A METHOD FOR MAKING A HOLLOW RING-SHAPED JEWELRY ITEM ESPECIALLY A RING. THE METHOD INCLUDES ASSEMBLING AN INTERNAL CYLINDRICAL PIECE (2) THAT DEFINES AN INNER PERIPHERAL SURFACE OF THE JEWELRY ITEM WITHIN AN EXTERNAL CYLINDRICAL PIECE (1) THAT DEFINES AN OUTER PERIPHERAL SURFACE OF THE JEWELRY ITEM, THE INTERNAL PIECE HAVING A SMALLER OUTER DIAMETER THAN AN INNER DIAMETER OF THE EXTERNAL PIECE, SUCH THAT A GENERALLY ANNULAR HOLLOW SPACE EXISTS BETWEEN THE INTERNAL AND EXTERNAL PIECES; AND CLOSING OFF THE HOLLOW SPACE ON EACH SIDE OF THE ASSEMBLY BY JOINING A RESPECTIVE SIDE PIECE (5) THAT BRIDGES THE NEIGHBOURING EDGES OF THE INTERNAL AND EXTERNAL PIECES. PREFERABLY, THE INTERNAL PIECE (2) AND/OR THE EXTERNAL PIECE (1) EACH FURTHER COMPRISES PROTRUSIONS (3) THAT EXTEND INTO THE HOLLOW SPACE. THE PROTRUSIONS (3) EXTEND RADIALLY BETWEEN THE OUTER WALL OF THE INTERNAL PIECE (2) AND THE INNER WALL OF THE EXTERNAL PIECE (1) IN THE ASSEMBLED JEWELRY ITEM.
