I do not have access to real-time pricing information. However, Nevsehir Pumice is a volcanic rock type produced in the Nevsehir region of Turkey and it is often used in construction and landscaping due to its lightweight, porous and insulating properties. The cost of the stone may vary depending on factors such as the quality, size and availability. It is recommended to contact local suppliers or consult with a professional to inquire about the current pricing.
