Deer Isle® Granite

Deer Isle® granite, quarried in Maine, is a durable natural stone known for its classic color palette of pink/mauve, gray, and white with black mica flecks. This granite's coarse grain makes it ideal for both interior and exterior uses such as countertops, flooring, facades, and landscape items. Deer Isle®'s appearance is versatile by use of different finishes including polished, honed, thermal, and leathered, as well as historic finishes such as pointed, bush-hammered, and six-cut which enhances its suitability for diverse architectural applications. This material's longevity and classic appearance have made it a top choice for notable landmarks and design projects including the Boston Museum of Fine Arts, the Brooklyn Bridge, and Rockefeller Center in New York City, and the Conrad Hilton in Chicago to name a few.

Quarried off the coast of Stonington, Maine, Deer Isle® granite has been a prized material since the 19th century, contributing to landmark projects across the Eastern U.S., especially in cities like Boston, New York, and Washington, D.C. While many quarries from that era have ceased operations, Deer Isle® granite remains in demand today due to its superior quality and timeless, crisp appearance. Its enduring popularity highlights its suitability for a range of architectural and design applications, both historic and modern.
