The fundamental difference between granite and quartz lies in their composition. Granite is a 100% natural stone extracted from quarries, meaning every slab has unique aesthetic variations and mineral inclusions. It is porous and requires regular sealing to maintain its integrity. Quartz, conversely, is an engineered composite material typically consisting of approximately 90-93% ground natural quartz mixed with pigments and polymer resins. This manufacturing process creates a non-porous material that does not require sealing and offers more uniform color consistency. While granite is inherently heat-resistant, quartz is designed for high impact resistance and ease of maintenance.

What are the structural differences between granite and quartz countertops?
Granite is a natural igneous rock with high heat resistance and unique mineral patterns. Quartz is an engineered product composed of crushed minerals held together by resin, providing a non-porous, consistent surface that is highly durable and resistant to staining.
