Sea Sediment and Pyrite domed flatback Cabochon, no hole. 40x30mm Sea Sediment and Pyrite. A solid soft mix of earthy and bright colors in splotch mottling as a mosaic stained glass window patterning, with small slivers of shiny pyrite here and there, heavy brecciated jasper. One stone bead. Great to bead around, make into a brooch. Picture is a stock image of the actual stone, which all vary in coloring. I will try to add actual images if you would like a certain one or coloring in particular.
