Since 1992, AG&M has been a worldwide leader in natural stone supply, including granite, marble, quartzite, and soapstone. We have 9 U.S. sales centers with slab yards and a globetrotting management team that is dedicated to bringing the finest selection of slabs and surfaces to your door. Our deep industry experience and excellent reputation give us access to the finest quarries in the world, with the buying power to bring our customers top-quality natural stone at an economical price.

While AG&M is a wholesale distributor, our showrooms are open to the public from Monday to Saturday. Our talented and friendly staff is ready to help you select the ideal stone and tile for your project. No appointment necessary.

The AG&M Experience
Visit one of our 10 beautiful AG&M showrooms to explore our products and get inspired.
Bring in any available swatches, samples, or design materials to assist in the selection process. Our knowledgeable design team is always available to answer questions and help with your selection.
After hand-selecting slabs or materials, AG&M will happily place a hold on the material. At this point, your fabricator will take over to finalize details, purchase the material, and begin installation. Please note that we do not sell directly to the public.


AG&M prides itself on its extensive, globally sourced collection of natural stone and quartz slabs. We carry more than 120 colors of natural stone in slabs from Brazil, India, Italy, Europe, and beyond. Our premium quartz offering, MetroQuartz, is also available in an array of designer-inspired colors; it offers the beauty and feel of natural stone with the performance and design versatility of an engineered product.
