NSF Certification for Quartz Countertops

Our quartz countertops are NSF certified, which means they have been tested and meet the highest industry standards for public health protection. NSF certification is the gold standard for food safety, and it ensures that our countertops are safe for direct contact with all food types.

Our countertops are made from a non-porous material that does not allow the growth of surface mold or bacteria. This makes them ideal for use in kitchens and other areas where food is prepared. NSF certification is a valuable assurance that our countertops are safe for your family and your home.

Kosher Certification


Our countertops are specifically designed to meet kosher standards, which allows them to be prepared for Passover and transitioned between dairy and meat usage. This Kosher Certification is an endorsement by a rabbinic agency, affirming that the product’s ingredients, production facility, and the production process itself have been thoroughly inspected. This scrutiny ensures there are no traces of non-kosher substances in either the tools or machinery used in production. The emblem of Kosher Certification guarantees consumers that the product and its production process strictly adhere to all requirements set out by Kosher Law. The process of kashering can be conveniently conducted by pouring water from a ‘kli rishon’ directly onto the countertop surface. This certification reflects our commitment to meeting the diverse needs of our customers.
