This Bezel setting tool won't scratch the bezel like a steel bezel pusher. If you slip while setting a stone, it's no big deal, no damage to the stone. The 3d printed high-impact biodegratable plastic prevents damage to the stone and in the event of a stone-destroying slip of the hand. This stone-setting Bezel Pusher was designed to make setting a cabochon on pendants and rings easier and less painful for users suffering from hand and wrist issues. After testing in the field, we found that non-suffering users love the ability to hold the setting firmly while rotating it for easier positioning of the hand and bezel tool. They also love that if you do slip, you don't mar the bezel or the stone! This bezel pusher is included in our Stone and Bezel Setting Tool Kit. In that kit, your pendant or ring is secured when it is pressed into the mounting plastic that has been heated with a heat gun or high-temperature hair dryer. The mount is rotated with the non-dominant hand to bring the bezel into different positions. The bezel is easy to work on, with the ergonomic bezel pusher that is in the palm of the hand or held in the fist. Once the stone is secured in the bezel, the ergonomic bezel burnisher is used to harden and polish the edge of the bezel. Once the bezel is closed, the assembly is lightly heated to remove it from the rotating mount
