serpentine Black and Green Slab with light Schiller Effect

serpentine Black and Green Slab with light Schiller Effect. Found on the middle Yuba River. There is a lot of serpentine in this area yet this specimen will not scratch with a knife blade. Measures about 5.75" x 3.75" x .261" Thick or 6.64MM Thick. Weighs about 8.3 Oz. I see a potential crack towards center yet great cabs can still be made.Photographed wet and slabs are at an angle to stop some glare so slabs in pictures look smaller. You cannot see the Schiller Effect in the pictures.
