Means for the adjustment of rings or other similar gold and silver articles of jewelry and costume jewelry

The present solution permits to carry out rings according to an only size typology since such rings are then adapted to the personal requirements of the customers, there being no need of cutting and soldering an annular portion. Basically, the said means is represented by a coupling head ( 2 ) which may be provided with seats for the setting of stones ( 3 ) according to the most suitable uses and conformations for the customers and market. The coupling head ( 2 ) is provided with at least an inner seat ( 4 ) for the insertion of the real ring body ( 5 ). The ring is open at least to a certain extent and therefore, it shows two free ends ( 6, 7 ). One of the two free ends ( 6, 7 ) and more precisely the ring end ( 7 ) is fixed to the initial part of the said seat ( 4 ) while the other ring end ( 6 ) remains free and is displaceable along the seat itself to permit an adjustment of the ring according to the wished size.
