Clean producer application image with extensive paving surface in foreground, visible blue-grey and brown tonal variation, no watermark or overlaid lettering. Prefer this to the gallery’s pallet images and text-overlaid slab photographs. It is an application photograph, not a calibrated swatch.
Compare the producer’s sample photographs and confirm the current range and finish.
Material sources
Current extraction status is reviewed separately from the portfolio relationship.
Historical permit 1700850 is abandoned. A separate Washington permit, 1700950, is also abandoned and has not been confirmed as its successor. Neither record alone establishes that the currently marketed material is unavailable.
Blue-grey granite from Washington, Maine, offered by J.C. Stone as dimensional building stone and natural ledgestone. These formats belong to one material family.

Known sources; confirm the quarry and selection for your order.
Ask the supplier about current availability, material range, fabrication and test data for your application. A listing or MSHA status does not establish supply readiness.
Material identity, Maine origin and producer quarry relationship follow the named producer pages. Exact site coordinates, current extraction, photographs and laboratory data are verified independently.
