ECONOMY STEEL RING MANDREL with GROOVE
Solid steel mandrels for checking the size of rings. The steel is strong enough to handle blows from a hammer when shaping or sizing. This mandrel features engraved markings for ring sizes 1 to 15 (US) in 1/4 sizes.
This mandrel has a groove that is useful for rings that have stones set low in the ring with the culet exposed underneath
