Circe: would you be able to let me know if all (3 on all 4 sides?prongs are holding your stone? I managed to print it and took it in and he said only two would be holding it and the 3 prong is just there decorative? He said it would put lots of pressure on the stone if it was held with all 3 . I can''t really see from the pic if all have contact with the stone or not? Thanks
