Abstract

Abstract Means for reducing the diameter of a finger ring to produce a fit secure and comfortable for the wearer. The ring is fitted with a relatively flat member directly beneath the setting facing inwardly of the ring. This member may be constructed of a magnetic material or may be of a material such as iron which is attracted to a magnet. The member is secured by means of a suitable adhesive or by soldering or the like. In order to reduce the diameter size of the ring, a disc-like shim, which may be a magnet, is positioned on the underside of the secured member. The shim, is not adhesively secured but is secured to the member by magnetic attraction so that if the member is a magnet, the shim need not be, but can be of an attractable material. Shims of varying sizes may be employed so that the diameter of the ring may be modified over considerable reductions.
