Does the color of Silestone affect its price?

Color does not significantly affect the price of Silestone countertops, but instead it varies based on thickness and grade quality. As of 2015, the average cost of a Silestone countertop ranges from $50 to $100 per square foot. This average does not include the cost of installation.

Countertop edge details range from $15 to $30, based on the design. Silestone is a man-made stone created from a mix of crushed quartz, polyester resin and polymers. Brands of Silestone include Ceasarstone, Cambria, Dupont Zodiaq and Okite. Excluding diamonds and sapphires, the quartz surface is made from one of the hardest minerals. This makes Silestone countertops durable and resistant to cracks.
