Granite is one of the most popular natural stones used for flooring, kitchen countertops, wall cladding, staircases, and outdoor applications across India and Asia-Pacific countries. Its durability, strength, and timeless appearance make it a long-term investment. However, not all granite available in the market is of the same quality.
Before purchasing granite for your home or commercial project, it is essential to understand how to check the quality of granite to avoid cracks, discoloration, or early damage. This blog will help you make the right choice with confidence.
Why Granite Quality Matters ?
Granite is a natural stone formed under extreme pressure, but variations in mineral composition, quarrying methods, and processing quality can significantly impact its performance. Low-quality granite may absorb water, stain easily, crack under pressure, or lose its shine over time.
Choosing premium-quality granite ensures:
- Long-lasting durability
- Better resistance to stains and heat
- Consistent color and texture
- Higher value for money
At World of Stones India, granite is sourced and processed with strict quality checks, making it suitable for Indian and Asia-Pacific weather conditions.
1. Check the Granite Surface Finish
The surface finish tells a lot about granite quality. A good-quality granite slab should have a smooth, even finish without rough patches or uneven polish.
Run your hand over the surface. If the granite feels grainy or patchy, it may not be properly polished. High-quality granite has a uniform shine and does not appear dull in certain areas. Polished granite is ideal for interiors, while honed or flamed finishes are better for outdoor and high-traffic areas in India.
2. Inspect the Color Consistency and Patterns
Granite is a natural stone, so slight variations are normal. However, extreme color inconsistency may indicate poor-quality stone or artificial treatment.
Look at multiple slabs from the same batch. The base color and grain pattern should be consistent. Sudden discoloration, faded spots, or irregular blotches can mean the stone is either dyed or unevenly processed. Premium granite from trusted suppliers like World of Stones India maintains natural color stability across slabs.
3. Perform the Water Absorption Test
Water absorption is one of the most important indicators of granite quality, especially in humid regions like India and Southeast Asia.
Place a few drops of water on the granite surface and leave it for 10–15 minutes. If the water is absorbed quickly and leaves a dark patch, the granite is porous and of lower quality. High-quality granite absorbs water very slowly or not at all. Low porosity means better resistance to stains and moisture, making the granite suitable for kitchens, bathrooms, and outdoor areas.

4. Check Granite Thickness and Strength
Granite thickness plays a crucial role in its durability. In India, standard granite thickness ranges from 16 mm to 20 mm for flooring and countertops. Thin granite slabs may crack easily under pressure or heavy loads. Always ask for the slab thickness and ensure it matches your application needs.
Quality granite slabs from world of stones india are processed with proper thickness to meet both residential and commercial standards.
5. Test for Scratch Resistance
Granite is known for its hardness, but not all granite types offer the same scratch resistance.
Use a metal key or coin to gently scratch an unseen corner of the slab. High-quality granite will not show scratch marks easily. If visible scratches appear, the granite may contain softer minerals and may not be ideal for heavy-use areas. This test is especially important for kitchen countertops and flooring.
6. Check for Cracks, Fissures, and Resin Filling
Natural granite may have fissures, which are different from cracks. Fissures are naturally occurring and usually filled during processing, while cracks weaken the stone.
Inspect the slab closely under good lighting. Avoid granite with visible cracks or excessive resin filling, as this reduces strength and lifespan. Reputed suppliers like World of Stones India ensure proper inspection and quality control before supplying granite slabs.
7. Verify Granite Density and Weight
High-quality granite is dense and heavy. If two slabs of the same size are available, the heavier one usually indicates better density and strength.
Low-density granite may break easily and is more prone to chipping. Density also affects heat and impact resistance, which is important for Indian kitchens and commercial spaces.
8. Check the Backside of the Granite Slab
The backside of the slab reveals hidden quality issues. A good granite slab has a relatively smooth back with uniform texture.
If the backside looks extremely rough, flaky, or uneven, it may indicate weak stone composition or poor cutting techniques.
9. Ask About the Granite Origin
The source of granite matters. Indian granite is widely known for its strength and durability, while some imported granites may be softer.
Granite from trusted quarries and manufacturers ensures better performance. We supply high-quality granite suitable for Indian and Asia-Pacific usage conditions.
10. Ensure Proper Sealing and Finishing
Even premium granite requires sealing for enhanced stain resistance. Ask whether the granite is pre-sealed or needs sealing after installation.
Proper sealing protects granite from oil, water, and chemical stains, which is especially important in Indian households.

Common Mistakes to Avoid When Buying Granite
One of the biggest mistakes buyers make when purchasing granite is choosing the stone only based on appearance. While color and pattern are important, granite quality depends more on factors like density, porosity, thickness, and finish. A visually appealing slab may still absorb water, stain easily, or crack under pressure if its internal structure is weak. Always inspect the physical quality before making a decision.
Another common error is ignoring the water absorption test. Many buyers assume all granite is non-porous, which is not true. Poor-quality granite absorbs water quickly, leading to stains and moisture damage especially in humid climates like India and Southeast Asia. Testing water absorption before buying helps avoid long-term maintenance issues.
Buyers often overlook granite thickness, especially when choosing cheaper options. Thin granite slabs may look fine initially but can crack or break over time when used for flooring, staircases, or kitchen countertops. Always ensure the granite thickness matches the application and complies with industry standards.
Choosing granite without checking for cracks or excessive resin filling is another major mistake. Natural fissures are normal, but visible cracks weaken the stone. Excessive resin filling may hide defects temporarily but reduces durability in the long run. Proper inspection under good lighting is essential.
Many people also fail to consider where the granite will be used. Granite suitable for indoor flooring may not perform well outdoors. Similarly, polished granite may become slippery in wet areas. Selecting granite without understanding its application can lead to safety and performance issues.
Finally, buying granite from unverified or low-cost suppliers can result in inconsistent quality and poor after-sales support. Trusted suppliers like World of Stones India follow strict quality checks and provide stones suited for Indian and Asia-Pacific conditions, ensuring durability and peace of mind.
Conclusion
Buying granite is a long-term investment, and knowing how to check the quality of granite before buying helps you make the right choice. From surface finish and water absorption to thickness and origin, each factor plays a crucial role in determining granite quality.
