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.

A ring comprising:
- a first ring shank having a setting located at one position on a periphery thereof, said first shank having a first shank central axis central to a first shank finger hole, said setting including a gem setting receiving hole open to both an outside of said ring and open to a first flat side of said first shank ring, a cross section of said gem setting receiving hole viewed from a point along said first shank central axis above said first flat side of said ring includes a first hole width at a first location within said hole, and a second hole width located outward from said first hole width, said second hole width being narrower than said first hole width;
- a second ring shank having a second shank central axis central to a second shank finger hole, said second ring shank being adjacent to said first ring shank;
- and
- a pin generally parallel to said first shank central axis and said second shank central axis connecting said first ring shank and said second ring shank, said pin being configured so as to allow said first ring shank to pivot relative to said second ring shank around said pin;
- wherein, when said first ring shank and said second ring shank are disposed so that said first shank central axis and said second shank central axis generally coincide, considered to be a closed position, a portion of said second ring shank covers said first flat side of said gem setting receiving hole.
