About Us

It our pleasure to share with you a brief description of our company and distinguishing details that set us apart from other stone suppliers, vendors and merchants.

NSI Stone Trading has been in business for more than two decades and is one of the leading national suppliers of natural stones. Over these years, we have established a strong trust and confidence of being a reputable and a highly recommended importer and supplier in the industry. Our warehouse in Brooklyn, New York carries over 2 million square feet of carefully selected slabs of marble, granite, quartzite, limestones, travertine, terrazzo and other natural stones. In addition, our showroom showcases a vast variety of porcelain, ceramic, glass, and metal tiles and mosaics.


As a company, we regard the overall satisfaction of all our customers as a top priority, from the first point of contact until the stones are safely unloaded at their destination. We confidently assert that we have "the" sales team who possesses extensive knowledge of a natural stone's physical characteristics, its strength and suggested uses - even the minor nuances between stones of the same kind. This is the sales team who truly gives careful attention to every detail of our client's needs.
