Soak all rough stones for 15 minutes or more before use.


  • Please do not soak finishing stones (#3000 and above). Soaking a finishing stone will result in the stone cracking and breaking.
  • Returning a stone into a box while still wet or damp will result in molding and decreasing quality.
  • For double sided stone, please only soak the medium stone side (#1000). Failure to do so will result in the stone splitting and or breaking.
