ABSTRACT:
A ring having two shanks which pivot around a pin parallel to the finger holes through the two shanks. One of the shanks has an gem setting receiving hole which receives a center gemstone prong setting when the two shanks are in an open position. When a center gemstone prong setting containing a center gemstone and a prong setting base is introduced into the gem setting receiving hole and the two shanks are moved to their closed position, the escape path for the center gemstone prong setting is blocked and the center gemstone prong setting is locked in place. Locating the pivot pin closely adjacent to the setting provides a significant mechanical advantage to carry loads of large bezels and/or gemstone clusters around a replaceable or interchangeable centered gemstone.
