The price of Silestone is comparable to mid- or high-range granite. Granite is more resistant to scratches and high temperatures, but also stains more easily. Both are comparable products, and choices between the two are often based on the homeowner's personal preference.
Granite is taken from the ground and then cut into blocks of stone. These blocks are processed into different types of pieces, such as slabs or tiles, depending on the granite's purpose. Each piece of granite is unique.
Silestone is a quartz product. It's a mixture consisting of 93 percent ground-up granite and quartz, and 7 percent epoxy resin and color pigment. This process makes it less unique than granite.
Due to the process of creating both materials, granite prices vary more than Silestone. Silestone is one of the more expensive quartz products.
Silestone is easier to maintain than granite, as it doesn't require sealing. However, sealing granite is simple and only necessary every three to five years. Silestone is more stain-resistant but less durable than granite due to its plasticity. Granite can handle temperatures up to about 450 degrees Fahrenheit, while Silestone can handle temperatures up to about 300 F.
Granite has more patterns and color variations available. Both have unlimited edge designs.
