It seems that if you ask 10 jewelers what is the proper way to
measure a triangle cut gem stone, 5 will say “point to point” and 5
will say “flat to point.”. There doesn’t seem to be a consensus among
jewelers, casters and stone cutters. And as you well know, if the
stone is measured side to point and the setting is measured point to
point, or visa versa, it sometimes doesn’t work very well. How does
everyone out there measure these stones? What’s your preference?
