Both these materials are beautiful and strong and have been used throughout the years by the building industry and interior designers alike. However, the main difference between granite and quartz is that granite is a natural material, whereas quartz is a manmade material.
Although granite is tough, it's also porous and requires sealing on an annual basis to ensure its quality. If left unsealed, your granite surface becomes prone to bacteria, making it an unhygienic surface for your kitchen. Granite is a beautiful material but it has natural flaws that can, unfortunately, result in chips and cracks. Quartz, on the other hand, is a highly durable, non-porous surface that is resistant to scratches, chips, stains and heat, and is a low-maintenance material that can be easily cleaned with warm water and soap. A Caesarstone quartz surface will never require any sealing.
Another benefit of choosing quartz for your kitchen is that this manmade material doesn’t include the drawbacks of some natural stones. For example, due to the manufacturing process of quartz, you can design your worktop to look like granite or other surfaces, such as concrete, without having to suffer the porous nature of these natural materials.
