Hi. This stone was a bear. We went from 200-3000 grit. It would not respond to 5x. When we started working on it,  it was thoroughly etched after 20 years, but no scratches to speak of. Amazingly hard. Does anyone know what this is?  It responds like serpentine but no veins, only white dots and rings.
