As a jewellery nut and reader of jewellery making techniques, I
always scrutinise any jewellery that crosses my path. Having read a
lot about prong setting, with instructions to cut/file notches for a
stone’s girdle to sit in (but no more than a third of the prong’s
thickness), I have noticed that the vast majority of prong set
stones are not notched at all. The prongs on virtually all the
jewellery I’ve handled, have the whole prong width retained, and
each prong is just bent inwards to “secure” the stone. This looks
very insecure as far as I can tell.
Does anybody know why some jewellers make notches and others don’t?
To notchor not to notch? That is the question ;-). I want to take
the plunge and attempt prong setting again, but I’m interested in
the different techniques.
