Cup burrs are used to round off end points of various sizes of metal, for example on a claw set ring the end of the claw holding the stone is domed, this has been rounded off with this type of burr.This classic claw cluster finisher ensures jewellery will not catch items of clothing when worn. A good example of this is if a customer wears a peg cluster and it has not been finished with a cup burr, when they take off their coat/cardigan it could catch and possibly tear their clothing.
