Black Diamond Stoneworks was founded in 1997 with the simple belief that quality, value, and performance never go out of style. We started with five cleaning and sealing products for natural stone and ceramic tile. Due to their huge success our product line has continued to grow and now numbers over 20 superior products! Our philosophy to identify a customer’s need and then produce the highest quality product to fulfill that need continues to drive our growth and success. We are so sure that our products will perform as advertised, we offer a “money back satisfaction guarantee” on our entire line. At Black Diamond Stoneworks “We Make Cleaning Easy”.
