STEEL TAPERED RING MANDREL WITH GROOVE
A to Z, 1 to 6 MARKINGS
290mm (11.5") Length
Made of hardened steel and used for re-sizing rings. Sometimes a large faceted stone may be mounted in a ring so that the cutlet of the stone intrudes on the finger hole.
While not necessarily felt by the wearer, the stone may be damaged when slid onto a regular mandrel.In these cases, the grooved mandrel can be used.
Line the stone up with the groove in the mandrel to protect it and get an accurate size of the ring.
