The details matter

Vein matching for unparalleled precision

We digitally scan every slab and map seam placement before a single cut is made. Many of our layouts use bookmatching, cutting two slabs from the same block and opening them like the pages of a book so the veining mirrors across the seam and reads as one continuous surface.

  • 01Full slab is digitally scanned in our shop before a single cut is made.
  • 02We map seam placement, using bookmatching when the stone calls for it, so the natural pattern reads as one continuous surface.
  • 03You approve the layout on screen before fabrication begins.

Trade & commercial

Built for the people building on our work

Designer concepts and the commercial jobs need a shop that can keep up.

For Designers

Bring us your wildest idea. We work with designers on the projects that don’t fit a standard template, vein matching, custom fabrication, digital scanning and 3D layout planning to bring your vision to life.

For Commercial

Architects, builders, and casework companies come to us for value engineering, full PPE and safety compliance, and fabrication that stays in house from template to install.

Visit us

A showroom built for designers & dreamers

Full slabs on the floor, a conference room for real project meetings, and a team who can walk you or your client through material, layout and budget in one visit.

Bring your plans, your client, or just your questions. This is where the project actually starts.

Trade and designer partners welcome!
