well now i have more faceters using my polishing method, so much, that the historian for the USFG, Jeff Theesfeld, has posted his experience with it in the dec 2023 news letter. i have numerous more faceters now using my way. preferably a tin lap hopefully 98+ % tin alloy and a good grade of 50,000 grit diamond powder/.5micro, SLOW lap speed and SLOW water drip. and we go from a coarse shaping grit to a 1200 final cutting grit and then the tin and 50k finish on all stones and hardnesses. been faceting for 59 years.
