I'm going to try the email all option and share this technique, welcome 2 new users btw. This is a great way for heat sensitive stones and it takes less time than the usual using a pick and waiting to get enough heat around your joint. Notice that it soldered before the wet paper started sizzling. Also my torch was pointing upwards so be careful of what behind your ring. I had already inserted a piece of chip solder in the joint as well and fluxed. Another way to do this is submerging the heat sensitive stone in water within a cap full while you solder. The. There's the heat paste which is a mess but works. You don't want to use too much water where the steam is interfering with your flame or your paste got near your joint flame path.
