Does anybody know why some jewellers make notches and others
The correct technique is to notch. Technique of bending prongs is
the result of sub-contracting. To allow for notching, prong should be
relatively thick and long.
After setting the excess is clipped off. However, if job done by
outside contractors, the clippings stay with setter. When gold was
$300 it was acceptable, but when gold started to climb, the practice
became very costly. So the prongs became very thin and short.
The only way to set them is to bend around girdles.
