Provide References from Similar Projects?
Past performance predicts future results. Ask for:
- Client references in your industry (but respect suppliers who value their customers’ confidentiality)
- Past projects of comparable supply in terms stone type, especially if your country has different weather from the source country
- Examples of how they’ve solved complex challenges—custom finishes, tight deadlines, or difficult installations
Speaking with existing clients reveals insights no sales pitch can provide.

Why This Matters
International stone sourcing involves significant investments. A single container of premium marble or granite represent thousands of euros. Getting it right the first time protects your budget, timeline, and reputation with your own customers.
These five questions create a foundation for successful partnerships. They separate suppliers who prioritize your success from those simply moving product.
