I have rhinestone dress/shoe clips.   They measure about 2 3/4" across x 1 3/4" in L .  They do have a curve in the frame to add to the style.    There is 1 stone which looks like it may have been replaced but is slightly a different shade - the 4th photo shows it the best.  These would be a great dress or bridal accessory.  The rhinestones are all in there own settings.
