I dont have access to up-to-date pricing information, as those prices may vary depending on region, quality, supplier, and other factors. However, generally speaking, granite is more expensive than basalt because of its scarcity, durability, and aesthetic appeal. Basalt is also a durable and heat-resistant material, but its less common and less sought after for use in kitchen countertops. Ultimately, the cost of either material will depend on various factors, such as the size of the countertop, installation costs, and quality of the material. Its recommended that you compare prices from various suppliers and factor in all the costs involved before making a decision.
