About Granite
Granite is an igneous rock formed from slowly cooling magma deep beneath the Earth's surface. Composed primarily of quartz, feldspar, and mica, it is one of the hardest and most durable natural stones available. Its crystalline structure gives it a distinctive speckled appearance and exceptional resistance to scratching and chemical damage.
With a Mohs hardness of 6-7, granite is highly resistant to daily wear and even tolerates acidic substances without damage - a key advantage over marble. It is also heat-resistant, making it ideal for kitchen countertops where hot pans may be placed directly on the surface.
Granite's low porosity means it absorbs very little moisture, though it should still be sealed for optimal stain resistance in kitchen environments. It is frost-resistant, making it equally suitable for outdoor applications like terraces, facades, and garden paths. Available in hundreds of colours and patterns from quarries worldwide, granite offers both durability and design versatility.
