Cut natural stone such as marble or granite is provided with spaced apart oppositely inclined circular saw cuts from the interiorly exposed surface to and toward but not through the exterior exposed weather surface. The cuts are made preferably towards one another without relative movement of the saw along the plane of the stone panel so as to leave a circular profile at the bottom of each inclined cut. First and second planar clamp sections are inserted to fit within each cut, the clamp sections having a complementary curved and arcuate profile penetrating the curved and arcuate profile of the saw cut. The clamp sections are each prebent so as to expose elongate back to back mounting sections in juxtaposition disposed generally parallel to the interior surface of the stone. Typically the mounting sections on one clamp portion overlies and is configured for welding to the mounting portion of the other clamp section. Such configuration can include one mounting section being narrower than the other mounting section for a butt weld or one mounting section provided with holes for a plug weld. When the sections are fastened, the clamp is locked to the stone. A process of constructing a natural stone curtain wall is disclosed in which natural stone panels are placed in their desired spaced apart relationship, typically in a jig. Clamps are mounted as desired in accordance with this invention and thereafter a supporting frame lowered and braced in spaced apart relation above the stone panel and attached clamps. Connections between the elongate clamp backs and the frame are made so that when the frame is lifted free, the exterior weather surface of the stone is supported from the frame.
