For starters you can look for stones with Pavillion angle lower than 41°. It brings you within the safe territory.Shelley9 said:Thanks everyone. Why would it have leakage under the table? What are the parameters to use to avoid this or is leakage nothing to do with the parameters? Still learning. Thankyou again for your help. Any other stones you would recommend? I have found a couple on Jogia but they charge $200 to call the stone in for further investigations, pictures.
