Common questions
What is found.rocks?
found.rocks is an independent reference site for natural stone. It combines a Stone Library (profiles of named regional stones), a directory of verified fabricators, stonemasons, and quarriers, an AI-assisted Identify-a-Rock tool, and a journal of buyer-intent guides on cost, sourcing, and project planning. The US, UK, and Ireland sections share the same editorial standards.
Which US stones does found.rocks cover?
Pennsylvania Bluestone, Tennessee Crab Orchard, Vermont Slate and Marble, Indiana Limestone, Texas Lueders, Connecticut Brownstone, Arizona Flagstone, California Sierra White, New York Bluestone, and Georgia Marble. Each named stone has a full geological and commercial profile in the Stone Library, and most are referenced in regional cost guides for patios, countertops, cladding, and stonework.
How are US listings verified?
A business earns the Verified badge only when it appears on the Natural Stone Institute's published Accredited Company list. Verification is independent of payment and independent of how the listing was sourced. State geological surveys, the Indiana Limestone Institute, and regional masonry institutes are being reviewed as additional sources. See /us/verification for the full policy.
Are directory listings paid?
No. The directory ranks by relevance and verification status, not by who is paying.
