Natural Stone Selection

The process of selecting natural stone is a visual and tactile experience. We travel the world in pursuit of the finest natural stones – marble, quartzite, limestone, travertine, granite, and soapstone – hand-selecting and importing distinctive materials of the highest quality.

Our deep-rooted relationships with quarriers and factories in Italy and throughout the world afford us access to luxury materials that are unique in their aesthetics and uncommon in their quality. All of our material is conveniently co-located with our fabrication facility in Watertown, MA to provide a true single source for your natural stone experience.

Stone Design

Our team of experienced Designers and Engineers have rich backgrounds in architecture, interior design, and spatial planning. With natural stone as our medium, we expertly envision and create stunning surfaces that push the boundaries of dimensional stone design.

Your project is unique and deserves personal attention from a trusted professional. You can expect attentive collaboration with a respected stone industry consultant. We’ll ask all of the important questions that will help your vision come to life. From concept drawings through mockups and models, our discovery continues until your vision is accomplished.

Our in-house design team will provide sophisticated shop drawings paired with digital slab renderings, providing the entire project team with a comprehensive and detailed look at the complexity of the work before your project is fabricated.

Stone Fabrication

Since our founding in 1987, our dedication to quality has been of paramount importance. Our state-of-the-art CNC machinery allows us to achieve unmatched fitment and finish, produce technically complex designs and shapes, and produce crisp and precise mitered edges and seams. Our craftsmen, unmatched in skill and artistry and relentless in the perfection of their craft, hand-finish each project with pride. We understand the behavior of natural stone and we meticulously craft it into the surfaces of your imagination.

While many shops still employ outdated fabrication methods like manually cutting slabs or dry-cutting sinks by hand, our commitment to a digital template and fabrication process allows us to operate an efficient, safe, and environmentally-conscious workshop.


A custom fireplace makes a statement unlike any other in a home. We frequently collaborate with New England’s most notable Architects and Interior Designers to produce custom fireplaces of all types, from classic to contemporary, each with a truly unique impact.

Whether spanning multiple stories in a contemporary setting, or accentuating detailed millwork in a classic and refined space, our fireplaces become an integral element of the overall design, creating drama and intrigue. We pride ourselves on our industry-leading capabilities in architectural stonework, using labor intensive and highly skilled fabrication techniques to create a one-of-a-kind fireplace for which there is no substitute.

Tile Installation

A truly remarkable tile installation evokes a feeling of luxury and tranquility. Modern technologies afford mosaicists and artisans the ability to push the boundaries of design with natural stone, glass, ceramic, porcelain, metal, and other media to create incredible works of art that are designed to inspire. While tile is a centuries old medium, the industry is rapidly changing and evolving. A successful tile installation involves so much more than what you see on the finished surface.

Our team of in-house tile installers are experts in the technical aspects of tile installation.
