“We used the Tuscany stone on our new home on our vineyard. We love everything about it. KO Stone provided excellent service. They brought samples to us and they even were able to visit the vineyard when they were in the area. Highly recommend!”

“They were excellent to work with! The stone is exactly what we were looking for, and is our favorite part of the exterior of our house. We would highly recommend!”
Ben E.
“We did a new construction, modern, clean lines in the country. We wanted to balance contemporary but appropriate for the view and landscape. Jeremy is knowledgeable about trends but staying with classic designs. Pricing was comparable to artificial and our masons were happy to work with the KO stones. Now we are doing pool landscape and shopping with them for coping material. Get a bid from them and they’re responsive!”

“Great product and service. Thank you.”
