ABSTRACT:
A method is disclosed for modifying the surface of an item of jewelry having a cylindrical outer surface. The item of jewelry is advanced axially successively through a cutting station at which a cutting tool provided with one or more cutting elements each having a cutting tip are rotated relative to the item of jewelry generally about an axes coaxial with the elongate item of jewelry. The cutting tips project beyond the cylindrical surface of the item of jewelry and, therefore, scratch, cut or displace the material from which the jewelry is made to generate a plurality of reflecting surfaces in the case of a non continuous cylindrical surface and one or more cylindrical grooves in the case where the item of jewelry has a cylindrical surface. By controlling the linear velocity of advancement of the item of jewelry through the cutting station and the relative angular velocities of the item of jewelry relative to the cutting elements different quantities and patterns of reflecting surfaces can be provided. The method produces items of jewelry which have enhanced sparkling or glittering properties.
