Prong Opening · Prong Closing · Prong Tightening · Hook Jaw Conner — Complete stone setting workflow in one professional set. Diamond, claw, snap set, and ring repair.
Grips the shank or body of a ring, pendant, or brooch securely while you work on the setting from above. Eliminates the need for ring clamps, bench pins, or shellac during wax model work and heat setting tasks.
Thin claw gets in behind prongs without touching the stone. Notched lower jaw grips the prong securely so it does not slip during opening. Applies lateral force from the side — not pressure onto the stone crown. Safe stone removal from damaged settings.
Angled jaws match the natural closing arc of a prong. Rolls the prong tip smoothly over and down onto the stone crown — no slipping, no scratching, no lateral pressure on the stone. Works on four claw, six claw, crown settings, and tennis bracelets.
One smooth jaw and one grooved jaw. Grooved face locks onto the prong without slipping during tightening. Use for routine loose prong maintenance, final tightening after setting, and pressing prongs into snap set and pre-made commercial mountings.
Thin claw jaw — impossible with closing or tightening tools without slipping off the prong
Angled jaw rolls prong over the crown — grooved jaw would scratch the stone surface
Grooved jaw grips existing prongs without slipping — thin claw jaw lacks the grip needed
Hook jaw conner holds the piece steady — frees both hands for setting work
