Abstract: A ring with an interchangeable gem mechanism is engineered. The ring comprises a loop having two termini. It includes two shoulders, each shoulder resting on a terminus of the loop. It additionally includes a bezel resting on the shoulders that is configured to contain an open-worked chamber. The ring also includes a diadem that is configured to be housed in the open-worked chamber but is separable from the bezel. The ring further has a key that is configured to insert through a front of the bezel to lock the diadem in the open-worked chamber of the bezel.
