The #2 Conner Pliers are especially helpful to set or tighten side stones in a basket setting as well as on other type of mountings. One side of the pliers has a slot for the wire under the stone and the other side has a beading tool cup on it. Also great for setting earrings - with or without under bezel wires. Simply slip the post through the slotted side and bring the beading tool down on the prong making this type of work much quicker and easier. Perfect for setting the tightening accent diamond surrounding color center stones.
