Achieve professional stone setting results with these pliers. The complete kit consists of a plier and an accessory set with 4 stone setters and setting holders. The plier can be used independently to close prongs and tighten them. The 4 stone setters are for sizes 0.02 carat to 1.00 carat stones and attach to one of the jaws of the plier. Simply place the setting between the jaws, align the setting below the correct size setter and with a quick squeeze close all prongs evenly. To set an earring post, place it into the setting holder. The opening of the jaws is adjustable and the depth is guided with the “depth control” nut so that you always have complete control of the distance and amount of pressure.
