Abstract: A display case for displaying jewelry items or the like has a rectangular base unit with a base wall peripherally bordered by an upstanding frame section. A rear end wall of the frame structure is removable to permit insertion through the resulting frame opening of a display insert structure configured to support jewelry items such as rings and bracelets. As the display structure in inserted inwardly through the frame opening, opposite side edge portions of the display structure are slidably received in inner side surface grooves in the opposite frame side walls. When the display structure is fully inserted into the frame interior, the rear frame wall is reattached to thereby give the inserted display structure the appearance of being permanently framed within a dedicated display case.
